Ruby Missing Components - DB Tables

When you generate the new table, why doesn't the migration happen automatically?

Why does ruby not do the migrate automatically? Just curious.

Not sure why it doesn't run automatically in dev. I know in production, special care is needed surrounding migrations (see https://www.tintup.com/blog/automatic-rails-migrations-in-production-yes-or-no/), and the Rails team may have just applied that same logic to dev.

Thanks for the answer, Jay! It gives one something to think about, especially in the future when working on schema in large databases. Does Treehouse use MySQL?

We do, but personally, if I were starting over from scratch I'd have used PostgreSQL. Regardless, both options should be evaluated carefully for the project at hand.
