Я обновляю свое приложение django с Django 1.5 до Django 1.7.При обновлении я получаю django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet ошибку.Я попытался с некоторым решением, которое я получил, ища.Но ничего не работает для меня.Я думаю это из-за одной моей модели.Пожалуйста, помогите мне исправить это.
