python - 迁移 admin.0001_initial 在其依赖 app.0001_initial 之前应用在数据库“默认”上

问题描述

我正在尝试为我的项目制作定制的用户模型Django。

我的模型.py：

class myCustomeUser(AbstractUser):
    id = models.AutoField(primary_key=True)
    username = models.CharField(max_length=20, unique="True", blank=False)
    password = models.CharField(max_length=20, blank=False)
    is_Employee = models.BooleanField(default=False)
    is_Inspector = models.BooleanField(default=False)
    is_Industry = models.BooleanField(default=False)
    is_Admin = models.BooleanField(default=False)


class Industry(models.Model):
    user = models.OneToOneField(myCustomeUser, on_delete=models.CASCADE, primary_key=True, related_name='industry_releted_user')
    name = models.CharField(max_length=200, blank=True)
    owner = models.CharField(max_length=200, blank=True)
    license = models.IntegerField(null=True, unique=True)
    industry_extrafield = models.TextField(blank=True)


class Employee(models.Model):
    user = models.OneToOneField(myCustomeUser, on_delete=models.CASCADE, primary_key=True, related_name='employee_releted_user')
    industry = models.OneToOneField(Industry, on_delete=models.CASCADE, related_name='employee_releted_industry')
    i_id = models.IntegerField(null=True, blank=False, unique=True)
    name = models.CharField(max_length=200, blank=False, null=True)
    gmail = models.EmailField(null=True, blank=False, unique=True)
    rank = models.CharField(max_length=20, blank=False, null=True)
    employee_varified = models.BooleanField(default=False)


class Inspector(models.Model):
    user = models.OneToOneField(myCustomeUser, on_delete=models.CASCADE, primary_key=True, related_name='inspector_releted_user')
    inspector_extrafield = models.TextField(blank=True)


class Admin(models.Model):
    user = models.OneToOneField(myCustomeUser, on_delete=models.CASCADE, primary_key=True, related_name='admin_releted_user')
    admin_extrafield = models.TextField(blank=True)

在settings.py 中：

AUTH_USER_MODEL = 'app.myCustomeUser'

这里admin.site.register也是在admin.py. 现在它在我尝试migrateor时在终端中显示以下消息makemigrations：

Traceback (most recent call last):
  File "manage.py", line 21, in <module>
    main()
  File "manage.py", line 17, in main
    execute_from_command_line(sys.argv)
  File "G:\Python\lib\site-packages\django\core\management\__init__.py", line 401, in execute_from_command_line   
    utility.execute()
  File "G:\Python\lib\site-packages\django\core\management\__init__.py", line 395, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "G:\Python\lib\site-packages\django\core\management\base.py", line 328, in run_from_argv
    self.execute(*args, **cmd_options)
  File "G:\Python\lib\site-packages\django\core\management\base.py", line 369, in execute
    output = self.handle(*args, **options)
  File "G:\Python\lib\site-packages\django\core\management\base.py", line 83, in wrapped
    res = handle_func(*args, **kwargs)
  File "G:\Python\lib\site-packages\django\core\management\commands\makemigrations.py", line 101, in handle       
    loader.check_consistent_history(connection)
  File "G:\Python\lib\site-packages\django\db\migrations\loader.py", line 295, in check_consistent_history        
    raise InconsistentMigrationHistory(
django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency app.0001_initial on database 'default'.

这是什么意思？而且我也不想在这个模型中设置username&的默认值。还请建议我，这是正确的制作方法吗？passwordmyCustomeUserusermodel

解决方案

我也有同样的问题，但我只是从每个应用程序中删除了我的迁移，删除了数据库，并创建了一个新的。并使用`

python manage.py makemigrations python manage.py migrate

进行新的迁移，一切正常。
