SwaggerYard::Rails

The SwaggerYard::Rails gem is a Rails Engine designed to parse your Yardocs API controllers using SwaggerYard. It'll create a Swagger-UI complaint JSON to be served out through where you mount SwaggerYard::Rails::Engine.

Installation

Add this line to your application's Gemfile:

gem 'swagger_yard-rails'

And then execute:

$ bundle

Usage

Mount your engine

# add to config/routes.rb
mount SwaggerYard::Rails::Engine, at: "/swagger"

Add JS/CSS for UI

In your Gemfile (until the release of 2.1.3):

gem 'swagger-ui_rails2', github: '3scale/swagger-ui_rails', branch: 'dev-2.1.3'

https://github.com/3scale/swagger-ui_rails/tree/dev-2.1.3#usage

in application.css:

*= require swagger-ui2/index

in application.js:

//= require swagger-ui2/index

Note: swagger_yard-rails will handle the template

Configure SwaggerYard

See Getting Started in the swagger_yard docs for details.

# config/initializers/swagger_yard.rb
SwaggerYard.configure do |config|
  # your configuration here
end

Write YARD documentation

Write YARD documentation for your controllers and models as described in SwaggerYard Usage.

To include a controller in your swagger definition, add a @resource tag to the controller's class documentation.

# @resource Pet
class PetsController < ApplicationController
  # ...
end

Once a controller has been tagged as a swagger resource, all public instance methods with docstrings will be candidates for inclusion as swagger apis, even if they don't include @path tags. swagger_yard-rails includes a path discovery function implementation that uses the Rails router to lookup paths, allowing @path tags to be omitted.

swagger_yard-rails also provides a @route tag to indicate a named route to be connected to an api action.

# config/routes.rb
Dummy::Application.routes.draw do
  get '/greet', to: 'hello#greeting', as: 'greeting'
end

# @resource Hello
class HelloController < ApplicationController
  # @route greeting
  def greeting
  end
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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.
