php - laravel filter group routes with same name -

i'm stuck annoying problem in laravel 4 project wich has 3 types of users being students, teachers , moderator (i use entrust role management solution).

each of them can browse same route, depending on user type, method should called. route.php files structured this:

route::group(array('before' => 'auth'), function(){   route::group(array('before' => 'teacher'), function(){         route::get('/tasks',array('as'=>'tasks','uses'=>'taskscontroller@tasksasteacher'));         route::get('/task/{id}',array('as'=>'showtask','uses'=>'taskscontroller@showtaskasteacher'));    }); route::group(array('before' => 'moderator'), function(){         route::get('/tasks',array('as'=>'tasks','uses'=>'taskscontroller@tasksasmoderator'));         route::get('/task/{id}',array('as'=>'showtask','uses'=>'taskscontroller@showtaskasmoderator'));  });      route::group(array('before' => 'student'), function(){          route::get('/tasks',array('as'=>'tasks','uses'=>'taskscontroller@tasksasstudent'));         route::get('/task/{id}',array('as'=>'showtask','uses'=>'taskscontroller@showtaskasstudent'));     });  }); 

however, browsing these routes teacher or moderator account returned 404 errors. found because routes redefined in 2 other filter groups.

so if redirect teacher user 'showtask', laravel return tasks route students,as that's last time 'showtask' route redefined, , 404 error.

my question was: best way handle error?

i hope isn't messy. in advance!

taking @matthias s's answer, work? instead of using entrust filter, check permissions route this:

//routes.php  if(entrust::hasrole('teacher')) {      route::get('/tasks',array('as'=>'tasks','uses'=>'taskscontroller@tasksasteacher'));      route::get('/task/{id}',array('as'=>'showtask','uses'=>'taskscontroller@showtaskasteacher'));  } 

repeat different roles

edit: if had role of user stored in session, use sort of automatic route this:

//routes.php  if(entrust::hasrole(session::get('role'))) {      route::get('/tasks',array('as'=>'tasks','uses'=>'taskscontroller@tasksas'.session::get('role')));      route::get('/task/{id}',array('as'=>'showtask','uses'=>'taskscontroller@showtaskas'.session::get('role')));  } 

this way can add many roles want once add correct controller function role.

edit #2:

or guess better

//routes.php - updated, verify role inside controller instead of defining routes based on role      route::get('/tasks',array('as'=>'tasks','uses'=>'taskscontroller@tasks'));      route::get('/task/{id}',array('as'=>'showtask','uses'=>'taskscontroller@showtask'));   //taskscontroller.php public function __construct(){     if(!session::get('role')){ //make sure user has role assigned         return redirect::to('login'); // redirect login or permission screen if not     } }  public function tasks(){     if(entrust::hasrole(session::get('role')){         $tasks = tasks::where('role_id', '=', $role->id); // tasks based on role         view::make('tasks.index')->with('tasks', $tasks);     } else{         // show permissions error user     } }  public function showtask($task_id){     if(entrust::hasrole(session::get('role')){         $task = tasks::where('role_id', '=', $role->id)->where('id', '=', $task_id)->first();         view::make('tasks.view')->with('task', $task);     } }
