编辑以响应 Aldarund< /a>:

是的，我确实更正了管理员的 URL，但现在它给出了数据库错误。可能是什么问题？这是回溯：

Answer 1

您的管理员网址应该是：
url(r'^admin/', include(admin.site.urls))
不是 (r'^admin/(.*)', admin.site.root)
- 适用于 Django 1.0。对于 Django 1.3 来说它不起作用。

Answer 2

我遇到的另一个可能的问题是，admin 尚未在 settings.py 文件中正确配置。遇到此问题的任何人都需要检查他们安装的应用程序是否包含 django.contrib.admin。参考 https://docs.djangoproject.com/en/1.3/faq/admin/< /a> 了解详细信息。
