How to use private_pub gem on heroku in ruby on rails

In this post I am going to show how to use private_pub gem on heroku. Before going to use it we have to setup private_pub server on heroku. Use this link to setup the server.

Private Pub gem is a very nice solution for pushing real time data and it’s open-source . Now create a rails app using “rails new demo_private_pub”. Then we have to add the gems given below

gem ‘private_pub’
gem ‘thin’

After adding the gem bundle it. Then use this “rails g private_pub:install” to create private_pub settings files. It will create two file “config/private_pub.yml” and “private_pub.ru”. We have to change the content of private_pub.yml to below one

production:
secret_token: “batkaro”
signature_expiration: 86400 # one day

We got “server: http://fayeserver.herokuapp.com/faye ” from private_pub server setup. Because private pub is running on this server.

Then we have to move file “private_pub.ru” inside “config / initializers” of application.
After that remove the “run PrivatePub.faye_app” from “private_pub.ru”.

Now we are ready use to private_pub.

Add this “//= require private_pub” to applications.js file.

<%= subscribe_to "/messages/new" %>  # use this for subscribing to a channel

<% publish_to "/messages/new" do %> # use this for publishing the data to a channel.
  $("#post-list-div").append("<%= j render(@post) %>");
<% end %>
