How do I create migrations using SQLAlchemy?

To create migrations in SQLAlchemy, you typically use Alembic, which is a lightweight database migration tool for use with SQLAlchemy.

Can you show me the steps to set it up?

Sure! First, install Alembic using pip. Then, initialize it in your project with alembic init alembic. This creates a directory for your migrations.

What command do I use to generate a new migration?

You can generate a new migration by running alembic revision --autogenerate -m "your_message_here". This will create a new migration file.

How do I apply the migration to the database?

To apply the migration, use the command alembic upgrade head. This will apply all pending migrations to your database.
