Understanding Drupal

good morning everyone this is

understanding Rupa thank you very much

for being here

my name is Martita lien act I am known

as dinner Conan drupada or Twitter and

pretty much anywhere in the Internet I

am from Nicaragua

it is 88 degrees there right now and so

if you ever want to escape the call of

the Midwest that's a beautiful place to

go and you can get really hot like we

have active volcanoes and you can either

watch like an online experience or

actually leave it if you go to Nicaragua

I worked with a company called I got it

which is based in Boston where we were

actually distributed

I am from Nicaragua but have people in

Europe and America as well

and I am really passionate about

teaching I've been doing this for a

couple of years already and in the

future I'm going to start a project to

teach in Drupal in different languages

so hopefully that will come out soon and

I will start with English Spanish and

French and I am already expecting to

learn German so at some point Germans

well this is an outline of where we're

going to cover today we're going to

start with the very basics like no

assumptions not even true palates

Pacifica stuff and from there we are

going to you know build concepts

understanding so to start just like very

general thing the difference between a

web page in the web site so usually

those terms are used interchangeably but

they are a little bit different so when

you have a website let's say you know

amazon.com that had pages for individual

products and offer some services and so

on so the website in general is

amazon.com but then you have a specific

pages for each of the product and each

of the other things so in this case we

have one web page that has

excuse me one website that has six

different web pages and for example in

the article section of your company

organization for example you can have

one extra page for each individual

article so this is going to be useful

when we learn how to map that concept

that we might know already from using

the web in general and how those things

translate to Drupal and when we you know

look at a web teaching in particular we

have like a fuller hair sidebars lows

and so on main with navigation and

things like that so my objective for the

session is for all of the elements that

we see on a web page understand what

true power holders and understand how

you can modify them if you need so you

know before we start why do why do we

want to use Drupal anyways so let's see

some examples until a few months ago the

White House was built on Drupal and that

was the case for several years you know

they change to another play but just the

fact that it was running Drupal for

several years is already approved that

Drupal you know is secured at the very

least

whether that count is also a bill on

Drupal and this is actually like the

biggest drupal website it serves over 1

million visits per month and this is not

only through the website but also

through web applications like if you

have that on your phone you know you

want to know what is the weather like in

Chicago right now it will actually

connect to a Drupal packet that Ronnie's

is also build on Drupal and the

interesting thing about this one is that

the rain of the event the whole thing is

like live stream and you also have

direct registration interviews photos

you know written articles are you and

all the multimedia

one single night with massive traffic

from all over the world Drupal can

handle that easy economic forum also not

very edited but at the top right we have

a language sweet future so your Drupal

site can be multilingual

and you know there are a lot of

functionality out of the box but if you

want to invent the pirate language for

example you can do that XO minor tongue

this creature was supposed to show the

responsiveness of Drupal but this is

Krisha so it doesn't respond to anything

but in theory depending on the device

that you're using it is phone a tablet

desktop computer or even a quirky

monitor the content of the website is

going to adapt to you know use as much

space as possible and use it in a very

optimal way and then I have traditional

regalia so this is a small business in

Spain 15 Barcelona where they you know

they have an online store powered by

Drupal to say send a products they sell

oranges tangerine's sweets

honey memory and lemons so yes Drupal

can power you know really high profile

websites but it can also power your own

small business or your own you know

nonprofit organization or your own pride

Tesla Motors is also village robot we

haven't made it to their cars yet but

rumors have said that you know we just

put a patent heavy and space and some

weight report was helping doctor and in

general these are some of the features

like just to recap security multilingual

support ecommerce integration high

traffic you know

management responsiveness of the content

and media handling so hopefully this

will you know give you some clues why a

lot of organizations are not through any

practice in particular universities I

know that in the States at least they

use heavily Drupal and other countries

like externalized on the Drupal platform

for the government sites for example

Australia and Germany the government

sites most of them are lot of trooper so

another few skaters for the educational

role and tech sectors and maybe I

persuade you to to use Drupal but what

inequalities depending on who you ask

Drupal is different things I'm going to

talk about three today but I wonder

we're going to focus is this one Drupal

as a CMS so as far a CMS that is nice

for a content management system it

allows multiple people to participate in

the creation of content and on top of

that it allows you to create publication

workflows let's imagine that the work

for our newspaper you know we have the

journalist who writes the article but

this needs to go through a review

process because before it get it gets

published on the website so we can have

for example one person that normal is

reading the article but it cannot make

it public out of the box then we have

the editor which reviews and make

modification the editor is not able to

create but he or she is able to modify

what someone else every wrote but let's

say that in this case we need one final

check or approval from the department

chief before things go live

so the editor will pass along the

article to the next person and that the

furniture this person is not able to

create or modify content only to check

if everything is okay and if that is

okay if that is the case make it public

so you can have very

I'm great controls over who can create

modify or delete content uneven you it

