我是Django的新手，我的版本是4.1。我在pgAdmin4中更改id列的字段类型时遇到了问题。但是我通过在midel.uuidfield中使用id进行迁移来覆盖ID，如下所示：

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

class Profile(AbstractBaseUser):
    # id = None 
    id = models.UUIDField(unique=True, editable=False, primary_key=True,      verbose_name='ID')
    password = None

当我运行makegrations并在迁移之前将id从None更改为models.uuidfield时，这终于起作用了。现在，该列和添加的其他列都没有反映在数据库中，即PgAdmin4中。
我尝试通过添加一个新列created_time来进行故障排除，如下所示：

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

class Profile(AbstractBaseUser):
    # id = None 
    id = models.UUIDField(unique=True, editable=False, primary_key=True, verbose_name='ID')
    password = None
    created_time = models.DateTimeField(auto_now_add=True)

现在，在运行makemigrations和migrate之后，添加到数据库中的唯一记录是created_time。所以我检查了migrations文件夹，在我的0001_initial.py file中，它看起来像这样：

# Generated by Django 4.1.7 on 2023-04-04 07:11

from django.db import migrations, models

class Migration(migrations.Migration):

    initial = True

    dependencies = [
    ]

    operations = [
        migrations.CreateModel(
            name='Profile',
            fields=[
                ('last_login', models.DateTimeField(blank=True, null=True, verbose_name='last login')),
                ('id', models.UUIDField(editable=False, primary_key=True, serialize=False, unique=True, verbose_name='ID')),
                ('firstname', models.CharField(blank=True, max_length=200, null=True, verbose_name='the first name of a user')),
                ('lastname', models.CharField(blank=True, max_length=200, null=True, verbose_name='the last name of a user')),
                ('display_pic', models.ImageField(blank=True, default='images/avatar.jpg', null=True, upload_to='photo/%Y/%m/%d', verbose_name='profile picture')),
                ('username', models.CharField(blank=True, max_length=200, null=True, unique=True, verbose_name='username')),
                ('email', models.CharField(blank=True, max_length=250, null=True, unique=True, verbose_name='email')),
                ('bio', models.TextField(blank=True, null=True, verbose_name='bio of user')),
                ('is_email_verified', models.BooleanField(default=False, help_text="this designates if the user' email is verified")),
                ('is_active', models.BooleanField(default=True, help_text='this designates if the user is active')),
                ('is_staff', models.BooleanField(default=False, help_text='this designates if the user is staff or not')),
            ],
            options={
                'unique_together': {('id', 'email', 'username')},
            },
        ),
    ]

但是在我添加了created_time字段之后，新的迁移文件是这样的：

# Generated by Django 4.1.7 on 2023-04-04 07:19

from django.db import migrations, models
import django.utils.timezone

class Migration(migrations.Migration):

    dependencies = [
        ('subscribers', '0001_initial'),
    ]

    operations = [
        migrations.AddField(
            model_name='profile',
            name='created_time',
            field=models.DateTimeField(auto_now_add=True, default=django.utils.timezone.now),
            preserve_default=False,
        ),
    ]

很明显，最初的迁移没有应用任何更改。
有人能帮我解决吗？
