Question

我的网址是http://127.0.0.1:8000/upload/picturelist/1，这使得user_id = 1，

在我的urls.py中

url(r'^picturelist/(?P<user_id>\d+)$', views.pictureList),

在我的view.py

中

def pictureList(request, user_id):
    if int(user_id) != request.user.id:
        raise PermissionDenied

如何使这个基于函数的视图使用createview？

class pictureList(CreateView):

Answer 1

我从未使用CreateView，但这是我从阅读文档中收集到的内容：

您可以通过定义form_valid：

来实现

查看：

class pictureList(CreateView): model = YourModelHere fields = ['whatever','fields','you','want','edited'] def form_valid(self, form): record = form.save(commit = False) # assuming the user id is associated # to the model with fieldname user_id if (self.request.user == record.user_id): record.save() return HttpResponseRedirect(self.get_success_url()) # not sure if this works: return self.form_invalid()

然后模板将在'yourappname/yourmodelhere_form.html'。

有关示例，请参阅CreateView。

Answer 2

你可以这样做：

在urls.py中：url(r'^picturelist/(?P<user_id>\d+)$', views.MakeItView.as_view()),

在views.py中：

class MakeItView(CreateView):
    model = myModel
    template_name = 'whatever.html'

    def get_context_data(self, **kwargs):
        context = super(MakeItView, self).get_context_data(**kwargs)
        if int(self.kwargs['user_id']) != self.request.user.id:
            raise PermissionDenied
        return context

基于Django函数的视图到基于类的视图