like you can define who has access to

that content that is it is already

available you can also have contacted

easily and this is how triple names the

way to track changes on the on the

content that you create let's say that

you know something wrong goes to the

website you know something user either

made a mistake or did it on purpose

Drupal will keep track of all the

changes that you went to the website

like another PI letter image pretty much

anything that you do Drupal analysis

comes enable or after the box it will

keep track of those things and it will

tell you when the change was made like

date and time and who did it so you know

if it was a mistake you just like revert

back to that previous version of the

content and what was it if you do ask

you know on purpose that something put

something improper on the website you

can do the same you can be very back to

a previous revision and then you can

blow the user so that user does not have

access to do more hang on the website

and you can have very very granular

access controls let's imagine that we

have our e-commerce website and we want

to show that content exactly the same to

everyone but we have some VIP customers

you know they buy from us frequently so

the Dakotan is going to be the same

except for the price if it's just like a

general

they see the regular price but if if

this is like a reactive customer they

are going to see the price with at least

one already applied so the images by SKU

the product description like the product

name everything is going to be the same

except for that price itself so the

possibilities of you know managing

access controls in Drupal are create

very flexible framework and one thing to

remember it is that if the file does not

solve your need out of the box you are

free to extend it you know through

programming to do exactly what you need

so it's extensible buy it by design and

probably one of the most important

things to me I have no Paulista

community so you know lots of people

from all over the world participating in

making Drupal better it is it has been

around for more than 15 years so it's a

solid product already and just the fact

that I came here from Nicaragua to

present this session you know it's a

testament that we are a worldwide

community and in the in the Chicago area

you know that a lot of companies that

work with Drupal there are initial

groups that happens that like have

meetings at least once a month so if you

really want to get into Drupal

I highly recommend that you get involved

with the community sometimes like when I

started it took me about six months to

learn what I'm going where I'm going to

teach you in an hour so I remember going

to my first meetup on yeah hi I have

been banging my head against this

problem for days and I just asked

someone else with the experience and in

less than five minutes I had a solution

so try to get it back with the community

so some basic concepts and again I feel

free to interrupt me any time if I'm

going too fast just let me know so the

first thing to know about

police what we call core so core is the

minimum package that you need to install

in order to have a trooper price if you

don't have core it is something else

dupa core comes with a lot of things the

two most important ones are modules and

themes and we're going to cover them in

a moment

and it is called the thing that serves

at that framework so if you want to

extend trooper to something else

Drupal core explain to provide you the

tools and the mechanisms to achieve that

so we said that we have modules and

themes with Drupal for what is the model

our model is something responsible for

adding functionality to your website

let's say that you have a personal blog

and every time that you publish a new

article you want something to happen

that something might be sending a tweet

or a manatee or posting to your Facebook

wall up automatically anything that has

to do with functionality is provided by

a volume on the other hand we have

themes themes control the appearance of

your website like the layout how it's

going to behave in different devices

like the color scheme the phones to be

used all of those things are controlled

by by by things so there is mostly a

very clear delineation of the

responsibilities functionality those are

provided by models appearance those are

provided by themes and remember this in

the context of 2.4 look like corn chips

with curly 50-ish modules not all of

those are enabled out of the box because

you know Drupal is supposed to be

generic and not all the website will

need all the things that Drupal can do

so both modules and theme can be enabled

or disabled on demand

depending on your specific use cases and

this is a Drupal core part of the box

but you know again through polish meant

to be extensible and we have something

called the country repository

country in this context stands for

contribution and this is code that

people at you and me that participate in

the community have been available for

everyone to use let's say that you know

through blackboard for example doesn't

have an integration with PayPal out of

the box but there is a lot of use cases

where you want to interact with PayPal

so there were a group of developers who

you know dedicated some time to write

that integration and created a module

that will allow you to accept either

payments or donation through PayPal and

in medium they make the module available

in the content repository for everyone

to use the same applies for themes and

something that is called distribution so

Drupal can be used for so many different

use cases and sometimes you just need

like a an extra layer of configuration

bundle out of the box so those are

distribution this dilution are a prefect

expression of Drupal with modules from

the country repository and themes from

the cosmic repository that are already

pre-configured for example we have one

called common kickstart that if you want

to expand it from your solution on true

pal you know you can go download through

procore and some modules and some things

and do yourself the configuration or you

just download the distribution and it

comes like out of the box already

configured to have a you know current

workflow discount shipping and so many

other things another example of

distributions there's one called

open Church for churches open open

outreach for NGOs and there's also other

distribution for Qatar for like

newspapers or the Mormons

or and so on so all the things that you

try to get from Drupal for different

reasons do it from Drupal ductwork so

contrary to other place like WordPress

where you know there is a big ecosystem

of premium themes and you know just go

