view db/migrate/048_allow_null_version_effective_date.rb @ 610:e9274ba9c1b3 feature_36

Fixes Bug #272 - the toggle author button calls button_to_remote instead of button_to, which does not have a type="submit" tag. Minor interface changes.

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
