Ruby/Rails passing array to case

Question

Here is the scenario:

case code
  when 'www', '', nil
    false
  when 'code1', 'code2'... 'code_n' # The array STORE_CODES contains all the codes 
    true
  else
    false
end

How can I use STORE_CODES directly after when instead of 'code1', 'code2'... 'code_n'

I've searched throughly before posting this, could you please explain how is it duplicate of the post mentioned — Hable, Aug 15 '13 at 08:36

just use:

when *STORE_CODES

instead of :

when 'code1', 'code2'... 'code_n'

For those curious, `*` is a splat operator which (among other things) turns arrays into comma separated strings. Good info on this here: https://endofline.wordpress.com/2011/01/21/the-strange-ruby-splat/ – Adam Grant Jan 18 '16 at 22:41
