Django中的Kwargs和基于类的视图

Question

我搜索了SO和Django文档,似乎无法找到它.我正在扩展django.contrib.comments应用程序的基本功能,以使用我的webapp中的自定义权限系统.对于审核操作,我尝试使用基于类的视图来处理对注释和权限检查的基本查询. (在此上下文中的"EComment"是我的"增强评论",继承自基础django评论模型.)

我遇到的问题comment_id是从urls.py中的URL传入的kwarg.如何从基于类的视图中正确检索？

现在,Django正在抛出错误TypeError: ModRestore() takes exactly 1 argument (0 given).代码包括在下面.

urls.py

url(r'restore/(?P<comment_id>.+)/$', ModRestore(), name='ecomments_restore'),

views.py

def ECommentModerationApiView(object):

    def comment_action(self, request, comment):
        """
        Called when the comment is present and the user is allowed to moderate.
        """
        raise NotImplementedError

    def __call__(self, request, comment_id):
        c = get_object_or_404(EComment, id=comment_id)
        if c.can_moderate(request.user):
            comment_action(request, c)
            return HttpResponse()
        else:
            raise PermissionDenied

def ModRestore(ECommentModerationApiView):
    def comment_action(self, request, comment):
        comment.is_removed = False
        comment.save()

您没有使用基于类的视图.你不小心写了def而不是class:

def ECommentModerationApiView(object):
...
def ModRestore(ECommentModerationApiView):

应该是:

class ECommentModerationApiView(object):
...
class ModRestore(ECommentModerationApiView):
