Add a customer renderer but I get missing template

Hi,

I’m trying to include the support of Msgpack in Rails 3.2 but when I try to return a mpac response, I get an error concerning a missing template.

My renderer:

  Mime::Type.register 'application/x-mpac', :mpac
ActionController::Renderers.add :mpac do |mpac, options|
self.content_type ||= Mime::MPAC
self.response_body = mpac.respond_to?(:to_msgpack) ? mpac.to_msgpack : mpac
end

My controller:

  class UsersController < ApplicationController
respond_to :mpac, :json
def show
respond_with({ hello: 'world' })
end
end

And my serializer:


require 'msgpack'
module ActiveModel
module Serializers
module MPAC
extend ActiveSupport::Concern
include ActiveModel::Serialization
included do
extend ActiveModel::Naming
end
def to_mpac(options = nil)
serializable_hash(options).to_msgpack
end
alias_method :to_msgpack, :to_mpac
def from_mpac(msg)
MessagePack.unpack(msg)
end
end
end
end

Anyone has an idea ?

Thanks.
