再次尝试实现Django注册。当我尝试将它部署到heroku并注册一个新用户时，它给了我一个奇怪的错误：

Traceback:

#some irrelevant traceback

File "/app/.heroku/python/lib/python2.7/site-packages/registration/views.py" in post

  387.                 self.model._meta.object_name

Exception Type: DoesNotExist at /accounts/register/
Exception Value: Site matching query does not exist.

我完全遵循官方documentation。
应该在哪里查找错误？问题出在哪里？

heroku

如果您的INSTALLED_APPS中有django.contrib.sites，并且您没有多个站点，那么您必须删除它并执行一轮makemigration和migrate。
如果您有多个站点，请参考：Django - Site matching query does not exist

从this添加。这应该工作
进入Django shell

$> ./manage.py shell
>>> from django.contrib.sites.models import Site
>>> site = Site()
>>> site.domain = 'example.com'
>>> site.name = 'example.com'
>>> site.save()

在django INSTALLED_APPS中添加django.contrib.sites，并在django设置文件中添加SITE_ID=1。
