Changed Enumerations to use a Single Table Inheritance * Added migrations to change Enumerations to an STI relationship * Added TimeEntryActivity model (STI) * Added DocumentCategory model (STI) * Added IssuePriority model (STI) * Added Enumeration#get_subclasses to get a list of the subclasses of Enumeration * Changed Enumeration to use the STI type field instead of the opt field * Changed Enumeration#opt to return the old opt values but with a deprecation warning. * Removed Enumeration::OPTIONS * Removed the dynamic named_scopes in favor of specific named_scopes. Kept for compatibility reasons. * Added Enumeration#default so each subclass can easily find it's default record. * Fixed Enumeration#default to use the STI scoping with a fake default scope for finding Enumeration's default. * Added a 'all' named scope for getting all records in order by position. * Added Deprecation warnings to the old named_scopes in Enumerations. * Moved various methods off of Enumeration and onto the concrete classes * Changed the EnumerationsController to use types * Updated the Enumeration list template * Added has_many relationships to the Enumeration STI classes. * Fixes for tests. #3007 git-svn-id: svn+ssh://rubyforge.org/var/svn/redmine/trunk@2777 e93f8b46-1217-0410-a6f0-8f06a7374b81 2009-05-31 01:30:36 +02:00			`class UpdateEnumerationsToSti < ActiveRecord::Migration`
