Question

嗨，我有一个django模型，如下所示：

from django.db import models

class ClientProfile(models.Model):
    id = models.AutoField(primary_key=True)
    firstname = models.CharField(max_length=100,blank=False)
    lastname = models.CharField(max_length=100,blank=False)
    gender = models.CharField(max_length=6,blank=False)
    birthdate = models.DateField(blank=False)
    nationality = models.CharField(max_length=100,blank=False)
    education = models.CharField(max_length=100,blank=True)
    occupation = models.CharField(max_length=100,blank=True)

我最初使用电子邮件字段创建了此模型。但是后来我决定扣除它。现在，我在迁移时收到此错误：

django.db.utils.OperationalError: near "AUTOINCREMENT": syntax error

，然后我删除了数据库并再次迁移，并且再次收到相同的消息。我尝试删除我的应用程序视图，然后从头开始（创建新迁移并创建新的超级用户，然后再次添加模型），但仍然遇到相同的错误。我什至尝试回滚到初始迁移，然后再次迁移，但又重新获得了电子邮件字段，新的迁移并没有改变它。我该怎么办？

这些是我的迁移：

这是我的堆栈跟踪：

The above exception was the direct cause of the following exception:

Answer 1

尝试不使用id = models.AutoField(primary_key=True)，这是多余的，因为如果您未指定其他主键，Django会自动分配一个名为id的主键。

如果仍然失败，请显示迁移文件中的代码。

为什么Django不迁移我修改过的模型？
