获取正在更改的用户对象模型 Django Admin

Question

如何检索当前正在使用 Django 管理员更改的用户的模型？

例如你有更改网址：

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“更改密码”时，它会提供当前登录用户的详细信息，而不是被更改用户的详细信息。

更新 2

从下面的响应中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.

但是路径url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'
    title = _('PIN change')
    pk_url_kwarg = 'object_id'
    object = None

    @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.get_object()
        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)

您可以在视图中添加SingleObjectMixin，并使用get_object() 方法获取User 对象。

from django.views.generic.detail import SingleObjectMixin


class PinChangeView(
    SingleObjectMixin,
    ...
):
    model = AuthUser
    pk_url_kwarg = 'object_id'  # because your url param is `object_id`
    object = None


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