如何在 django 用户 model 中生成随机唯一用户 ID 值并将其显示在 django 管理员上？

Question

I have a Model in Django. I just extended the AbstractBaseUser and added some custom fields in the with BaseUserManager.

Now I need to generate a unique Id as primary key and need to show it on Django admin. How can I do that? My model is given below.

from django.db import models
from django.contrib.auth.models import AbstractBaseUser,PermissionsMixin,BaseUserManager



class CustomUserManager(BaseUserManager):
    def _create_user(self, email, password, first_name, last_name, mobile, **extra_fields):
        if not email:
            raise ValueError("Email must be provided")
        if not password:
            raise ValueError('Password is not provided')

        user = self.model(
            email = self.normalize_email(email),
            first_name = first_name,
            last_name = last_name,
            mobile = mobile,
            **extra_fields
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_user(self, email, password, first_name, last_name, mobile, **extra_fields):
        extra_fields.setdefault('is_staff',True)
        extra_fields.setdefault('is_active',True)
        extra_fields.setdefault('is_superuser',False)
        return self._create_user(email, password, first_name, last_name, mobile, password, 
**extra_fields)

    def create_superuser(self, email, password, first_name, last_name, mobile, 
**extra_fields):
        extra_fields.setdefault('is_staff',True)
        extra_fields.setdefault('is_active',True)
        extra_fields.setdefault('is_superuser',True)
        return self._create_user(email, password, first_name, last_name, mobile, 
 **extra_fields)


class User(AbstractBaseUser,PermissionsMixin):
    
    email = models.EmailField(db_index=True, unique=True, max_length=254)
    first_name = models.CharField(max_length=240)
    last_name = models.CharField(max_length=255)
    mobile = models.CharField(max_length=50)
    address = models.CharField( max_length=250)

    is_staff = models.BooleanField(default=True) 
    is_active = models.BooleanField(default=True) 
    is_superuser = models.BooleanField(default=False) 

    objects = CustomUserManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['first_name','last_name','mobile']

    class Meta:
        verbose_name = 'User'
        verbose_name_plural = 'Users'

If you've set DEFAULT_AUTO_FIELD inside your settings.py then you don't have to set primary key for your User model django will add it automaticaly you can read about it primary_key but if you're willing to add custom id's to your User model then you can use UUIDField like this

import uuid
from django.db import models
from django.contrib.auth.models import AbstractBaseUser,PermissionsMixin

class User(AbstractBaseUser,PermissionsMixin):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    # other fields
