объекта «Мета» не имеет атрибута «абстрактный»

Question

У меня есть эта ошибка:

**'Meta' object has no attribute 'abstract'** 

Это произошло после того, как я установил новое приложение Джанго, он обновляется Джанго версией 1.5, я изменил его обратно на 1.3, но я все еще есть та же проблема!

Теперь ни один из моих проектов больше не работает!

Answer 1

кажется, что я должен был вернуться к Джанго 1.2, чтобы решить вопрос
