Ruby on rails 3 Rails-没有路由匹配{：action=>；new"；，：controller=>；comments"；}

尝试了所有方法，但似乎找不到问题所在

本地主机上的错误：3000

No route matches {:action=>"new", :controller=>"comments"}

服务器错误

Rendered tasks/show.html.erb within layouts/application (134.7ms)
Completed 500 Internal Server Error in 187ms

ActionView::Template::Error (No route matches {:action=>"new", :controller=>"comments"}):
    66: 
    67: <br />
    68: 
    69: <%= link_to 'New Comment', new_task_comment_path %>

  app/controllers/tasks_controller.rb:18:in `show'

以及我的

$rake routes

$ rake routes
    task_comments GET    /tasks/:task_id/comments(.:format)          {:action=>"index", :controller=>"comments"}
                  POST   /tasks/:task_id/comments(.:format)          {:action=>"create", :controller=>"comments"}
 new_task_comment GET    /tasks/:task_id/comments/new(.:format)      {:action=>"new", :controller=>"comments"}
edit_task_comment GET    /tasks/:task_id/comments/:id/edit(.:format) {:action=>"edit", :controller=>"comments"}
     task_comment GET    /tasks/:task_id/comments/:id(.:format)      {:action=>"show", :controller=>"comments"}
                  PUT    /tasks/:task_id/comments/:id(.:format)      {:action=>"update", :controller=>"comments"}
                  DELETE /tasks/:task_id/comments/:id(.:format)      {:action=>"destroy", :controller=>"comments"}

我在这里遗漏了什么？

您没有向其传递

任务id

：

new_task_comment_path(@task.id)

一旦那个讨厌的计时器用完了，我就去

new_task_comment_path(@task.id)
