What are some effective strategies for Django migrations?

There are several strategies for managing Django migrations effectively, such as using squashed migrations, keeping migrations small, and testing migrations in a staging environment.

Can you explain what squashed migrations are?

Squashed migrations combine multiple migrations into a single one, which helps reduce the number of migration files and can improve performance.

How do I create a squashed migration?

You can create a squashed migration using the command python manage.py squashmigrations <app_name> <migration_name>. This will combine the specified migrations.

What should I do if a migration fails?

If a migration fails, you can roll back the migration using python manage.py migrate <app_name> <previous_migration>, fix the issue, and then try migrating again.
