mongo db

Okay, I woke up this morning (6am) with a need to create a simple reporting dashboard to display the coverage results from OpenCover when it dog-foods its own tests. Now that OpenCover has no **_reported _**bugs, I decided to use my spare time to investigate other technologies for a while. What I needed was simple 'online' storage to capture results from the build system and the ability to extract that data into charts. Normally I'd probably knock up a simple rails app because it is easy to do,

I am using Mongoid [http://mongoid.org/en/mongoid/index.html]to store some data as documents in a MongoDB [http://www.mongodb.org/]database and then run some MapReduce [http://en.wikipedia.org/wiki/MapReduce]queries against the data. Now I have no trouble with mapping data from normal documents and an embedded document but I could not extract data from an embedded collection of documents i.e. class Foo include Mongoid::Document #fields field :custom_id, :type => String #relations
