Django filter query - не работает

Question

У меня проблемы с моим Django, я хочу написать очень простой запрос, но он не работает.

Модель:

class Games(models.Model): 
    name = models.CharField(max_length=128) 
    path_to_folder = models.CharField(max_length=256) 
    description = models.TextField() 
    cover = models.URLField() 

    def __str__(self): 
     return self.name 

Я пытаюсь что-то вроде этого (Он должен найти себя, на мой взгляд):

>>> from gamepanel.models import Games 
>>> e = Games.objects.all() 
>>> print (e) 
[<Games: Call Of Duty 4>] 
>>> e[0].name 
'Call Of Duty 4' 
>>> q = Games.objects.filter(name=e[0].name) 

, но когда я написал последнюю строку и нажмите клавишу ВВОД, я получаю:

Traceback (most recent call last): 
File "/home/zoli/Desktop/django-master/newest/django-trunk/django/db/models/options.py", line 404, in get_field_by_name

raise AppRegistryNotReady("Models aren't loaded yet.") 

django.core.exceptions.AppRegistryNotReady: Модели не загружены.

Я понятия не имею, что я делаю неправильно, я также попытался сделать то же самое с .id, но он не работает ни с одним.

В Django 1.7 и более поздних версиях вы не можете использовать модели без явной инициализации Django. Выполните следующие команды:

import django 
django.setup() 

И после этого ваши запросы будут работать.
