使用factorygirls模型embeds_many和embedded_in关系

Posted 2021-03-30

我想写FactoryGirl类来创建公司。模型如下：

module Company
  class Contact
    include Mongoid::Document
    include ActiveModel::Validations

    embedded_in :company, class_name: "::Company::Contact"

  end
end

module Company
  class Company

    require 'autoinc'

    embeds_many :contacts, class_name: "::Company::Contact"

  end
end


FactoryGirl.define do
  factory :company, :class => 'Company::Company' do
    name { Faker::Company.name }

    after(:create) do |company|
      # company.contacts << create(:company_contact)
      create_list(:company_contact, 1, company: company)
    end
    # contacts { [ build(:company_contact) ] }
  end
end

收到的错误是

失败/错误：create_list（：company_contact，1，company：company）

 Mongoid::Errors::InvalidPath:

   message:
     Having a root path assigned for Company::Contact is invalid.
   summary:
     Mongoid has two different path objects for determining the location of a document in the database, Root and Embedded. This error is raised when an embedded document somehow gets a root path assigned.
   resolution:
     Most likely your embedded model, Company::Contact is also referenced via a has_many from a root document in another collection. Double check the relation definitions and fix any instances where embedded documents are improperly referenced from other collections

我该怎么处理？我无法改变模型。

答案

您的关联类名称错误：

module Company
  class Contact
    include Mongoid::Document
    include ActiveModel::Validations

    embedded_in :company, class_name: 'Company::Company'
  end
end
