Ruby on rails Rspec设置问题

我的rspec设置有问题，但我不确定是什么，所有的规范都是按照正常的方式编写的，但没有任何东西运行正常

比如说,

13) Event associations should have many :jobs
 Failure/Error: it { should have_many :jobs }
 NoMethodError:
   undefined method `has_many?' for #<Event:0x007ffdb0140978>
 # ./spec/models/event_spec.rb:14:in `block (3 levels) in <top (required)>'


  8) Event validations 
 Failure/Error: it { should validate_presence_of :start_date }
 NoMethodError:
   undefined method `validate_presence_of' for #<RSpec::ExampleGroups::Event_2::Validations:0x007ffdb02a1268>
 # ./spec/models/event_spec.rb:7:in `block (3 levels) in <top (required)>'

13）事件关联应该有多个：作业
失败/错误：它{应该有_许多：作业}
命名错误：
未定义的方法'has_many'#
#./spec/models/event_spec.rb:14:in'block（3层）in'
8） 事件验证
失败/错误：它{应该验证是否存在：开始日期}
命名错误：
未定义的方法“验证是否存在”#
#./spec/models/event_spec.rb:7:in'block（3层）in'

我正在做TDD，所以在它启动和运行之前无法真正开始，请提供帮助

编辑

Event.rb

class Event < ActiveRecord::Base
 validates_presence_of :start_date, :end_date, :description, :title

 has_many :jobs
 has_many :applications, through: :jobs
 has_many :users, through: :applications
 has_many :companies, through: :jobs
end

require 'spec_helper'

describe Event do
  context "validations" do
  it { should validate_presence_of :title }
  it { should validate_presence_of :description }
  it { should validate_presence_of :start_date }
  it { should validate_presence_of :end_date }
  end

context "associations" do
 it { should have_many :companies }

 it { should have_many :jobs }
 it { should have_many(:applications).through(:jobs) }
 it { should have_many(:users).through(:applications) }
end

context "custom methods" do

end
end

class事件

您需要在

测试

组中添加

shoulda matchers

group :test do
  gem 'shoulda-matchers'
end

如果您显示导致错误的代码，这将更有帮助。i、 e.事件规格。rb@Dty补充！看一看，谢谢你在用Shoulda吗？如果是，请将此gem包含在所需匹配器中：
