【问题描述】：

我的模型；家庭 has_many :neighbors 和 Neighbor belongs_to :household

每个家庭必须有一个邻居：

   validates :neighbors, presence: {message: 'You must enter at least one neighbor']

我正在尝试创建一个工厂

   factory :household, class:  "Household" do
     household_name "Brooke"
     neighbor
   end


   factory :neighbor, class: "Neighbor" do
     first_name "Tom"
     last_name "Brooke"
   end 

    it "has a valid factory"  do
      household = create(:household, neighbors: :neighbor)
      expect(household).to be_valid
    end

这给了我：

  undefined method `neighbor=' for #<Household:0x007fd45ec85138>

如何成立Factory Girl来体现协会？

【解决方案1】：

我终于做到了：

我把邻居带出了家庭工厂：

  factory :household, class:  "Household" do
      household_name "Brooke"
    end

对于我的测试，我在测试中创建了关联：

   it "has a valid factory"  do
      neighbor = create(:neighbor)
      household = create(:household, neighbors: [neighbor])
      expect(household).to be_valid
   end
