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?

Regards,

Nadeem

RoR model file I wrote this:

Hash[‘title’, ‘teaser’].each do |k ,v|

validates v.to_sym :presence => true

end

Hash[‘title’, ‘teaser’] creates a hash with one pair. 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
