How do I add new fields to an existing Django model using migrations?

To add new fields to an existing Django model, you need to create a new migration. You can do this by running the command python manage.py makemigrations after modifying your model.

What if I want to set a default value for the new field?

You can set a default value by specifying it in the model field definition. For example, new_field = models.CharField(default='default_value', max_length=100).

Do I need to run any commands after creating the migration?

Yes, after creating the migration, you need to apply it by running python manage.py migrate.

Can I add multiple fields at once?

Absolutely! You can add multiple fields in the same migration by defining them in your model and then running makemigrations.
