Class DataItem
In: vendor/plugins/services/lib/data_item.rb
Parent: ActiveRecord::Base

This is the the ActiveRecord model that represents data items. A bunch of convienence methods will be added here to help DataService do its job. Of course, this means that DataService will absolutely not be able to run outside of Rails. At least not without some hack.

Methods

Public Class methods

findDataByGrouping(groupID, dataType = nil, order = :desc)
