将Rails从3.0.1升级到3.0.7后用于classy_enum的TypeError

Question

我刚刚在我的开发mac上将rails从3.0.1升级到3.0.7。已尝试运行rspec (2.6.0) (使用factory_girl_rails 1.0.1)，但在模型使用classy_enum (0.9.1) gem进行状态实现的所有测试中都出现错误。Rails本身运行没有问题，但rspec测试失败。不知道是什么导致了错误。

这里的确切错误是：

1) Billboard should create a new instance given valid attributes
      Failure/Error: @etype = Factory(:etype)
      TypeError:
          Cannot visit EtypeGroupActivity
   # ./spec/models/billboard_spec.rb:6:in `block (2 levels) in <top (required)>'

Etype模型代码：

class Etype < ActiveRecord::Base
  attr_accessible :code, :group, :order, :logo
  classy_enum_attr :group, :enum => :etype_group
  delegate :group_name, :to => :group

Etype_group枚举代码：

class EtypeGroup < ClassyEnum::Base
  enum_classes :event, :event_session, :activity, :venue, :venue_space
  def group_name
    ""
  end
end

class EtypeGroupEvent < EtypeGroup
  def group_name
    I18n.t('etypes.groups.event')
  end
end

更新：

billboard_spec代码为：

require 'spec_helper'

describe Billboard do
  before(:each) do
    @user = Factory(:user)
    @etype = Factory(:etype)
    @attr = { :title    => "First Keynote",
              :etype_id => @etype,
              :summary  => "This keynote will open our event" }
  end

  it "should create a new instance given valid attributes" do
    @user.billboards.create!(@attr)
  end
end

在factories.db中，我有：

Factory.define :etype do |etype|
  etype.code                 "keynote"
  etype.group                "activity"
  etype.order                10
end

问题已从ClassyEnum version 1.0.0开始解决
