Python Django-表单提交后无法在管理员中检索用户名

我有一个表单，当用户提交表单时，我需要当前登录的用户自动填充到django管理员中。我希望当前用户的用户名填充在django admin中显示为

user

的列中。附上截图

如何使用当前代码正确执行该操作

我使用的自定义用户模型位于来自用户的

中。如果有帮助，模型将导入CustomUser

我非常感谢你的帮助，干杯

用户配置文件/admin.py 用户_profile/views.py 用户配置文件/forms.py html

---

我想你只需要在

admin.py

注册你的用户模型。。 像

admin.site.register（CustomUser）

---

希望对您有所帮助。

免责声明：我不确定您的代码是否正确。如果工作正常，这也可以：）

def change_视图（请求）：
表单=家庭表单（request.POST或None）
用户_profile=Listing.objects.all
user=request.user
如果form.is_有效（）：
listing_instance=form.save（）#“这将返回'listing'实例”
清单_instance.user=user#分配“user”实例
清单_instance.save（）#调用模型的“save（）”方法
form=HomeForm（）
上下文={
“表单”：表单，“用户配置文件”：用户配置文件
}
return render（请求“myaccount.html”，context）

感谢您的快速响应，我添加了我收到的

django.contrib.admin.sites.AlreadyRegistered:model CustomUser已经注册了

我是不是遗漏了什么？在

admin.site.unregister（CustomUser）

之前执行

admin.site.register（CustomUser）

感谢您的快速响应，我补充说我收到了

django.contrib.admin.sites.AlreadyRegistered:model CustomUser已经注册了

我是不是遗漏了什么？在

admin.site.unregister（CustomUser）

之前执行

admin.site.register（CustomUser）

完美。谢谢你，我的朋友！完美的谢谢你，我的朋友！