to this website and download these and

go to their website don't know that it

trooper that or we try to centralize

that and mostly for security reasons

there is a team of probably 45 or so

people around the globe that they focus

on keeping that code on drupal.org

secure there are some guidelines around

that for but pretty much if if you have

if you see a green shield for for Drupal

or a model or a theme or a distribution

you know it is covered by the security

team and that recommendation anything

that gets on the front for Drupal Drupal

at work and the only time that you want

to them

is that if when you go to the pad at

work they point you to some other place

to download something in which case you

need to you know do some checking but

that's the general recommendation so

we're going to get started with you know

the CMS the content part of things any

question okay so I'm going to be making

it stop after every section and if you

raise your hand understand that if there

are questions otherwise I will just

continue so the Drupal has been around

for a long time and sometimes it uses

some terminology that is not very

alienated or self-explanatory

one of those is the word know so what is

a note I know it is a piece of

information that can tell a story by

itself and then now serves like the

basic element that's going to be used to

store information and Drupal so let's

say that we have this card

what can we tell

this card it is a red card it has two

doors four wheels and you know I can say

that make that one of the year so many

other properties so the note is going to

be this piece of things where I'm going

to store this information it's going to

be a container this is an example of a

note in RuPaul and there are some

properties that are common to every note

in the in in a Drupal website for

example every note has a title that's

mandatory

every note also has an author and a

publication date which includes like

date and time every note has a URL so

you know it has to be in EPA identified

in some way by the system and that is

called node ID for an ID for sure know

for sure

thanks I know where the node IDs a

number but it starts with one the finish

time that you create a node and it

increments by 1 every time you create a

new node so 1 2 3 and so on but let's

say that I wrote a very interesting

article a nice I tell you I'll go to my

website I think that comic slash know it

slash 1582 right by the time that you

get home you might have already forgot

that so in addition to having these node

IDs to be able to reach and note on that

other page we also have something that

is called URL aliens so just like more

like human readable way to call to call

a note like in this case it is the comma

slash blog it's large artery in this

resolves that may be easier to know if

you understand like the context of what

I'm talking about and there are many

other properties like if I notice either

published or not published for example

but you know this is kind of the

baseline of of what I know I notice

about

okay so we've note we are able to store

information about cars again like gear

make modern type of fuel number of doors

number of windows and so on we can use

an O to describe a car fully but in the

in real life different objects have

different properties for example you

know we have cars but but other things

have wheels we can have motorcycles

bicycles three cycles in addition to

cars and in real life these things have

you know very different properties for

example as far as I know we're psychos

cannot be worse for a motorcycle it

doesn't make sense to say how many doors

or how many windows they have so when we

have in real life some concepts that are

very different from one another yes they

are all going to be stored in nose but

we need a way to differentiate and a way

to differentiate from for example a

motorcycle and a car in Drupal it's good

content so this is like a second layer

of abstraction coated that is you know

this abstraction that will allow you to

give notes that share similar

characteristics or the stripes the same

idea and by this you know this can be

physical things like cars or motorcycles

or you know if three cycles 1o seconds

or things like that but it can also be

non touchable things like events so this

event had a day had a registration price

it has a location for the event and you

know so many other properties so you can

use a content like to describe an event

and then you know we store that

information in Drupal you can also have

for example article the article list can

be also a prototype where you have you

know the title tagline an image and

Quantic cotton itself and you know many

many examples and we're going to see

others along the way but other than you

know making these grouping of nodes

there are way that content network they

also allowed to ease the management of

that of the information on the website

let's say that I am an online dealer

when I sell motorcycles and cars I can

have in my website are a specific page

that lists all the nodes in my website

that a lot of the current content type

so by that I already like sort out

everything else like motorcycles I can

have another place where I only store

information about motorcycles so you

know show all the nodes in the website

that are this motorcycle container and

at this point you might be confusing up

so you're talking about nodes and

content types what's the relationship

between them and this is very important

to understand so every node is someone a

specific content that you cannot have

one node that we don't do for example a

car and a motorcycle that's not possible

directly around that is possible and

actually expected for example you can

have a car content type that you're

going to use a sub template to a stone

information aboutdifferent currently 10

have a quantitative article that will

save as a template to store articles on

the website and you will have many of

those so one node belong to the water

specific content type one content that

can have many notes associated with them

and in this image the numbers in those

blue circles represent the variety and

if you see throughout the image those

numbers are not repeated because no

deities cannot cannot be repeated they

are unique and in fact if you delete one

for example if I D

no number 2.21 we reuse like it will

always keep incrementing and things

delete it won't be reused so this is

like really important to understand like

these two concepts are like the basic

for everything else in question okay so

we we you know we have this online

dealer and we are not able to separate

all the you know cars from all the

motorcycles in this in this page I only

