object_detail() 获得关键字参数“queryset”的多个值；当只输入一个时

object_detail视图将queryset作为第一个位置参数。因此，与该 url 的正则表达式中的(\S+)匹配的值将被解释为 queryset arg，这与您在 POST 字典中传递的 kwarg 相冲突。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：
The
object_detailview hasquerysetas the first positional argument. So the value that matches(\S+)in your regex for that url is being interpreted as the queryset arg, which is conflicting with the kwarg you are passing in the POST dictionary.If you're trying to send the object_id as the matching element in the URL, you'll need to use a named group:
您需要将
?:添加到您不想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'),看这个文章了解更多信息：

You need to add
?:to the groups (parentheses) that you don't want to be passed on to the view function.Like this:
url(r'^post/(?:\S+)/$', 'django.views.generic.list_detail.object_detail', post, name='post'),See this article for more info:
