'QuerySet' 对象不支持项目分配

'QuerySet' object does not support item assignment

class PostDetailView(DetailView):
    model = Post
    template_name = 'detail.html'

    def get_context_data(self, **kwargs):
        context = super(PostDetailView, self).get_context_data(**kwargs)
        instance = Post.objects.get(pk=self.kwargs.get('pk'))
        user = instance.post_user
        context['comments'] = Comment.objects.filter(comment_post=instance.pk)
        context['comments']['profile'] = Profile.objects.get(user=user)
        return context

这是我目前的看法。当我使用该代码时,出现此错误 'QuerySet' object does not support item assignment。如何正确附加下面的行?

context['comments']['profile'] = Profile.objects.get(user=user)

问题是 context['comments'] 的值不是字典而是 QuerySet 对象。
所以你不能这样做:
context['comments']['profile'] = Profile.objects.get(user=user).

也许您可以将与 Profile 模型的关系添加到 Comment 模型中,例如:

class Comment(models.Model):
    profile = models.ForeignKey(Profile, ...)
    ...

这样您就可以访问发表评论的个人资料的值。
