Question

我正在运行ruby 2.0.0＆amp; Rails 4.0.2

我的模型看起来像：

class Activity < ActiveRecord::Base
    has_many :beneficiaries, -> {includes([:beneficiary_type, :gender])}

    def number_of_beneficiaries(gender, type)
        number = 0

        beneficiaries.each do |b|
            number = b.quantity  if b.gender.name == gender && b.beneficiary_type.name == type
        end

        number
    end
end

失败模型的规范如下：

require 'spec_helper'

describe Activity do
  it "return number of beneficiaries by gender and type" do
    beneficiary_1 = Beneficiary.new(:quantity => 15, :gender => Gender.find_by_name('hombres'), :beneficiary_type => BeneficiaryType.find_by_name('adultos'))
    beneficiary_2 = Beneficiary.new(:quantity => 10, :gender => Gender.find_by_name('mujeres'), :beneficiary_type => BeneficiaryType.find_by_name('niños'))

    activity = Activity.new

    activity.beneficiaries << beneficiary_1
    activity.beneficiaries << beneficiary_2

    expect(activity.number_of_beneficiaries('hombres', 'adultos')).to eq 15
  end
end

这给了我。

1）活动按性别和类型返回受益人数量失败/错误：期望（activity.number_of_beneficiaries（'hombres'，'adultos'））。到eq 15
   expected: 15
        got: 10

   (compared using ==)
 # ./spec/models/activity_spec.rb:30:in `block (2 levels) in <top (required)>'

奇怪的是，如果我颠倒了我指定受益人的顺序，它就会通过测试。

如果我测试预期的受益人数，则正确回答2。

由于声明的顺序，模型规范失败
