validates\_presence\_of :region, :if =\> [“CA”, “US”].include?(:country)  
validates\_presence\_of :region, :if =\> Proc.new { |a| [“CA”,  
“US”].include?(a.country) }

The top one works, but the bottom does not. Obviously the top is  
easier to read, but I am just curious to why the bottom one returns  
false.

Thanks
