使用 urls.py 时出现 TypeError Django

Question

我是初学者，我正在使用 Django 1.8.3 和 Python 2.7.3。我正在尝试运行服务器并收到以下错误：

Traceback:
File "/home/mercurial/internet.django/djangoenv/local/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response

File "/home/mercurial/internet.django/bzi/mailserver/urls.py" in <module>
  5.     url(r'^$', views.domains, name='domains'),

Exception Type: TypeError at /domains
Exception Value: 'function' object has no attribute '__getitem__'

我的项目文件urls.py:

from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^domains/', include('mailserver.urls')),
]

我的应用程序邮件服务器文件 urls.py:

from django.conf.urls import patterns, url, include
from . import views

urlpatterns = patterns[
    url(r'^$', views.domains),
]

我做错了什么？

Answer 1

你不应该有 patterns 这个名字：

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

Answer 2

错误在urls.py，你应该这样写：

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

现在您在 patterns 之后使用方括号“[]” - 这是 python 解释器调用 patterns.__getitem__() 方法的信号，该方法不存在。这就是您收到错误的原因。
