无法加载管理界面

Question

我创建了一个新的 Django 项目，我可以在其中访问http://127.0.0.1:8000，但我无法访问管理仪表板http://127.0.0.1:8000/admin/。

已安装的应用程序

INSTALLED_APPS = (
    'admin_tools',
    'admin_tools.theming',
    'admin_tools.menu',
    'admin_tools.dashboard',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    #'django.contrib.sites',

    'django.contrib.messages',
    'health',

    # Uncomment the next line to enable the admin:
     'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
     'django.contrib.admindocs',
)

网址

from django.conf.urls import patterns, include, url
from django.contrib import admin
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$','authentication.views.login_authenticate'),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^admin_tools/', include('admin_tools.urls')),
)

如果您只从项目中运行一个站点，则您实际上并不需要站点框架，因此最简单的解决方法是从您的 INSTALLED_APPS 中删除以下项目，并且错误应该会消失：

'django.contrib.sites'

您还可以从 shell 重新创建缺少的站点对象。运行 python manage.py shell 然后：

from django.contrib.sites.models import Site
Site.objects.create(pk=1, domain='www.xxx.com', name='xxx.com')

我想这可能会对你有所帮助。
