Active Model Serializer Pagination Link Not Generated

Question

I'm using the master Active Model Serializer and the Pagination Serializer. This is may Pagination Serializer

# pagination collection serializer
class PaginationSerializer < ActiveModel::Serializer::CollectionSerializer

  def initialize(object, options = {})
    meta_key = options[:meta_key] || :meta
    options[meta_key] ||= {}
    options[meta_key][:pagination] = {
      current_page: object.current_page,
      next_page: object.next_page,
      prev_page: object.prev_page,
      total_pages: object.total_pages,
      total_count: object.total_count,
      size: object.total_count
    }
    super(object, options)
  end

end

This is my rendering code.

render json: formulas, serializer: PaginationSerializer, each_serializer: FormulaSimpleSerializer

There no meta key on the result. This happens after upgrading from 0.10.0.RC3 to master. Any idea?

# my_app/app/application_controller.rb
...
def pagination_dict(object)
{
  current_page: object.current_page,
  next_page: object.next_page,
  prev_page: object.prev_page,
  total_pages: object.total_pages,
  total_count: object.total_count
}
end

# my_app/config/initializers/active_model_serializer.rb
ActiveModel::Serializer.config.adapter = :json

Render code:

render json: formulas, meta: pagination_dict(formulas)
