Rails: Devise: Sending an email after user comfirms registration

问题

My application is using Devise, and is sending out confirmation emails properly, and confirming users properly as well after they click on the confirmation link. I would also like to send a second email AFTER the user is confirmed.

There is a lot of advice on how to delay confirmation, or 2-step confirmation, but nothing on what I'm looking for (that I can find).

The Devise::Module::Confirmable documentation tells me that the method to use is confirm!, but I am not sure how to do this. Any ideas?

回答1:

Rails Devise: after_confirmation

Simply define an after_save callback that checks to see if a user was confirmed, and if so, sends the email.

If you want to save a few CPU cycles, you could override the Devise ConfirmationsController with something like this:

class ConfirmationsController < Devise::ConfirmationsController

    def show
        self.resource = resource_class.confirm_by_token(params[:confirmation_token])

        if resource.errors.empty?
            set_flash_message(:notice, :confirmed) if is_navigational_format?
            sign_in(resource_name, resource)

            # Send the user a second email          
            send_post_confirmation_email

            respond_with_navigational(resource){ redirect_to after_confirmation_path_for(resource_name, resource) }
        else
            respond_with_navigational(resource.errors, :status => :unprocessable_entity){ render :new }
        end
    end
end
