解决方案

您对管理URL应该是：结果
URL（R'^管理员/'，包括：（admin.site.urls））结果
没有（R'^管理员/(.*），admin.site.root）结果
- 它是Django的1.0。对于Django的1.3这是行不通的。

Edit in response to Aldarund:

Yes, I did correct the URL for admin, but now it is giving a database error. What could be the problem? Here is the traceback:

解决方案

Your url for admin should be:
url(r'^admin/', include(admin.site.urls))
not (r'^admin/(.*)', admin.site.root)
- it's for Django 1.0. For Django 1.3 it wouldn't work.
