view db/migrate/104_add_projects_lft_and_rgt.rb @ 737:1ce6efe3db0e feature_318

Last "fix" was completely bogus. Here's a real one (for situation where URL has nothing beyond the location)

class AddProjectsLftAndRgt < ActiveRecord::Migration
  def self.up
    add_column :projects, :lft, :integer
    add_column :projects, :rgt, :integer
  end

  def self.down
    remove_column :projects, :lft
    remove_column :projects, :rgt
  end
end
