Why Django doesnt migrate my altered model?

Question

Hi i have a django model as below:

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)

i have created this model with email field initially. but then i decided to deduct it. now i get this error when i migrate:

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

and then i deleted my database and migrated again and i get the same message again. I tried deleting my app view and then start from scrach(creating a new migration and creating a new superuser and then add the model again) and still got the same error. i even tried rollback to initial migrations and then migrate again but got the email field back again and the new migration didn't change it. what can i do?

and these are my migrations:

and this is my stacktrace:

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

Answer 1

Try without id = models.AutoField(primary_key=True), which is redundant as Django automatically assigns a primary key named id if you don't specify a different primary key.

If it still fails, show the code from the migration file.
