如何修复以下有关获取 URL 的错误

Question

我无法访问(获取(程序中提到的那些网址

urls.py

from django.conf.urls import include, url
from rest_framework import routers
from imgstore.views import QueryImage
from imgstore.views import ImageActionViewSet

# this is DRF router for REST API viewsets
router = routers.DefaultRouter()
router.register(r'api/v1/imgaction', ImageActionViewSet, r"imgaction")
router.register(r'api/v1/queryimage', QueryImage, r"queryimage")

urlpatterns = [
    url(r'', include(router.urls, namespace='imgaction')),
    url(r'', include(router.urls, namespace='queryimage'))
]

我收到此错误：

django.core.exceptions.ImproperlyConfigured: The included URLconf 'image_storage.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.

而且我不知道要解决它。我错过了什么？

Answer 1

检查 django 应用程序中可能存在的文件 urls.py image_storage。它应该包含一个有效的 django url 配置，而不是空！

Answer 2

很多时候，这是由 Django 的 resolvers.py 试图消耗你的 urls.py 时的一些异常引起的。

我通常解决它的方法是将我的整个 urls.py 文件(以及所有其他 urls.py 文件(包装在一个 try-except 块中，并打印被捕获的异常，这通常比 Django 提供的默认文件更直接地解决问题。

祝你好运！
