Question

好吧，伙计们。这怎么有意义呢？两个嵌套工厂（被FactoryGirl视为继承）不应相互冲突。到底他妈发生了什么？它不是继承，也不是。我不知道为什么他们称之为继承，如果不是。我只是做错了吗？（注意f.account_type）

看看下面的工厂定义。

factory :partner do |f|
  f.company_name { Faker::Company.name }
  f.username { Faker::Internet.user_name }
  f.password { Faker::Internet.password }
  f.password_confirmation { password }
  f.pid { Faker::Lorem.word }

  f.association :primary_contact

  # Inherited
  factory :business_partner do
    f.account_type "business"
    f.tax_id { Faker::Company.duns_number }
  end

  # Inherited
  factory :personal_partner do
    f.account_type "personal"
    f.ssn { Faker::Company.duns_number }
  end

end

当我运行测试时，我收到此错误。

Failure/Error: partner = FactoryGirl.create(:business_partner)
  FactoryGirl::AttributeDefinitionError:
    Attribute already defined: account_type

只是为了完整性，我的规格。

# spec/models/partner.rb
require 'spec_helper'
require 'pp'

describe Partner do

  it "has a valid factory" do
    partner = FactoryGirl.create(:business_partner)
    partner.should be_valid
    puts partner
  end

  it "is invalid without a firstname" do
#    FactoryGirl.build(:partner_contact, first_name: nil).should_not be_valid
  end

  it "is invalid without a lastname" do
#    FactoryGirl.build(:partner_contact, last_name: nil).should_not be_valid
  end

  it "is invalid without an email address" do
#    FactoryGirl.build(:partner_contact, email: nil).should_not be_valid
  end

  #it "returns a contact's fullname as a string"

end

在business_partner和personal_partner工厂定义中，您指的是f，这是partner工厂的定义。这意味着，即使account_type定义出现在子工厂中，两者都在父工厂中定义。

在较新版本的FactoryGirl中解决此问题的最简单方法是完全删除阻止参数。

factory :partner do
  company_name { Faker::Company.name }
  username { Faker::Internet.user_name }
  password { Faker::Internet.password }
  password_confirmation { password }
  pid { Faker::Lorem.word }

  association :primary_contact

  # Inherited
  factory :business_partner do
    account_type "business"
    tax_id { Faker::Company.duns_number }
  end

  # Inherited
  factory :personal_partner do
    account_type "personal"
    ssn { Faker::Company.duns_number }
  end
end

如果您喜欢块参数，只需确保接受每个工厂定义的参数并使用不同的变量名称。
