Symfony：如何对实体的One2Many / Many2One进行排序？

Question

I've three entities: Product , ProductPicture and Picture .

I'd like to sort the pictures by it's position and tried this , code below.

Result : it's not sorting the joined pictures by position. It's sorting the products by the pictures' position.

I'm confused. As far as I can see, I followed the docs, but get a weird result. Cache was cleared.

Any ideas? Thanks in advance!

Entity: Product

// ...
class Product {
    /**
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue
     */
    protected $id;


    /**
     * @ORM\OneToMany(targetEntity="ProductPicture", mappedBy="product")
     * @ORM\OrderBy({"position" = "DESC"})    // <------ !!!
     */
    protected $pictures;

    // ...
}

Entity: ProductPicture

// ...
class ProductPicture {
    /**
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue
     */
    protected $id;


    /**
     * @ORM\Column(type="integer")
     */
    protected $position;


    /**
     * @ORM\ManyToOne(targetEntity="Product", inversedBy="pictures")
     * @ORM\JoinColumn(name="product_id", referencedColumnName="id")
     */
    protected $product;


    /**
     * @ORM\ManyToOne(targetEntity="Picture")
     * @ORM\JoinColumn(name="picture_id", referencedColumnName="id")
     */
    protected $picture;

    // ...
}

Entity: Picture

// ...
class Picture {
    /**
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue
     */
    protected $id;


    /**
     * @ORM\Column(name="path", type="string")
     */
    protected $path;

    // ...
}

The docs are right:

<?php
/** @Entity **/
class User
{
    // ...

    /**
     * @ManyToMany(targetEntity="Group")
     * @OrderBy({"name" = "ASC"})
     **/
    private $groups;
}

In my case the findAll() -method of the repository was overwritten which led to this mess. Make sure, your customized queries are not in conflict with the doctrine defaults, if you've the same issue. :-)
