Mikyung’s, a REST agent framework built on top of Restfulie can be seen at http://github.com/caelum/mikyung.
CRUD through HTTP is a good step forward to using resources and becoming RESTful, another step further into it is to make use of hypermedia and semantic meaningful media types: this gem allows you to do it really fast.
You can read the article on using the web for real which gives an introduction to hypermedia/resources/services.
- Easy —> writing hypermedia and semantic meaningful media type aware clients
- Small → it’s not a bloated solution with a huge list of APIs
- HATEOAS —> clients you are unaware of will not bother if you change
- HATEOAS —> consumed resources will not affect your software whenever they change their flow
- Adaptability —> clients are able to adapt to your changes
Appart from the simple server and client examples provided here, you can find the following links useful:
In the server side, all you need to do is notify inherited_resources which media types you are able to represent your resource:
class OrdersController < ApplicationController include Restfulie::Server::ActionController::Base respond_to :atom, :html, :xml, :commerce, :opensearch def index respond_with @orders = Order.all end def show respond_with @order = Order.find(params[:id]) end end
That’s it. Restfulie will take care of rendering a valid representation according to content negotiation. You can configure the rendering process through a custom tokamak view:
describe_collection(@orders) do |collection| collection.id = orders_url collection.links << link( :rel => :create, :href => orders_url ) collection.describe_members end
You can go through an entire application by watching this video or downloading an example application.
The following example is a partial REST client implementation that navigates through some relations:
order = Restfulie.at('http://localhost:3000/orders/1').get! order.items.each { |item| puts items } receipt = order.payment.post! { :amount => 500 } puts receipt.id
In order to create a full REST client, watch this video.
You can view an entire application running Restfulie under spec/integration/order/server and spec/integration/order/client in this git repository.
You can also download a full example of a REST based agent and server using Restfulie and Mikyung, according to the Rest Architecture Maturity Model.
For client side usage, execute:
gem install activesupport gem install restfulie
For server side usage, execute:
gem install restfulie
If you want to build the project and run its tests, remember to install all (client and server) required gem.
Bundler is required to easily manage dependencies
bundle install
