methods - "Method [show] does not exist"是什么意思？

Question

我是 Laravel 4 的新手，并试图弄清楚为什么我收到一个错误，说 Method [show] 不存在。

我没有名为“show”的方法，只能想象这是一个内部的 Laravel 方法，但我不知道如何影响它或可能会发生什么。对此的任何想法或帮助将非常感谢，因为我已经坚持了两天并且无法弄清楚我做错了什么。

看法:

<li><a href="{{ URL::route('account-sign-in') }}">Sign in</a></li>

路线:

/*Sign In (GET)*/
    Route::get('/account/sign-in', array(
        'as'    => 'account-sign-in',
        'uses'  => 'AccountController@getSignIn'
    ));

帐户 Controller :

class AccountController extends BaseController { 
  public function getSignIn(){ 
    return View::make('user.signIn'); 
  } 

  public function postSignIn(){ 
    $validator = Validator::make(Input::all(), array( 'email' => 'required|email', 'password' => 'required' ) ); 
    if($validator->fails()){ /*Redirect to the sign in page*/ 
      return Redirect::route('account-sign-in') ->withErrors($validator) ->withInput();
    } 
    else { /*Attempt user sign in*/ 
      $remember = (Input::has('remember')) ? true : false;
      $auth = Auth::attempt(array( 'email' => Input::get('email'), 'password' => Input::get('password'), 'active' => 1 ), $remember); 
      if($auth){ 
        /*Redirect to the intended page*/ return Redirect::intended('/'); 
      } 
      else {
        return Redirect::route('account-sign-in')->with('global', 'Email/password wrong, or account not activated.'); 
      } 
    } 
    return Redirect::route('account-sign-in') ->with('global', 'There was a problem signing you in.'); 
  } 
}

What does “Method [show] does not exist” mean?

您的问题中提供的代码没有显示有关 show() 的任何信息方法，反正。根据您的评论，您没有扩展 BaseController但是你所有的 Controller 都应该扩展 BaseController 和 BaseController应该扩展 Controller所以这就是您的 BaseController应该看起来像(默认情况下):

class BaseController extends Controller {

   /**
    * Setup the layout used by the controller.
    *
    * @return void
    */
    protected function setupLayout()
    {
        if ( ! is_null($this->layout))
        {
            $this->layout = View::make($this->layout);
        }
    }
}

您的 Controller 应该像这样扩展它:

class AccountController extends BaseController {

    // Define all of your methods
    // including show() if you are using it

}
