from django.conf.urls.defaults import *

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

Answer 1

object_detail视图将queryset作为第一个位置参数。因此，在您的正则表达式中为该URL匹配(\S+)的值将被解释为查询集arg，它与您在POST字典中传递的kwarg冲突。

如果您尝试将object_id作为URL中的匹配元素发送，则需要使用命名组：

url(r'^post/(?P<object_id>\S+)/$' ...

Answer 2

您需要将?:添加到您不希望传递给视图函数的组（括号）中。像这样：

url(r'^post/(?:\S+)/$', 'django.views.generic.list_detail.object_detail', post, name='post'),

object_detail（）获取关键字参数'queryset'的多个值，同时只输入一个
