我在django 1.9中使用eav-django（entity-attribute-value）。每当我执行命令时 ./manage.py runserver ，我收到了错误：
Unhandled exception in thread started by <function wrapper at 0x10385b500>
Traceback (most recent call last):

from django.contrib.contenttypes import generic
我尝试通过添加以下方式导入泛型：
from django.contrib.contenttypes import generic
在models.py中。经过一些研究后，我发现在Django 1.7中已经弃用了泛型，而在Django 1.9中已经不再使用了泛型。任何人都可以告诉我在Django 1.9中添加了哪些其他库以及如何使用它？
