Question

When I refresh the page I get this error message:

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'

I am very confused by this. Why is the reference to program_participant_round_value_path causing that route to be missing?

Here’s my routes file:

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

And here’s the relevant rake routes line:

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

I have a controller action round#value.

Here’s the relevant part of the view:

<%= 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 %>

Thanks!

Your program_participant_round_value route is expecting several parameters:

• :program_id
• :participant_id
• :round_id

You need to provide values for those parameters when you call the program_participant_round_value_path helper:

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

Of course, variable names and such may be slightly different depending on how you are defining them in the controller.
