数据迁移导致错误 AttributeError: type object 'User' has no attribute 'normalize_username'？

Question

我正在尝试创建数据迁移以将用户添加到数据库。但是，当我尝试这样做时出现属性错误。

我已经运行 ipdb 来解决问题，我尝试注释掉用户对象的字段以查看其中之一是否导致错误，并且我尝试添加“user.save()”

    user.save()
    urec_staff = staffPosition.objects.create(

AttributeError: type object 'User' has no attribute 'normalize_username'

您应该使用create()而不是create_user()，因为 UserManager 在迁移中不起作用。确保以正确的方式生成密码。

from django.contrib.auth.hashers import make_password

def create_urechr_user(apps, schema_editor):
    # ...
    user = User.objects.create(
        username = "myName",
        password = make_password("test"),
        is_active = True,
        email = "",
    )
    # ...
