Symfony ApiPlattform-映射与AliceDataFixtures: ManyToMany问题

Question

我在使用symfony设置api平台项目和使用hautelook/alice-bundle加载固定装置时遇到了一些问题。

提供了以下实体：

// ./src/Entity/UserGroup.php

#[ApiResource(
    collectionOperations: [
        'get' => [
            'normalization_context' => [
                'groups' => [
                    'userGroup:collection:get',
                    'item:collection:get',
                ],
            ],
        ],
        'post' => [
            'normalization_context' => [
                'groups' => [
                    'userGroup:collection:post',
                    'item:collection:get',
                ],
            ],
            'denormalization_context' => [
                'groups' => [
                    'userGroup:collection:post',
                ],
            ],
        ],
    ],
    itemOperations: [
        'get' => [
            'normalization_context' => [
                'groups' => [
                    'userGroup:item:get',
                    'item:get',
                ],
            ],
        ],
        'put' => [
            'normalization_context' => [
                'groups' => [
                    'userGroup:item:get',
                    'item:get',
                ],
            ],
            'denormalization_context' => [
                'groups' => [
                    'userGroup:item:put',
                ],
            ],
        ]
    ]
)]
#[ORM\Entity]
class UserGroup
{
    #[ORM\Column(type: Types::STRING, length: 128)]
    #[Assert\NotBlank]
    #[Assert\Length(min: 2, max: 128)]
    #[Groups([
        "userGroup:item:get",
        "userGroup:collection:get",
        "userGroup:collection:post",
        "userGroup:item:put",
    ])]
    protected string $name;

    // ID, other attributes, name getter and setter, ...
}

./src/Entity/User.php
#[ApiResource(
    collectionOperations: [
        'get' => [
            'normalization_context' => [
                'groups' => [
                    'user:collection:get',
                    'item:collection:get',
                ],
            ],
        ],
        'post' => [
            'normalization_context' => [
                'groups' => [
                    'user:collection:post',
                    'item:collection:get',
                ],
            ],
            'denormalization_context' => [
                'groups' => [
                    'user:collection:post',
                ],
            ],
        ],
    ],
    itemOperations: [
        'get' => [
            'normalization_context' => [
                'groups' => [
                    'user:item:get',
                    'item:get',
                ],
            ],
        ],
        'put' => [
            'normalization_context' => [
                'groups' => [
                    'user:item:get',
                    'item:get',
                ],
            ],
            'denormalization_context' => [
                'groups' => [
                    'user:item:put',
                ],
            ],
        ]
    ]
)]
#[ORM\Entity]
class User
{
    #[ORM\ManyToMany(targetEntity: UserGroup::class)]
    #[Groups([
        'userReal:item:get',
        'userReal:collection:post',
        'userReal:item:put'
    ])]
    protected $userGroups;

/**
     * @param mixed $userGroups
     */
    public function setUserGroups($userGroups): void
    {
        $this->userGroups = $userGroups;
    }

    // ID, other attributes, name getter and setter, ...
}

夹具文件包含以下数据：

App\Entity\UserGroup:
  userGroup_admin:
    name: 'Administrator'
    active: true
App\Entity\User:
  admin:
    email: 'admin@domain.tld'
    userGroups: [
        '@userGroup_admin'
    ]

运行命令"php /console hautelook:bin:load“将显示以下错误：

Fidry\AliceDataFixtures\Bridge\Doctrine\Persister\ObjectManagerPersister::getMetadata(): Argument #2 (  
  $object) must be of type object, array given, called in [...]/vendor/theofidry/alice-data-fixtures/src/Bridge/Doctrine/Persister/ObjectManagerPersister.php o  
  n line 158                                   

如果在用户类中添加"addUserGroup“和"removeUserGroup”并删除UserGroup的getter和setter，则该命令将按预期运行。这个修复之后，问题就出现在ApiPlatform请求处理中:如果一个实体有两个UserGroups，并且PUT请求(实体的完全更新)发送其他UserGroups，那么旧的UserGroups仍然存在(当然，只会导致add-方法存在，而不是完全setter)。

有什么办法解决这个问题吗？

// composer.json 
{
"api-platform/core": "^2.6",
"hautelook/alice-bundle": "^2.9",
"symfony/*": "5.4.*",
}

您可以考虑修改您的User::setUserGroups()方法，如下所示：

// be sure to import the ArrayCollection
use Doctrine\Common\Collections\ArrayCollection;

/**
 * @param array $userGroups
 */
public function setUserGroups(array $userGroups): void
{
    $this->userGroups = new ArrayCollection($userGroups);
}

在设置$userGroups时，错误可能是一个类型问题。您正在发送一个数组(在夹具中使用[] )，属性是一个ManyToMany，它通常是一个Collection。

在进行此操作之前，您应该检查代码库的其余部分，并确保它不会破坏其他内容。
