试图在 Django 中找到 ImproperlyConfigured 错误

如何解决试图在 Django 中找到 ImproperlyConfigured 错误

我知道这个错误已经被问过很多次了，但是我阅读了很多帖子，但是我找不到解决我的问题的方法。谁能帮我找出我的错误在哪里？

它一直出现以下错误：

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")),]

trip\urls.py:

from django.urls import path

from . import views

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

我的项目树： Project Tree

当我从outside_world\urls.py 中删除path(r'trip/', 时，它运行良好，但我需要维护这一行。

解决方法

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

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

在 trip\views.py 中还有一个未定义的索引定义/类。如果你去 http(s)://YourIP/YourProjectName/trip .. 你应该定义 index.html 。 如果您正在输入以下内容之一，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 已经定义。
