没有名为 index 的模块

Question

我遇到了一个错误，提示异常值：没有名为 index 的模块。我在 DjangoPhoneBook 和 phonebook 文件夹里都有 __init__.py 文件。我是 Django 新手，正在按照 djangoproject 网站上的教程学习。我在网上搜索了这个错误，但没有找到解决办法。

这个问题的原因和解决方法是什么呢？

Environment:

Request Method: GET
Request URL: http://localhost:8000/Book/
Django Version: 1.2.3
Python Version: 2.6.6
Installed Applications:
['django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.sites',
 'django.contrib.messages',
 'phonebook',
 'django.contrib.admin']
Installed Middleware:
('django.middleware.common.CommonMiddleware',
 'django.contrib.sessions.middleware.SessionMiddleware',
 'django.middleware.csrf.CsrfViewMiddleware',
 'django.contrib.auth.middleware.AuthenticationMiddleware',

Exception Type: ImportError at /Book/
Exception Value: No module named index

urls.py 的内容是

from django.conf.urls.defaults import *
from django.contrib import admin
admin.autodiscover()
from DjangoPhoneBook.phonebook.views import *

urlpatterns = patterns('',
    (r'^Book/$', include('index'))
    (r'^admin/', include(admin.site.urls)),
)

views.py 的内容是

  from django.http import HttpResponse
  def index(request):
     return HttpResponse("This is a view page")

Answer 1

把你第一行的 include 去掉。 include 是用来添加一个单独的 URL 配置的语法，所以 Python 正在寻找一个叫 index 的 module。

把它改成你视图函数的完整 Python 点路径。

urlpatterns = patterns('',
    (r'^Book/$', 'path.to.my.views.index'), # <-- and add a comma here
    (r'^admin/', include(admin.site.urls)),
)

补充：我注意到你在导入你的视图函数。你也可以直接指定视图函数本身。

urlpatterns = patterns('',
    (r'^Book/$', index),
    (r'^admin/', include(admin.site.urls)),
)
