What is the structure of Django ORM migrations?

Django ORM migrations consist of a series of files that define changes to your database schema. Each migration file includes operations like creating or modifying models, fields, and relationships.

Can you explain what a migration file looks like?

Sure! A migration file typically contains a class that inherits from migrations.Migration. It includes attributes like dependencies and operations, where operations define the changes to be applied.

How do I create a new migration in Django?

You can create a new migration by running the command python manage.py makemigrations. This will generate a new migration file based on the changes you've made to your models.

What happens if I want to roll back a migration?

To roll back a migration, you can use the command python manage.py migrate <app_name> <migration_name>. This will revert your database to the state defined by the specified migration.
