Django.db.migrations.exceptions.InconsistentMigrationHistory:迁移在其依赖项帐户之前应用。0001_在数据库“default”上初始化

Question

我正在尝试迁移我的自定义用户模型，并运行makemigrations命令对新模型进行迁移。但当我运行migrate命令时，它会抛出以下错误：

django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency accounts.0001_initial on database 'default'.

回溯：

'default'.

型号.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)

我刚才在这个问题中提到了用户模型，但如果需要更多的代码，请告诉我，我将用这些信息更新我的问题。多谢各位

Answer 1

如果您使用的是git之类的版本控制工具，只需恢复迁移中的更改即可。但如果没有，您可以清除迁移历史，如here所述

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。 然后找到0001迁移的id并按如下方式删除：delete from django_migrations where id=<some_id>;，其中some_id是迁移id

Answer 2

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