Rails: run rake tasks like migrations

问题:

My dev team needs to more precisely run rake tasks. There are certain tasks that need to be only run once after a specific code change. Without getting too specific, it would be like needing to update certain existing users records after a new business rule for new users is implemented in the code.

We like how migrations use a db table for logging. Is there a similar tool for rake tasks? Can we hack Rails'/ActiveRecord's migrations system for rake tasks?

We'd prefer not to mix db-related migrations with rake tasks, so any solution that explicitly keeps these separate would be great.

Thanks.

These are migrations. Use migrations. Unless there's some additional constraints you didn't mention, using anything but migrations would be a hack.

I created a gem for exactly what you need: http://eyaleizenberg.blogspot.co.il/2014/08/how-to-keep-track-of-rails-rake-tasks.html
