Integrating a Voting System into Your Blog App

This article is about adding a voting system to your blog app. We all want to allow users to show their interest and react to an article through voting and also get the article with the highest vote. The voting table will set the relationship between the vote by each user and the voted article. We will also set a uniqueness of a vote per user, this will make sure an article is voted once by a user. To create our vote controller we need to create our Votes controller by adding the following code to our app/controllers/vote.rb.
