I think the easiest thing to do is to have each attribute represented as
a column in your scheme. So instead of having one column,
"ideal_body_type" have one for skinny, fat, super man, each holding a
boolean value.

On validation, you can make sure atleast one of them is checked:

before_save :confirm_body_type

def body_type
 flag - 0
 [:skinny, :fat, :super_man].each |body_type|
   flag += 1 unless send(body_type).nil?
 end
 return false if flag.zero? else true
end

ok, so the example is cracked but the idea is somewhere in there...
