我正在Docker环境中使用以下Docker YAML文件构建Django项目：
django_3.2.4:
build:
context: ./ImageBuild/
dockerfile: Dockerfile_Build_Django
container_name: Django_3.2.4
depends_on:
- Postgres_13.2
environment:
- DJANGO_SUPERUSER_USERNAME=admin
- DJANGO_SUPERUSER_PASSWORD=123456
- DJANGO_SUPERUSER_EMAIL=admin@abc.com
networks:
external_net:
ipv4_address: 192.168.100.22
restart: always
volumes:
- ./IoTSite/:/usr/src/app/
- /etc/localtime:/etc/localtime:ro
command: sh -c "python manage.py makemigrations && python manage.py migrate && python manage.py createsuperuser --noinput --no-input && rsync --daemon && gunicorn"
我创建了一个自定义用户模型，如下所示：(在settings.py中添加了AUTH_User_Model='IoTSite.User'(
class User(AbstractUser):
UserID = models.CharField('username：',help_text='required', max_length=20, primary_key=True,unique=True, blank=False)
USERNAME_FIELD = 'UserID'
First_Name = models.CharField('first_name：',max_length = 2)
Last_Name = models.CharField('last_name：',max_length = 2)
Date_Created = models.DateTimeField(auto_now_add=True, editable=False) #timestamps for creation, hidden from user input
Date_Birth = models.DateField('Birthday：')
Gender_Choice = [
('Male','Male'),
('Female','Female'),
]
Gender = models.CharField('Gender：',choices=Gender_Choice, max_length=1)
当我通过命令docker-compose up运行容器时，它失败了，并出现以下错误：(容器一直在重新启动，我没有机会键入我的选择(

Q1:请问我应该如何修复上述错误
编辑：我查看了源代码，django.contribs.auth.base_user.py
class AbstractBaseUser(models.Model):
password = models.CharField(_('password'), max_length=128)
last_login = models.DateTimeField(_('last login'), blank=True, null=True)
is_active = True
REQUIRED_FIELDS = []
和django.contribs.auth.models.py
class AbstractUser(AbstractBaseUser, PermissionsMixin):
EMAIL_FIELD = 'email'
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = ['email']
Q2:在makemigration期间，在DB中创建表(还不是真正的用户(时，为什么需要字段password的默认值
将自定义Model类名从class User(AbstractUser):更改为class Employee(AbstractUser):可以解决问题。我不知道为什么，也许是因为这一更改避免了Model类名的重复(还有另一个django内置的模型类也被命名为"User(
//django.contrib.auth.models.py
class User(AbstractUser):
