我正在尝试使用高级用户 models.py 更新我的项目中的迁移
class Teacher(AbstractUser):
name = models.CharField(max_length=20, unique=False)
surname = models.CharField(max_length=20)
email = models.EmailField(max_length=255, unique=True)
USERNAME_FIELD = 'email'
user = models.OneToOneField(settings.AUTH_USER_MODEL, null=True,
on_delete=models.CASCADE)
subject = models.ForeignKey(Subject, related_name='teacher_subject',
null=True, on_delete=models.CASCADE)
password = models.CharField(max_length=50)
REQUIRED_FIELDS = ['name', 'surname', 'password']
什么可能导致这样的错误？最初，这个问题出在 Teacher.username 上，我在 Google 上搜索到你需要添加 USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['name', 'surname', 'password'] 但显然它并没有好转

add_form = TeacherRegistrationForm
form = TeacherChangeForm
model = Teacher
list_display = ['name','surname','subject']
admin.site.register(Teacher, TeacherUserAdmin)
当我尝试创建迁移时，我得到了错误

我需要添加一个指向我的 Django 站点的链接，该链接仅在用户在特定组中时才会出现。我试图写一个解决方案，但它引发了一堆错误
