How do I use Alembic for data migrations in my database?
Alembic is a lightweight database migration tool for use with SQLAlchemy. To get started, you need to install it using pip.
What are the basic commands I need to know?
The basic commands include alembic init to create a new migration environment, alembic revision to create a new migration script, and alembic upgrade to apply migrations.
How do I create a new migration script?
You can create a new migration script by running alembic revision -m "your_message_here". This will generate a new script in the versions directory.
Can I roll back a migration?
Yes, you can roll back a migration using the command alembic downgrade <revision>, where <revision> is the identifier of the migration you want to revert.
