连接 Django 调试工具栏的问题

Question

在此处输入图像描述 我像在指令中一样连接，当运行服务器时一切正常，但是当打开站点时，我看到错误：

'djdt' is not a registered namespace

我该怎么办？有什么连接问题？

setting.py

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
DEBUG = True
ALLOWED_HOSTS = ['127.0.0.1']
INTERNAL_IPS = ['127.0.0.1',]
INSTALLED_APPS =  [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'news',
'django_summernote',
'debug_toolbar',
]
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'debug_toolbar.middleware.DebugToolbarMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
STATIC_URL = '/static/'
MEDIA_URL = '/media/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, "static"),]
MEDIA_ROOT = os.path.join(BASE_DIR, "media")

urls.py

app_name = 'news'
urlpatterns = [
...
]
if settings.DEBUG:
import debug_toolbar
urlpatterns += [path('__debug__/', include(debug_toolbar.urls)),]
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

我不知道为什么会有错误。我做了所有写在教学中的事情。可能是静态根的问题？

安装时的 djdt 文档显示，您需要在其余 url 模式之前包含'__debug__/'路径。您应该将代码更改为以下内容：

if settings.DEBUG:
import debug_toolbar
urlpatterns = [
path('__debug__/', include(debug_toolbar.urls)),
] + urlpatterns
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
