管理员站点:在/ admin /的TemplateDoesNotExist

Question

我正在关注Django的官方教程2,但由于某种原因,尽管按照我的理解正确地执行了所有步骤,但仍无法创建管理站点.

这是我得到的错误:

TemplateDoesNotExist at /admin/
admin/login.html
Request Method: GET
Request URL:    http://127.0.0.1:8000/admin/
Django Version: 1.3.1
Exception Type: TemplateDoesNotExist

取消注释以下行(注释)后发生错误:

### urls.py ###
from django.conf.urls.defaults import patterns, include, url

from django.contrib import admin # THIS LINE
admin.autodiscover() # THIS LINE

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)), # THIS LINE
)

如果我再次评论它,它将摆脱错误.

我也有django.contrib.admin我的settings.py中INSTALLED_APPS

Answer 1

我遇到了同样的问题,我不得不强迫pip重新下载django.

pip install -r requirements.txt --ignore-installed --force-reinstall --upgrade --no-cache-dir

注意:我知道该--no-cache-dir选项是必要的,我不确定其他选项是否都是必需的.

Answer 2

我正在使用Django版本1.9.7,当我尝试将admin_tools(菜单和仪表板)添加到我的应用程序时,我遇到了类似的问题.我发现我必须做三件事:

1. 编辑settings.py中的INSTALLED_APPS选项,如下所示(请注意,admin_tools位于django contrib之前,'mines'是我的应用程序的名称):

   INSTALLED_APPS = [
       'admin_tools',
       'admin_tools.theming',
       'admin_tools.menu',
       'admin_tools.dashboard',
       'django.contrib.admin',
       'django.contrib.auth',
       'django.contrib.contenttypes',
       'django.contrib.sessions',
       'django.contrib.messages',
       'django.contrib.staticfiles',
       'mines'
   ]
   

2. 编辑settings.py文件中的TEMPLATE设置,如下所示(注意添加的'loaders'选项,APP_DIRS现在设置为false):

   TEMPLATES = [{
       'BACKEND': 'django.template.backends.django.DjangoTemplates',
       'DIRS': [],
       'APP_DIRS': False,
       'OPTIONS': {
           'context_processors': [
               'django.template.context_processors.debug',
               'django.template.context_processors.request',
               'django.contrib.auth.context_processors.auth',
               'django.contrib.messages.context_processors.messages',
           ],
           'loaders': [
               'django.template.loaders.filesystem.Loader',
               'django.template.loaders.app_directories.Loader',
               'admin_tools.template_loaders.Loader',
           ],
       },
   }]
   

3. 最后我更新了我的urls.py文件,如下所示(注意admin_tools网址的包含):

   from django.conf.urls import include,url
   from django.contrib import admin
   from mines.views import SummaryByMapIcon
   
   urlpatterns = [
       url(r'^admin_tools/', include('admin_tools.urls')),
       url(r'^admin/', admin.site.urls),
       url(r'^summarybymapicon$', SummaryByMapIcon, name='summarybymapicon'),
   ]
   

Answer 3

我通过--no-cache-dir选项重新安装Django解决了同样的问题:

pip uninstall django
pip install django --no-cache-dir

解决了这里的答案.

Answer 4

由于它适用于其他人的机器，并且由于您启用了应用程序目录加载器，在INSTALLED_APPS.您的 Django 安装有问题。

这将是开始使用 virtualenvs 和全新安装的 django 来排除您的设置的好机会：

启动终端，导航到您的项目目录（实际上无关紧要...）

pip install virtualenv # if you don't have it.

virtualenv --no-site-packages env 
# this creates a virtual python environment that doesn't include system packages

source env/bin/activate
# this forces your bash session to use that environment

pip install django
# installs a fresh copy of django to your new environment

cd path_to_my_django_project    
# now go to your site directory

python manager.py runserver
# visit admin site.

Answer 5

就我而言，我不得不改变APP_DIRS来自False于True

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]
