python - 导入错误 : cannot import name generic

Question

我正在使用 django 1.9 中的 eav-django(entity-attribute-value)。每当我执行命令 ./manage.py runserver 时，我都会收到错误:

Unhandled exception in thread started by <function wrapper at 0x10385b500>
Traceback (most recent call last):
  File "/Library/Python/2.7/site-packages/Django-1.9-py2.7.egg/django/utils/autoreload.py", line 226, in wrapper

    __import__(name)
  File "/Users/shakil_grofers/src/django-eav/eav/models.py", line 42, in <module>
    from django.contrib.contenttypes import generic

我试图通过添加导入泛型:

from django.contrib.contenttypes import generic 

在 models.py 中。然后经过一些研究，我发现泛型在 Django 1.7 中已被弃用，在 Django 1.9 中不再存在。谁能告诉我在 Django 1.9 中添加了这个功能的哪个其他库以及如何使用它？

django.contrib.contenttypes 模块已经reorganized in Django 1.7 .

您现在可以使用 django.contrib.contenttypes.fields.GenericForeignKey 而不是 django.contrib.contenttypes.generic.GenericForeignKey。请参阅文档中的示例代码:
