Question

我一直在使用Rails 3并尝试使用Rails 4.我在这里关注ToDo教程：http://www.codelearn.org/ruby-on-rails-tutorial/introduction-views-layouts-helpers-assets-pipeline

我正在尝试使用Rails＆＃39; link_to＆＃39;删除ToDo项目。辅助方法，并且一直在线查找并且在过去90分钟内无法使用它，所以我决定寻求帮助。

以下是我收到的错误消息：

Routing Error
No route matches [DELETE] "/todos/delete_path"

这是我的耙路线＆＃39;来自终端：

Prefix Verb   URI Pattern             Controller#Action
 todos_index GET    /todos/index(.:format)  todos#index
todos_delete DELETE /todos/delete(.:format) todos#delete

这是＆＃39; link_to＆＃39;来自内部的辅助方法：

index.html.erb

<%= link_to 'Delete last todo', 'delete_path', method: :delete %>

这是我的：

routes.rb

Rails.application.routes.draw do
  get 'todos/index'
  # get 'todos/delete'
  match 'todos/delete' => 'todos#delete', via: :delete

这是我的：

todos_controller.rb

class TodosController < ApplicationController
  def index
    # @todo_array = ['Buy Milk', 'Buy Soap', 'Pay bill', 'Draw Money']
    @todo_items = Todo.all
    render :index
  end

  def delete
    #put delete logic here
    @todo_items = Todo.last
    @todo_items.destroy
  end

end

感谢您抽出宝贵时间来查看我的问题！

Answer 1

这就是编写destroy方法的方法：

def destroy
  @todo = Todo.last
  @todo.destroy
  redirect_to todos_index_path #or wherever you want to redirect user after deleting the tod
end

另外，我只想使用RESTful路线：

Rails.application.routes.draw do
  resources :todos, only: %i(index destroy)
end
