学习

*The Django Book: **第**9章 Generic views*

*列表/细节generic views *
写了一些代码 这是urls.py的内容：

from django.conf.urls.defaults import *
from django.views.generic import list_detail
from bookstore.models import Author,Publisher,Book

author_list_info={'queryset':Author.objects.all()}

urlpatterns = patterns('',
    # Example:
    # (r'^mysite/', include('mysite.foo.urls')),
     (r'^authors/$',list_detail,dict(author_list_info)),

    # Uncomment this for admin:
     (r'^admin/', include('django.contrib.admin.urls')),
)

错误如下:

 AttributeError at /authors/ 'module' object has no attribute 'rindex'  Request