want to show cars but most of the time

when like someone is looking for a car

or in general just searching for

something they look for a specific

attribute like in the case of a car I'm

a one you know a toyota yaris 2010 red

for example so I am looking for specific

things just having these you know long

is all the cars in my website is not

enough so I need to be able to do a

specific search to search on a specific

attributes so the way that we accomplish

this in Drupal is using fields and

fields are awesome I used to have a very

long boring and the scripture is like

here which I'm going to show you later

but before showing that I want to

explain the awesomeness of fields so

anyone here has ever use either Facebook

or Twitter some people so let's let's

focus on Facebook for the moment when

you are going to write a fake facebook

post you are basically free to do papers

for everyone you can write a poem you

can you know just go ranting about

things you can think people you can

imagine videos you can you know please

type anything like random words in the

numbers basically if you're free to do

whatever you want and with tweets it's

about the same you have a lot of freedom

in the way that you enter the content

but this model

some work when you try to look for

something and you try to search for

something let's imagine that you know

this dealer business also has a Facebook

page and you know they are very

successful every day a new card comes in

an old car drops out of the inventory so

you know people will interact you know

this is the photo this is a red-letter

Yaris 2010 but every day that's going to

be you know going more postman post and

even though both Facebook and Twitter

have search functionality if you have

ever use it in for this use case you

will know that it gets really hard

easily because of many reasons one of

these reasons is that free text is not

easily searchable so people can write

whatever they want in whatever it's

tight and format day one and that does

not necessarily match the user criteria

like they might you know just think

differently or not use abbreviations or

things like that so the free text is

hard to search also when you have free

text and that freedom you are also able

to enter in consistent data like you

know when this event happened it

happened on of airplane 19 2017 or you

use Nov with the dog on a radiation or

you use like numbers instead of letters

to describe a month or for the year you

put two digits instead of four or you

use a - instead of five - yeah - instead

of a slash for that separator or if you

are like in Nicaragua we put a day

before the month so each person entering

the content might do it in a different

way and good luck trying to you know use

Facebook or Twitter to understand what

you enter if the person who were in

early folks at you know the post for the

tweet use something else it's not very

hard it's not very easy excision

also you can enter inconsistent data

putting Banita

and this is going to make people cry so

how are you - ten years old that make

any sense

when is your birthday February 31st that

doesn't exist

where's the prize so I use the dollar

sign but the euro currency once your

email no not a real image your miss

cannot sign when it's the phone hi

beautiful happy face that's not even a

number so again because you are free to

do whatever you want you can do those

things very easily and you know

consequences I guess so oh I'm going to

make you poor try free tags

inconsistent data and invalid dinner so

how do we make people happy because we

want you know to put happy so people can

find the stuffers we do that using

fields so fields are able to enforce

validation criteria and there are many

different type of fields we're going to

cover some of them today for example on

the right we have an overview so for an

offer field let's say that this is the

price of an event like this one I got to

point and we can say that the event

might be free but I'm not paying someone

to come to my event at least not today

so the minimum value for the price which

is going to be zero from zero I don't

define a maximum because if someone is

willing to pay a million dollars to come

I will greatly accept it we are in the

stage right now so there is no need to

confuse people or to ask people about

currencies we use dollars all over the

place so I make it very clear and

specific dollar sign us the critical and

anyone both entering the content and

then consuming the content will

understand that I am talking about

dollars are not Europe or corridors

getting in trouble so and in this case I

can make this field required so I cannot

be

then without a specific I specify not a

price on the on the other picture we

have an image field so for an image

field I have different criteria to

validate for example what are the allow

file extension like PNG jpg gif and so

on for example if either one people

uploading animated gif of cards on the

website that this will give from that

list and Drupal will validate that those

things cannot be uploaded I can also

define like minimum or maximum

resolutions I can also define maximum in

our file size and other things not one

important for accessibility reasons I'm

a little bit for SEO as well is the alt

attribute so sometimes when an image

cannot be displayed for some reason

maybe it's not available anymore or

there are a lot of images and they are

not loading quickly so there is

something called alternative text that's

going to be used while the image is

loading and with with a field you can

actually enforce that to be entered and

that is not only life of course it is

supposed to be meaningful because for

example someone using a speech reader on

their browser they won't be able to want

to see that picture understand the

picture but if you put some meaningful

text they will at least have a sense of

what you're trying to convey with the

image so you can enforce all of these

things with fields and again there are

different type of fields and using that

makes people happy so what is the recipe

for happiness you use one field for each

piece of information that you want to

restore

let's go back to that example of cars

you are going to use one field for the

year one for the main one for the model

one for the type of fuel one for that

type

for the number of windows from the

number of doors and so on anything that

you want to store you're going to use a

specific field and after doing that you

need to also decide what type of field

is the one that you want to use because

as I mentioned before each of them will

provide you with different validation

criteria in blue but we have integers

