'method'对象不支持项目分配

Question

我试着计算每个帖子的点赞数，这是我的模型。但是我在项目详细信息页面上得到错误

likes = models.ManyToManyField(User, related_name='blog_posts')

def total_likes(self):
return self.likes.count()

视图:

class ItemDetailView(DetailView):
model = Item
template_name ='waqart/item_detail.html'

def get_context_data(self, *args, **kwargs):
context = super(ItemDetailView, self).get_context_data
stuff = get_object_or_404(Item, id=self.kwargs['pk'])
total_likes = stuff.total_likes()
context['total_likes']= total_likes
return context

Answer 1

您忘记呼叫get_context_data了。改为:

context = super(ItemDetailView, self).get_context_data(*args, **kwargs)
