尝试使用 django-subdomains 在我的 django urlpatterns 中查找循环引用？

Question

我正在为我的 Web 应用程序获取正确的 url conf，但我无所事事。

我认为django-subdomains背后的想法是子域路由存储在SUBDOMAIN_URLCONFS

ROOT_URLCONF = 'creativeflow'
# A dictionary of urlconf module paths, keyed by their subdomain.
SUBDOMAIN_URLCONFS = {
    None: ROOT_URLCONF + '.urls',  # no subdomain, e.g. ``example.com``
    'www': ROOT_URLCONF + '.urls',
    'blog': 'blog.urls',
}

那么我的creativeflow.urls和blog.urls是：

"""Creativeflow URL Configuration."""
from django.conf.urls import url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls, name="admin"),
]

和

"""Creativeflow URL Configuration the blog app."""
from django.conf.urls import url
from .views import BlogListView
urlpatterns = [
    url(r'posts/^(?P<year>\d{4})/(?P<months>\d{2}|\w{3})/(?P<day>\d{2})',
        BlogListView.as_view(paginate_by=25), name="blog-list-view")
]

我看到的错误是：

Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x046FA618>
Traceback (most recent call last):
  File "D:\creativeflow\myvenv\lib\site-packages\django\core\urlresolvers.py", line 419, in url_patterns
    iter(patterns)

During handling of the above exception, another exception occurred:

    raise ImproperlyConfigured(msg.format(name=self.urlconf_name))
django.core.exceptions.ImproperlyConfigured: The included URLconf 'creativeflow' 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.

我假设，如您所见，我在两个 urls.py 中都有一个 url 模式。所以我必须有一个循环引用。但是我已经通过 views.py 和 models.py 跟踪了导入，我没有看到任何会导致循环依赖问题的东西。

如何解决this/and找到循环依赖？

Answer 1

您的 ROOT_URLCONF 指向一个没有任何模式的模块。 ROOT_URLCONF 模块必须至少有一个 urlpatterns 属性，即使它是一个空列表。您可能希望它指向 creativeflow.urls。
