Question

我无法弄清楚为什么我的测试失败了。我认为这与我使用的删除方法有关。无论出于何种原因，我都无法获得删除操作的正确链接。该网站的代码有效，但我似乎无法让Rspec映射到该网站发生的事情。有什么想法吗？

查看：

    <li>
      <%= link_to hunt.name, hunt %>
      <% if current_user && current_user.admin? %>
        | <%= link_to "edit", edit_hunt_path(hunt) %>
        | <%= link_to "delete", hunt, :method => :delete, :confirm => "You sure?",
                                    :title => "Delete #{hunt.name}" %>    
      <% end %>
    </li>

Rspec测试：

require 'spec_helper'

describe HuntsController do
  render_views 

  describe "GET 'index'" do
  ...
    describe "for users who are admins" do
       before(:each) do
          admin = FactoryGirl.create(:user, :email => "admin@example.com", :admin => true)
          test_sign_in(admin)
        end
        ...
        it "should show delete link" do
          get 'index'
          Hunt.paginate(:page => 1).each do |hunt|
            response.should have_selector('a', :href => hunt_path(@hunt)   , :content => 'delete')
          end
        end              
    end  
   end

Rspec输出：

   1) HuntsController GET 'index' for users who are admins should show delete link
     Failure/Error: response.should have_selector('a', :href => hunt_path(@hunt)   , :content => 'delete')
     ActionController::RoutingError:
       No route matches {:action=>"show", :controller=>"hunts"}
     # ./spec/controllers/hunts_controller_spec.rb:64:in `block (5 levels) in <top (required)>'
     # ./spec/controllers/hunts_controller_spec.rb:63:in `block (4 levels) in <top (required)>'

这是运行＆＃34; rake路线的输出＆＃34;：

不确定为什么会发生这种情况。但是日志指出视图尝试呈现指向hunts#show

的链接

http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to

有示例，例如视图中的第一个链接：

<%= link_to hunt.name, hunt %>

我假设link_to无法获取hunt的id并且因为RoutingError而逃脱。 hunt可能是零吗？

无论哪种方式，Ben说用以下代替前一行：

<%= link_to hunt.name, hunt_path(hunt) %>

解决了这个问题。

什么是适当的Rspec语法
