试图在 Django 中找到 ImproperlyConfigured 错误

Question

我知道这个错误已经被问了很多，但是我阅读了很多帖子，但我找不到我的问题的解决方案。谁能帮我找出我的错误在哪里？

一直出现如下错误：

django.core.exceptions.ImproperlyConfigured: The included URLconf 'outside_world.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.

outside_world\urls.py（项目的网址）：

from django.contrib import admin
from django.urls import path, include
from . import views

urlpatterns = [
    path(r'admin/', admin.site.urls),
    path(r'', views.detail, name='detail'),
    path(r'trip/', include("trip.urls")),
]

行程\urls.py:

from django.urls import path

from . import views

urlpatterns = [
    path('', views.index, name='index'),
    path('<int:question_id>/', views.detail, name='detail'),
    path('<int:question_id>/results/', views.results, name='results'),
    path('<int:question_id>/vote/', views.vote, name='vote'),
]

trip\views.py:

from django.shortcuts import render
from django.http import HttpResponse

def detail(request, question_id):
    return HttpResponse("You're looking at question %s." % question_id)

def results(request, question_id):
    response = "You're looking at the results of question %s."
    return HttpResponse(response % question_id)

def vote(request, question_id):
    return HttpResponse("You're voting on question %s." % question_id)

当我从 outside_world\urls.py 中删除 path(r'trip/', include("trip.urls")), 时，它工作得很好，但我需要维护这一行。

将这两个 url 移动到项目的 urls.py 并从 outside_world\urls.py 中移出

path(r'admin/', admin.site.urls)
path(r'trip/', include("trip.urls"))

此外，trip\views.py 中有一个未定义的索引定义/类。如果你去 http(s)://YourIP/YourProjectName/trip 会导致错误。你应该定义 index. 如果您正在键入以下内容之一，它将正常工作，因为您已经定义了这些视图。 Number 是您定义的整数 (QuestionID)

• http(s)://YourIP/YourProjectName/trip/Number 或
• http(s)://YourIP/YourProjectName/trip/Number/results 或
• http(s)://YourIP/YourProjectName/trip/Number/Vote 因为它们是 已定义。
