django中自定义用户的管理表单

Question

我在django写我的第一个项目。我需要创建几种具有不同字段的用户类型。我创建了与用户1-1关系的Client类，并尝试为它创建管理表单

models.朋友

class Client(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete="CASCADE")
    new_field = models.CharField("New field", max_length=30)

我正在尝试在django admin中创建表单以使用inlided User字段管理客户端实例。

admin.朋友

class UserInline(admin.StackedInline):
    model = User


class ClientAdmin(admin.ModelAdmin):
    class Meta:
        model = Client
        fields = '__all__'


class ExtendedClientAdmin(ClientAdmin):
    inlines = ClientAdmin.inlines + [UserInline]


admin.site.register(Client, ExtendedClientAdmin)

但我得到以下错误：

Performing system checks...

如何使用内联用户字段为客户管理员创建表单？

Answer 1

也许你首先要这样做：

python manage.py makemigrations
python manage.py migrate

为了将更改映射到数据库
