They add (at least in Ruby) a few lines of code to a program; and take things like Email out of the User model and put them in a more appropriate place.

- malyk 14y agoAnd you'd never know that they existed if you look at the user model... My stance is that things like sending email should be explicit calls so they are obvious. Sending email when registering a new user, for example, should be in the if user.save branch in your controllers or, if you have a more SOAish app, in the service that creates users. def create user = User.create(params[:user]) if user.save Emailer.new_user_email.deliver render 'welcome' else render 'oh shit' end end Or, refactor that out a bit (ONLY IF NECESSARY!) def create user = UserService.create_user_from(params[:user]) if user render 'welcome' else render 'oh shit' end end
