Good day, Am trying t return a view from login valdiation but an error keeps showing "No query results for model [App\Nurse].". In this case my model "Nurse" exists and the error keeps showing. The code is as below

public function postSignIn(Request $request) {

    $this->validate($request, [

        'email' => 'required',
        'password' => 'required'

    ]);

   if(Auth::attempt(['email' => $request['email'], 'password' => $request['password']])) {
       $user=User::whereRaw('email=?',[Input::get('email')])->first();

       if($user!=null){
           switch($user->role_id){
               case 1:
                   if($user->status==0){
                       session()->flash('flash_message_error', ' Your Account has been  deactivated. Contact the administrator');
                       return Redirect::to('admin/login');
                   }
                   return redirect()->route("index");
               break;

               case 2:
                   $doctor=Doctor::where('user_id',$user->id)->first();

// dd($doctor); if($user->status==0){ session()->flash('flash_message_error', 'Your Account has been deactivated. Contact the administrator'); return Redirect::to('admin/login'); } return redirect()->route("dashboard")->with(compact('doctor')); break;

               case 3:
                   $nur=Nurse::where('user_id',$user->id)->first();

// dd($doctor); if($user->status==0){ session()->flash('flash_message_error', 'Your Account has been deactivated. Contact the administrator'); return Redirect::to('admin/login'); } return redirect()->route("NurseDashboard")->with(compact('nur')); break;

The first and second case statements work but the thrid case method keeps retuning no query found in Add/Nurse
