在我的 rake 路线中，我得到：

project_todos GET    /project_todos(.:format)                   project_todos#index
                            POST   /project_todos(.:format)                   project_todos#create
           new_project_todo GET    /project_todos/new(.:format)               project_todos#new
          edit_project_todo GET    /project_todos/:id/edit(.:format)          project_todos#edit
               project_todo GET    /project_todos/:id(.:format)               project_todos#show
                            PUT    /project_todos/:id(.:format)               project_todos#update
                            DELETE /project_todos/:id(.:format)               project_todos#destroy
project_todos_toggle_status POST   /project_todos/toggle_status(.:format)     project_todos#toggle_status

从：

resources :project_todos

  post "project_todos/toggle_status"

我的观点中有一条线，如下所示：

<%= link_to 'Toggle Project', project_todos_toggle_status_path(id: todo.id), method: "post" %>

这会产生一个如下所示的链接：

http://localhost:3000/project_todos/toggle_status?id=1

并导致以下错误： 在此处输入图像描述

这很奇怪，因为它进入了 show 操作，我不明白它为什么或如何设置 id = toggle_status.

关于如何完成这项工作的任何想法？我过去使用 static_pages 控制器做过非常相似的事情，这会有什么不同吗？

    <%= todo.id%>
    <%= link_to 'Toggle Project', toggle_status_project_todo_path(todo), method: "post" %>

我相信您正在尝试为单个资源 ProjectTodo “切换状态”，对吗？在 Rails 3 中描述这条路线的更常见的方式如下：

resources :project_todos do
  member do
    post :toggle_status
  end
end

这会在您的路线文件中产生确定性顺序：

toggle_status_project_todo POST   /project_todos/:id/toggle_status(.:format) project_todos#toggle_status
             project_todos GET    /project_todos(.:format)                   project_todos#index
                           POST   /project_todos(.:format)                   project_todos#create
          new_project_todo GET    /project_todos/new(.:format)               project_todos#new
         edit_project_todo GET    /project_todos/:id/edit(.:format)          project_todos#edit
              project_todo GET    /project_todos/:id(.:format)               project_todos#show
                           PUT    /project_todos/:id(.:format)               project_todos#update
                           DELETE /project_todos/:id(.:format)               project_todos#destroy

允许您在视图中编写：

<%= link_to 'Toggle Project', toggle_status_project_todo_path(@todo), method: "post" %>

这将发布到“http://localhost:3000/project_todos/1/toggle_status”

Try moving your project_todos line above the resources: project_todos line in your routes.rb

Then the custom route will be found before the id version.
