Django 注册中的完整性错误

Question

所以我在 django 1.8 中遇到了这个错误。 和 django-registration-redux 1.1 。 它不允许我从 3 周起睡觉。 帮助会很好。

如果还有其他问题需要质疑答案，请告诉我，我是框架和 django 的新手。 所以我真的不太了解它。

Answer 1

我和你有同样的问题。 我试图改变网址，如：

url(r'^accounts/', include('registration.backends.simple.urls')),

希望这可以帮助。

Answer 2

我认为您安装了错误版本的 Django 注册。

回溯包含

/registration/backends/model_activation/views.py in register

但是 django-registration-redux 中不存在model_activation后端（请参阅 GitHub 上的目录）。 我认为您安装了 django-registration（不是 redux）2.x。

如果您正在学习教程，请务必确保安装了软件包和版本，否则您会遇到这样的问题。

Answer 3

完全删除您的数据库。 在您的情况下，删除与您的manage.py相同文件夹中的db.sqlite3 。 将.py文件保存在<your app>/migrations文件夹中，不要删除它们。

然后运行python manage.py migrate

然后在数据库中再次设置所有数据。
