获取正在更改的用户对象模型 Django Admin

您如何使用 Django 管理员检索当前正在更改的用户模型？

例如，您有更改网址：

https://www.example.com/admin/users/2/change

我需要 ID 为 2 的用户模型，而不是通过执行找到的当前登录用户

self.request.user

编辑请注意，这是用于我使用 PasswordChangeView 实现的自定义密码更改视图：

class PinChangeView(PasswordContextMixin, FormView):
    form_class = SetPinForm
    model = AuthUser
    template_name = 'pin_change_form.html'
    title = _('PIN change')


    @method_decorator(sensitive_post_parameters())
    @method_decorator(csrf_protect)
    @method_decorator(login_required)
    def dispatch(self, *args, **kwargs):
        return super().dispatch(*args, **kwargs)


    def get_form_kwargs(self):
        kwargs = super().get_form_kwargs()
        kwargs['user'] = self.request.user
        return kwargs


    def get_context_data(self, **kwargs):
        data = super().get_context_data(**kwargs)
        data = {
            'opts': self.model._meta,
            'original': self.request.user,
            'form': self.get_form(self.get_form_class()),
        }
        return data


    def get_success_url(self):
        return reverse_lazy('admin:users_authuser_change', kwargs={'object_id': self.request.user.id})


    def form_valid(self, form):
        form.save()
        messages.add_message(self.request, messages.SUCCESS, _('PIN number updated'))
        return super().form_valid(form)

当我使用“pin change”时，它会提供当前登录用户的详细信息，而不是正在更改的用户的详细信息。

从下面的响应进行更改我收到错误：

AttributeError at /admin/users/authuser/2/pin_number/
Generic detail view PinChangeView must be called with either an object pk or a slug in the URLconf.

但路径网址是：

path('<pk>/pin_number/', PinChangeView.as_view(), name='pin_change'),

当前 PinChangeView 代码

class PinChangeView(PasswordContextMixin, SingleObjectMixin, FormView):
    form_class = SetPinForm
    model = AuthUser
    template_name = 'pin_change_form.html'
