集成测试在 rails 4 中获得 ActionController::UrlGenerationError

Integration test get ActionController::UrlGenerationError in rails 4

我是 rails 的新手:( 尝试编写一些测试来编辑用户的预订信息,这是我得到的,我检查了 stackover 上的其他帖子,似乎无关任何线索?对你的帮助表示感谢 !

ActionController::UrlGenerationError: 

No route matches {:action=>"edit", :controller=>"bookings", :id=>nil} missing required keys: [:id]

测试代码:

require 'test_helper'
    class BookingEditTest < ActionDispatch::IntegrationTest
        def setup
            @user = users(:michael)
        end

        test "unsucessful edit" do 
          log_in_as(@user)
          get edit_booking_path(@booking)
          assert_template 'bookings/edit'
          patch booking_path(@booking), booking: {date_of_tour: "2017-05-06", hotel_name: " ", hotel_address:"dadsada das",phone_number:12345678901 , number_of_pax:34 , pick_up_time: "9:00"}
          assert_template 'bookings/edit'
        end
    end

路线:resources :bookings, only: [:show,:new, :create, :edit, :update,:destroy]

预订模型:belongs_to:用户

用户模型:has_many :bookings, dependent: :destroy

booking_controller.rb

class BookingsController < ApplicationController
  before_action :logged_in_user, only: [:show, :edit,:create, :destroy]

  def show
    @booking = Booking.find(params[:id])
  end

  def new
    @booking = Booking.new
  end

  def create
    @booking = current_user.bookings.build(booking_params) 
    if @booking.save
      flash[:success] = "You have submited the information successfully!"
      redirect_to root_url
    else
      render 'new'
    end
  end

  def edit
    @booking = Booking.find(params[:id])
  end

  def update
    @booking = current_user.bookings.find_by(params[:id])
    if @booking.update_attributes(booking_params)
      flash[:success] = "information updated"
      redirect_to @booking
    else
      render 'edit'
    end
  end

  def destroy
  end

  private

  def booking_params
    params.require(:booking).permit(:date_of_tour,:hotel_address,:hotel_name,:phone_number,:number_of_pax,:pick_up_time)
  end
end

你说的是

edit_booking_path(@booking)

但@booking 尚未定义,路径助手无法为不存在的预订生成 url。

您必须先创建一个 Booking 实例,然后才能尝试使用它。
