Orbitale Doctrine Tools

This library is composed of multiple tools to be used with the Doctrine ORM.

Documentation

Installation

Simply install the library with Composer:

    composer require orbitale/doctrine-tools:~0.1

Usage

Entity Repository

There are 3 ways of using EntityRepositoryHelperTrait:

  1. In your own repositories, just extend the Orbitale's one:
<?php

namespace AppBundle\Repository;

use Orbitale\Component\DoctrineTools\EntityRepositoryHelperTrait;

class PostRepository
{
    use EntityRepositoryHelperTrait;

    // Your custom logic here ...

}
  1. If you are using Symfony, you can override the default entity manager in the configuration:
# app/config.yml
doctrine:
    orm:
        default_repository_class: Orbitale\Component\DoctrineTools\EntityRepositoryHelperTrait
  1. If you are using Doctrine "natively", you can override the default entity repository class in the Doctrine Configuration class:
$configuration = new Doctrine\ORM\Configuration();
$configuration->setDefaultRepositoryClassName('Orbitale\Component\DoctrineTools\EntityRepositoryHelperTrait');

// Build the EntityManager with its configuration...

This way, you can use your EntityRepository exactly like before, it just adds new cool methods!

Just take a look at the EntityRepositoryHelperTrait class to see what nice features it adds!

Doctrine Fixtures

This class is used mostly when you have to create Doctrine Fixtures, and when you want the most simple way to do it.

To use it, you must install doctrine/data-fixtures (and doctrine/doctrine-fixtures-bundle if you are using Symfony).

Here is a small example of a new fixtures class:

<?php

namespace AppBundle\DataFixtures\ORM;

use App\Entity\Post;
use Orbitale\Component\DoctrineTools\AbstractFixture;
use Doctrine\Bundle\FixturesBundle\ORMFixtureInterface;

class PostFixtures extends AbstractFixture implements ORMFixtureInterface
{
    public function getEntityClass(): string
    {
        return Post::class;
    }

    public function getObjects(): array
    {
        return [
            ['title' => 'First post', 'description' => 'Lorem ipsum'],
            ['title' => 'Second post', 'description' => 'muspi meroL'],
        ];
    }
}

Using a callable to get a reference

When you have self-referencing relationships, you may need a reference of an object that may have already been persisted.

For this, first, you should set the flushEveryXIterations option to 1 (view below) to allow flushing on every iteration.

And next, you can set a callable element as the value of your object so you can interact manually with the injected object as 1st argument, and the AbstractFixture object as 2nd argument.

The EntityManagerInterface is also injected as 3rd argument in case you need to do some specific requests or query through another table.

Example here:

<?php

namespace App\DataFixtures\ORM;

use App\Entity\Post;
use Orbitale\Component\DoctrineTools\AbstractFixture;
use Doctrine\Bundle\FixturesBundle\ORMFixtureInterface;
use Doctrine\ORM\EntityManagerInterface;

class PostFixtures extends AbstractFixture implements ORMFixtureInterface
{
    public function getEntityClass(): string
    {
        return Post::class;
    }

    /**
     * With this, we can retrieve a Post reference with this method:
     * $this->getReference('posts-1');
     * where '1' is the post id.
     * Only works with same object if it's flushed on every iteration.
     */
    public function getReferencePrefix(): ?string
    {
        return 'posts-';
    }

    /**
     * Set this to 1 so the first post is always persisted before the next one.
     * This is mandatory as we are referencing the same object. 
     * If we had to use a reference to another object, only "getOrder()" would have to be overriden. 
     */
    public function flushEveryXIterations(): int 
    {
        return 1;
    }

    public function getObjects(): array
    {
        return [
            ['id' => 'c5022243-343b-40c3-8c88-09c1a76faf78', 'title' => 'First post', 'parent' => null],
            [
                'title' => 'Second post',
                'parent' => function(Post $object, AbstractFixture $fixture, EntityManagerInterface $manager) {
                    return $fixture->getReference('posts-c5022243-343b-40c3-8c88-09c1a76faf78');
                },
            ],
        ];
    }
}

This allows perfect synchronicity when dealing with self-referencing relations.

Methods of the AbstractFixture class that can be overriden:

  • getOrder() (default 0) to change the order in which the fixtures will be loaded.
  • getReferencePrefix() (default null) to add a reference in the Fixtures' batch so you can use them later. References are stored as {referencePrefix}-{id|__toString()}.
  • getMethodNameForReference() (default getId) to specify which method on the object is used to specify the reference. Defaults to getId and always falls back to __toString() if exists.
  • flushEveryXIterations() (default 0) to flush in batches instead of flushing only once at the end of all fixtures persist.
  • disableLogger() to disable SQL queries logging, useful to save memory at runtime.

This way, 2 objects are automatically persisted in the database, and they're all identified with their ID. Also, if you run the symfony app/console doctrine:fixtures:load using the --append option, the IDs will be detected in the database and will not be inserted twice, with no error so you can really use fixtures as reference datas!

Take a look at the AbstractFixture class to see what other methods you can override!
