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):

    from django.contrib.contenttypes import generic

我试图通过添加：

来导入通用

from django.contrib.contenttypes import generic

在models.py中。经过一些研究，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？

Answer 1

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

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

https://docs.djangoproject.com/en/1.7/ref/contrib/contenttypes/#generic-relations

Answer 2

此功能已移至.models和.fields模块中。它只是删除的特定文件;通用关系功能仍然存在，只是拆分成单独的文件。

Answer 3

从Python的官方网站更新Django.tagging包，而不是从Pip源更新，因为Pip没有最新版本。

ImportError：无法导入名称泛型
