【问题描述】：

我刚刚建立了一个django项目，报错：

Request Method: GET
Request URL:    http://127.0.0.1/hello/
Django Version: 1.6.6
Exception Type: ImproperlyConfigured
Exception Value:    
The included urlconf <function hello at 0x7f665a1e0320> doesn't have any patterns in it
Exception Location: /usr/local/lib/python2.7/dist-packages/django/core/urlresolvers.py in url_patterns, line 369
Python Executable:  /usr/local/bin/uwsgi
Python Version: 2.7.6

urls.py:

from django.conf.urls import patterns, include, url
import testsite.views
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^hello/', include(testsite.views.hello)),
)

views.py：

from django.http import HttpResponse

def hello(request):
    return HttpResponse("Hello, world!")

settings.py：

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))

我在谷歌上搜索过设置 DEBUG_TOOLBAR_PATCH_SETTINGS = False，但没有帮助。有什么问题以及如何解决？

标签： django django-urls

【解决方案1】：

错误很明显：它不是有效的 url 配置。

要纠正问题，您可以这样做：

# app/views.py
from django.http import HttpResponse

def hello(request):
    return HttpResponse("Hello, world!")

现在在该应用中创建一个名为 urls.py 的文件：

# app/urls.py
from django.conf.urls import url

from app import views

urlpatterns = [
    url(r'^$', views.hello, name='hello'),
]

现在终于在site/urls.py:

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

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

【解决方案2】：

不要将include() 用于视图模式：

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^hello/', testsite.views.hello),
)

include() 用于从另一个模块/应用程序就地“包含”url 配置。
