Python 与自定义django用户模型不一致的MigrationHistory错误

我正在创建一个自定义用户模型

我运行命令

python manage.py makemigrations accounts

，然后运行

python manage.py migrate accounts

，输出以下错误：

Traceback (most recent call last):

以下是应用程序中唯一的迁移文件：

from __future__ import unicode_literals

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


class Migration(migrations.Migration):

    initial = True

    dependencies = [
        ('auth', '0008_alter_user_username_max_length'),
    ]

    operations = [
        migrations.CreateModel(
            name='User',
            fields=[
                ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
                ('password', models.CharField(max_length=128, verbose_name='password')),
                ('last_login', models.DateTimeField(blank=True, null=True, verbose_name='last login')),
                ('is_superuser', models.BooleanField(default=False, help_text='Designates that this user has all permissions without explicitly assigning them.', verbose_name='superuser status')),
                ('email', models.EmailField(max_length=254, unique=True)),
                ('username', models.CharField(max_length=40, unique=True)),
                ('avatar', models.ImageField(blank=True, null=True, upload_to=b'')),
                ('date_joined', models.DateTimeField(default=django.utils.timezone.now)),
                ('is_active', models.BooleanField(default=True)),
                ('is_staff', models.BooleanField(default=False)),
                ('groups', models.ManyToManyField(blank=True, help_text='The groups this user belongs to. A user will get all permissions granted to each of their groups.', related_name='user_set', related_query_name='user', to='auth.Group', verbose_name='groups')),
                ('user_permissions', models.ManyToManyField(blank=True, help_text='Specific permissions for this user.', related_name='user_set', related_query_name='user', to='auth.Permission', verbose_name='user permissions')),
            ],
            options={
                'abstract': False,
            },
        ),
    ]

我以前从未遇到过这个错误，也不知道该如何处理。如何解决此问题？

Django迁移可能依赖于其他Django模型迁移 例如：

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

迁移admin.0001_首字母在其依赖项之前应用 accounts.0001_在数据库“default”上的首字母

您的admin.0001\u initial似乎与accounts.0001\u initial存在依赖关系，并且它已经被迁移。您应该手动修改依赖项。

我在Django中创建新项目时做了完全相同的事情，我要做的是删除数据库并运行python命令

manage.py migrate

。创建了具有新用户表的应用程序的.0001_首字母，执行迁移时，会看到此顺序

如您所见，

admin.0001\u initial

在

subscription.0001\u initial

迁移后执行，这消除了依赖性问题

它只需要包含“AUTH\u USER\u MODEL='app.Account'”在makemigrations&migrate命令后的设置中，似乎您在应用管理迁移后更改了用户模型。请阅读。完美的答案！解决了我的问题！
