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

I'm using Devise 3.1.2, it has a placeholder method after_confirmation which is called after the confirmation finished successfully. We just need to override this method in User model.

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable, :confirmable

  # Override Devise::Confirmable#after_confirmation
  def after_confirmation
    # Do something...
  end
end

See: Devise 3.5.9 Source Code: https://github.com/plataformatec/devise/blob/d293e00ef5f431129108c1cbebe942b32e6ba616/lib/devise/models/confirmable.rb

(Original answer)

but you should be able to put a before_save callback on the user (extra credit for using an observer) and check if confirmed_at was just set by devise. You can do something like:

  send_the_email if self.confirmed_at_changed?
