mysql - Laravel 4 - 找不到 Controller

Question

我正在使用 laravel 开发一个应用程序，它将文件保存在数据库和目标文件夹中。我试图从数据库中删除一条记录，但我得到的只是一个错误，表明找不到 Controller 方法。

错误:

Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException
Controller method not found.

throw new NotFoundHttpException("Controller method not found.");

View alluploads.blade.php 有一个表单，它应该将 id 传递给上传/销毁函数。

{{ Form::open(array('method' => 'DELETE', 'url' => array('uploads/destroy', $upload->id))) }}
     {{ Form::submit('Delete', array('class' => 'btn btn-danger')) }}
{{ Form::close() }}

我的 Controller 有删除行的功能。

public function getDestroy($id)
{
     $this->upload->find($id)->delete();
     return Redirect::to('uploads/alluploads')->with('message', 'Thanks, delete was successful!');
}

路由具有以下访问上传 Controller 下的功能

Route::controller('uploads', 'UploadsController');

Answer 1

您正在使用 HTTP 方法 DELETE，因此您的 Controller 方法应该是:

public function deleteDestroy($id)
{
     $this->upload->find($id)->delete();
     return Redirect::to('uploads/alluploads')->with('message', 'Thanks, delete was successful!');
}

看看你的路线:

php artisan routes

至少，你必须在那里看到这样的东西:

+--------+---------------------------------------------------------------+----------------------+-------------------------------------------------------+--------------------------------+---------------+
| Domain | URI                                                           | Name                 | Action                                                | Before Filters                 | After Filters |
+--------+---------------------------------------------------------------+----------------------+-------------------------------------------------------+--------------------------------+---------------+
|        | DELETE uploads/destroy/{one?}/{two?}/{three?}/{four?}/{five?} |                      | UploadsController@deleteDestroy                       |                                |               |
|        | GET uploads/{_missing}                                        |                      | UploadsController@missingMethod                       |                                |               |
+--------+---------------------------------------------------------------+----------------------+-------------------------------------------------------+--------------------------------+---------------+

要按照表单打开行的方式使用您的表单，必须是:

Form::open(array('method' => 'GET', 'url' => array('uploads/destroy', $upload->id)))

但我认为现在的方式更好，只需重命名您的方法即可。