decimals images phones in and URLs and

all of these come with out of the box

validation so if you want to enter you

know an email that is missing that side

for example Drupal will stop you right

away he won't allow you to save the node

because you're missing something and so

this with this ability now fields are

also are also also in the way that you

can ask for information and display the

information after afterwards so let's

think about you know an event like this

one I'd look at them it has a location

how many different ways exist to

represent a location you know a point on

earth at least for it so you can

actually put like the name like link

home Student Center you can also put

like that lucky to technology took on

the globe you can display a map and ask

the user to click on the map to identify

the location but also like in the same

way that we have PDF for Word document

some four months document format uses

specifically to restore geographical

information when if those is called KML

so in theory I could provide a field

where they upload a file like instead of

opening an image they upload a KML file

that stores geological information and

then Drupal can read that information to

others to understand where these events

happened so one field can provide more

than one way to collect the information

in practical terms it doesn't exist in

Drupal our field to if to collect

geographical information that allows for

this for but combining different

contributed mornings you can accomplish

this functionality if you wanted but

pointing to remember is that you have a

field and the field exposes in many ways

to collect the information and once the

information is collected it is storing

this in in a standard way so you can

present it any way you want as well so

maybe you asked for latitude and

longitude when requesting well when

displaying to the user

you show a map with a winner marker so

the way that the information comes in

it's not necessarily the same that it

comes out you can change that as the

field allows you to do where each field

will define how you can enter and how

you can display information but more

importantly you can aggregate the

information so maybe you have a lot of

events you have a lot of events and you

want to show a map of all the events

happening at the same time so you can do

this again with fields and this is a

real website for Drew Pakal so another

you know test that Drupal is worldwide

these are events happening all over the

place all the time so one thing

interesting about this website is that

it combines information from different

fields to to show them up for example

there must be a

I feel that explore the location which

is where the pointer is going to be

played on but you also see that it is

color coded so there is an honor field

that defines what type of event disease

and we're combining doctor

things to show a marker that has a

specific color on the map and other

things that can be done fields can be

shown or hidden individually so you can

have for example an event that has ten

different fields but you were you didn't

notice it but someone came a few minutes

ago to tell how many people attended

this session so this information is

really only for the camera organizers

but probably not relevant to us

attendees so you can have a field in

that session a content type that say how

many people attended but that's going to

be hidden for the general public and

only that camera organizers are going to

be able to see it so you can have you

know that contact ID in your template to

collect information you can have a lot

of things but you're not required to

show all of them or you can decide for

these people I show some elements for

this other group of people I show

different elements so it is very

flexible and you are able to do this on

a field by field basis yeah some general

examples single line text field

multi-line text field those were

different in profile we also have

numbers so when it says establish in

because I is supposed to store right

here and here are only numbers and not

only numbers only integers you don't say

in two thousand six point five so but

when we configure is field in the

configuration we were able to define a

prefix so that every time someone enters

the content oh this is about when this

organization established and when people

see that content oh this is what you

know when this is when you see someone I

started so it is very clear and because

it is a number field you have all the

validation that

we also have URLs taxonomy is no

birthdates time someone there are likely

trying like doses of pills available and

all of them in court and many more in

the contributed space so this is the

slide and fields allow you to structure

the information of your website

they said discrete pieces of information

like the year that make the model and so

on and once you have this information in

fields you can display them in different

formats you can filter what elements you

want to show or not you can sort that

information in any way that you might

want you can take for example I want to

show all the cars sorted by the year

like the newest configuration for

example so so far we have only talked

about the center the middle part we have

known where this knob is one specific

content type let's say an article it has

a pedal a title and an image and the

description but what about the rest what

a lot of all the squares around out the

middle in this image everything else is

a block so what is a block in Drupal a

blog is a container of extra information

to display I know the main content of

the page

you know the main page content is you

know but everything around it those are

gloves and a little bit of a segue

before talking one of our blocks is that

they are always placed in the theme

region so if you install Drupal out of

the box it comes with these blue

appearance and that is that a core team

called party-party defines many

different regions each of them is

represented by a yellow box in that in

the screenshot so whatever you see

what that means you can place blocks in

that place you can place content there

remember that the English the one

responsible for controlling how the

different layout is going to behave so

for example mark has a region called

featured table that has a great

background if we start but out of the

box we never see that gray stripe why

because out of the box

Drupal doesn't flake place any block in

that region so Bartok decides to

collapse it because I've seen a region

means to hide so if there is no content

there we just had and the same happens

for the left and right sidebar if there

is no content in those regions Bartok is

