Overview

Base class for SMS responders. To define a responder start by generating a sublcass.

rails generate twilio:rails:sms_responder ThankYou

This will create a new class in app/sms_responders/thank_you_responder.rb which will subclass this class. It must be registered with the framework in the initializer for it to be available. The generator does this.

# config/initializers/twilio_rails.rb
config.sms_responders.register { ThankYouResponder }

Then the responder must implement the #handle? and #reply methods. If the #handle? method returns true then the #reply method will be called to generate the body of the response, and send that message back as an SMS. Only one responder will be called for a given message.

Examples:

class ThankYouResponder < ::Twilio::Rails::SMS::DelegatedResponder
  def handle?
    matches?(/thank you/)
  end

  def reply
    "Thank you too!"
  end
end
