RSpec/FactoryGirl - MongoID 嵌入文档不持久

Question

拥有以下工厂：

FactoryGirl.define do
  factory :user do
    provider "github"
    sequence(:uid) {|n| "111111#{n}"}
    sequence(:name) {|n| "name#{n}"}
    sequence(:email) {|n| "name#{n}@example.com"}
    sequence(:nickname) {|n| "nick#{n}"}
    sequence(:token) {|n| "111111111111111111111111111111111111111#{n}"}
    watchlists { [ FactoryGirl.build(:watchlist) ] }
  end
  factory :watchlist do
      sequence(:html_url) {|n| "https://github.com/user#{n}/repo#{n}"}
      description "One repo description"
      sequence(:forks) {|n| "1#{n}"}
      sequence(:watchers) {|n| "#{n}"}
      created_at "2012-11-21 00:09:12 UTC"
      pushed_at "2010-04-15 21:11:51 UTC"
      avatar_url "https://avatar.example.com/avatar.png"
  end
end

当我像下面这样创建工厂时：

let(:user) { FactoryGirl.create :user }

它导致 :user only 持久模型，没有嵌入的子模型 :watchlist :

我怎样才能让嵌入式 mongoid 模型也保持不变？

Answer 1

应该是持久化的，但是需要查询关系。

试试：

User.first.watchlists

或者在 MongoDB shell 中，整个文档会像你期望的那样打印出来 db.users.find().pretty();
