路径规格似乎并不匹配生成的方法

Question

当我刷新页面我得到这个错误信息：

ActionController::RoutingError (No route matches {:action=>"value", :controller=>"round"}): 
    app/views/surveys/survey.html.erb:28:in `block in _app_views_surveys_survey_html_erb___3955880096442191391_70175035205180' 
    app/views/surveys/survey.html.erb:22:in `_app_views_surveys_survey_html_erb___3955880096442191391_70175035205180' 
    app/controllers/surveys_controller.rb:16:in `block (2 levels) in survey' 
    app/controllers/surveys_controller.rb:14:in `survey'  
    Rendered /Users/pitosalas/.rvm/gems/ruby-1.9.3-p194@repeatsurvey/gems/actionpack-3.2.8/lib/action_dispatch/middleware/templates/rescues/routing_error.erb within rescues/layout (0.5ms) 

我感到很困惑这个。为什么引用program_participant_round_value_path引起该路线丢失？

这是我的路线文件：

root to: 'programs#index' 
    resources :programs do 
    resources :participants do 
     get 'survey' => 'surveys#survey' 
    end 
    resources :questions 
    resources :rounds 
    member do 
     get 'report' => 'reports#report' 
    end 
    end 
    resources :program do 
    resources :participant do 
     resources :round do 
     put :value 
     end 
    end 
    end 

而这里的相关耙路线：

program_participant_round_value PUT /program/:program_id/participant/:participant_id/round/:round_id/value(.:format) round#value 

我有一个控制器动作回合＃值。

这里的视图的相关部分：

<%= content_tag :table do %> 
    <%= content_tag :thead do %> 
    <% 5.times do |q| %> 
     <%= content_tag :th, "1" %> 
    <% end %> 
    <% end %> 
    <% form_tag program_participant_round_value_path do %> 
    <%= content_tag :tbody do %> 
     <%= render partial: 'surveys/value', collection: @values %> 
    <% end %> 
    <%= submit_tag "Save" %> 
    <% end %> 
<% end %> 

谢谢！

Answer 1

你program_participant_round_value航线期待几个参数：

• :program_id
• :participant_id
• :round_id

您需要为那些当你调用program_participant_round_value_path辅助参数提供值：

program_participant_round_value_path(program_id: @program, participant_id: @participant, round_id: @round) 

当然，根据您在控制器中定义它们的方式，变量名称等可能会略有不同。
