What does "Method [show] does not exist" mean?
提问by mario
I'm new to Laravel 4 and trying to figure out why I'm getting an error saying that Method [show] does not exist.
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。
I do not have a method named "show"and can only imagine that this is an internal, Laravel method but I do not know how to affect this or what could have done this. Any thoughts or help on this would be incredibly appreciated as I have been stuck on this for two days now and cannot figure out what I am doing wrong.
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激，因为我已经坚持了两天并且无法弄清楚我做错了什么。
View:
看法：
<li><a href="{{ URL::route('account-sign-in') }}">Sign in</a></li>
Route:
路线：
/*Sign In (GET)*/
Route::get('/account/sign-in', array(
'as' => 'account-sign-in',
'uses' => 'AccountController@getSignIn'
));
AccountController:
帐户控制器：
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.');
}
}

Code provided in your question doesn't shows anything about show()method, anyways. According to to your comments you didn't extend the BaseControllerbut all your controlers should extend the BaseController and the BaseControllershould extend the Controllerso this is how your BaseControllershould look like (By default):
show()无论如何，您的问题中提供的代码没有显示任何有关方法的信息。根据您的评论，您没有扩展，BaseController但您的所有控制器都应该扩展 BaseController 并且BaseController应该扩展，Controller所以这就是您的BaseController外观（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);
}
}
}
Your controller should extend it like this:
您的控制器应该像这样扩展它：
class AccountController extends BaseController {
// Define all of your methods
// including show() if you are using it
}

It sounds like you just have a typo on the first line of your AccountController
听起来你只是在 AccountController 的第一行有一个错字
It probably says class AccountController extends BasesController {
它可能会说 class AccountController extends BasesController {
BasesControllershould be BaseController
BasesController应该 BaseController

I had this problem. I had previously listed a (now deprecated) resource that was causing a collision in the routes.php file.
我有这个问题。我之前列出了一个（现已弃用）资源，该资源导致 routes.php 文件中的冲突。
Route::resource('scheduler', 'SchedulerController');
Route::get('scheduler/notices', 'SchedulerController@notices');
