这是一个创建于 4464 天前的主题，其中的信息可能已经有所发展或是发生改变。
最近看到django通用视图部分（http://djangobook.py3k.cn/2.0/chapter11/），做到这一步；
说明我的project名--generic,book-app是generic/generic/book
#model.py，之前例子中Publisher的定义(generic/generic/book/model.py）
class Publisher(models.Model):
name = models.CharField(max_length=30)
address = models.CharField(max_length=50)
city = models.CharField(max_length=60)
state_province = models.CharField(max_length=30)
country = models.CharField(max_length=50)
website = models.URLField()
def __unicode__(self):
return self.name
#urls.py 在generic/generic/urls.py
from django.conf.urls.defaults import *
from django.views.generic import list_detail
from mysite.books.models import Publisher
publisher_info = {
'queryset': Publisher.objects.all(),
'template_name': 'publisher_list_page.html',
}
urlpatterns = patterns('',
url(r'^publishers/$', list_detail.object_list, publisher_info),
)
模板在generic/templates下，generic/templatespublisher_list_page.html
publisher_list_page.html
<h2>Publishers</h2>
<ul>
{% for publisher in object_list %}
<li>{{ publisher.name }}</li>
{% endfor %}
</ul>
浏览器请求ocalhost:8000/publishers，但是页面一直显示：
Page not found (404)
Request Method: GET
Request URL: http://localhost:8000/publishers
Using the URLconf defined in generic.urls, Django tried these URL patterns, in this order:
1.^about/$
2.^publishers/$
The current URL, publishers, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

什么版本的django？我看了我的url.py里面下urlpatterns元祖的元素都是(),(),().....而不是url(),url(),url().......
debug页面都告诉你连这个url都识别不出来了…… |

budong OP 问题已解决：访问时像这样 http://localhost:8000/publishers/在后面加一个/就行了。
但是为什么会是这样，我还在思考中，如果你知道请告诉我。 |

上面没看完。
但只看这条的话。 ^publishers/$ 你尝试改成 ^publishers$ 应该不能达成你第一个要求了。有时间的话，建议把正则的相关的几本书给他啃掉。 不一定要会写得多牛逼，但至少要知道各处修饰符的意义。 |

^publishers/$
建议改成 ^publishers/?$ 就是有无/都可以访问 你要多了解下正则表达式啊.... |
