rspec水豚选择器滑轨4

Question

I am trying to write an rspec test that will; 我正在尝试编写一个将要的rspec测试；

visit the store page 访问商店页面
select a value in the Countries select box 在国家选择框中选择一个值
and test that the value exists (initially in the Countries box but I would also be testing for cities which is dependent on Country in the second test) 并测试该值是否存在（最初在“国家/地区”框中，但我还将在第二项测试中测试依赖于国家/地区的城市）

My test 我的测试

require 'spec_helper'

describe "index" do

  subject { page }

  before do

    visit store_path

    select "United Kingdom", :from => "catalogue[country_id]"

  end

  it { should have_select('country_id', :selected => 'United Kingdom') }

end

The failures 失败

Failures: 失败：

1) index Failure/Error: visit store_path NoMethodError: undefined method `id' for nil:NilClass 1）索引失败/错误：访问store_path NoMethodError：nil：NilClass的未定义方法'id'

The rails console [app.store_path] verifies that store_path is '/store' Rails控制台[app.store_path]验证store_path为'/ store'

The select boxes are dynamically populated according to the directions in this blog posting 根据此博客文章中的说明动态填充选择框

Any help is appreciated, thanks in advance 任何帮助表示赞赏，在此先感谢

There are the routes 有路线

  match '/store', to: 'store#index', as: :store, via: 'get'

  get 'store/show'

  match 'store/update_cities', to: 'store#update_cities',  as: :update_cities, via: 'get'

  match 'store/update_currencies', to: 'store#update_currencies',  as: :update_currencies, via: 'get'

Its one index page (store_path) which has a countries select box. 它的一个索引页面（store_path）带有一个国家/地区选择框。

This is the store controller 这是商店控制器

  def index

    @countries = Country.all

    @cities = City.where("country_id = ?", Country.first.id)

    @currencies = Currency.where("country_id = ?", Country.first.id)

    @locations = Location.where("city_id = ?", Location.first.id)

    @products = Product.where("Location_id = ?", Product.first.id)

    @plugs = Plug.where("Location_id = ?", Plug.first.id)

  end

  def show
  end

  def update_cities

    @cities = City.where("country_id = ?", params[:country_id])

    respond_to do |format|

      format.js

    end
  end

Answer 1

Are you trying to visit a specific store, or listing all the stores ? 您是要访问特定商店还是列出所有商店？

in your case you are trying to visit a specific store which you need to pass a parameter for it in this case the store id 在您的情况下，您尝试访问的是特定商店，您需要为此传递一个参数，在这种情况下，商店ID

To know the exact path write in the console: 要知道确切的路径，请在控制台中编写：

rake routes

you will find each path to its url, if you want to list all the stores you need to write: 如果要列出需要编写的所有商店，则会找到其URL的每个路径：

stores_path

instead of: 代替：

store_path

store_path is /store/:id store_path是/ store /：id
