Laravel 4 - 未找到控制器方法

Question

我想從列表中修改用戶。我有代碼的routes.php文件：

Route::get('users/{all}/edit', 'UserController@getEdit'); 
Route::post('users/update', ['as' => 'users.postUpdate', 'uses' => 'UserController@postUpdate']); 
Route::controller('users', 'UserController'); 

在UserController.php，我寫了下面的腳本進行編輯和更新：

public function getEdit($id) 
{ 
    // 

    $user = User::find($id); 
    if (is_null($user)) 
     { 

      return Redirect::to('users/all'); 
     } 
    return View::make('users.edit', compact('user')); 
} 


/** 
* Update the specified resource in storage. 
* 
* @param int $id 
* @return Response 
*/ 
public function postUpdate($id) 
{ 
    // 


    $input = Input::all(); 
    $validation = Validator::make($input, User::$rules); 
    if ($validation->passes()) 
    { 
     //$user = User::find($id); 

      $user = User::find($id); 
      $user->username = Input::get('username'); 
      $user->name = Input::get('name'); 
      $user->email = Input::get('email'); 
      $user->phone = Input::get('phone'); 
      $user->password = Hash::make(Input::get('password')); 
      $user->save(); 

     return Redirect::route('users.getIndex', $id); 
    } 
    return Redirect::route('users.getEdit', $id) 
     ->withInput() 
     ->withErrors($validation) 
     ->with('message', 'There were validation errors.'); 
} 

如下下edit.blade.php代碼：

@extends('users.user') 

@section('main') 

<h1>Edit User</h1> 
{{ Form::model($user, array('method' => 'PATCH', 'route' => array('users.postUpdate', $user->id))) }} 
<ul> 
    <li> 
     {{ Form::label('username', 'Username:') }} 
     {{ Form::text('username') }} 
    </li> 
    <li> 
     {{ Form::label('password', 'Password:') }} 
     {{ Form::text('password') }} 
    </li> 
    <li> 
     {{ Form::label('email', 'Email:') }} 
     {{ Form::text('email') }} 
    </li> 
    <li> 
     {{ Form::label('phone', 'Phone:') }} 
     {{ Form::text('phone') }} 
    </li> 
    <li> 
     {{ Form::label('name', 'Name:') }} 
     {{ Form::text('name') }} 
    </li> 
    <li> 
     {{ Form::submit('Update', array('class' => 'btn btn-info')) }} 
     {{ link_to_route('users.getAll', 'Cancel', $user->id, array('class' => 'btn')) }} 
    </li> 
</ul> 
{{ Form::close() }} 

@if ($errors->any()) 
<ul> 
    {{ implode('', $errors->all('<li class="error">:message</li>')) }} 
</ul> 
@endif 

@stop 

編輯屏幕開放良好。然而，當修改值並提交表單，網址顯示爲http://localhost/testlaravell/users/update?5並出現錯誤 -

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

請幫助我，我怎麼能解決這個問題。

Answer 1

這裏的問題是，你使用PATCH方法，但在控制器中你有方法postUpdate（和routes.php相同）。

什麼你應該做的是：

• 改變控制器方法postUpdate到putUpdate

• 改變

  Route::post('users/update', ['as' => 'users.postUpdate', 'uses' => 'UserController@postUpdate']); 
  

  到

  Route::put('users/update/{id}', ['as' => 'users.putUpdate', 'uses' => 'UserController@putUpdate']); 
  

• 改變你的形式

  {{ Form::model($user, array('method' => 'PATCH', 'route' => array('users.postUpdate', $user->id))) } 
  

  到

  {{ Form::model($user, array('method' => 'PUT', 'route' => array('users.putUpdate', $user->id))) } 
  

Answer 2

定義您的路線是這樣的：

Route::resource('users', 'UsersController'); 

更改：

{{ Form::model($user, array('method' => 'PATCH', 'route' => array('users.postUpdate', $user->id))) }} 

到

{!! Form::model($user, array('method' => 'PATCH', 'route' => array('users.update', $user->id))) !!} 

寫您的控制器是這樣的：

public function edit($id) 
    { 
     $user = User::find($id); 
     if (is_null($user)) 
     { 

      return Redirect::to('users/all'); 
     } 
    return View::make('users.edit', compact('user')); 
} 


/** 
* Update the specified resource in storage. 
* 
* @param int $id 
* @return Response 
*/ 

public function update($id) 
{ 
    $input = Input::all(); 
    $validation = Validator::make($input, User::$rules); 
    if ($validation->passes()) 
    { 

      $user = User::find($id); 
      $user->username = Input::get('username'); 
      $user->name = Input::get('name'); 
      $user->email = Input::get('email'); 
      $user->phone = Input::get('phone'); 
      $user->password = Hash::make(Input::get('password')); 
      $user->save(); 

     return Redirect::route('users.getIndex', $id); 
    } 
    return Redirect::route('users.getEdit', $id) 
     ->withInput() 
     ->withErrors($validation) 
     ->with('message', 'There were validation errors.'); 
} 

希望，它會工作。
