annotate db/migrate/.svn/text-base/048_allow_null_version_effective_date.rb.svn-base @ 760:b2a9e64b8283 feature_14

Fixes Bug #322, but is not self-contained in the plugin (basically I'm editing the original projects controller…)

class AllowNullVersionEffectiveDate < ActiveRecord::Migration
  def self.up
    change_column :versions, :effective_date, :date, :default => nil, :null => true
  end

  def self.down
    raise IrreversibleMigration
  end
end
