Question

我在rails应用程序中添加了一条额外的路由到这样的嵌套资源。

 resources :questions do 
    resources :answers do 

       match "/bestanswer", :to => "answers#bestanswer", :via => :post

      end
  end

运行'rake routes'会显示以下路径

question_answer_bestanswer POST   /questions/:question_id/answers/:answer_id/bestanswer(.:format) answers#bestanswer

我尝试使用表单中的路径（每个答案重复多次），如此

<%= form_tag question_answer_bestanswer_path, method: :post do%>
   <%= hidden_field_tag :answer_id, answer.id %>
   <%= hidden_field_tag :question_id, answer.question.id %>
   <%= submit_tag "Accept this answer as the best answer", :class => 'btn ' %>
<% end %>

但是，当我转到显示此表单的页面时，我收到此错误

No route matches {:controller=>"answers", :action=>"bestanswer"}

你能解释一下我做错了吗？

Answer 1

您缺少路线参数，您的表格应为：

<%= form_tag question_answer_bestanswer_path( answer.question, answer ), method: :post do%>
   <%= submit_tag "Accept this answer as the best answer", :class => 'btn ' %>
<% end %>

并且hidden_field_tag不是必需的。

“耙路线”中没有显示路线的路线
