***************Doctrine, Symfony & the Database***************
Database

-setup a database with doctrine
symfony console list doctrin
composer require symfony/ore-pack
composer require --dev symfony/maker-bundle

-inside .env
DATABASE_URL="mysql://root:admin@127.0.0.1:3306/movies?serverVersion=5.7&charset=utf8mb4"
symfony console doctrine:database:create
symfony console doctrine:database:drop

-or user docker
./bin/console make:docker:database
 Next:
  A) Run docker-compose up -d database to start your database container
     or docker-compose up -d to start all of them.
	 docker-compose down  drop and destroy container 
	
 
  B) If you are using the Symfony Binary, it will detect the new service automatically.
     Run symfony var:export --multiline to see the environment variables the binary is exposing.
     These will override any values you have in your .env files.
 
  C) Run docker-compose stop will stop all the containers in docker-compose.yaml.
     docker-compose down will stop and destroy the containers.

-docker-compose & Exposed Ports
Docker-compose
Docker-compose ps         :     show all containers cuz the ports change every time
Docker-compose exec database mysql -u root -password:password        : install mysql inside container
Mysql -u root --password:password --host=127.0.0.1 --port=50769	  : connect to database
 -> SHOW DATABASES;
 -> CREATE DATABASE docker_coolness;

-docker-compose Env Vars & Symfony
Symfony serve -d
Symfony var:export --multiline        : show all infos about database


-doctrine:database:create & server_version

-Entity Class: corresponding php class
-create an entity

-Persisting to the Database
EntityManagerInterface
     $em->persist($question);
     $em->flush();
Symfony console doctrine:query:sql 'SELECT * FROM question'

-Fetching Data & The Repository
$repository = $em->getRepository(Question::class);
$question = $repository->findOneBy(['slug' => $slug]);

-Entity objects in Twig

-"5 Minutes Ago" Strings		: |ago
Composer require knplabs/knp-time-bundle

-Custom Repository Class
$questions = $repository->findBy([], ['askedAt' => 'DESC']);
Inside the repo order u can write ur own queris
findAllAskedOrderedByNewest()

-DQL & The Query Builder
https://symfonycasts.com/screencast/doctrine-queries

-Reusing Query Logic & Param Converters
Inside the repo order:	2 private functions

-Automatic Controller Queries: Param Converter
Not using the $repo instate of that we use the Entity 

-Smarter Entity Methods
symfony console make:entity Question
Votes

-Request Object & POST Data
As controller arguments(variables)
 - name as $slug
 - service as LoggerInterface
 - Entity as Question for Query
 - Request 

-Update Query & Rich vs Anemic Models
Vote in database updaten and redirect the page

-dummy data through Data Fixtures
composer require --dev doctrine/doctrine-fixtures-bundle
-load data fixtures to database

*****************Mastering Doctrine Relations*****************

-The Answer Entity
symfony console make:entity
Symfony console make:migration
symfony console doctrine:migrations:migrate

-The ManyToOne Relation
Each answer has one question and each question has many answers -> Answer field has question_id in database
symfony console make:entity Answer
	-question
	-relation
	-Question
	-ManyToOne
	-no
	-yes
	-answers
	-no

 ------------ ---------------------------------------------------------------------- 
  Type         Description                                                           
 ------------ ---------------------------------------------------------------------- 
  ManyToOne    Each Answer relates to (has) one Question.                            
               Each Question can relate to (can have) many Answer objects

               Each Question can also relate to (can also have) many Answer objects  
                                                                                     
  OneToOne     Each Answer relates to (has) exactly one Question.                    
               Each Question also relates to (has) exactly one Answer.               
 ------------ ---------------------------------------------------------------------- 

-Saving Relations
 $answer->setQuestion($question);

-Relations in Foundry	:	create answers to random questions in database
Symfony console make:factory

-Foundry: Always Pass a Factory Instance to a Relation
Symfony console doctrine:query:sql 'SELECT DISTINCT(question_id) FROM answer'
Using unpublished method in appfixtuers und in answerfaktory

-Fetching Relations
Just in Controller

-Rendering Answer Data & Saving Votes
In controller and twig
Here we can render the answers for the question in the twig by calling question.answers

-Owning Vs Inverse Sides of a Relation

-Relation OrderBy & fetch=EXTRA_LAZY
In eintity

-Filtering to Return only Approved Answers

-Joining Across a Relationship & The N + 1 Problem

https://medium.com/doctolib/understanding-and-fixing-n-1-query-30623109fe89
For more query performence	-> makes the getmostpopluar in one Query so goooood.

-Search, the Request Object & OR Query Logic
Really nice one in most popular make search for answers and questions
elasticsearch for smarter search

-The 4 (2?) Possible Relation Types
ManyToOne, OneToMany, OneToOne -> are really the same realstionship
ManyToMany -> its deferent lest make one here. By doing Tags
OneToOne -> USER, Profile: in one class to reduce the complexity
		-> wait until you have real performance problems and then debug it.
symfony console make:entity
	- Tag
	- name
	- string
	- 255
	- no
	-taggedAt
	-dateTime-im
	-no
Symfony console make:migration
symfony console doctrine:migrations:migrate

-ManyToMany Relation
Each Tag has many questions and each Question has many Tags.  No deferents where:
symfony console make:entity
	-Question
	-tags
	-relation
	-Tag
	-ManyToMany
	-yes
	-questions

-Saving Items in a ManyToMany Relation
In Appfixtuers

-Handling ManyToMany in Foundry
Symfony console make:factory
	-Tag

-Joining Across a ManyToMany : fixing N + 1 Problem
To get les querys and more performance HOW:
Like how we did to answers in AnswerRepo by joining across the question relationship and then selecting the question data.


-ManyToMany... with Extra Fields on the Join Table?	
As soon we need one extra column on this manytomany, we need to stop using a ManytoMany relationship instead we need to create an Entity for the join table and manually relate the entity to question and tag. So the entity QuestionTag
But I will not use it so I will use the manytomany
-When a Migration Falls Apart
-QuestionTag Fixtures & DateTimeImmutable with Faker
Here I do not use QuestionTag I use the old manytomany Tag
-Doing Crazy things with Foundry & Fixtures
-JOINing Across Multiple Relationships

-Pagination with Pagerfanta
To make see more questions -> doctrine features -> KnpPagiator, Pagerfanta
When we use it so we do not need to query the data directly instead, our job to create a querybuilder and pass that to the pagerinator-> which will then figure out which page we are on, set up the limit and offset parts of the query and then execute it.
https://github.com/BabDev/PagerfantaBundle
composer require babdev/pagerfanta-bundle
composer require pagerfanta/doctrine-orm-adapter

-Themed Pagination Links
