Rails Devise: after_confirmation

Question

Is there a way to create a after_confirmation :do_something ?

The goal is to send an e-mail after the user confirms using Devise :confirmable

Answer 1

We're combining answers from @Bernát and @RyanJM:

def confirm!
  super
  if confirmed_at_changed? and confirmed_at_was.nil?
    do_stuff
  end
end

This seems a bit more performance aware and safe than the two answers separately.
