HalApi::Rails

Welcome to hal_api-rails. This is a binding between the responders / roar / roar-rails gems and the the PRX HAL api.

Installation

Add this line to your application's Gemfile:

gem 'hal_api-rails'

Then add a gem for paging through ActiveRecord result sets:

gem 'kaminari'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hal_api-rails

Usage

This gem provides a number of additions to the roar gem HAL support.

There are several parts of it that need to be used in your apps:

1) Add to your API controllers:

require 'hal_api/rails'

class Api::BaseController < ApplicationController
  include HalApi::Controller
  ...
end

2) Add to your ActiveRecord models used in your API (perhaps in a base model class):

class BaseModel < ActiveRecord::Base
  self.abstract_class = true

  include RepresentedModel
end

3) Use the base representer, define your own CURIEs:

class Api::BaseRepresenter < HalApi::Representer
  curies(:prx) do
    [{
      name: :foo,
      href: "http://foo.bar/relation/{rel}",
      templated: true
    }]
  end

  def index_url_params
    '{?page,per,zoom}'
  end

  def show_url_params
    '{?zoom}'
  end
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
