具有多态 has_many 关联的 Factory Girl答案

【问题标题】：Factory Girl with polymorphic has_many association具有多态 has_many 关联的 Factory Girl
【发布时间】：2013-05-01 04:35:11
【问题描述】：

我正在尝试使用新语法建立一个带有多态关联的 factorygirl has_many 关联。这是代码。它没有正确构建地址并将其与站点关联。

class Address < ActiveRecord::Base

  belongs_to :addressee, :polymorphic => true

end

class Site < ActiveRecord::Base

  has_many addresses, :as => :addressee, :dependent => :destroy

end

***** FACTORYGIRL ******


FactoryGirl.define do
    factory :address, class: 'Address' do
        property_type "House"
        street_number "31"
        street_type "STREET"
        suburb "XXXXX"
        postcode "XXXX"
    end

    factory :site_address, class: 'Address' do
        property_type "House"
        street_number "31"
        street_type "STREET"
        suburb "XXXX"
        postcode "XXXX"
        site
    end
end


FactoryGirl.define do

    factory :site, class: 'Site' do
        name "MyString"
        organisation_category nil
        service_type_organisation_category_id 1
        telephone "MyString"
        fax "MyString"
        email "MyString"
        url "MyString"
        clinical_software_package_id 1
        billing_software_package_id 1
        bulk_billing false
        disabled_access false
        ncacch false
        parking false
        organisation nil

        factory :site_with_addresses do
            ignore do
                address_count 1
            end

            after (:create) do |site,evaluator|
                FactoryGirl.create_list(:site_address, evaluator.address_count, addressee: site)
            end
        end

    end


end

【解决方案1】：

你还没有在工厂内声明关联地址，试试

factory :address, class: 'Address' do
    property_type "House"
    street_number "31"
    street_type "STREET"
    suburb "XXXXX"
    postcode "XXXX"
    association :addressee, :factory => :site
end

【讨论】：

我猜这行不通。因为他没有工厂叫addressee。 If the factory name is the same as the association name
大家好，gist.github.com/emilevictor/a376231cf11345b35e1b 这是我的网站工厂的 factorygirl 资源。我以为我已经包含了它，但我不小心包含了 :address 工厂。相关代码是:site_address 和:site。我当前使用的方法（如网站上所示）是错误的。
这对我来说非常有效。 FactoryGirl 似乎理解 :addressee 是一个多态关联，并且它正确设置了 Address 对象的 :addressee_id 和 :addressee_type 属性。

【解决方案2】：

这个要点可能会有所帮助 - https://gist.github.com/travisr/2830535/

class Alert < ActiveRecord::Base
  belongs_to :alertable, :polymorphic => true
end


class Region < ActiveRecord::Base
  has_many :alerts, :as => :alertable
end


FactoryGirl.define do
  Factory.define :alert do |alert|
    alert.alertable { |a| a.association(:region) }
  end
end
