使用工厂女孩创建HABTM协会

Question

我一直在努力几个小时，让工厂女孩创建两个工厂 - 一个用于用户，一个用于组织。

但我似乎并没有理解我如何在工厂中反映'has_and_belongs_to_many'关系，只要我尝试创建组织并将其与管理员用户关联，我会遇到各种错误消息（具体取决于我使用的方法）。 我的模型似乎工作正常，我的种子文件填充开发数据库，​​并创建所有的关联。

现在我的文件是这样的：

用户工厂

FactoryGirl.define do 

    factory :user do 
    email 'example@example.com' 
    password 'password' 
    password_confirmation 'password' 
    after(:create) {|user| user.add_role(:user)} 

    factory :owner do 
     after(:create) {|user| user.add_role(:owner)} 
    end 

    factory :admin do 
     after(:create) {|user| user.add_role(:admin)} 
    end 

    factory :superadmin do 
     after(:create) {|user| user.add_role(:superadmin)} 
    end 
    end 
end 

组织工厂

FactoryGirl.define do 

    factory :organization do |f| 
    f.name "example" 
    f.website "www.aquarterit.com" 
    f.association :users, :factory => :admin 
    end 
end 

在我的规格

我测试：

describe Organization do 


    it "has a valid factory" do 
    FactoryGirl.create(:organization).should be_valid 
    end 

    it "is invalid without a name" do 
    FactoryGirl.build(:organization, name: nil).should_not be_valid 
    end 

    it "is associated with at least one admin user" do 
    FactoryGirl.create(:organization) 
    it { should have_and_belong_to_many(:users)} 
    end 

end 

所有三个测试是失败的，这里的错误消息：

1) Organization has a valid factory 
    Failure/Error: FactoryGirl.create(:organization).should be_valid 
    NoMethodError: 
     undefined method `each' for #<User:0x007fadbefda688> 
    # ./spec/models/organization_spec.rb:7:in `block (2 levels) in <top (required)>' 

    2) Organization is invalid without a name 
    Failure/Error: FactoryGirl.build(:organization, name: nil).should_not be_valid 
    NoMethodError: 
     undefined method `each' for #<User:0x007fadc29406c0> 
    # ./spec/models/organization_spec.rb:11:in `block (2 levels) in <top (required)>' 

    3) Organization is associated with at least one admin user 
    Failure/Error: organization = FactoryGirl.create(:organization) 
    NoMethodError: 
     undefined method `each' for #<User:0x007fadc2a3bf20> 
    # ./spec/models/organization_spec.rb:15:in `block (2 levels) in <top (required)>' 

任何帮助是一如既往非常感谢！

更新

在理论，分配角色的用户应分配一个管理员对组织工作的工作原理是一样的。但是，如果我改变organizations.rb到

FactoryGirl.define do 

    factory :organization do 
    name "example" 
    website "www.aquarterit.com" 
    after(:create) {|organization| organization.add_user(:admin)} 
    end 
end 

我得到以下错误（我有宝石早该安装）：

1) Organization is associated with at least one admin user 
    Failure/Error: it { should have_and_belong_to_many(:users)} 
    NoMethodError: 
     undefined method `it' for #<RSpec::Core::ExampleGroup::Nested_1:0x007ff2395f9000> 
    # ./spec/models/organization_spec.rb:16:in `block (2 levels) in <top (required)>' 

Answer 1

看起来你没有正确分配users并没有正确创建:admin用户。为此，您需要将一组用户分配到organization.users。而且，您需要使用User实例填充该阵列（假定您有User工厂，名称为:admin）。

factory :organization do 
    name "example" 
    website "www.aquarterit.com" 
    after(:create) {|organization| organization.users = [create(:admin)]} 
end 

Answer 2

我这样做，这样一来，问题和测试有一个HABTM关系，以便：

FactoryGirl.define do 
    factory :question do 
    question 'Some stupid question' 
    user nil 
    factory :question_with_test do 
    # factory_girl's dynamic attributes, ignore it and pass it to evaluator 
    transient do 
     test nil 
    end 

    after(:create) do |question, evaluator| 
     create(:question_tests, question: question, test: evaluator.test) 
    end 
    end 
    end 
end 

现在我可以创建HABTM到测试模型中的问题：

let(:test)    { FactoryGirl.create :test, user: user } 
let(:question_test_1) { FactoryGirl.create :question_with_test, user: user, test: test } 

的question_tests工厂是非常基本的：

FactoryGirl.define do 
    factory :question_tests, class: 'QuestionTest' do 
    question 
    test 
    end 
end
