restpack-resource

RESTful resource paging, side-loading, filtering and sorting.

Define your models:

class Channel
  include DataMapper::Resource
  include RestPack::Resource
  property :id, Serial
  property :name, String, :length => 512
  timestamps :at
  
  validates_presence_of :name
  
  has n, :applications
  has n, :domains
  has n, :configurations
  
  resource_can_include :applications, :domains, :configurations
  resource_can_filter_by :id
  resource_can_sort_by :id, :created_at, :modified_at
  
  def as_resource
    {
      :id => id,
      :name => name,
      :url => "/api/v1/channels/#{id}.json"
    }
  end
end

Then you can do this in your API (Grape in this example):

module ChannelAPI
  class V1 < Grape::API
    version 'v1', :using => :path, :format => :json

    resource :channels do
      get do        
        Channel.paged_resource(params)
      end
    end
  end
end

Which gives you endpoints such as:

/api/v1/channels.json?includes=applications,domains,configurations
