Overriding Default Order

API Platform Core provides an easy way to override the default order of items in your collection.

By default, items in the collection are ordered in ascending (ASC) order by their resource identifier(s). If you want to customize this order, you must add an order attribute on your ApiResource annotation:

<?php
// api/src/Entity/Book.php

namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;

/**
 * @ApiResource(attributes={"order"={"foo": "ASC"}})
 */
class Book
{
    // ...

    /**
     * ...
     */
    public $foo;
}

This order attribute is used as an array: the key defines the order field, the values defines the direction. If you only specify the key, ASC direction will be used as default. For example, to order by foo & bar:

<?php
// api/src/Entity/Book.php

namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;

/**
 * @ApiResource(attributes={"order"={"foo", "bar"}})
 */
class Book
{
    // ...

    /**
     * ...
     */
    public $foo;

    /**
     * ...
     */
    public $bar;
}

It's also possible to configure the default order on an association property:

<?php
// api/src/Entity/Book.php

namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;

/**
 * @ApiResource(attributes={"order"={"author.username"}})
 */
class Book
{
    // ...

    /**
     * @var User
     */
    public $author;
}
