Laravel 4 удалить файл используя ajax

Пожалуйста, помогите мне решить мою проблему в моем файле удаления в моем проекте, я запутался, потому что он всегда возвращает мне нулевое значение

вот мой editfile.blade.php

@include('partials.navbar')

console.log(info);
$('#deletefileid').val(info.id);
},
error:function(){
alert("failure");
}
});
});
});
</script>

вот моя модель file.php

public static function getdeleteFiles($deleteid)
{
$files = Files::find($deleteid);
$files->delete();
}

вот мой контроллер FileController.php

public function eraseFile($id)
{
$files = Files::where('id',$id)
->get();
return json_encode($files);
}

public function deleteFile()
{
dd(Input::all());
$ftype = Input::get('type');
$oldfile = Input::get('oldfile');
$deleteid = Input::get('deleteid');
$delete = Files::getdeleteFiles($deleteid);
//dd($deleteid);
if ($delete == true) {
File::delete(public_path("uploads/{$ftype}/{$oldfile}"));
return Redirect::to('/edit');
} else {
return Redirect::back()->with('message', 'Delete, Failed');
}
}

и вот мой маршрут

Route::get('/erasefile/{id}', 'FileController@eraseFile');
Route::post('/deletefile', array('uses' => 'FileController@deleteFile'));

Пожалуйста, помогите мне решить эту TIA!
