“没有路线匹配”；错误？ [英] "No route matches" error?

问题描述

我是Rspec新手，刚开始是在Rails 3上生成一个新的控制器。它默认会生成一些Rspec测试。我有一个关于如何使它们通过的问题。就目前而言，我在终端中看到该测试

I am new Rspec and just started by generating a new controller on Rails 3. It generates some Rspec tests by default. I have a question about how to make them pass though. As it stands, I see this test in my terminal"

1）BuildingsController GET'show'
应该成功

1) BuildingsController GET 'show' should be successful

 Failure/Error: get 'show'
 No route matches {:controller=>"buildings", :action=>"show"}
 # ./spec/controllers/buildings_controller_spec.rb:17:in `block (3 levels) in <top (required)>'

但是，我不明白为什么会这样，因为我已经创建了这条路线（ resources：buildings ），然后我运行了耙路并确保它在那里。

However, I don't understand why it's coming up because I already have this route created ("resources :buildings"), and I ran rake routes and made sure it's there.

GET /buildings/:id(.:format）{：action => show，：controller => buildings}

building GET /buildings/:id(.:format) {:action=>"show", :controller=>"buildings"}

通过此考试有什么必要？这是测试的方式：

What is necessary to make this pass? Here is the test by the way:

  describe "GET 'show'" do
    it "should be successful" do
      get 'show'
      response.should be_success
    end
  end

推荐答案

您需要传递现有建筑物的ID ： get：show，：id => @ building.id

You need to pass id of existing building: get :show, :id => @building.id

路由对此有所抱怨，因为：id 不是可选的

Routes complain about it because :id isn't optional.
