rspec的失敗驗證

Question

我有一個meeting.rb和user.rb模型

meeting.rb

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

    validates :requestor_id, presence: true 
    validates :requestee_id, presence: true 

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

end 

user.rb

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

    has_many :sent_meetings, :foreign_key => "requestor_id", :class_name => "Meeting" 
    has_many :received_meetings, :foreign_key => "requestee_id", :class_name => "Meeting" 

我無法弄清楚如何防止我的meeting_spec .rb驗證失敗。出於某種原因，我的sent_meetings或requested_meetings（類會議）沒有鏈接到它們各自的請求者或請求者（類用戶）（最後兩個代碼塊，「當requestor_id不存在時」，「當requestee_id不存在時」）。

meeting_spec.rb

require 'spec_helper' 

describe Meeting do 

    let(:requestee) { FactoryGirl.create(:user) } 
    let(:requestor) { FactoryGirl.create(:user) } 

    before { @received_meeting = requestee.received_meetings.build(intro: "Lorem ipsum") } 
    before { @sent_meeting = requestor.sent_meetings.build(intro: "Lorem ipsum") } 

    describe "sent meetings" do 
    subject { @sent_meeting } 
     it { should respond_to(:intro) } 
     it { should respond_to(:requestor_id) } 
     it { should respond_to(:requestor) } 
     its(:requestor) { should == requestor } 
     it { should be_valid } 
    end 

    describe "received meetings" do 
    subject { @received_meeting } 
     it { should respond_to(:intro) } 
     it { should respond_to(:requestee_id) } 
     it { should respond_to(:requestee) } 
     its(:requestee) { should == requestee } 
     it { should be_valid } 
    end 

    describe "accessible attributes" do 
    it "should not allow access to requestor_id" do 
     expect do 
     Meeting.new(requestor_id: requestor.id) 
     end.should raise_error(ActiveModel::MassAssignmentSecurity::Error) 
    end 

    it "should not allow access to requestee_id" do 
     expect do 
     Meeting.new(requestee_id: requestee.id) 
     end.should raise_error(ActiveModel::MassAssignmentSecurity::Error) 
    end 
    end 

    describe "when requestor_id is not present" do 
    before { @sent_meeting.requestor_id = nil } 
    it { should be_valid } 
    end 

    describe "when requestee_id is not present" do 
    before { @received_meeting.requestee_id = nil } 
    it { should be_valid } 
    end 
end 

這裏是RSpec的錯誤，我得到：

Failures: 

    1) Meeting sent meetings 
    Failure/Error: it { should be_valid } 
     expected valid? to return true, got false 
    # ./spec/models/meeting_spec.rb:17:in `block (3 levels) in <top (required)>' 

    2) Meeting received meetings 
    Failure/Error: it { should be_valid } 
     expected valid? to return true, got false 
    # ./spec/models/meeting_spec.rb:26:in `block (3 levels) in <top (required)>' 

Finished in 0.77435 seconds 
42 examples, 2 failures 

Failed examples: 

rspec ./spec/models/meeting_spec.rb:17 # Meeting sent meetings 
rspec ./spec/models/meeting_spec.rb:26 # Meeting sent meetings 

會很感激，就如何使會議和用戶之間的關聯（請求，被請求方）任何輸入（ sent_meeting，requested_meeting）。

謝謝！

在模型中

你的要求都IDS的存在與

validates :requestor_id, presence: true 
    validates :requestee_id, presence: true 

所以如果你NIL其中一個作爲您的規範

describe "when requestor_id is not present" do 
    before { @sent_meeting.requestor_id = nil } 
    it { should be_valid } 
    end 

它們是無效的，無效的，因爲你在這種情況下宣稱他們不是有效的。
