# ORM

# Doctrine

Doctrine is the ORM used, you have at your disposal the entities in the folder app/src/Entity and access to EntityManager from the controllers with $this->em;.

Here is the doctrine command that you will need to declare your entities in database (Make sure you have created your database beforehand):

Linux and MacOs

$ php vendor/bin/doctrine orm:schema-tool:update

Windows

$ php vendor/doctrine/orm/bin/doctrine.php orm:schema-tool:update

Beside your entities you have repository, these are the classes where you will write the doctrine queries using for example its QueryBuilder.

For more info on the ORM, I invite you to go and see the documentation officiel.

# Fixtures

You can send predefined database data with data-fixtures, create your fixtures in the app/src/Entity/DataFixtures folder, and run the command :

$ php console data:fixtures

Attention, this command purges the database to then send all the fixtures of file app/src/Entity/DataFixtures, to send a specific fixture without hollowing the base, to launch the command :

$ php console data:fixture <YourFixture>
