Introduction

Small library to add DataMapper style resources for MongoDB.

class ExampleResource
  include Mordor::Resource

  attribute :first, :index => true
  attribute :second
  attribute :third, :finder_method => :find_by_third_attribute
  attribute :at,    :timestamp => true
end

This adds attr_accessors to the ExampleResource for each attribute, plus adds finder methods of the form find_by_{attribute}. The naming convention can be overridden by using the optional :finder_method option, as can be seen with the third attribute.

When the :index => true option is set, indices are ensured before each query on the collection. Indices are descending by default, but this can be changed by also supplying a :index_type => Mongo::ASCENDING option.

At most one attribute per Resource can have the option :timestamp => true set. This means that the attribute will be saved as one of the two first attributes (the other one being the _id attribute. When no value is given for the timestamped attribute, a timestamp with value 0 will be inserted, which results in a timestamp being assigned to it by the MongoDB. An exception is raised when more than one attribute is given the timestamp option
