Symfony 5(包括4)使用Gedmo Doctrine扩展SoftDelete

Question

我尝试使用软删除(使用gedmo/doctrine-extensions)在Symfony 5中的一些实体，并得到了一些麻烦:

侦听器"SoftDeleteableListener"未添加到EventManager!

编译错误:AppEntityAdmin和GedmoSoftDeleteableTraitsSoftDeleteableEntity在AppEntityAdmin的组成中定义了相同的属性($deletedAt)。然而，定义不同，被认为是不相容的。类组成

这是我试过的，它运行良好

1. 安装gedmo/doctrine-extensions

   composer require gedmo/doctrine-extensions
   

2. 添加列deleted_at到表中你想使用软删除(使用迁移或手动添加)

3. 添加config到config/packages/doctrine.yaml

   filters:
   softdeleteable:
   class: GedmoSoftDeleteableFilterSoftDeleteableFilter
   enabled: true
   

4. 添加config到config/services。yaml

   gedmo.listener.softdeleteable:
   class: GedmoSoftDeleteableSoftDeleteableListener
   tags:
   - { name: doctrine.event_subscriber, connection: default }
   calls:
   - [ setAnnotationReader, [ '@annotation_reader' ] ]
   

5. 添加Gedmo并使用SoftDeleteableEntity到您的实体

   <?php
   namespace AppEntity;
   use GedmoSoftDeleteableTraitsSoftDeleteableEntity;
   /**
   * @ORMEntity(repositoryClass=AdminRepository::class)
   * @ORMTable(name="admins")
   * @GedmoSoftDeleteable(fieldName="deletedAt", timeAware=false, 
   hardDelete=false)
   */
   class Admin implements UserInterface
   {
   use SoftDeleteableEntity;
   ….
   }
   

6. 最后，像往常一样使用delete函数，deleted_at列将被更新

   /**
   * @param Admin $admin
   */
   public function delete(Admin $admin)
   {
   $this->_em->remove($admin);
   $this->_em->flush();
   }
   

注意：不需要添加deletedAt字段，方法getDeletedAt和setDeletedAt到您的实体

Answer 1

如果您使用PHP格式(config/services.php)而不是YAML，请将步骤4更改为以下内容。

$services->set("gedmo.listener.softdeleteable")
->class(GedmoSoftDeleteableSoftDeleteableListener::class)
->tag(name: 'doctrine.event_subscriber', attributes: ["method" => "setAnnotationReader", "connection" => "default"])
->args([service('doctrine.orm.metadata.annotation_reader')])
;
