Reststop

Reststop makes it easy to write RESTful applications in Camping.

For an example of a complete Reststop-based Camping app, have a look at github.com/camping/reststop/blob/master/examples/blog.rb

Reststop essentially gives you three things:

1. Camping controllers that respond to the standard REST verbs:

  • create (POST)

  • read (GET)

  • update (PUT)

  • destroy (DELETE)

  • list (GET)

Custom actions are also possible. See the Reststop::Controllers#REST method documentation for usage info.

2. Camping views grouped by output format:

Your views module:

module Foobar::Views
  module HTML
    def foo
      html do
        p "Hello World"
      end
    end
  end
  module XML
    def foo
      tag!('foo')
        "Hello World"
      end
    end
  end
end

Your render call:

render(:foo, :XML)

See the Camping#render method documentation for usage info.

3. Nice URLs to bring it all together:

For example a list of kittens in the default format (HTML) is available at:

/kittens

The list, in RSS format:

/kittens.rss

Kitten with id 1, in XML format:

/kittens/1.xml

Using custom action 'meow' on kitten with id 1:

/kittens/1/meow

In other words, say you have a “kittens” resource; you can make a GET request to yourapp.com/kittens.xml and get a list of kittens through your Kittens controller's list, formatted using your XML view module.

Looking for Restr, the very simple REST client?

Due to its popularity, Restr, the “very simple rest client”, has been moved out to its own gem. Restr now lives under rubyforge.org/projects/restr/ and can be installed using:

gem install restr

Restr is basically a wrapper around Ruby's Net::HTTP, offering a more RESTfully meaningful interface.

See the “Restr documentation” for more info, but here's a simple example of RESTful interaction with Restr:

require 'restr'
kitten = Restr.get('http://example.com/kittens/1.xml')
puts kitten['name']
puts kitten['colour']

kitten['colour'] = 'black'
kitten = Restr.put('http://example.com/kittens/1.xml', kitten)
