In Django, database migrations are handled using Django’s migration framework, which allows changes to the database schema without manually altering the database. Migrations track model changes, such as adding or modifying fields, and apply them systematically. When a model is created or updated, running python manage.py makemigrations generates migration files that describe the changes. To apply these changes to the database, the command python manage.py migrate is executed, updating the schema accordingly. Migrations ensure that database structure stays in sync with model definitions across development, staging, and production environments. Django also provides python manage.py showmigrations to check applied migrations and python manage.py sqlmigrate <app_name> <migration_number> to view the SQL commands behind a migration. If issues arise, python manage.py migrate --fake can be used to mark migrations as applied without executing them. This system ensures a smooth, version-controlled database management process while maintaining data integrity.
