This is very good to understand Alembic. Btw note to all, video is for understanding how it works, in real world we shouldn't manually edit content in version files (it should be auto generated it for you.) What you want to edit is model files that has table schema detail.

Why people use flask migrate and not alembic directly with --autogenerate?

Sergio, very nice on best practices! Congrats!
How about integration with environment variables with .env and ci/cd pipeline (staging / production) for the next episode?

I thought this video was well presented and paced. One small thing — you have a pretty intense gaze; I’d probably do something to lessen the impact of that on your videos.
