how do implement a rails popularity/trending algorithm!!

• I'm making a web app and I want to sort through a model based on popularity/trendiness, kind of like reddit/hacker news. 192.168.0.1 I want to determine the popularity based on the count of comments, likes, and impression divided by the creation date from the whatsapp web

Here's a gist that contains Reddit's popularity algorithm that you could use. It's pretty simple and just uses upvote, but you could add in comments and impressions to the calculation too. https://gist.github.com/nanosplit/db42e507c5d1d984b664868db10a3669
