Wie behandelt man Laravel NotFoundHttpException?

Question

Ich lerne Laravel durch eine Selbstübung. Grundsätzlich möchte ich erreichen, dass der Parameter 'id' an den Controller von Route übergeben werden kann, um eine Liste verschiedener Themen für diese spezifische ID zu erhalten, wenn auf den Link geklickt wird. Ich habe alle anderen Beiträge überprüft und es scheint, dass ich dort die Antwort nicht bekommen kann.

Hier ist mein Code in Route.php, wo die Hauptseite die Indexseite meiner Anwendung ist.

Route::get('/public/', array('as' => 'Personal_assistant' , 'uses' => 'category_by_user@get_mainpage')); 
Route::get('public/{id}' , array('as' => 'viewtopic' , 'uses' => 'category_by_user@get_topic')); 

Mein Code in Controller 'category_by_user':

class Category_by_user extends Controller 
{ 
// 

public $restful = true; 

public function get_mainpage() 
{ 

$data = DB::table('categories') 
     -> select('category_name', 'category_description') 
    //->where('category_user_id', '=' , $user_id) 
    ->get(); 

    return view::make('mainpage') 
     ->with('title', 'Category By User') 
     ->with('data' , $data); 
    } 


    public function get_topic($id) 
    { 
     $data1 = DB::table('topics') 
     ->where('Category_id', '=' , $id) 
     ->get(); 


     return View::make('viewtopic') 
     ->with('title', 'All Topic by Category') 
     ->with('data1' , $data1) 
     ->with('id' , $id); 
     } 
} 

Mein Code in viewtopic.blade.php:

{h1>Personal Info Assistant</h1> 

    <!-- will be used to show any messages --> 
    @if (Session::has('message')) 
     <div class="alert alert-info">{{ Session::get('message') }}</div> 
    @endif 

    <table class="table table-striped table-bordered"> 

    <tbody> 
    <!-- // List all categories belongs to that particular user --> 


    @foreach($data1 as $key => $topic) 
     <tr> 

     <td>{{ $topic->topic_description }}</td> 
     <td>ID = {{ $id }}</td> 

     </tr> 
    @endforeach 
    </tbody> 
</table> 

</div> 
</body> 
</html>

Vielen Dank für Fortgeschrittene jede Hilfe da draußen.

Answer 1

Können Sie die Links und den Code, der in Ihren Links die ID übergibt? Vielleicht wird die $ ID in Ihrem href attr nicht korrekt übergeben.
