as_json for arrays?

Hi.

The file /rails/activesupport/lib/active_support/json/encoders/enumerable.rb

Has:

class Array   (...)   def as_json(options = nil) #:nodoc:     self   end end

I want a as_json method FooModel.all.as_json(:only => [...]) that will work same as FooModel.first.as_json(:only => [...]).

I had to write my own method in a initializer: class Array   def as_json_preserve_only_keys(preserve_keys)     self.collect do |el|       el.as_json(:only => preserve_keys)     end   end end

Is there a better way to do this? Why does the Array method now look at the "options" parameter?
