In Django, how can you add a column to an existing model’s database table?

Define a new model and migrate the changes using Django's makemigrations and migrate commands.
Use the add_column method provided by the Django models module.
Use the ALTER TABLE SQL command directly on the database.
You cannot add a column to an existing model in Django.

In Django, you define a new model field within the existing model, then create a migration using makemigrations and apply it using migrate to add a new column to the database table associated with the model. Direct SQL commands should be avoided to maintain consistency and manageability.