going to expand thus that to the content

region which is the middle one to use

you know all the space available at the

bottom where we have the black

background on you see four boxes one

next to each other

the those are fully regions and in this

case but it doesn't collapse them so if

you put a block in the footer region if

we not expand an automatically if the

other ones are anything so remember the

way that the theme is going to behave

over the site's way to behave in terms

of layout that is going to be determined

by the theme now let's talk more about

blocks lot can be either I started or

dynamic so this refers to that content

or the information that they are going

to display let's say you know we have a

copyright 2018 at the web page there is

something that you want to change once a

year so you know general sense there is

a static content so something is going

to be the same or almost the same all

the time then there is a static load you

can also have dynamic blocks these are

things that change regularly like the

latest blog post if you publish

something every day

going to be changing every day if you

publish something every hour that's

going to be changing every hour and a

lot of these things can be automated so

that you don't have to do anything

manually other than creating the content

you create the content and automatically

the blog gets updated with the latest

information blogs can also enforce

miscibility rules so you can say this

blog only makes sense in the context of

an article for example if you have more

articles written by the same author if

you go see an event it doesn't make

sense to have more articles written by

the same event so you can define

disability locks based on content types

you can also do it based on language

maybe this only makes sense in the

Spanish version of the website you can

also do it by pages like this only makes

sense in the front page in the contact

page in the marketing section of the

website you can define rules based on

the on the path or the section of the

website that you are visiting and you

can also do it by roles and we're going

to cover those later blogs can also be

aware of the environment so let's say

more articles written by the same author

when blooper is going to display this

blog is going to see okay I am going to

show this for node 5 node 5 was written

by Mauricio so let's look for more notes

written by Mauricio and show them me in

this blog so this is also possible and

similar to content types

blogs can also have fields and this is

new in Drupal a Super seven you have to

use a model called green ve am to have

blocks with fields the Drupal a this

comes out of the box and you know one

useless can be you have this a special

offer block that has four fields a title

a description a new Mexican an

expiration date and you know lots of

this type are going to be shown on the

sidebar always until the expiration date

comes so you can define someone clay

using gloves and everything that I

mention about feels before I applied for

blogs and applied for other things as

well another very important concept for

Drupal is views so we can literally

spend the whole time talking about deals

but we don't have that time for that so

I'm going to show you two slides and try

to explain use as much as safe as

possible so in group and give us a way

to release information so tuple is a

listing of information on the website

that can be a list of knowledge and it's

of users comments content that and

fields anytime that you want to make a

list of something chances are high that

you might want to insert before that and

what is the job of a view I'm just going

to ask on all the content of your

website and you can use it to also to

filter what things you want to show like

I want to show all the cards that I read

what our Toyota the archives you can use

views to define the search criteria and

once you find all the notes that match

your criteria you can define different

ways to present the information so you

can have an HTML table or you can create

an RSS feed for that or you can download

a PDF document with that listing or a

CSV or Excel spreadsheet or you know as

we saw before you can have interactive

maps images light shows and many other

things so that news views collects notes

or other type of information on the

website and display them in many

different forums we have an example here

in this case we have a view with for 4

with 5 columns a couple of things to to

know I am showing field information here

and for example the first column has the

played the year the

and the model remember the

recommendation you need to use one field

for each of this stuff but we and then

it's that case like under the hood you

have a Content plate with fields

individually for each of those elements

but when you display the view you can

actually modify how it's going to be

presented and instead of each of those

using one coordinate you just can put

them together but you also have images

and one interesting thing about images

is that Drupal has a mechanism to

pre-process them automatically let's in

mind that you know we are all work for

this car dealer and we take pictures

with our phones each phone is different

you know different resolution different

quality and manual properties but when

displaying on the website we want to try

to be as consistent as possible so in

Troopa we can have a way to say okay no

matter the size of the image make it a

smaller no merit aspect ratio naked 4 by

for greatest scales or other image

aspects so no you just define I want to

apply these effects to the image and the

probability neuromarketing another thing

that is possible with you you can define

like a default way to present the

information but you can also allow the

user to modify that criteria to their

needs so above the table and below the

text access cards we see some like text

boxes those are called views exposed

filters and they allow you to you know

the user to say okay I want all the cars

representation is going to be updated to

respect that I want to show only Cleopas

I want to

on the Yaris they want to show by year

descending for example or ascending like

the newest fear sort out the fears some

of this is possible because we use

fields so things are going to allow me

to want it to to expose certain search

or or filtering criteria or certain

criteria for the user to you know to try

on the top left we also have a small car

only one and there is also a view in the

feeling just a moment ago I said that

views are used to show least something

and when I think of the word listen it

is two or more elements but in this case

I have a view of only one element and in

