【问题描述】：

我正在尝试迁移我的自定义用户模型并运行makemigrations 命令来迁移新模型。但是当我运行 migrate 命令时，它会抛出这个错误：

django.db.migrations.exceptions.InconsistentMigrationHistory：迁移 admin.0001_initial 在其依赖项 accounts.0001_initial 之前应用于数据库“默认”。

追溯：

models.py

class User(auth.models.AbstractUser):

    current_balance = models.IntegerField(("current balance"),default=0,blank=True)
    age = models.IntegerField(("age"),null=True)
    gender = models.CharField(("gender"), max_length=50,choices=GENDER_CHOICES,null=True)
    nationality = models.CharField(("nationality"), max_length=50,null=True)


    def __str__(self):
        return "@{}".format(self.username)

我刚刚在这个问题中提到了用户模型，但如果需要更多代码，请告诉我，我将使用该信息更新我的问题。谢谢

【解决方案1】：

如果您使用的是 git 等版本控制工具，只需还原迁移中的更改。但如果没有，您可以按照here 的说明清除迁移历史记录。

它建议使用python manage.py dbshell 连接到数据库，然后使用select * from django_migrations where app='admin'; 查看迁移历史记录。然后找到 0001 迁移的 id 并像这样删除：delete from django_migrations where id=<some_id>; 其中some_id 是迁移 id。

【解决方案2】：

删除所有迁移文件夹。也删除db.sqlite3，然后运行python manage.py makemigrations 和 python manage.py migrate
