Rails API pagination with kaminari using http headers

rails_api_pagination.md

def respond_with_paginated(collection)
  %w( current_page
      total_pages
      total_count
      prev_page
      next_page
      first_page?
      last_page?
  ).each do |method_name|
    field_name  = "X-Kaminari-#{method_name.titleize.gsub(/\s/, '-')}"
    field_value = collection.send(:"#{method_name}").to_s
    response.headers[field_name] = field_value
  end
  response.headers['X-Kaminari'] = "true"
  respond_with(collection)
end

Herm, I just learned about the Link HTTP header. RFC-5988 is probably a better solution.
