Question

I have the following code in my controller:

@video=Video.find(params[:id])
        @video.increment!(:votes)
        respond_to do|format|
        format.js  

This works fine.I want to add recaptcha validation to it.Iam using Ambethia recaptcha.

Answer 1

• Add gem ‘recaptcha’, :require => ‘recaptcha/rails’ to your Gemfile, run bundle
• Create your reCAPTCHA keys: https://www.google.com/recaptcha/admin/create
• Add the public and private key to your project and restart your server:

config/initializers/recaptcha.rb

Recaptcha.configure do |config|
  config.public_key  = 'xxx'
  config.private_key = 'yyy'
end

in your view:

<%= recaptcha_tags %>

in your controller:

 def create
   if verify_recaptcha

   else

   end
 end
