当我运行RSpec测试时，ActiveRecord :: RecordNotFound

Question

在视图/页面中，我触发字段更改（无表单提交）的jQuery发布，以更新数据库表中的日期字段。 在我的开发服务器中，这似乎工作得很好，但当我运行此测试时，我得到一个ActiveRecord :: RecordNotFounderror，即使此语句之前/之后的计数返回1，我在FireFox中也可以看到它是查找第一行并填写日期。

在测试日志中，我看到所有数据都在对象实例化之前从订单行中删除，这是导致此错误的原因，但我没有看到其他测试中发生的情况。 这让我发疯，感谢您的帮助！

错误

Failures:

  1) Order Pages - WWhen a need by date is updated should update the line with the correct date
     Failure/Error: Unable to find matching line from backtrace
     ActiveRecord::RecordNotFound:
       Couldn't find OrderLine with id=1

RSPEC

require 'spec_helper'

describe "Order Pages - " do

  subject { page }

  before do
    create_order_and_sign_in_user 
  end

  def visit_a_order
    @order = @user.order.first
    visit order_lines_path(@order)
  end

  describe "When a need by date is updated" do

    it "should update the line with the correct date", js: true do
      visit_a_order  
         puts "Order lines count 1 - #{@order.lines.count}" // is 1 
      fill_in "needby_date", :with => "09/18/2014"
        puts "Order lines count 2 - #{@order.lines.count}" // is 1         
    end

  end  

end 

RSPEC帮手

module OrderHelper

  def create_order_and_sign_in_user

     @user = create(:user)
     @order = create(:order, user: @user)
     @order_line = @order.order_line.create(description: "Order 1, Line 1")

     sign_in @user

  end

end

include ApplicationHelper

  def sign_in(user)
   visit new_user_session_path
   fill_in "Email", with: user.email
   fill_in "Password", with: user.password
   click_button "Sign in"
  end

  def fixture_file_path(file_name)
   File.join(fixture_path, file_name)
  end

控制器

  def update_needby_date

    puts "Got to 1 - #{params[:order_line_id]}"
    @order_line = OrderLine.find(params[:order_line_id]) //Fails here with an ActiveRecord::RecordNotFound error
    puts "Got to 2 - #{params[:order_line_id]}"
    @order_line.needby_date = Date::strptime(params[:needby_date], "%m/%d/%Y")
    @order_line.save!
    respond_to do |format|
      format.js   { render :nothing => true }
    end

  end

我想所需要的只是从现场跳出来。 因此，我最终在同一页面上填写了另一个字段，这使该测试通过了。

  describe "When a need by date is updated" do

     it "should update the line with the correct date", js: true do
      visit_a_order  
      fill_in "needby_date", :with => "09/18/2014"
      fill_in "line_description", :with => "Sample line!"
     end

  end
