view db/migrate/073_add_enumerations_is_default.rb @ 420:2008fa7fda29 bug_145

Track the project tree explicitly through recursive functions rather than using lft, rgt ordering.  Fixes #145

class AddEnumerationsIsDefault < ActiveRecord::Migration
  def self.up
    add_column :enumerations, :is_default, :boolean, :default => false, :null => false
  end

  def self.down
    remove_column :enumerations, :is_default
  end
end
