使用带有mongoid的factory_girl来测试referenced_in/references_many

Question

我正在尝试为订阅服务测试相关文档.每个订阅都嵌入在一个帐户中并引用一个计划.以下是各种代码:

帐户:

Factory.define :account, :class => Account do |a|
  a.subdomain 'test'
  a.agents { [ Factory.build(:user) ] }
  a.subscription { Factory.build(:free_subscription) }
end

订阅:

Factory.define :free_subscription, :class => Subscription do |s|
  s.started_at Time.now
  s.plan { Factory.build(:free_plan) }
end

计划:

Factory.define :free_plan, :class => Plan do |p|
  p.plan_name 'Free'
  p.cost 0
end

错误:

Mongoid::Errors::InvalidCollection: Access to the collection for Subscription is not allowed since it is an embedded document, please access a collection from the root document.

如果我注释掉将计划链接到订阅的行,那么测试就可以工作,但显然我无法测试订阅是否有计划.

任何建议将不胜感激.

更新:

以下是模型:

class Account
  include Mongoid::Document

  field :company_name, :type => String
  field :subdomain, :type => String
  field :joined_at, :type => DateTime

  embeds_one :subscription

  accepts_nested_attributes_for :subscription

  before_create :set_joined_at_date

  private

  def set_joined_at_date
    self.joined_at = Time.now
  end
end

class Subscription
  include Mongoid::Document

  field :coupon_verified, :type => Boolean
  field :started_at, :type => DateTime

  referenced_in :plan
  embedded_in :account, :inverse_of => :subscription
end

class Plan
  include Mongoid::Document

  field :plan_name, :type => String
  field :cost, :type => Integer
  field :active_ticket_limit, :type => Integer
  field :agent_limit, :type => Integer
  field :company_limit, :type => Integer
  field :client_limit, :type => Integer
  field :sla_support, :type => Boolean
  field :report_support, :type => Boolean

  references_many :subscriptions
end

Answer 1

您需要创建一个订阅帐户才能生效.

Factory.define :free_subscription, :class => Subscription do |s|
  s.started_at Time.now
  s.plan { Factory.build(:free_plan) }
  s.account { Factory(:account) }
end
