instructions_routing_spec.rb

    DatabaseCleaner.start
  end

  after(:each) do

instructions_controller.rb

    @instruction = Instruction.new

spec_helper.rb

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'

routes.rb

  resources :instructions, :path => "help", :as => "help"
  resources :instructions, :only => [:index,:show]

rake路由输出

instructions#destroy
                      instructions GET        /instructions(.:format)
instructions#index
                      instruction GET      /instructions/:id(.:format)

有跟随错误的；

失败/错误:get(“/指令/新”).should route_to("instructions#new")已识别的选项<{“id”“=>”new“、”action“”=>“show”“>>不匹配<{”action“”=>“new”、“控制器”“=>”指令“}”}>、差异：<{"id"=>"new“、”action“”=>“new}>。<{“操作”“=>”“new”、“控制器”“=>”指令“}”>预期，但<{“id”“=>”new“、”action“”=>“show”、“=>”=>指令“}>。 注： rpsec 2.11.0，rails 3.2.19，ruby1.8.7

它应该像/:控制器/:action/:id，但是我不知道做错了什么，请帮助.好了！

Answer 1

好吧，这里可能有几个问题。首先，要在matcher中使用参数，需要执行如下操作：

  get("/instructions/new/1").should route_to("instructions#new", id: 1)

这假定您已将路由指定为/:instructions/:new/:id。

如果您的路由是/:instructions/:id/:new格式的，那么您自然需要相应地修改匹配器：

  get("/instructions/1/new").should route_to("instructions#new", id: 1)

但是，我觉得您一开始就设置了错误的路由--通常在调用new操作时，在控制器上，您不会为资源提供id (毕竟它还没有创建)。因此，你可能想要考虑改变路线，离开你的对手的原样。

您为rake路由提供的输出看起来不太正确，似乎缺少一些输出，但是您可能应该将路由更改为：

resources :instructions, :only => [:new, :index, :show]
