ActionController :: UrlGenerationError:即使我将ID传递给测试,也没有路线匹配且缺少ID

标签: ruby-on-rails actiondispatch

我还是不熟悉Rails,并试图为我的一个控制器编写一些基本测试。

为了使这个问题简短,让我们看一下我的两个测试。

  • should show captable失败
  • should get index asserts成功

从下面的错误中,我可以看到missing required keys: [:id]的问题,但是我正在传递ID-因此我无法弄清楚问题是什么。

感谢任何帮助:)

测试文件(仅包含与此问题相关的测试)

require 'test_helper'

class CaptablesControllerTest < ActionDispatch::IntegrationTest
  include Devise::Test::IntegrationHelpers

  setup do
    @captable = captables(:one)
  end

  setup do
    @company = companies(:one) 
  end

  setup do 
    @user = users(:one) 
  end

  test "should show captable" do
    sign_in @user
    get company_captable_url(@captable), id: @captable.id
    assert_response :success
  end

  test "should get index" do
    sign_in @user
    get company_captables_url(@company)
    assert_response :success
  end
....

控制器(仅包括相关方法)

class CaptablesController < ApplicationController
  before_action :set_company
  before_action :set_captable, only: [:show, :edit, :update, :destroy]

  def index
    @captables = @company.captables
  end

  def show
    @captable = Captable.find(params[:id])
  end
.....

one:
  id: 1
  version: 1
  name: MyText
  company_id: 1

这是尝试运行测试时的错误

Error:
    CaptablesControllerTest#test_should_show_captable:

ActionController :: UrlGenerationError:没有路由匹配   {:action =>“ show”,:company_id =>功能编号:1,版本:1,名称:   “ MyText”,company_id:1,created_at:“ 2018-10-17 18:34:14”,   Updated_at:“ 2018-10-17 18:34:14”,total_stocks_in_company:无,   :controller =>“ captables”},缺少必需的键:[:id]

您认为您的路径助手company_captable_url是使用嵌套资源构建的。因此,它期望两个动态段的值,即:company_id:id。因此,@company应该与@captable一起传递。您需要将其更改为以下

test "should show captable" do
  sign_in @user
  get company_captable_url(@company, @captable)
  assert_response :success
end
