A mostly functional DataMapper adapter for MongoDB.
4 specs are not passing, to do with OR conditions or negated regular expressions.
Updating on Serial is also broken when Serial field is not called '_id'. So call Serial field '_id', OK?
gem install mongodb_adapter
adapter: mongodb database: databasename host: hostname # defaults to 'localhost' port: portnum # defaults to 27017
Uses the 'mongo' gem. For extra performance you should install the 'mongo_ext' gem which adds native compiled components.
