Rspec和工廠女孩的Rails麻煩

Question

我試圖解決Rails的問題。這是我的第一個Rails應用程序，我正在對我們未來的項目進行評估。我一直跟隨railstutorial.org一直到第9章，然後試圖自己去做。

使用Rails 3.2.3，Ruby 1.9.3，Factory Girl 1.4.0和rspec 2.10.0。

我遇到的麻煩是客戶端 - [has_many] - >用戶關係。

運行測試時我不能獲得通過的錯誤：

1) User 
    Failure/Error: let(:client) { FactoryGirl.create(:client) } 
    NoMethodError: 
     undefined method `user' for #<Client:0x000000045cbfa8> 

規格/ factories.rb

FactoryGirl.define do 
    factory :client do 
    sequence(:company_name) { |n| "Company #{n}" } 
    sequence(:address) { |n| "#{n} Example Street"} 
    phone "0-123-456-7890" 
    end 

    factory :user do 
    sequence(:name) { |n| "Person #{n}" } 
    sequence(:email) { |n| "person_#{n}@example.com"} 
    password "foobar" 
    password_confirmation "foobar" 
    client 

    factory :admin do 
     admin true 
    end 
    end 

規格/型號/ user_spec.rb

require 'spec_helper' 

describe User do 

    let(:client) { FactoryGirl.create(:client) } 
    before { @user = client.users.build(name: "Example User", 
         email: "user@example.com", 
         password: "foobar", 
         password_confirmation: "foobar") } 

    subject { @user } 

    it { should respond_to(:name) } 
end 

應用/controllers/clients_controller.rb

class ClientsController < ApplicationController 
    def show 
    @client = Client.find(params[:id]) 
    end 

    def new 
    @client = Client.new 
    @client.users.build # Initializes an empty user to be used on new form 
    end 

    def create 
    @client = Client.new(params[:client]) 
    if @client.save 
     flash[:success] = "Welcome!" 
     redirect_to @client 
    else 
     render 'new' 
    end 
    end 
end 

應用程序/控制器/ users_controller.rb

class UsersController < ApplicationController 
    . 
    . 
    . 

    def new 
    @user = User.new 
    end 

    . 
    . 
    . 
end 

應用程序/模型/ user.rb

class User < ActiveRecord::Base 
    belongs_to :client 

    . 
    . 
    . 
end 

應用程序/模型/ client.rb

class Client < ActiveRecord::Base 
    has_many :users, dependent: :destroy 
    . 
    . 
    . 

end 

感謝您的幫助！

Answer 1

在您的user_spec中，您打電話給client.users，但它出現在其他地方，客戶端屬於用戶（單數）。如果是，請嘗試如下：

FactoryGirl.define do 
    factory :client do 
    ... 
    association :user 
    end 
end 

describe User do 
    let(:user) { FactoryGirl(...) } 
    let(:client) { FactoryGirl(:client, :user => user) } 
    subject { user } 
    it { should respond_to(:name) } 
end
