工厂女孩,依赖工厂

Question

UPDATE

我回去使用Fixtures.IMOP,固定装置比工厂更好; 更容易使用,更容易理解,更容易理解(没有魔力).我的建议:将测试库限制为非常基础(听DHH)...使用minitest和灯具.

在我的应用程序中,一个区有很多学校,一个学校有很多用途,一个用户有很多帐户,一个帐户有一个角色.为了创建完整的测试工厂,我需要创建一个贯穿工厂的用户和学校.我在最近的尝试中得到了"堆栈级太深"的错误.

我的user_test.rb

 FactoryGirl.define do

   factory :district do
     name "Seattle"
   end

   factory :school do
     association :primarycontact, factory: :user # expecting this to attach the user_id from factory :user as :primary contact_id in the school model
     association :district, factory: :district # expecting this to attach the :district_id from the :district factory as :district_id in the school model
     name "Test School"
   end

   factory :user do, aliases: [:primarycontact]
     email "adam@example.com"
     name "Who What"
     username "wwhat"
     password "123456"
     password_confirmation { |u| u.password }
     association :school, factory: :school # expecting this to create :school_id in the users model, using the :school factory
   end

   factory :role do
     name "student"
   end

   factory :account do
     association :user, factory: :user
     association :role, factory: :role
   end

 end

所以,我正在尝试做FactoryGirl.create(:account)...一些我期望创建一个帐户,其中包括上述工厂的用户和角色,用户与该学区相关联的用户.这不适合我.在失败的测试中,我得到"堆栈级太深"的错误.并且,我相信我在每个DatabaseCleaner.clean之前在每个新工厂之前清除测试数据库.

调用这些工厂的测试是:

describe "User integration" do

  def log_em_in
    visit login_path
    fill_in('Username', :with => "wwhat")
    fill_in('Password', :with => "123456")
    click_button('Log In')
  end

  it "tests log in" do
    user = FactoryGirl.create(:account)
    log_em_in
    current_path.should == new_user_path
  end

end

.

current_path.should == new_user_path returns unknown method error 'should'

如何改进此代码以正确嵌套工厂并获取current_user以继续测试？

楷模

school.rb

  belongs_to :district
  belongs_to :primarycontact, :class_name => "User"
  has_many :users, :dependent => :destroy

user.rb

  belongs_to :school
  has_many :accounts, :dependent => :destroy

district.rb

  has_many :schools

account.rb

  belongs_to :role
  belongs_to :user

role.rb

  has_many :accounts
  has_many :users, :through => :accounts

Answer 1

您的基本问题是您的user工厂和school工厂之间存在循环依赖关系,这是因为您primarycontact在创建学校时创建了(用户),然后该用户创建了学校,等等.

您可以通过更改school在user工厂内定义关联的方式来解决此问题.在此之前,我建议使用关联的简写符号作为一般规则.所以替换这个:

factory :account do
  association :user, factory: :user
  association :role, factory: :role
end

有了这个:

factory :account do
  user
  role
end

使用这种简化,以下工厂将执行您想要的操作而不会产生任何循环依赖:

FactoryGirl.define do

  factory :district do
    name "Seattle"
  end

  factory :school do |school|
    district
    primarycontact
    name "Test School"
    after_build do |s|
      s.primarycontact.school = s
    end
  end

  factory :user do
    email "adam@example.com"
    name "Who What"
    username "wwhat"
    password "123456"
    password_confirmation { |u| u.password }
    school
  end

  factory :primarycontact, class: "User" do
    # add any attributes you want the primarycontact user to have here
  end

  factory :role do
    name "student"
  end

  factory :account do
    user
    role
  end

end

请注意,我所做的是primarycontact使用该class: "User"选项创建工厂.与user工厂不同,此工厂school默认情况下不创建,避免循环依赖.

然后在school工厂里,我使用after_build回调将学校本身分配给school协会primarycontact,而不是创建一所新学校(这导致了你工厂的问题).

希望有道理.请注意,更新版本的factory_girl中的回调语法已更改,有关详细信息,请参阅文档.
