【问题描述】：
我正在尝试编写一个 rspec 测试；
- 访问商店页面
- 在“国家/地区”选择框中选择一个值
- 并测试该值是否存在（最初在“国家/地区”框中，但我还将在第二次测试中测试依赖于国家/地区的城市）

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
失败
失败：
1) 索引 失败/错误：访问 store_path 无方法错误： nil:NilClass 的未定义方法“id”
rails 控制台 [app.store_path] 验证 store_path 是 '/store'
选择框根据本博客posting中的说明动态填充
任何帮助表示赞赏，在此先感谢
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'
它的一个索引页面（store_path）有一个国家选择框。
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
