What are Django migrations and how do I use them?

Django migrations are a way to propagate changes you make to your models (like adding a field) into your database schema. You can create migrations using the command python manage.py makemigrations and apply them with python manage.py migrate.

Can you explain how to create a migration for a new model?

Sure! First, define your new model in the models.py file. Then, run python manage.py makemigrations to create a migration file. Finally, apply it with python manage.py migrate.

What if I want to roll back a migration?

You can roll back a migration using the command python manage.py migrate <app_name> <migration_name>. This will revert your database to the state it was in after that migration.

Are there any best practices for managing migrations?

Yes! It's best to keep your migrations organized, avoid large migrations, and regularly check for any conflicts when working in teams.
