错误地从我的模型中删除了id字段

Question

我不小心从模型中删除了id字段。现在我要撤消它。我收到完整性错误 - 数据类型不匹配错误。

但python manage.py makemigrations和python manage.py migrate运行良好，没有任何问题。我也删除了模型并再次创建它。创建后，在迁移模型时创建的0001_initial.py文件包含默认的id列。但我仍然无法解决我的问题。

完整的错误跟踪如下：

    sqlite3.IntegrityError: datatype mismatch

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

修改

这是models.py文件。

from django.db import models
from django import forms
from django.forms import ModelForm
class createEvent(models.Model):
    FirstName = models.CharField(max_length=100)
    LastName = models.CharField(max_length=100)
    EventName = models.CharField(max_length=150)
    EventOrganizer = models.CharField(max_length=150)
    Location = models.CharField(max_length=200)
    Date = models.DateField()
    LastDateOfRegistration = models.DateField()
    EventDetails = models.TextField()
