Django-提交表单后无法在管理员中检索用户名

Question

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在django管理员中填充。我希望当前用户的用户名填充在django管理员中显示User的列中。截图。

如何使用当前代码正确执行该操作？

如果有帮助，我正在使用的自定义用户模型位于from users.models import CustomUser中。

我很感激任何帮助，干杯

免责声明：我不确定您的代码是否正确。如果一切正常，也可以:)

def change_view(request):
    form = HomeForm(request.POST or None)
    user_profile = Listing.objects.all
    user = request.user

    if form.is_valid():
        listing_instance = form.save()  # "this will return the 'Listing' instance"
        listing_instance.user = user # assign 'user' instance
        listing_instance.save() # calling 'save()' method of model
        form = HomeForm()

    context = {
        'form': form, 'user_profile': user_profile
    }

    return render(request, "myaccount.html", context)

我认为您只需要dataSrc: function (json) { var jsonData = JSON.parse(json); return jsonData.data; } 的{​​{1}}用户模型即可。 喜欢..
