python - 连接 Django 调试工具栏时出现问题

Question

enter image description here我按照说明进行连接，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？什么连接问题？

设置.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)

不知道为什么会出现错误。我做了指令中写的所有内容。静态根可能有问题吗？

The djdt docs on installation表明您需要在其余网址模式之前包含 '__debug__/' 路径。您应该将代码更改为:

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)
