多个工厂女孩协会问题

Question

我无法理解如何与 Factory Girl 建立联系。

基本上，Agency 有很多代理人、房东和房产。当我检查我的属性工厂是否有效时，它 returns 错误地说 Account Manager 和 Landlord 不能为空。我如何创建这些关联？创建属性时，它关联 'agency' 并创建其中一个，但我也需要 'Landlord' 和 'Agent' 成为 'agency' 的关联..

部分问题可能是我已经盯着这个看太久了，如果是直截了当的事情，我们深表歉意！

型号：

class Agency < ActiveRecord::Base
  has_many :agents
  has_many :landlords
  has_many :properties
end

class Property < ActiveRecord::Base
  belongs_to :landlord
  belongs_to :agency
  belongs_to :account_manager, class_name: 'Agent', foreign_key: 'agent_id'
end

class User < ActiveRecord::Base
  belongs_to :agency
end

class Agent < User
  has_many :properties
end

class Landlord < User
  has_many :properties
end

工厂：

FactoryGirl.define do
  factory :property do
    address_line_1 "13 Fake Street"
    address_line_2 "Strange Lane"
    town "Fake Town"
    county "FakeCounty"
    post_code "PA0 0WU"
    beds 4
    baths 2
    agency

    factory :invalid_property do
      address_line_1 ""
    end     
  end
end

FactoryGirl.define do     
  factory :agency do
    name "First Agency"
    telephone_number "01993 388388"
    address_line_1 "1 Fake Street"
    town "Fake Town"
    county "FakeCounty"
    post_code "BA1 4GG"
  end
end

FactoryGirl.define do
  factory :agent, class: User do
    first_name "James"
    last_name "Smith"
    email "james.smith@gmail.com"
    password "helloworld"
    telephone_number "01935 222333"
    mobile_telephone_number "07382 928777"
    agency
  end

  factory :landlord, class: User do
    first_name "Bob"
    last_name "Builder"
    email "bob.builder@gmail.com"
    password "helloworld"
    telephone_number "01935 444777"
    agency

    factory :invalid_landlord, class: User do
      first_name ""
    end
  end
end

Answer 1

事实证明，你无法在工厂内部建立这种关系。

最后我删除了关联，首先手动构建代理和任何其他关联，然后将它们传递到工厂的构建中。例如：

  let(:agency) { build(:agency) }
  let(:account_manager) { build(:agent, agency: agency) }
  let(:landlord) { build(:landlord, agency: agency) }
  let(:property) { build(:property, agency: agency, account_manager: account_manager, landlord: landlord ) }
