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

当我运行我的测试时,我收到此错误.

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

而且为了完整性,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
