重新加载不在rspec中工作的对象

Question

我试图用以下代码测试控制器方法:

it "should set an approved_at date and email the campaign's client" do
  @campaign = Campaign.create(valid_attributes)

  post :approve, id: @campaign.id.to_s

  @campaign.reload
  @campaign.approved_at.should_not be(nil)
end

但是,当我运行此测试时,我收到以下错误:

 Failure/Error: @campaign.reload
 ActiveRecord::RecordNotFound:
   Couldn't find Campaign without an ID

当我在rails控制台中运行类似的行时,重新加载工作并且值设置为我需要它.当我在rspec测试中运行代码时,为什么不重新加载？

Answer 1

我通过切换到FactoryGirl解决了这个问题:

  @campaign = FactoryGirl.create(:pending_approval_campaign)
  @campaign.approved_at.should be(nil)

  post :approve, id: @campaign.id.to_s

  @campaign.reload
  @campaign.approved_at.should_not be(nil)

这按预期工作
