How do I handle relationship migrations in SQLAlchemy?
To handle relationship migrations in SQLAlchemy, you can use Alembic for managing database schema changes.
Can you give me an example of how to set up Alembic for this?
Sure! First, install Alembic using pip. Then, initialize it with alembic init alembic
. Configure your alembic.ini
file to connect to your database.
What if I need to change a relationship type?
You can create a new migration script using alembic revision --autogenerate -m 'change relationship type'
and modify the relationship in your models.
How do I apply the migration after making changes?
Run alembic upgrade head
to apply the latest migration to your database.
