rspecvalidation失败

我有一个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  "requestor_id", :class_name => "Meeting" has_many :received_meetings, :foreign_key => "requestee_id", :class_name => "Meeting" 

我无法弄清楚如何防止我的meeting_spec.rbvalidation失败。 出于某种原因，我的sent_meetings或requested_meetings（类会议）没有链接到他们各自的请求者或被请求者（类用户）（最后两个代码块，“当requestor_id不存在时”，“当requestee_id不存在时”）。

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 

这是我得到的rspec错误：

 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 ' 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 ' 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 

非常感谢有关如何在用户（请求者，被请求者）和会议（sent_meeting，requested_meeting）之间建立关联的任何输入。

谢谢！

在你的模型中，你要求两个id都存在

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

所以如果你在规范中没有其中一个

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

它们无效，无效，因为您声明它们在这种情况下无效。
