Rails - Sep 2006 - check if an array/hash contains a particular element

Hi,

Is there any convenient method to check if an array contains a 
particular element?  eg.

abc = {''ele1'',''ele2''}

if abc contains ''ele1''
       =======blablablab...
end

Thanks.

That''s a hash, not an array.  I think you mean:

   ["ele1", "ele2"]
> if abc contains ''ele1''
if abc.include?(''ele1'')
