Python 迁移admin.0001_首字母在其依赖项app.0001_首字母在数据库'；默认值'；

我正试图在

Django

中为我的项目定制用户模型

My型号.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)

AUTH_USER_MODEL = 'app.myCustomeUser'

在设置.py中：

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)

AUTH_USER_MODEL = 'app.myCustomeUser'

这里的

admin.site.register

也是在

admin.py

中完成的。现在，当我尝试

migrate

或

makemigrations

时，它在终端中显示以下消息：

这是什么意思？我也不想在这个

myCustomeUser

模型中设置

username

和

password

的默认值。另外，请建议我，这是制作

usermodel

的正确方法吗？

在这里，我也尝试在删除完整数据库后进行

迁移，但它不起作用。我如何可以解决这个问题吗？您必须删除并重新生成迁移，只是再次迁移并不能解决问题，因为它被记录在案。这是否回答了您的问题？@iklinac我刚刚运行了
python manage.py migrate admin zero
，
python manage.py migrate auth zero
，
python manage.py migrate contenttypes zero
，
python manage.py migrate sessions zero
删除我的迁移，然后重新
makemigrations
和
migrate
，但问题仍然存在。在这里，我也尝试在删除完整数据库后进行
