primary key auto increment python django

Create a new model in your Django app's models.py file:

from django.db import models

class YourModelName(models.Model):
    your_field = models.CharField(max_length=100)

Add 'id' as the primary key within the model:

class YourModelName(models.Model):
    id = models.AutoField(primary_key=True)
    your_field = models.CharField(max_length=100)

Run the migration to apply the changes to the database:

python manage.py makemigrations
python manage.py migrate
