How to implement a simple notification system in Rails? : <p>I would like to implement a simple notification system in Rails(no gem). Let's say I have a blog app using Devise for auth, and on a post posted by user A(logined) there is a "Like" button, if another user, user B clicks on that button, I would like to notify user A with a simple notification like: "User B liked your post!".</p>

<p>I'm new to Rails.</p>
