How to use custom helper method's return value

Question

I have a method in application_helper:

def methodname(argument)
 if "XXXX".match(/#{argument}/i).present?
 puts "YYYY"
else
end

And in console:

require "#{Rails.root}/app/helpers/application_helper"
=> true
include ApplicationHelper
=> Object
> methodname("argument")
YYYY=> nil
> loremipsum = methodname("argument")
YYYY=> nil
> loremipsum
=> nil

So it returns YYYY which is correct but it also returns nil for some reason beyond my understanding. I only need YYYY. How can I "extract" / use it? I would like:

> somemagicalcommand
> "YYYY"

:)

TIA!

You are using the puts function, which outputs something on the console, like a printf on C, or System.out.printf in Java.

If instead of using puts you return the value, I think you may have the result you're looking for :).

def methodname(argument) return "YYYY" if "XXXX".match(/#{argument}/i).present? end
