【问题描述】：

我希望这个博客页面能够运行。我正在使用 django==1.11.2，其中我有 2urls.py 与 include 链接，但是在运行时我遇到了递归错误问题。

主 urls.py:

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^blog/', include('project1.urls')),
]

应用程序 url.py:

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.blogIndex, name='blogindex'),
    url(r'^detail/(?P<postid>.+)$', views.blogDetail, name='blogDetail'),
]

错误：

    return check_method()

RecursionError: maximum recursion depth exceeded

views.py：

from django.shortcuts import render, get_object_or_404
from .models import BlogPost

def blogIndex(request):
    blogposts = BlogPost.objects.order_by('-pub_date')
    context = {
        'heading':'The Blog',
        'subheading':'',
        'title':'Blog',
        'copyright':'Pending',
        'blogposts':blogposts,
    }
    return render(request,'blog-home-2.html',context)

def blogDetail(request,postid):
    post = get_object_or_404(BlogPost, pk=postid)
    context = {
        'post' : post,
        'copyright':'Pending',
        }
    return render(request,'blog-post.html',context)

【解决方案1】：

您将项目 URL 包含在自身中，而不是包含您的应用 URL。

【讨论】：

那么如何正确地将应用 URL 包含到项目 URL 中？
如我所说。从您的主项目 urls.py 中，包含您的 app 网址，而不是再次包含项目的网址。
