Question

在我的课堂上，我对＆＃34;用户＆＃34;有一个UniqueEntity限制。字段（最初是＆＃34; user＆＃34;和＃34; name＆＃34;的组合），它来自fosuserbundle，如果我将约束放在＆＃34; name＆＃34;例如，约束完成它的工作，我得到一个错误，说它不是唯一的。这不会发生在用户字段上，但是，我没有收到任何错误，并且实体已添加到我的数据库中。有人可以指出我犯的错误吗？

好的，我发现了我的错误，它在我的控制器逻辑中：

...
        $list = new CustomList();

        $form = $this->createForm(new CustomListType(), $list);
        $form->submit($request);
        $list = $form->getData();


        $validator = $this->get('validator');           
        $errors = $validator->validate($list);

        var_dump((string) $errors);

        if ($form->isValid()){


             $em = $this->getDoctrine()->getManager();

            //set current user as user-value of this list
            $list->setUser($this->getUser());

            $em->persist($list);
            $em->flush();

            //prepare the response, e.g.
            $response = array("code" => 100, "success" => true);
            //you can return result as JSON  , remember to 'use' Response!
            return new Response(json_encode($response));  
       ...

正如您所看到的，我在表单验证后设置了用户，这意味着它总是会验证空值，如下面的文档中所示：UniqueEntity ignoreNull的默认值为true，这意味着它会总是通过测试。

移动$ list-＆gt; setUser（$ this-＆gt; getUser（））;在我验证表单之前修改了这个问题！

fosuserbundle字段上的UniqueEntity不起作用
