Python 更新数据后，如何在基于类的视图中返回

以下是my views.py函数：

class ProfileUpdateView(UpdateView):
    model = UserProfile
    fields = ['first_name','last_name','username','gender','datetimepicker','p_photo','h_photo','subtitles','political_incline',
            'about_me','birthplace','lives_in','country','province','city','occupation',
            'relationship_status','website','phone_number','religious_belifs','political_incline',
            'facebook','twitter','RSS','dibble','spotify']

url.py

url(r'^updateprofile/(?P<pk>\d+)/$',views.ProfileUpdateView.as_view(success_url='/postlist/')),

url（r'^updateprofile/（？P\d+）/$，views.ProfileUpdateView.as_view（success_url='/postlist/），

在视图中添加一个成功url，如下所示

success_url = reverse_lazy('the_page_required')

如果要转到详图视图，也可以用这种方式定义

def get_success_url(self):
         return reverse('detail_view_url', kwargs={'pk': self.pk})
