Thats pretty nice, as you say the struct is pretty similar to the hash
so multiple keys can be checked for duplicates.  This is how i have it
working now but i may change to your solution above.  My solution doesnt
feel the most effecient.

for obj in company_b.send(dyn_method)
  if !company_a.send(dyn_method).detect { |t| t.id == obj.id}
   company_a.send(dyn_method) << obj
  end
end
