Question

当我从浏览器访问我的页面（控制器操作）时，页面渲染正常。当我尝试从控制器规范访问该页面时，它失败了。

使用浏览器记录页面的消息：

Started GET "/listings/2" for ::1 at 2017-12-30 17:10:13 -0500
Processing by Web::ListingsController#show as HTML
  Parameters: {"id"=>"2"}
  Listing Load (0.3ms)  SELECT  "listings".* FROM "listings" WHERE "listings"."id" = $1 LIMIT 1  [["id", 2]]
  User Load (0.2ms)  SELECT  "users".* FROM "users" WHERE "users"."id" = $1  ORDER BY "users"."id" ASC LIMIT 1  [["id", 1]]
  Rendered web/listings/show.html.erb within layouts/web/application (0.8ms)
Completed 200 OK in 12ms (Views: 3.5ms | ActiveRecord: 0.5ms)
source=rack-timeout id=b2c36cc7e27a8a1be766ef1d6f5d571a timeout=10000ms service=16ms state=completed

我的错误来自规范：

  1) Web::ListingsController when logged in GET #show assigns the requested listing as @listing
     Failure/Error: get :show, params: {id: listing.to_param}

     ActionController::UrlGenerationError:
       No route matches {:action=>"show", :controller=>"web/listings", :params=>{:id=>"158"}}

我很确定我在某个地方错过了某种配置设置，但经过几个小时的挖掘后，我没有看到它。有人能指出我可以解决这个问题吗？

相关路线条目：

Rails.application.routes.draw do
  resources :listings, controller: "web/listings"
end

规格/控制器/网络/ listings_controller_spec.rb

RSpec.describe Web::ListingsController, type: :controller do
  describe "GET #show" do
    it "assigns the requested listing as @listing" do
      listing = FactoryBot.create(:listing, user: @user)
      @puts controller.url_for(listing)
      get :show, params: {id: listing.to_param}
      expect(assigns(:listing)).to eq(listing)
    end
  end
end

and the output of that puts statement: http://test.host/listings/158

class Web::ListingsController < ApplicationController
   def show 
      ...
   end

嵌套路由和嵌套控制器不是一回事。假设你确实想要一个像网页/列表＆＃39;尝试：

Rails.application.routes.draw do
  namespace :web do
    resources :listings
  end
end

如果您不想/需要命名路由，请尝试命名帮助程序，例如。 get listing_path(listing)

问题在于规范，特别是如何传递参数。

RSpec.describe Web::ListingsController, type: :controller do
  describe "GET #show" do
    it "assigns the requested listing as @listing" do
      listing = FactoryBot.create(:listing, user: @user)
      get :show, {id: listing.to_param}
      expect(assigns(:listing)).to eq(listing)
    end
  end
end

不要包含params:位。此代码来自脚手架生成器：/
