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?
