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

你知道是什么原因导致这个错误吗？

编辑

按照 huck Harmston 说明 Site.objects.get(pk=settings.SITE_ID) 返回此错误

在我的数据库中有一个site_id http://127.0.0.1:8000/'，这是我使用的域名，而不是example.com`

Answer 1

您的 SITE_ID 设置的值可能与 Site 对象的主键不对应。您可以通过运行以下命令进行验证:

$ ./manage.py shell
Python 2.7.1 [...]
>>> from django.contrib.sites.models import Site
>>> from django.conf import settings
>>> Site.objects.get(pk=settings.SITE_ID)
<Site: example.com>

如果最终命令的响应不是 Site 对象(它可能会引发 Site.DoesNotExist 异常)，那么这就是问题所在。您可以通过不设置SITE_ID来解决这个问题，如果您不使用 django.contrib.sites 则不需要设置。 .
