Trying to trace a circular import error in Django
提问by Tatenda
I understand circular import error has been asked about a lot but after going through these questions I haven't been able to solve my issue. When I try to run my server in Django its giving me this error message:
我知道很多人都问了循环导入错误，但是在解决了这些问题之后，我还是没能解决我的问题。当我尝试在 Django 中运行我的服务器时，它给了我这个错误消息：
The included URLconf module 'accounts_app' from path\to\myproject\__init__.py 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.
path\to\myproject\__init__.py 中包含的 URLconf 模块“accounts_app”似乎没有任何模式。如果您在文件中看到有效模式，则问题可能是由循环导入引起的。
The issue started when i added a new app which has a urls.py like the following
当我添加一个新的应用程序时，问题就开始了，该应用程序的 urls.py 如下所示
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^signin$', views.signin, name='signin'),
url(r'^signout$', views.signout, name='signout'),
url(r'^signup$', views.signup, name='signup'),
]
My project urls.py has a line which points to the app and looks like the following code
我的项目 urls.py 有一行指向应用程序，如下所示
urlpatterns = [
url(r'^accounts/', include('accounts_app')),
]
My view looks like the following:
我的观点如下：
from django.shortcuts import render
from django.http import HttpResponse
def signin(request):
return HttpResponse("<p>This the signin view</p>")
def signout(request):
return HttpResponse("<p>This the signout view</p>")
def signup(request):
return HttpResponse("<p>This the signup view</p>")
Can anyone please help me identify were I could possibly be going wrong.
任何人都可以帮我确定我可能会出错。

Try changing
尝试改变
urlpatterns = [
url(r'^accounts/', include('accounts_app')),
]
to
到
urlpatterns = [
url(r'^accounts/', include('accounts_app.urls')), # add .urls after app name
]

In my case I was getting error because I was giving wrong path of dir containing urls. So I changed this
在我的情况下，我收到错误，因为我给出了包含 url 的错误路径。所以我改变了这个
urlpatterns = [
url(r'^user/', include('core.urls'))
]
to this
对此
urlpatterns = [
url(r'^user/', include('core.urls.api'))
]

for those who have the same error but still hasn't debugged their code, also check how you typed "urlpatterns"
对于那些有同样错误但仍然没有调试他们的代码的人，还要检查你是如何输入“urlpatterns”的
having it mistyped or with dash/underscore will result to the same error
输入错误或使用破折号/下划线将导致相同的错误

Those habitual with CamelCased names may face the error as well.
那些习惯使用 CamelCased 名称的人也可能面临这个错误。
urlpatternshas to be typed exactly as 'urlpatterns'
urlpatterns必须完全输入为“urlpatterns”
This will show you error -
这将向您显示错误 -
urlPatterns = [
path('', views.index, name='index'),
Error -
错误 -
django.core.exceptions.ImproperlyConfigured: The included URLconf '<module 'polls.urls' from '...\polls\urls.py'>' 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.
However, fixing the CamelCase will work -
但是，修复 CamelCase 将起作用-
urlpatterns = [
path('', views.index, name='index'),
]

In my case i was getting this error because i was typing urlpatternsin urls.py to urlpattern.
在我来说，我在得到这个错误，因为我打字URL模式在urls.py到 URLPATTERN。

This error also appears if SomeView doesn't exist in views.py and you do this:
如果在 views.py 中不存在 SomeView 并且您执行以下操作，也会出现此错误：
from someapp import views
urlpatterns = [
path('api/someurl/', views.SomeView.as_view(), name="someview"),
]
So make sure all Views you use in urls.py exist in views.py
因此，请确保您在 urls.py 中使用的所有视图都存在于 views.py 中
