Ruby/Rails using || to determine value, using an empty string instead of a nil value

Question

I usually do

 value = input || \"default\"

so if input = nil

 value = \"default\"

But how can I do this so in

Answer 1

Maybe irrelavant but I would use highline like this:

require "highline/import"

input = ask('Input: ') { |q| q.default = "default" }

It works without Rails. Really neat solution.
