从其他表单 django admin 获取字段的值

Question

简单地说，我想在 django admin 中的用户（管理员）之间构建一个小型电子邮件应用程序我成功地让用户发送和接收消息，在下一步中：用户应该能够回复收到的消息。只是我在 index 表单中添加了一个 "Reply" 按钮以将其重定向到发件箱表单，现在的问题是如何在请求中添加 to:mail？

我的model.py

class Mail(models.Model):
from_user = models.ForeignKey(settings.AUTH_USER_MODEL,
                              verbose_name=_('From User'),
                              related_name='sent_mails')
to_user = models.ForeignKey(settings.AUTH_USER_MODEL,
                            verbose_name=_('To User'),
                            related_name='recieved_mails')
subject = models.CharField(_('Subject'), max_length=255)
body = models.TextField(_('Body'))
read = models.BooleanField(default=False)

created_at = models.DateTimeField(auto_now_add=True)
last_update = models.DateTimeField(auto_now=True)

admin.py

class Inbox(Mail):

     class Meta:
         app_label = 'internal_mails'
         proxy = True
         verbose_name = _("Inbox")
         verbose_name_plural = _("Inbox")


class Outbox(Mail):

    class Meta:
        app_label = 'internal_mails'
        proxy = True
        verbose_name = _("Outbox")
        verbose_name_plural = _("Outbox")

class InboxAdmin(MailAdmin):
    list_display = ('id', 'from_user', 'subject',)
    exclude = ('read',)

    def get_queryset(self, request):
       queryset = super(InboxAdmin, self).get_queryset(request)
       return queryset.filter(to_user=request.user)

    def has_add_permission(self, request, obj=None):
        return False

    def changeform_view(self, request, object_id=None, form_url='', extra_context=None):
        response = super(InboxAdmin, self).changeform_view(
            request, object_id=object_id,
            form_url=form_url, extra_context=extra_context
        )
        if isinstance(response, HttpResponseRedirect):
            obj = Mail.objects.get(id=object_id)
            print(obj.from_user)
            response = HttpResponseRedirect('/'.join(response.url.split('/')[:-2] + ['outbox/add/']))
        else:
           obj = Inbox.objects.get(id=object_id)
           obj.read = True
           obj.save()
        return response


class OutboxAdmin(MailAdmin):
    list_display = ('id', 'to_user', 'subject',)
    list_filter = ('to_user',)
    exclude = ('from_user', 'read',)

    def get_queryset(self, request):
        queryset = super(OutboxAdmin, self).get_queryset(request)
        return queryset.filter(from_user=request.user)

    def save_model(self, request, obj, form, change):
        obj.from_user = request.user
        obj.save()


admin.site.register(Inbox, InboxAdmin)
admin.site.register(Outbox, OutboxAdmin)

Answer 1

以下是我如何解决我在 url 中发送用户 ID 的问题例如： 127.0.0.1:8000/en/outbox/add/?to_user=1

当点击回复按钮时，它会重定向到用户 ID 为

的发件箱

在 InboxAdmin class

    if isinstance(response, HttpResponseRedirect):
        obj = Mail.objects.get(id=object_id)
        url = reverse("admin:internal_mails_outbox_add")
        return HttpResponseRedirect(url + "?to_user=" + str(obj.from_user.id))

附加说明如果你需要知道如何在 Django-admin 中反转 URL 你可能需要阅读这个 https://docs.djangoproject.com/en/dev/ref/contrib/admin/#reversing-admin-urls
