reCaptcha

ReCaptcha

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.

        

1. class User::RegistrationsController < Devise::RegistrationsController
2. #
3. # Other Codes
4. def create
5. ## To build the resource
6. build_resource(sign_up_params)
7. ## Verifying Captcha
8. if verify_recaptcha(model: resource)
9. super
10. else
11. render 'new'
12. end
13. end
14. #
15. # Other Codes
16. 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

    

    https://www.google.com/recaptcha/admin/create#list

    1-  Label - recaptcha Test

    2-  reCAPTCHA type - reCAPTCHA v2  and after select 1 option 

          ("I'm not a robot" tickbox)

    3-  Domains -  localhost, for heroku- heroku.com

   

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

     

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

OR

                     add .env file in project source add key

 export RECAPTCHA_SITE_KEY = '6LcLFdIUAAAAAFKQUU4b3HnWYtssgTWdsnQZsVXU'

 export RECAPTCHA_SECRET_KEY = '6LcLFdIUAAAAAA4Z66WTWojY0_RsyR7DqnhtOYUf'

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"}
