Ruby: Easiest Way to Filter Hash Keys?

Question

I have a hash that looks something like this:

params = { :irrelevant => \"A String\",
           :choice1 => \"Oh look, another one\",
           :choi         


        

Answer 1

The easiest way is to include the gem 'activesupport' (or gem 'active_support').

params.slice(:choice1, :choice2, :choice3)
