Order_by Rails Serializer transformation - ruby-on-rails

Question

My understanding is that you can only call the AMS when you're using render like this:
render json: foos, each_serializer: FoosSerializer
But what if I wanted to do something with the result from the serialized resource after it's been serialized? Is that possible? My issue is that my serializer calls a method on the resource to transform one of the resource's attributes and I need to order by that attribute before passing it to the front end.
When I do the below:
ActiveModel::SerializableResource.new(
foos,
each_serializer: FoosSerializer
).to_json
I get back json, but can I transform it back to something that I can call order_by on?
EDIT:
I have this:
JSON.parse(ActiveModel::SerializableResource.new(
foos,
each_serializer: FoosSerializer
).to_json).sort {|x,y| x[:name] <=> y[:name]}
But this seems silly to call to_json and parse in order to call order between as I still need to do something with the parsed result after ward.

Answer 1

How about creating another transformer serializer as FooSortSerializer
class FooSortSerializer < ActiveModel::Serializer
def attributes(_options = {}, _reload = false)
object.collect do |foo_instance|
FooSerializer.new(foo_instance).attributes
end.sort {|x,y| x[:name] <=> y[:name]
end
end
In controller
render json: foos, serializer: FooSortSerializer
