Django中与webmonkey教程相关的URL模式问题

Question

我正在学习Django的webmonkey教程，现在卡在了第4课，具体内容可以在这里找到：http://www.webmonkey.com/2010/02/Use_Templates_in_Django/。

我遇到的问题是关于博客详情模板的，每当我在我的blog/list.html页面点击链接查看某个条目的详细信息时，都会出现“页面未找到（404）”的错误。

我看到的错误信息是：

Page not found (404)
Request Method:     GET
Request URL:http://127.0.0.1:8000/2010/dec/17/welcome-my-blog/

Using the URLconf defined in djangoblog.urls, Django tried these URL patterns, in this order: 

^admin/(.*) 
^blog/ 
^tags/(?P<slug>[a-zA-Z0-9_.-]+)/$ 
The current URL, 2010/dec/17/welcome-my-blog/, didn't match any of these.

这是我的url.py文件和models.py文件的内容，我没有贴出我的admin、tag视图或设置文件，但如果需要的话我可以提供。

djangoblog\urls.py

# This also imports the include function
from django.conf.urls.defaults import *
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
(r'^admin/(.*)', admin.site.root),
(r'^blog/', include('djangoblog.blog.urls')),
(r'^tags/(?P<slug>[a-zA-Z0-9_.-]+)/$', 'djangoblog.tag_views.tag_detail'),
)

djangoblog\blog\urls.py

from django.conf.urls.defaults import *
from djangoblog.blog.models import Entry
from tagging.views import tagged_object_list

info_dict = {
 'queryset': Entry.objects.filter(status=1),
 'date_field': 'pub_date',
}

urlpatterns = patterns('django.views.generic.date_based',
(r'(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(?P<slug>[-w]+)/$',    
 'object_detail', dict(info_dict, slug_field='slug',template_name='blog/detail.html')),
(r'^(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(?P<slug>[-w]+)/$',  
 'object_detail', dict(info_dict, template_name='blog/list.html')),   
(r'^(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/$',
 'archive_day',dict(info_dict,template_name='blog/list.html')),
(r'^(?P<year>d{4})/(?P<month>[a-z]{3})/$','archive_month', dict(info_dict, template_name='blog/list.html')),
(r'^(?P<year>d{4})/$','archive_year', dict(info_dict, template_name='blog/list.html')),
(r'^$','archive_index', dict(info_dict, template_name='blog/list.html')),
)

djangoblog\blog\models.py。

from django.db import models
from django.contrib.syndication.feeds import Feed
from django.contrib.sitemaps import Sitemap
import markdown
from tagging.fields import TagField
from tagging.models import Tag

class Entry(models.Model):
    title = models.CharField(max_length=200)
    slug = models.SlugField(
        unique_for_date='pub_date',
        help_text='Automatically built from the title.'
    )

    body_html = models.TextField(blank=True)
    body_markdown = models.TextField()
    pub_date = models.DateTimeField('Date published')
    tags = TagField()
    enable_comments = models.BooleanField(default=True)

    PUB_STATUS = (
        (0, 'Draft'),
        (1, 'Published'),
    )

    status = models.IntegerField(choices=PUB_STATUS, default=0)


    class Meta:
        ordering = ('-pub_date',)
        get_latest_by = 'pub_date'
        verbose_name_plural = 'entries'

    def __unicode__(self):
        return u'%s' %(self.title)

    def get_absolute_url(self):
        return "/%s/%s/" %(self.pub_date.strftime("%Y/%b/%d").lower(), self.slug)

    def save(self):
         self.body_html = markdown.markdown(self.body_markdown, safe_mode = False)
         super(Entry, self).save()

    def get_previous_published(self):
        return self.get_previous_by_pub_date(status__exact=1)

    def get_next_published(self):
         return self.get_next_by_pub_date(status__exact=1)

    def get_tags(self):
         return Tag.objects.get_for_object(self)

如果还有其他文件能帮助解决问题，我也可以提供。我的文件结构如下：

文件结构

编辑：（根据Josh的回答中的评论）

在这个地址出现404错误：blog/dec/17/welcome-my-blog/：

^admin/(.*) 
^blog/ (?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(? P<slug>[-w]+)/$ 
^blog/ ^(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(? P<slug>[-w]+)/$ 
^blog/ ^(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/$ 
^blog/ ^(?P<year>d{4})/(?P<month>[a-z]{3})/$ 
^blog/ ^(?P<year>d{4})/$ 
^blog/ 
^$ ^tags/(?P<slug>[a-zA-Z0-9_.-]+)/$ 
The current URL, blog/2010/dec/17/welcome-my-blog/, didn't match any of these.
