Question for @apotonick

class ThingRepresentation < Representable::Decorator
  include Representable::JSON

  property :field
end

# This works great.
ThingRepresentation.new(Thing.new).to_json # => { "field": "thing value" }

# This does not work.
ThingRepresentation.new([Thing.new, Thing.new]).to_json # => [{ "field": "thing1 value" }, { "field": "thing2 value" }]

# How can I achieve this?
# This seems to be close to what I want: https://github.com/apotonick/representable/pull/22

In representable-1.5.1 this will work.

class ThingsRepresenter < Representable::Decorator
  include Representable::JSON::Collection

  items decorator: ThingRepresentation
end

ThingsRepresentation.new([Thing.new, Thing.new]).to_json
