view db/migrate/061_add_roles_builtin.rb @ 420:2008fa7fda29 bug_145

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

class AddRolesBuiltin < ActiveRecord::Migration
  def self.up
    add_column :roles, :builtin, :integer, :default => 0, :null => false
  end

  def self.down
    remove_column :roles, :builtin
  end
end
