Question

I am using Sinatra and have organized my application into models, views and routes (as suggested here).

I have come across several guides (such as Sinatra Book) on using before filters with routes. Is there any way to use before filters for models?

I am using the Sinatra ActiveRecord extension if it helps.

Answer 1

ActiveRecord has such before filters out-of-the-box.
It supports before_save, after_save, before_create, after_create, and even before_validation and after_validation.
