How do I perform data migrations in Django?
In Django, data migrations allow you to manipulate data in your database during schema changes. You can create a data migration using the makemigrations command with the --empty flag.
Can you give me an example of a data migration?
Sure! First, create an empty migration: python manage.py makemigrations your_app --empty. Then, edit the migration file to include your data manipulation logic in the operations list.
What kind of data manipulations can I perform?
You can perform various operations like updating fields, creating new records, or deleting existing ones using RunPython in your migration.
How do I test my data migration?
You can test your data migration by running python manage.py migrate --fake to simulate the migration without applying it, and then check your database state.
