Question

我的动机是编辑此编辑表单中显示的值。但是，当我按下编辑按钮时，它会抛出此错误。我无法弄清楚。任何人都可以帮助我的代码中缺少什么吗？

在渲染模板期间抛出了异常（“Some 缺少必需参数（“user”）以生成路由的URL “sokosimu_editor_edit_editoruser”。“）in SokosimuEditorBundle：用户：第7行的editUser.html.twig。500内部服务器错误 - Twig_Error_Runtime

路由器

sokosimu_editor_edit_editoruser:
    path: /edit/editoruser/{user}
    defaults: {_controller:SokosimuEditorBundle:Editor:editEditorUser}
    requirements:
            _method:  GET|POST

控制器

    public function editEditorUserAction(User $user,Request $request){

    $form = $this->createForm(new EditUserType(),$user);

    //2. handle the submit (will happen on POST)
    $form->handleRequest($request);
    if($form ->isValid() && $form->isSubmitted()){
    }
    $em = $this->get('doctrine')->getManager();

    $editUser = $user ->getEditoruser();
    return $this->render('SokosimuEditorBundle:User:editUser.html.twig', array(
        'form' => $form->createView()
    ));

}

 {% block title %}Edit User{% endblock%}

 {% block body %}

<form action="{{ path('sokosimu_editor_edit_editoruser') }}" method="post" {{ form_enctype(form) }} class="formedit">

Answer 1

您需要在路径中传递用户：

<form action="{{ path('sokosimu_editor_edit_editoruser', {'user': user}) }}" method="post" {{ form_enctype(form) }} class="formedit">

在控制器中用用户渲染树枝：

return $this->render('SokosimuEditorBundle:User:editUser.html.twig', array(
    'form' => $form->createView(),
    'user' => $user
));

修复路线

sokosimu_editor_edit_editoruser:
    path: /edit/editoruser/{userId}
    defaults: {_controller:SokosimuEditorBundle:Editor:editEditorUser}
    requirements:
        _method:  GET|POST

将控制器修复为

public function editEditorUserAction(Request $request, $userId)
{
    $user = $this->getDoctrine()->getRepository('SokosimuEditorBundle:User')->find($userId);
    $form = $this->createForm(new EditUserType(), $user);

    //2. handle the submit (will happen on POST)
    $form->handleRequest($request);

    if ($form->isValid() && $form->isSubmitted()) {
        $em = $this->get('doctrine')->getManager();

        $editUser = $user->getEditoruser();
    }

    return $this->render('SokosimuEditorBundle:User:editUser.html.twig', array(
        'form' => $form->createView()
    ));
}

Answer 3

在@ panche14的帮助下，我对代码进行了一些修改。来自@ panche14的答案返回了对象，但@param形式应该是字符串或整数。

return $this->render('SokosimuEditorBundle:User:editUser.html.twig', array('form' => $form->createView(), 'user' => $user ->getId(); ));

还要在twig文件中添加：

{＆＃39;用户＆＃39;：用户}

由@ panche14

指定

现在，编辑按钮可以正常工作。

缺少一些必需参数（“用户”）来生成路由的URL
