    Hi friends,
    Few days back I was facing difficulty in integrating recaptcha with rails so once after integrated it and I though it would be helpful for you guyz, if I mention it step-by-step as I did.

    1. Open your Gemfile and add this code:
     

    gem "recaptcha", require: "recaptcha/rails"

     

    2. Now run bundle

    bundle install

     

    3. Then I inherited devise registration controller and overridden the create method of it.

    class User::RegistrationsController < Devise::RegistrationsController
      #
      # Other Codes
    
       def create
        ## To build the resource
        build_resource(sign_up_params)   
        ## Verifying Captcha
        if verify_recaptcha(model: resource) 
          super
        else
          render 'new'
        end
      end
    
      #
      # Other Codes
    end

     

    4. Now you need to get the public and secret key by registering into Google recaptcha account.

    The link is https://www.google.com/recaptcha/admin

     

    5. Now add the configurations for recaptcha at /config/initializer/recaptcha.rb

    Recaptcha.configure do |config|
       config.public_key  = 'Replace with your public key'
       config.private_key = 'Replace with private key'
    end

     

    6. Add the recaptcha tags to app/views/devise/registrations/new

    <div><%= recaptcha_tags %></div>

     

    7. Now we need to tell the route to go to our registration controller instead of devise registration controller. So routes needs to be modified to:

    devise_for :users, :controllers => {:registrations => "user/registrations"}


    Thus you are now ready to use recaptcha with devise in your rails application.
