Ruby on Rails 3:has_one 关联测试 [英] Ruby on Rails 3: has_one association testing

问题描述

我可能把我的联想搞砸了.我有以下模型:User 和 UserProfiles.

I may have my associations messed up. I have the following models: User and UserProfiles.

我的模型:

class User < ActiveRecord::Base
    has_one :user_profile, :dependent => :destroy
    attr_accessible :email
end

class UserProfile < ActiveRecord::Base
    belongs_to :user
end

我的 user_profiles 表中有一个名为user_id"的列.

I have a column named "user_id" in my user_profiles table.

我的工厂是这样设置的:

My factory is setup like so:

Factory.define :user do |user|
  user.email "[e-mail]"
end

Factory.sequence :email do |n|
  "person-#{n}@example.com"
end

Factory.define :user_profile do |user_profile|
  user_profile.address_line_1 "123 Test St"
  user_profile.city "Atlanta"
  user_profile.state "GA"
  user_profile.zip_code "30309"
  user_profile.association :user
end

我的 user_spec 测试设置如下:

My user_spec test is setup like so:

describe "profile" do

    before(:each) do
      @user = User.create(@attr)
      @profile = Factory(:user_profile, :user => @user, :created_at => 1.day.ago)
    end

    it "should have a user profile attribute" do
      @user.should respond_to(:user_profile)
    end

    it "should have the right user profile" do
      @user.user_profile.should == @profile
    end

    it "should destroy associated profile" do
      @user.destroy
      [@profile].each do |user_profile|
        lambda do
          UserProfile.find(user_profile)
        end.should raise_error(ActiveRecord::RecordNotFound)
      end
    end
  end

我的 user_profile_spec 设置如下:

My user_profile_spec is setup like so:

describe UserProfile do

  before(:each) do
    @user = Factory(:user)
    @attr = { :state => "GA" }
  end

  it "should create a new instance with valid attributes" do
      @user.user_profiles.create!(@attr)
  end


  describe "user associations" do
    before(:each) do
      @user_profile = @user.user_profiles.create(@attr)
    end

    it "should have a user attribute" do
      @user_profile.should respond_to(:user)
    end

    it "should have the right associated user" do
      @user_profile.user_id.should == @user.id
      @user_profile.user.should == @user
    end
  end
end

当我运行测试时，我得到# 的未定义方法`user_profiles'".我的测试有什么问题，还是我的关系有问题?

When I run the tests I get "undefined method `user_profiles' for #". How is my test flawed or is my relationship flawed?

谢谢！

推荐答案

您有一个名为 user_profile(单数)的 has_one 关联.您没有名为 user_profiles(复数)的关联.

You have a has_one association called user_profile (singular). You do not have an association called user_profiles (plural).
