No, you cannot use App::missing('Controller@method')directly, because the method missingcalls the method error, namely:
public function error(Closure $callback)
{
$this['exception']->error($callback);
}
, controller → method . . , , , .
/ , ( , ) , ?
Update:
App::missing(function($e){
$var = 'SomeValue' from model
return Response::view('errors.404', array('error'=> $e, 'another' => $var));
});
