rspec的验证失败：“不能为空”

Question

我无法解决以下RSpec的验证错误：

Failures: 

    1) User treating associations should have the right treatings in the right order 
    Failure/Error: FactoryGirl.create(:treating, requestor: @user, created_at: 1.day.ago) 
    ActiveRecord::RecordInvalid: 
     Validation failed: Requestee can't be blank 
    # ./spec/models/user_spec.rb:143:in `block (3 levels) in <top (required)>' 

我负责的两个型号，用户和处理（认为它作为一个会议）：

user.rb

class User < ActiveRecord::Base 
    attr_accessible :name, :email, :password, :password_confirmation 
    has_secure_password 

    has_many :sent_treatings, :foreign_key => "requestor_id", :class_name => "Treating", dependent: :destroy 
    has_many :received_treatings, :foreign_key => "requestee_id", :class_name => "Treating", dependent: :destroy 

end 

treating.rb

class Treating < ActiveRecord::Base 
    attr_accessible :intro, :proposed_date, :proposed_location 

    validates :intro, presence: true, length: { maximum: 190 } 
    validates :requestor_id, presence: true 
    validates :requestee_id, presence: true 

    belongs_to :requestor, class_name: "User" 
    belongs_to :requestee, class_name: "User" 

    default_scope order: 'treatings.created_at DESC' 

end 

最后，从我的user_spec是给我这个错误的部分：我不知道

describe "treating associations" do 
     before { @user.save } 
     let!(:older_treating) do 
      FactoryGirl.create(:treating, requestor: @user, created_at: 1.day.ago) 
      FactoryGirl.create(:treating, requestee: @user, created_at: 1.day.ago) 

     9end 
     let!(:newer_treating) do 
      FactoryGirl.create(:treating, requestor: @user, created_at: 1.hour.ago) 
      FactoryGirl.create(:treating, requestee: @user, created_at: 1.hour.ago) 
     end 

     it "should have the right treatings in the right order" do 
      @sent_treating = requestor.sent_treatings.build(intro: "Lorem ipsum") 
      @sent_treating.requestee = requestee 

      @received_treating = requestee.received_treatings.build(intro: "Lorem ipsum") 
     @received_treating.requestor = requestor 

      requestor.sent_treatings.should == [newer_treating, older_treating] 
      requestee.received_treatings.should == [newer_treating, older_treating] 
     end 

为什么“被请求方”将是空白这里可以使用一些帮助。谢谢。

编辑：工厂在下面，谢谢！

（我已经尝试添加“用户”，“请求”，并在下方的“前奏”“被请求方”：处理厂，但仍然没有成功）。当我在工厂文件中添加“用户”（以下“前奏‘Lorem存有’），我收到以下错误：

1) User treating associations should have the right treatings in the right order 
    Failure/Error: FactoryGirl.create(:treating, requestor: @user, created_at: 1.day.ago) 
    NoMethodError: 
     undefined method `user=' for #<Treating:0x00000104fa0668> 
    # ./spec/models/user_spec.rb:143:in `block (3 levels) in <top (required)>' 

当我添加‘请求者’和‘受邀’到工厂，而不是用户（而除了使用），我收到以下错误：

Failures: 

    1) User treating associations should have the right treatings in the right order 
    Failure/Error: FactoryGirl.create(:treating, requestor: @user, created_at: 1.day.ago) 
    ArgumentError: 
     Trait not registered: requestee 

Answer 1

的问题是，你的处理厂没有定义请求者和受邀人，另外，你需要告诉FactoryGirl该请求者和受邀人是别名为用户

factory :user, :aliases => [:requestor, :requestee] do 
    sequence(:name) { |n| "Person #{n}" } 
    sequence(:email) { |n| "person_#{n}@example.com"} 
    password "foobar" 
    password_confirmation "foobar" 

    factory :admin do 
     admin true 
    end 
end 

factory :treating do 
    intro "Lorem ipsum" 
    requestor 
    requestee 
end 

Answer 2

这是修复。

factories.rb需要在所提到的别名：用户性状线

FactoryGirl.define do 

    factory :user, aliases: [:requestor, :requestee] do 
    sequence(:name) { |n| "Person #{n}" } 
    sequence(:email) { |n| "person_#{n}@example.com"} 
    password "foobar" 
    password_confirmation "foobar" 

    factory :admin do 
     admin true 
    end 
    end 

    factory :treating do 
    intro "Lorem ipsum" 
    requestor 
    requestee 
    end 

end 

最后，“治疗协会”测试需要有旧/新的接收/发送细分为treatings（4种变体）：

describe "treating associations" do 
    before { @user.save } 
    let!(:older_sent_treating) do 
    FactoryGirl.create(:treating, requestor: @user, created_at: 1.day.ago) 
    end 
    let!(:older_received_treating) do 
    FactoryGirl.create(:treating, requestee: @user, created_at: 1.day.ago) 
    end 
    let!(:newer_sent_treating) do 
    FactoryGirl.create(:treating, requestor: @user, created_at: 1.hour.ago) 
    end 
    let!(:newer_received_treating) do 
    FactoryGirl.create(:treating, requestee: @user, created_at: 1.hour.ago) 
    end  

    it "should have the right treatings in the right order" do 
    @user.sent_treatings.should == [newer_sent_treating, older_sent_treating] 
    @user.received_treatings.should == [newer_received_treating, older_received_treating] 
    end 
end 

然后测试应该通过。谢谢！
