Override Devise Controllers

c. Devise 2.1.2
ref: https://github.com/plataformatec/devise/issues/1561


E.g. you may want to send back json instead of html on login, etc.

Steps:
1. Override the controller (put in the controllers dir)

class SessionsController < Devise::SessionsController

2. Specify route in your route.rb file

YourApp::Application.routes.draw do
  ...
  devise_for :users, :controllers =>
      {:sessions => 'sessions',
       :registrations=>"registrations",
       :passwords=>"passwords"}


Example overridden controller

class PasswordsController < Devise::PasswordsController

  def create
    #same as in parent
    self.resource = resource_class.send_reset_password_instructions(resource_params)
    
    #send json instead of html 
    if successfully_sent?(resource)
      render :json=>{:success=>true}
    else
      render :json=>{:success=>false}
    end
  end


end
