I am looking for an open source web analytic for my Rails 4.2 app, so after some research I found that piwik fit my needs. can I use "piwik" with postgresql ? it seems that they only support mysql but I am not sure if it still true at this moment!
also I've found a post about how to integrate it within Rails here but they use piwik_analytics which is a Gem for Ruby on Rails 3.x and may not work with 4.2 !
All the information I've found are a little outdated and I am not sure if there is a way to make it work with my current requirements. any help please ?
