How is migration creation in Django performed to change the database schema?

In Django, the process of creating migrations for database schema changes is performed using the built-in migration system, which tracks changes in models and generates corresponding migration files.

Main steps:

1. Make changes to models (e.g., add a new field, change the field type).
2. Run the command:

django manage.py makemigrations

This command compares the current models with the last migration state and creates a new migration file describing the changes.

3. Apply migrations to the database:

django manage.py migrate

This command executes the SQL commands necessary to change the database schema according to the migrations.

Thus, the migration creation process is automated and allows for safe and sequential modifications to the database structure without manually writing SQL.
