Mongoid，子模型没有创建

Question

我有两个模型 Owner 和 Shop:

class Owner
  include Mongoid::Document
  include Mongoid::Timestamps

  # Fields
  field :name, type: String

 # Associations
  has_many :shops, dependent: :destroy

  accepts_nested_attributes_for :shops


  # Validations
  validates_presence_of :name

end

class Shop
  include Mongoid::Document
  include Mongoid::Timestamps

   # Fields
  field :name, type: String
  field :address, type: String

  belongs_to :owner

  # Validations
  validates_presence_of :name, :address, :owner

end

现在我尝试创建所有者

2.times do
  owner = Owner.create(name: Faker::Name.name)
  owner.save

   3.times do
    shop = Shop.create
    shop.name = Faker::Company.name
    shop.owner = owner
    shop.address = "#{Faker::Address.street_address} #{Faker::Address.building_number}"
    shop.save
   end
   owner.save
end

当我开始这个的时候。它创建所有者但不创建其商店。不知道为什么？

Answer 1

由于验证而未创建，请尝试 Shop.new 而不是 Shop.create

2.times do
  owner = Owner.new(name: Faker::Name.name)
  if owner.save!

    3.times do
      shop = Shop.new
      shop.name = Faker::Company.name
      shop.owner = owner
      shop.address = "#{Faker::Address.street_address} #{Faker::Address.building_number}"
      shop.save!
    end
  end       
end
