view db/migrate/083_add_messages_sticky.rb @ 420:2008fa7fda29 bug_145

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

class AddMessagesSticky < ActiveRecord::Migration
  def self.up
    add_column :messages, :sticky, :integer, :default => 0
  end

  def self.down
    remove_column :messages, :sticky
  end
end
