view db/migrate/092_change_changes_from_revision_to_string.rb @ 420:2008fa7fda29 bug_145

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

class ChangeChangesFromRevisionToString < ActiveRecord::Migration
  def self.up
    change_column :changes, :from_revision, :string
  end

  def self.down
    change_column :changes, :from_revision, :integer
  end
end
