Rails - Nov 2006 - Unexpected behaviour looping an array in a model.

Hi, I''m attempting to loop through an array in a method in a model,
Product.rb, and return a value if a certain conditional is met. I''m
having some trouble however, as it doesn''t seem to be working as
expected.

The method from my model is as follows:

  def product_availability_label
    QCC.config(:product_availability).each do |av|
     "#{av.first}" if av.last == self.availability
    end
  end

The product availability array is declared elsewhere as:

config :product_availability, [[''Immediate'',1],[''1
Week'',2],[''2
Weeks'',3],[''3 Weeks'',4],[''1
Month'',5]]

Returning a .type on QCC.config(:product_availability) from within
Product.rb confirms it''s an array and is the array I''m
expecting,
however the output from the product_availability_label method is
"Immediate11 Week22 Weeks33 Weeks41 Month5", rather than the expected
"Immediate" (in the instance where self.availability is 1). No errors
are raised.

I know I could do this from within a helper, but before I make any
alterations, I''d rather understand what''s going on.
I''m using Ruby
1.8.5, Rails 1.1.6 on OSX should it make any difference.

Thanks :)

This is normal: The each method returns the array it was called on
Just add a return statement.

Oh dear. Lack of caffeine I think. Thanks Fred!
