Converting Doctrine Relational Annotations to YML Configuration

PHP
1

Progressing through the Symfony 2 documentation I have hit a snag. In most sections where yml, annotations/php or xml can be used the alternatives are provided. In most cases these are interchangeable. However, in regards to Doctrine only one can be used per bundle, I believe. I have choosen to use yml. However, the below information in the docs only shows how to get relational mappings hooked up using annotations which will not work because it one or the other and I am using yml. I would appreciate it if someone could tell mm how to convert the annotations below to doctrine yml.


// src/Acme/StoreBundle/Entity/Category.php
// ...
use Doctrine\\Common\\Collections\\ArrayCollection;

class Category
{
    // ...

    /**
     * @ORM\\OneToMany(targetEntity="Product", mappedBy="category")
     */
    protected $products;

    public function __construct()
    {
        $this->products = new ArrayCollection();
    }
}



// src/Acme/StoreBundle/Entity/Product.php
// ...

class Product
{
    // ...

    /**
     * @ORM\\ManyToOne(targetEntity="Category", inversedBy="products")
     * @ORM\\JoinColumn(name="category_id", referencedColumnName="id")
     */
    protected $category;
}

This section is the part this is all outlined in the Symfony 2 docs:

Symfony - Databases and Doctrine (“The Model”)

This is my current yml configuration for the Product and Category entity.

Category.orm.yml


Acme\\StoreBundle\\Entity\\Category:
  type: entity
  table: category
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
    name:
      type: string
      length: '255'
  lifecycleCallbacks: {  }

Product.orm.yml


Acme\\StoreBundle\\Entity\\Product:
    type: entity
    repositoryClass: Acme\\StoreBundle\\Repository\\ProductRepository
    table: product
    id:
        id:
            type: integer
            generator: { strategy: AUTO }
    fields:
        name:
            type: string
            length: 100
        price:
            type: decimal
            scale: 2
        description:
            type: text

I had to dig around the doctrine docs a little but finally figured it out:

Product.orm.yaml


Acme\\StoreBundle\\Entity\\Product:
    type: entity
    repositoryClass: Acme\\StoreBundle\\Repository\\ProductRepository
    table: product
    id:
        id:
            type: integer
            generator: { strategy: AUTO }
    fields:
        name:
            type: string
            length: 100
        price:
            type: decimal
            scale: 2
        description:
            type: text
    manyToOne:
        category:
            targetEntity: Category
            mappedBy: product

Category.orm.yaml


Acme\\StoreBundle\\Entity\\Category:
  type: entity
  table: category
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
    name:
      type: string
      length: '255'
  lifecycleCallbacks: {  }
  oneToMany:
    products:
      targetEntity: Product
      mappedBy: category
