Rails Devise: after_confirmation

问题

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.

(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?

http://api.rubyonrails.org/classes/ActiveModel/Dirty.html for more details on checking the change on the field.

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

回答3:

You can override the confirm! method:

def confirm!
  super
  do_something
end

Discussion about the topic is at https://github.com/plataformatec/devise/issues/812. They say that there are no callbacks like after_confirmation :do_something because that approach would require a lot of different callbacks.

Rails 4:

combining multiple answers above

  def first_confirmation?
    previous_changes[:confirmed_at] && previous_changes[:confirmed_at].first.nil?
  end

  def confirm!
    super
    if first_confirmation?
      # do first confirmation stuff
    end
  end

according to the Devise 3.5.9 source code, you can simply define a method on the Devise Resource model, e.g.:

  class User < ActiveRecord::Base
  ...
    def after_confirmation
       do_something
    end
  end

回答6:

I don't see that callback too, maybe you can try to override the confirmation method and call your callback there.

def send_confirmation_instructions(attributes={})
  super(attributes)
  your_method_here
end

回答7:

You can override the confirm! method on your model

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

  def confirm!
    super
    do_something
  end
end

There is a discussion about the topic is https://github.com/plataformatec/devise/issues/812. I tried this way, and it worked great.

回答8:

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.