some cases cases that make sense if you

read the text it says random car so you

can define a view that shows one card

only but randomly every time that you

refresh the page a new car will appear

another use case for this kind of a

scenario when you have a listing of only

one element you know it can be the most

popular article the most committed

article the most visited page on the

website every time that you have the

most of something or the best or you

know things like that you can also have

a view that shows that way the

top-ranked and just to clarify bills can

be used to show like the main content of

the website like that table but views

can also be used to create blocks so in

the top left that was a lot created

using a view now you might ask why so

much clear I mean I thought that people

was hard you're not confusing me with

all these concepts it is really

important to understand all these pieces

because

yes so we go if you're a front-end

developer and you want to print one line

of text you will have like 10 level of

deeps to accomplish that if you are a

developer you will have pretty complex

data structures that are like one

instead of the other to accomplish what

you need but what is relevant to us

Drupal nest concepts so all the things

that we have talked today note content

type regions have blocks views all of

the all of them interact together to

fill a page so let's imagine we have

this piece of information more articles

written by the same author to create

that we were at least interacted with

five different concepts on the almost

layer we have the theme region so this

is going to determine where this

information is going to be displayed

let's say the theme region is the right

sidebar because this is complementary

stuff accounting like more articles

written by the same person this is a

blogging itself so I have that blog more

articles by the same person because this

is a listing the listing was was created

using a view that view was configured to

show articles those articles are of one

a faceted content type but only the hood

those are notes in and let's say that I

want to show like the title and tagline

and the date of when the article was

published those are individual fields on

the known so for one small piece of

information I am already interacted with

five different concepts and each of

those is going to behave in a different

way it's going to be configured in a

different way if you want to modify this

you have to go to different places so

it's very very important if you going to

remember

of the session remember this image when

assembling a Drupal page under of

concepts are going to interact

simultaneously for example I might want

to show you know all the users of my

website I can replace the blue box from

node and say show a list of users for

example what I want to show at is I

started blog I would only have a future

and a blog and I don't have all our

inner layers the point being that for

everything that you shall wanna do per

page there will be many things interact

at the same time and with this now we

have seen like the mail that the mill

can be either unknown or it can be a

deal and all the things are round

those are blogs that are built in

different ways there are many ways to

build laws so I mean this is very

important any question with that so as I

said before for each of those things you

will have different section of the

website of the local administration our

interface when you are going to modify

how they behave so it is super important

to understand what they are to know what

they are so users let's talk about users

a user is a visitor to my website anyone

that goes to my website is a user for a

Drupal

again look I can handle multiple users

as I said before show an example all the

users have a user name have an email

they optionally can have an image and

you can attach fields to use of like

again

because it the right display about

fields for content types

for blocks users can also have fields

so in this case I I have a bio field

similar to note user also have a unique

know medica identifier which is called

user ID or UID for sure and you know

domain is slash user slash one again

that's kind of high to the number

numbers so you can define but IDs s for

users as well so in this case and I

think that promise much people is slash

militia unit the users can also have

language settings so if they speak more

than one language and your website is

available in more than one language they

can decide in which language to use and

if the language that they choose is not

available you can define like a foreign

language the English for example user

can also define time zones and this is

like even in the States

like you know you have at least four

time zones in the continental you know

part of the United States this let's

assume we were streaming it was supposed

to start in every am you know central

time but it is noon Eastern Time

it is nine Pacific time I guess it's

cold so when when you have users they

can define the time zone and if you have

events the dew point will do out of my

types of compression to adapt to each a

specific user for example and let's

let's assume that I want to give you

know Mauricio the permission to add

content to my website how do I do that

how going - clinicians so it's a

combination of two words roles and

permissions our role is a collection of

permissions are we going to see what

permissions are in a moment but roles

are are used to assign privilege to a

group of users they came up

you're higher in organization out of the

box

duper comes with three rows one is the

I'm gonna question you should like if we

go to you know New York Times to come to

read that content only that's like an

anonymous user we don't have an account

like the Facebook or Twitter we just go

to consumer if you have an account that

username and password you become an

authenticated user so with that you can

do things like posting comments for

example but then we also have done

illustrators where I who are able to

like do pretty much anything they want

on the website but it is really hard for

our website to you know be all or

nothing

we also have like middle level

permissions so you can't read your own

permissions like editor so the editor

can modify or not create or the

department chief you know what I

described before you can have put in

addition to whatever one of the books

you can have more roles with a specific

set of permissions and what is the

permission by the way question now can

you get great honors or is you know

having like a end user and be able to

control what content they see based on

roles yes which one you see whether you

