具有多态关联的Rails 4.2.6 FactoryGirl

Question

我在为我与FactoryGirl的多态关联设置工厂时遇到了问题。我的模型和出厂设置如下所示：

class Address < ActiveRecord::Base
  belongs_to :addressable, polymorphic: true
end

class Customer < ActiveRecord::Base
  has_one :address, as: :addressable
end 

factory :address do
      village Faker::Address.city
      upazilla Faker::Address.street_name
      ward Faker::Address.street_address
      district Faker::Address.state
      association :addressable
end


factory :customer ,class: Customer do 
      recharge_token 10 
      date_of_birth Faker::Date.backward(100)
      manager
      after(:create) do |customer| 
         customer.address = create(:address, addressable: customer)
        #create( :address, addressable: customer)
      end     
end

测试套件中断，并显示以下错误消息

 vendor/cache/ruby/2.2.0/gems/factory_girl-4.7.0/lib/factory_girl/linter.rb:12:in `lint!': The following factories are invalid: (FactoryGirl::InvalidFactoryError)
 * address - Factory not registered: addressable (ArgumentError)

This正是我的问题，但不幸的是，他的解决方案对我不起作用。感谢大家抽出时间来！

Answer 1

显式指定工厂：

factory :address do
   association :addressable, factory: :customer
end

或者在after create列表中的另一个模型上创建关联has_one：

factory :customer do 
   after(:create) do |customer| 
     customer.address = create(:address, addressable: customer)
   end
end
