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填充到 django 管理员中。我希望当前用户的用户名填充在它User在 django 管理员中所说的列中。附上截图。

如何使用当前代码正确执行该操作？

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

我很高兴得到任何帮助，干杯

from user_profile.forms import HomeForm

from users.forms import CustomUserCreationForm, CustomUserChangeForm

from user_profile.models import Listing

from users.models import CustomUser

# Register models here.

class UserProfileAdmin(admin.ModelAdmin):

    list_display = ['name', 'address', 'zip_code', 'mobile_number', 'created', 'updated', 'get_username']

    list_filter = ['name', 'zip_code', 'created', 'updated',]

    def get_username(self, obj):

        if obj.user is not None:

            return obj.user.username

        return '-'

    get_username.short_description = 'User'

admin.site.register(Listing, UserProfileAdmin)
