ruby-on-rails – 我是否正确使用工厂？

发布时间：2020-12-17 03:01:07 所属栏目：百科来源：网络整理

导读：这是我目前的测试设置： # spec/factories.rbrequire 'factory_girl'FactoryGirl.define do # Roles factory :user_role,:class = Role do name 'User' end # Users factory :user,:class = User do sequence(:email) {|n| "email#{n}@example.com" } passwo

这是我目前的测试设置：

# spec/factories.rb
require 'factory_girl'

FactoryGirl.define do
  # Roles

  factory :user_role,:class => Role do
    name 'User'
  end

  # Users
  factory :user,:class => User do
    sequence(:email) {|n| "email#{n}@example.com" }
    password 'password'
    password_confirmation 'password'
    name 'Yuri Userington'
    roles { |a| [a.association(:user_role)] }
  end

  # Instruments
  factory :instrument,:class => Instrument do
    title "Doobie Doo Instrument Title"
    is_valid true
    association :user,:factory => :user
  end

  # Sequences
  sequence :email do
    "email#{n}@factory.com"
  end

end

# spec/controllers/instruments_controller_spec.rb
require 'spec_helper'

describe InstrumentsController do

  before (:each) do
    @instrument = FactoryGirl.create(:instrument)
    @attr = FactoryGirl.attributes_for(:instrument)
    @user = FactoryGirl.create(:user)
  end

  describe "GET index" do
    it "assigns all instruments as @instruments" do
      instrument = Instrument.new(@attr)
      instrument.user = @user 
      instrument.save!
      get :index
      assigns(:instruments).should eq([instrument])
    end 
  end

end

结果是,当我运行我的测试时,我的输出中出现以下错误：

Failures:

  1) InstrumentsController GET index assigns all instruments as @instruments
     Failure/Error: @instrument = FactoryGirl.create(:instrument)
     ActiveRecord::RecordNotFound:
       Couldn't find Role with id=2
     # ./app/models/user.rb:21:in `assign_role_after_sign_up'
     # ./spec/controllers/instruments_controller_spec.rb:24:in `block (2 levels) in <top (required)>'

基于此,似乎我的：用户工厂中的角色关联调用没有被调用 – 我在这里做错了什么？我是以完全错误的方式使用它吗？

谢谢！！

解决方法

这里有很多话要说.将您的代码与以下内容进行比较,以查看删除了多少行或单词.

FactoryGirl.define do
  # Sequences
  sequence :email do |n|
    "email#{n}@factory.com"
  end

  # Roles
  factory :user_role,:class => Role do
    name 'User'
  end

  # Users
  factory :user do
    email
    password 'password'
    password_confirmation 'password'
    name 'Yuri Userington'
    roles { |user| [Factory(:user_role)] } #many to many
   end

  # Instruments
  factory :instrument,:class => Instrument do
    title "Doobie Doo Instrument Title"
    is_valid true
    association :user #one-to-one or one-to-many
  end

end

在你的测试中：

describe InstrumentsController do

  before (:each) do
    @user = Factory(:user)
  end

  describe "GET index" do
    it "assigns all instruments as @instruments" do
      instrument = Factory(:instrument,:user => @user)
      get :index
      assigns(:instruments).should eq([instrument])
    end 
  end

end
