Not compatible with active_model_serializers 0.9.x

[icem]

According to active_model_serializers changelog they removed method Model#active_model_serializer. The problem that rocket_pants uses this method if it's present to get serializer from model:

serializer = object.active_model_serializer if object.respond_to?(:active_model_serializer) && serializer.nil?

The workaround to specify serializer explicitly on expose call.

Interesting - I'll take a look into how they handle the detection now and see how hard it would be to integrate into RP

For people on rails 4.2 looking for easy workaround while issue not fixed:
I added this to initializers folder:

# Extracted from old active_model_serializers 0.8
# This patch fixes rocket_pants 1.11.0 compatibility with active_model_serializers 0.9
module ActiveModel::SerializerSupport
  extend ActiveSupport::Concern

  module ClassMethods #:nodoc:
    if "".respond_to?(:safe_constantize)
      def active_model_serializer
        "#{self.name}Serializer".safe_constantize
      end
    else
      def active_model_serializer
        begin
          "#{self.name}Serializer".constantize
        rescue NameError => e
          raise unless e.message =~ /uninitialized constant/
        end
      end
    end
  end

  # Returns a model serializer for this object considering its namespace.
  def active_model_serializer
    self.class.active_model_serializer
  end

  alias :read_attribute_for_serialization :send
end

module ActiveModel::ArraySerializerSupport
  def active_model_serializer
    ActiveModel::ArraySerializer
  end
end

Array.send(:include, ActiveModel::ArraySerializerSupport)
Set.send(:include, ActiveModel::ArraySerializerSupport)

{
    :active_record => 'ActiveRecord::Relation',
    :mongoid => 'Mongoid::Criteria'
}.each do |orm, rel_class|
  ActiveSupport.on_load(orm) do
    include ActiveModel::SerializerSupport
    rel_class.constantize.send(:include, ActiveModel::ArraySerializerSupport)
  end
end

Be sure to remove this code when issue will be fixed.

There is a potential integration point for this in ActiveModel::Serializer.serializer_for, but I want to test compatibility etc before implementing it first.

[Sutto]

For a start, given there is a work around for this - that is to say, you can manually set :serializer or define your own active_model_serializer method, I'm going to leave this out of 1.12 to avoid accidentally breaking stuff.

I'll retag this to 1.13, and take a look for that in the near future.

Again - patches / specs welcome :)

Just a note, but I'm experimenting with bringing RP up to spec with AMS 0.10.x which has even further interface changes above and beyond 0.9.x

I'll let you know how I get on.
