So I finally had time exploring Rails 5 after quite a busy schedule. First order of business– check out Action Cable as it seems to be one of the most promising features to Rails 5.

Aktibibo is a simple Ruby gem that makes your model activatable. It allows an ActiveRecord model to be declared as “activatable” thus providing scopes for querying and filtering objects. Of course, the module adds convenience methods for setting an instance as active, inactive or deactivated. As an additional feature, it also saves the activation and deactivation dates because it uses datetime DB…

by Kat Padilla • • 0 Comments
In the Ruby world, mixins are very popular. In fact, I’ve created a number of basic mixins (or concerns) in Rails projects and so it came to a point where I wanted to try converting it to a gem. Why? Because why not? Well, just for the experience. Anyway, my first RubyGem is called Sorty Sorter. It sorts AR collection…

How To Time Travel Using ActiveSupport TimeHelpers
by Kat Padilla • • 2 Comments
So I needed to test “time”…quite literally. I needed to test some time-related validity logic in Rails. I read that in Rails 4.1, ActiveSupport::Testing::TimeHelpers was added to make it easier for everyone to withstand the test of time. Err, I mean to test time. No disrespect to TimeCop, I know it has its own advantages, but the built-in…
