Method from the future! (Hash#transform_keys)

In rails 4 the transform_keys method will be at your disposal. It works in the same way as stringify_keys or symbolize_keys, but takes a block as an argument. It allows you to specify how you would like to format your keys.

hash = {foo: 'one', bar: 'two', baz: 'three'}
hash.transform_keys do |key|
    key.to_s.capitalize
end
 => {"Foo"=>"one", "Bar"=>"two", "Baz"=>"three"}
