Rails布线问题

Question

I am very new to Ruby on Rails and I have been working with a project while learning but I have run into an issue. I am trying to set up a link from a view under a "task" controller to a view for new timetracks. I am attempting to link on the view like so:

<%= link_to "New Timetrack", new_project_list_task_timetrack_path(@project, @list, @task) %>

And I am getting this error:

No route matches {:action=>"new", :controller=>"timetracks", :project_id=>nil, :list_id=># < List id: 1, name: "Test", description: "Test", created_at: "2013-12-18 21:00:39", updated_at: "2013-12-18 21:00:50", project_id: 1, default: nil>, :task_id=>#>Task id: 1, description: "First Task", completed: false, list_id: 1, created_at: "2013-12-18 21:00:57", updated_at: "2013-12-18 21:00:57", default: nil>}

I made sure that there was an action "new" in the timetracks controller. I am creating the link the way above because of how I saw Rails scaffold the relation between projects and lists which was like so:

<%= link_to "Create To-Do", new_project_list_path(@project) %>

So I'm stumped and would like some help. Any information is appreciated!

Answer 1

尝试使用new_project_timetrack_path如果没有帮助，请查看bash命令rake routes的输出，并找到所需的路由。

Answer 2

in your config/routes.rb must be rows like these:

resources :projects do    
  resources :lists do    
    resources :tasks do    
      resources :timetracks    
    end
  end
end

and then rake compile path like

host:3000/projects/<project_id>/lists/<list_id>/tasks/<task_id>/timetracks/new

I hope this can help you.
