To squash migrations in Django, you can use the squashmigrations management command. This command combines multiple migration files into a single file, making your database schema more concise and reducing the size of your migration history.
Here’s how you can use the squashmigrations command:
First, make sure all of your migrations have been applied to your database.
Run the following command:
python manage.py squashmigrations
The command will generate a new migration file with the squashed operations.
Apply the new migration using the following command:
python manage.py migrate
Note: Before squashing migrations, make sure you backup your database, as this process is irreversible. Also, be aware that squashing migrations can cause issues with third-party apps, so make sure to test the squashed migrations thoroughly in a test environment before applying to a production environment.
