Api 平台：实体级联上的订单

Question

有了Api平台，我们可以联合下单

Documentation :

use ApiPlatform\Core\Annotation\ApiResource;

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

但我想在实体级联上排序。

对于下面的例子，我用这个错误进行了测试：

 * @ApiResource(
 *     attributes={
 *         "order"={"exercises.repetitions.id":"asc"}
 *     }
 * )

[Semantical Error] line 0, col 422 near 'id ASC, rests_a6.id': Error: Class App\Entity\TrainingSerieExercise has no field or association named repetitions.id

TrainingSerie实体：

 * @ApiResource(
       ...
 *     attributes={
 *         "order"={"exercises.repetitions.id":"asc"}
 *     }
 * )
 */
class TrainingSerie
{
    ...

    /**
     * @var TrainingSerieExercise[]|ArrayCollection
     *
     * @ORM\OneToMany(
     *     targetEntity="App\Entity\TrainingSerieExercise",
     *     mappedBy="serie",
     *     cascade={"persist"}
     * )
     * @Groups({
     *     "trainings_read",
     *     "training_series_read",
     *     "training_series_write",
     * })
     */
    private $exercises;

...

TrainingSerieExercise实体：

...
class TrainingSerieExercise
{
    ...
    /**
     * @var TrainingSerieRepetition[]|ArrayCollection
     *
     * @ORM\OneToMany(
     *     targetEntity="App\Entity\TrainingSerieExerciseRepetition",
     *     mappedBy="exercise",
     *     cascade={"persist"},
     * )
     * @Groups({
     *     "training_series_read",
     *     "training_series_write",
     *     "training_serie_exercices_write",
     * })
     */
    private $repetitions;
    ...

TrainingSerieExerciseRepetition实体：

class TrainingSerieExerciseRepetition
{
    ...
    /**
     * @var integer
     *
     * @ORM\Id
     * @ORM\Column(name="id", type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     * @Groups({
     *     "training_series_read",
     * })
     */
    private $id;
    ...

Answer 1

在此之后 Doctrine doc 这将按 id:

排序 TrainingSerieExercise::$repetitions

class TrainingSerieExercise
{
    ...
    /**
     * @var TrainingSerieRepetition[]|ArrayCollection
     *
     * @ORM\OneToMany(
     *     targetEntity="App\Entity\TrainingSerieExerciseRepetition",
     *     mappedBy="exercise",
     *     cascade={"persist"},
     * )
     * @ORM\OrderBy({"id" = "ASC"})
     * @Groups({
     *     "training_series_read",
     *     "training_series_write",
     *     "training_serie_exercices_write",
     * })
     */
    private $repetitions;
    ...
