当我刷新页面时，我收到此错误消息：

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/controllers/surveys_controller.rb:16:in `block (2 levels) in survey'

我对此感到非常困惑。为什么对 program_participant_round_value_path 的引用导致该路由丢失？

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

这是相关的 rake routes 行：

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 round#value。

这是视图的相关部分：

<%= 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！

您的program_participant_round_value路线需要几个参数：

  • :program_id
  • :participant_id
  • :round_id

当您调用帮助程序时，您需要为这些参数提供值program_participant_round_value_path：

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

当然，变量名称等可能会略有不同，具体取决于您在控制器中定义它们的方式。
