class Attendance < ActiveRecord::Base
  belongs_to :user,counter_cache: true
  belongs_to :event,counter_cache: true

  validates :terms_of_service,:acceptance => true
end

这是我的工厂：

factory :attendance do
    user
    event
    terms_of_service true
  end

这是我的测试：

describe "event has many attendances" do
    it "should have attendances" do
      event = FactoryGirl.create(:event)
      user1 = FactoryGirl.create(:user,firstname: "user1",email: "mail@user2.nl")
      user2 = FactoryGirl.create(:user,firstname: "user2",email: "mail@user1.nl")

      attendance1 = FactoryGirl.create(:attendance,event: event,user: user1,terms_of_service: true)    
    end
  end

这不应该带来任何错误,但确实如此.