can get them for example if you have

another musician you can determine how

much button day they can sue me once

they log in and they can yeah they have

your login and they login I mean they're

that's there they are you know coming to

the website a consumer of the website

bias one control exactly what content

they see based on their login yes so the

way that control content once a user has

to log in is actually through roles so

you create

and you know as I said before they're

rolling alkylation of permissions so for

that row row a you define the things

that they can do like post images post

comments and things like that and

apparition is actually very simple it's

like a yes or no question my permission

is this user based on their role is able

to perform a specific action on the

website and there are literally like

those things if not hundreds of

permissions in Drupal it's really Daniel

so you can say you can create cotton of

that article you can relate variations

you can post comments you can use the

Segway contact form you can view the

price field with with a discount in the

event content type and things like that

you can get like really really granular

and it's a combination of both roles and

permissions and just type in together

this is how the drupal permission system

works if you want to assign Mauricio the

possibility to see that is counted price

for an event how do you do it you don't

have signed permissions directly to

users you do it through roads remember

that a row speculation of users of

permissions and then for that user you

can assign one or more roles and the

user is going to be able to do the sum

of all the roles that they have assigned

a user can have two three roles assigned

and they were going to be able to do you

know there's some of all of those things

and that's in general how how it works

just answer the question and like the

other way is true as well like if you

want to deny access to something you

simply remove the permission of of the

role and then they

have access to them okay uh Northey our

names and maybe this very simple concept

again they are a collection of links use

to navigate the website menus can be

hierarchical so we have two examples

here at the top is like a one level

video it's only like five links and

that's how many the Drupal but you can

have hierarchies like Superman is on

someone's and with modules you can get

really crazy and I don't recommend it to

be honest but just to see the

possibilities down below query using a

model called TB mega menu and with that

you can embed YouTube videos and other

information unknown your name so if you

need to do it for some reason there are

possibilities to do it and the last

concept I'm going to cover today are

taxonomies and to be honest this word

Academy when I first heard it but it's

super simple

taxonomy is just used to classify the

content of your website and by

classification it's like also doing the

connection between them and you only

need to understand two things

vocabularies and trends so a vocabulary

is just a name the steps as a container

so I have double card whatever and

called fruits and it's going to be a

container for terms in this case I have

a term for apple strawberry orange and

grapes so the vocabulary is the mean

container and what terms are the

individual elements inside the

vocabulary and as minier things taxonomy

terms can also have fields so in this

case I associated an image field so that

in addition to displaying that you know

the fruit name I also show an image of

the fruit itself vocabularies can also

be hierarchical so you know living

organism categorization we have kingdom

phylum class you know humans are

supposed to be animal

in the qaddafi loom in the mamada class

on way like 17 level deeps we are almost

uh consultants or something like that so

you can have hierarchical structures for

tax on this as well some real life

example categorization all them all the

next thing that you need although not so

useful real-life examples you can have

when you for example we display an

article you can have other articles

tagged with one specific turn and you

start as like related content for

example and there are also models that

extend this taxonomy system so you can

show for example access controls based

on taxonomy so there is a model called

word play access that ties the

permission system with the taxonomy

system if you need it in Drupal 7 there

was a model location personalize that

for a specific ten you are able to

associate the Oracle information so for

example if we talk something like

Chicago what ye Boston and so on then

just by tagging that you can use

geological information to display

pointers on among the module is no

longer needed in Drupal 8 because the

Drupal 8 taxonomy can have things out of

the box it wasn't a case into for seven

but you can accomplish similar

functionality finally super important to

understand the concept because you will

interact with all of them when reading a

page and in fact like for one page you

can enter 200 of all these things at the

same time an FAQ that to be honest no

one else and you get it myself and it is

like there is a sailing into folder

every time that you have poor God kills

aquiline please think of the kidney and

the word heart in this case again it is

overloaded it is not what we hear in the

news like some hacker

came to my website and

you know asked me for a ransom in Drupal

but we still had we mean modifying the

code that we get from the father or if

you change one line one semicolon

anything that you change that is

consider having the Drupal and that's

bad because you know you can modify how

the system works in very weird ways most

importantly you can modify for example

of how the access control system works

and you can be granting access to people

that should have it so please do not

modify or hack or you know what you're

doing because there are some benefits

for that but in general they do it so if

you're not supposed to modify core but

you have a specific need

where are you supposed to do you use die

yeah I remember that Drupal is a

framework you use the API and to learn

more about that you can check out this

session

it's likes are available if you want to

learn what about theming and how the

Drupal you know presentation later works

you can see that session that I also

presented and I highly highly recommend

to get involved with the community

because you will get your question

answered by way way faster thank you

very much I would really like to you

know to have your kid so I know that

we're over ten already so there are no

questions otherwise I would be around

beautiful campus
