couchrest_model/spec/couchrest/more/extended_doc_view_spec.rb
Brian Candler c4b49baecf ClassProxy provides class-level methods on a dynamically chosen database.
Examples:

  db = CouchRest::Database.new(...)
  articles = Article.on(db)

  articles.all { ... }
  articles.by_title { ... }

  u = articles.get("someid")

  u = articles.new(:title => "I like plankton")
  u.save    # saved on the correct database
