Setting validations on multiple attributes: A noobies attempt
Hi there, I was trying to be a little creative and play around with ruby. In my RoR model file I wrote this: Hash[''title'', ''teaser''].each do |k ,v| validates v.to_sym :presence => true end It''s fairly obvious what I''m trying to achieve here, but the validation is only set for the last element, ''teaser''. I know there is something about ruby block only returning the last line (or something), but is there a way to circumvent that?

Inside the block, k is assigned ''title'' and v is assigned ''teaser''. try [''title'', ''teaser''].each do |k| validates k.to_sym, :presence => true end> It''s fairly obvious what I''m trying to achieve here, but the validation > is only set for the last element, ''teaser''.
