Beschreibung

I'm trying to figure out a way to always run code after a migration happens, in my case I'm using mysql and I'd like to ensure a set of views is up to date so that we don't have to manually re-create our views after the underlying schema of the table changes. I noticed there is an endMigration event in the driver, maybe there is a way to hook into this?

Or perhaps if I put an index.js file in the migrations directory I can monkey patch the up function to call my recreate views methods after migrations are done?

Thanks for your help.

Research-Richtung
Investigate the existing event system in db migrate, specifically the 'endMigration' event in the driver. Look at how other hooks are implemented and propose adding an 'afterMigrate' event that fires after each migration. Consider the API design and backward compatibility. The issue lacks concrete implementation details, so explore the codebase in the repo (e.g., lib/driver.js) and open a discussion on the relevant files.
