Rspec + Shoulda + FactoryGirl =未定义的方法`reflect_on_association'

Question

我有Rspec + Shoulda + FactoryGirl，并且在尝试调用Shoulda的have_many或belong_to方法时收到以下错误。在 “验证” 组，做工精细使用的所有早该方法：

在此先感谢

规格/ spec_helper.rb

require 'shoulda' 

规格/型号/ 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.指出了本该显而易见的事情。我有一个与shoulda冲突的冗余active_matchers插件。
