Python Django 导入错误

Question

我刚接触Django，正在用Python 2.6和Django 1.3版本来创建一个简单的博客应用。当我访问 http://127.0.0.1:8000/admin/ 时，出现了一个错误，提示 No module named urls。我在urls.py文件里写了这行代码： url(r'^admin/', include('django.contrib.admin.urls'))。

urls.py

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

# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'mysite.views.home', name='home'),
    # url(r'^mysite/', include('mysite.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
     url(r'^admin/', include('django.contrib.admin.urls')),
)

settings.py

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'mysite.blog',
    #Uncomment the next line to enable the admin:
    'django.contrib.admin',
    # Uncomment the next line to enable admin documentatio    n:  
    'django.contrib.admindocs',
 )

models.py

   from django.db import models
   from django.contrib import admin

   class BlogPost(models.Model):
     title=models.CharField(max_length=150)
     body=models.TextField()
     timestamp=models.DateTimeField()

   admin.site.register(BlogPost)

错误信息：

有没有什么建议？

Answer 1

你有没有在你的settings.py文件中的INSTALLED_APPS列表里启用django.contrib.admin？

Django只有在你把Python模块（在Django里也叫“Django应用”）写在settings.py文件的INSTALLED_APPS列表里时，才会知道它们的存在。

谢谢你。之前的代码缩进不正确。我已经修好了。
