## railsbug.sh
This is a bug where a model with a `url` attribute gets it modified when a controller is returning a JSON response

as_json response: [{"id"=>1, "title"=>"Hello 1", "url"=>"http://www.hello.com", "created_at"=>Tue, 12 Jan 2016 04:12:22 UTC +00:00, "updated_at"=>Tue, 12 Jan 2016 04:12:22 UTC +00:00}, {"id"=>2, "title"=>"Hello 2", "url"=>"http://www.hello.com", "created_at"=>Tue, 12 Jan 2016 04:12:29 UTC +00:00, "updated_at"=>Tue, 12 Jan 2016 04:12:29 UTC +00:00}]
JSON response in browser: [{"id":1,"title":"Hello 1","url":"http://localhost:3000/stories/1.json"},{"id":2,"title":"Hello 2","url":"http://localhost:3000/stories/2.json"}]
