CouchDB accessing composed column


In my RoR application, I am using Couchrest_model to access a CouchDB database.

I have a model which represents an scientific Article. I am going to simplify my model to explain it better. An article can have a title, a year and one or more authors.

In the couchDB database, an article can be represented like this:

article {   title = "abc",   year = "2012",   author = {      name = Paulo,      age = 34   } }

(In the case the article only have an author)


article {   title = "abc",   year = "2012",   author = {     [0] {        name = "Paulo",        age = "34"     }     [1] {        name = "Philippe",        age = "32"     }   } }

class Article < CouchRest::Model::Base   property :title   property :year   property :author end

In the case my article have only one author, I can access author's information (name and age) like this:

But, how can I access the information of authors if the article have more than 1 author?
