Question

您好我收到此错误：/ sss / edit /中的KeyError 'PK' 我知道keyError意味着dict中没有键。但我不明白为什么它会给我。它看起来很简单，但我得到了这个错误。这是我的代码

class PostUpdateView(UpdateView):
     model = Post
     form_class = PostForm
     template_name = 'main/edit.html'

     def form_valid(self, form):
            self.object = form.save(commit=False)
            # Any manual settings go here
            self.object.save()
            return HttpResponseRedirect(self.object.get_absolute_url())

     @method_decorator(login_required)
     def dispatch(self, request, *args, **kwargs):
        post = Post.objects.get(pk=kwargs['pk'])
        if request.user.has_perm('main.change_post') and post.created_by == request.user:
            return super(PostUpdateView, self).dispatch(request, *args, **kwargs)
        else:
            return http.HttpForbidden()

我从post=Post.objects.get(pk=kwargs['pk'])

收到错误

我也有这个模型

class Post(models.Model):
    pub_date = models.DateTimeField(auto_now_add = True)

先谢谢

如果您在urls.py中定义了pk，则只能访问url(r'^sss/edit/(?P<pk>\d+)$', PostUpdateView.as_view())：

<Button></Button>

/ sss / edit /'pk'中的KeyError
