RestfulError
Define your error with status code. Raise it and you will get formatted response with i18nized message.
Installation
Add this line to your application's Gemfile:
gem 'restful_error'
And then execute:
$ bundle
Load the module in your controller:
class ApplicationController < ActionController::Base
include RestfulError::ActionController
Usage
Simple
raise me
class PostsController < ApplicationController
before_action do
raise RestfulError[401] unless current_user
# or
raise RestfulError::Unauthorized unless current_user
end
end
Multi format response
get '/posts/new'
#=> render 'restful_error/show.html' with @status_code and @message
post '/posts.json'
#=> { status_code: 401, message: "Sign in required"} or write your json at 'restful_error/show.json'
get '/session.xml'
#=> "<error><status_code type="integer">401</status_code><message>Sign in required</message></error>" or write your xml at 'restful_error/show.xml'
