訪問商店頁面
選擇在各國家的價值選擇框
，並測試值存在（最初在國家框，但我也將被測試的城市是依賴於國家在第二次測試）

我的測試

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

的故障

失敗：

1）索引故障/錯誤：訪問store_path NoMethodError：未定義的方法`ID」的零：NilClass

軌道控制檯[ app.store_path]驗證store_path是'/ store'

選擇框是動態的根據此博客的方向posting

任何幫助表示讚賞盟友填充，在此先感謝

有路由

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'

它的一個索引頁（store_path），其中有一個國家選擇框。

這是存儲控制器

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

你試圖訪問一個特定的商店，或者列出所有的商店？

你的情況，您嘗試訪問，你需要在這種情況下傳遞參數爲它的商店ID

要知道在控制檯的確切路徑寫一個特定的商店：

rake routes

，你會發現每個路徑的網址，如果你想列出你需要寫的所有商店：代替

stores_path

：

store_path

store_path是/存儲/：ID

我已經加入上述路線和控制器，該「/存儲」路徑路由到store_index.html.erb，這一個頁面有3個選擇框，第一個國家，然後是城市，貨幣。它是我希望測試的選擇框中的值。 – Conor 2014-12-04 20:46:56

國家模式是否有任何條目？可能在種子什麼的？因爲如果沒有，這意味着國家模式中沒有條目。在這種情況下，您正在嘗試查找無對象的ID如同您在索引操作中所說的：Country.first.id，要自己測試它，請嘗試在索引操作中使用調試器 – 2014-12-06 21:43:36

您可以定義種子中的國家或嘗試爲其創建工廠 – 2014-12-06 21:46:58
