Rspec + Shoulda + FactoryGirl = 未定义方法 `reflect_on_association'

Question

我有 Rspec + Shoulda + FactoryGirl，在尝试调用 Shoulda 的 have_many 或 belongs_to 方法时收到以下错误。 “验证”组中使用的所有 Shoulda 方法都可以正常工作：

提前致谢

spec/spec_helper.rb

require 'shoulda'

spec/models/project_spec.rb

require File.dirname(__FILE__) + '/../spec_helper'

describe "A Project" do
  describe "associations" do

    subject { Factory(:project) }

    it { should have_many(:tasks) }
    it { should belong_to(:project_status) }
  end

  describe "validations" do
    subject { Factory(:project) }

    it { should validate_presence_of(:name) }

    it { should validate_uniqueness_of(:name).case_insensitive }

    it { should allow_mass_assignment_of(:name) }
  end
end

感谢 David C. 指出应该显而易见的内容。我有一个多余的 active_matchers 插件，它与 shoulda 冲突。
