Topic: Model definition using couchDB (or another NoSQL DB)

Hello

I am writing a RoR application which connects to a noSQL database
(couchDB).


In the database, I have an author document. The author has a first_name
and a last_name. It also have inside another document: a book. The book
has a title and a year of publication.

Example:

{
  author {
    "first_name" : "abc",
    "last_name"  : "def"
    "book" {
      "title" : "the jungle book",
      "year"  : "1922"
    }
  }
}

I am trying to define the Author model file so I can access Author's
information as so related book information:

class Author < CouchRest::Model::Base

  property :first_name
  property :last_name
  property :book

  ...
end

However, when in the HTML file I try to access to the book author's
information, I get errors.

HTML example:

<td><%=h author.first_name %> <%=h author.last_name %> <%=h
author.book.title %></td>

The error I get is:
undefined method `title' for :book:Symbol


It's the first time I am developing a RoR application using a CouchDB
application, so I am pretty sure that the problem comes from the way I
am defining the Author's model file.

Can anyone help me about that?

Thank you
