Question

我目前正在使用Python Django编写一个Web应用程序。我的问题是，我最近安装了django-relations，将它添加到settings.py中的INSTALLED_APPS。

从那以后我收到了这个有线错误，我不知道这意味着什么。

有人可以帮助我吗？

Answer 1

似乎django-relationships取决于Site模型。您也必须将django.contrib.sites添加到INSTALLED_APPS。

第二个错误表示django-relationships尝试从create_many_related_manager导入django.db.models.fields.related。在Django 1.9中删除了此功能。如果有更新的版本，您可以尝试这是否有效。如果没有，django-relationships不适用于Django 1.9。
