ruby-on-rails-3 - Has_many 通过使用 factoryGirl

Question

我有这个模型：

class Application < ActiveRecord::Base
  has_many :admin_user_applications, dependent: :destroy
  has_many :admin_users, through: :admin_user_applications, :source => :user, validate: :false
end

class User < ActiveRecord::Base
  has_many :admin_user_applications, dependent: :destroy
  has_many :administrable_applications, through: :admin_user_applications, :source => :application
end

class UserApplication < ActiveRecord::Base
  belongs_to :user
  belongs_to :application
end

我定义了我的应用程序工厂：

FactoryGirl.define do
  factory :application, :class => Application do
    sequence(:name) {|n| "application-#{n}" }
    association :owner, :factory => :user
  end
end

但是当我这样做时：

app_3 = FactoryGirl.create(:application, admin_users: [@user])
puts @user.admin_user_applications.inspect  # =>[] 

它返回我[]

我做错了什么？

Answer 1

尝试

@user.admin_user_applications << FactoryGirl.create(:application)
