Question

Symfony2相当新鲜;我现在使用FOSUserBundle作为我的userprovider。由于它没有为删除操作提供控制器，我自己写了：

    /**
         * Delete user
         *
         * @param integer $id
         *
         * @Route("/delete/{id}")
         *
         * @return RedirectResponse
         */

        public function deleteAction($id)
        {
            $em = $this->getDoctrine()->getManager();
            $um = $this->get('fos_user.user_manager');

            $user = $um->findUserBy(array(
                'id' => $id
                )
            );

            $em->remove($user);
            $em->flush();

           return new RedirectResponse("star9988_user_user_index");
        }

并在我的模板中添加了指向路径的链接：

    <a href="{{ path('star9988_user_user_delete', {'id': user.id}) }}">

我最初尝试传递ObjectManager，按ID查询User对象，然后使用deleteUser方法删除它，但由于某种原因，它不会让我使用通常的构造函数注入来获取ObjectManager方法

结果，我已经调用了EntityManager，并在我的$ user对象上调用了remove（）方法。

结果很奇怪：当我用SequelPro检查我的数据库时，我注意到确实删除了指定的用户对象。但是，浏览器会返回此错误：

EntityManager #remove（）期望参数1是实体对象，给出NULL。

非常感谢任何帮助。

编辑：

I have changed my code to the following:

    /**
     * Delete user
     *
     * @param integer $id
     *
     * @Route("/delete/{id}")
     *
     * @return RedirectResponse
     */

    public function deleteAction($id)
    {
        $em = $this->getDoctrine()->getManager();

        /** @var \Star9988\ModelBundle\Entity\User $user */
        $user = $this->getDoctrine()->getRepository('ModelBundle:User')->find($id);

        $em->remove($user);
        $em->flush();

       return new RedirectResponse("star9988_user_user_index");
    }

奇怪的是，我得到了相同的结果：实体从数据库中删除。

由于某种原因，我的路线似乎没有传递参数。

DEBUG - SELECT t0.username AS username1，t0.username_canonical AS username_canonical2，t0.email AS email3，t0.email_canonical AS email_canonical4，t0.enabled AS enabled5，t0.salt AS salt6， t0.password AS password7，t0.last_login AS last_login8，t0.locked AS locked9，t0.expired AS expired10，t0.expires_at AS expires_at11， t0.confirmation_token AS confirmation_token12， t0.password_requested_at AS password_requested_at13，t0.roles AS roles14，t0.credentials_expired AS credentials_expired15， t0.credentials_expire_at AS credentials_expire_at16，t0.id AS id17， t0.FirstName AS FirstName18，t0.LastName AS LastName19，t0.creditLimit AS creditLimit20，t0.creditAvailable AS creditAvailable21， t0.accountBalance AS accountBalance22，t0.rebate AS rebate23， t0.parent AS parent24 FROM StarUsers t0 WHERE t0.id =？限制1

Answer 1

尝试将ID设置为必需参数，例如this example：

/**
 * @Route("
 *    path          = "/delete/article/{id}", 
 *    name          = "blog_admin_delete_article"
 *    requirements  = { "id" = "\d+" },
 *    methods       = { "GET" }
 * )
 */
public function deleteArticleAction($id) { /* ... */ }

您还可以检查用户加载的代码：

    /** @var \Star9988\ModelBundle\Entity\User $user */
    $user = $this->getDoctrine()->getRepository('ModelBundle:User')->find($id);
    if (!$user instanceof User) {
        throw new NotFoundHttpException('User not found for id ' . $id);
    }

我希望它有所帮助。

Answer 2

获得用户经理时

$um = $this->container->get('fos_user.user_manager')

您可以在获取用户操作后使用删除操作：

$um->deleteUser($user);

但您需要先检查用户是否为空。
