我已经关注the tutorial up to 5.13，除博客的两个方面外，一切正常：
我的问题涉及删除链接的无功能
index.html.erb
<h1>My Notes</h1>
<%= link_to 'New Note', new_article_path %>
<table>
<tr>
<th>Note Entry Title</th>
<th>Preview</th>
<th colspan="3"></th>
</tr>
<% @articles.each do |article| %>
<tr>
<td><%= article.title %></td>
<td><%= article.text %></td>
<td><%= link_to 'Show', article_path(article) %></td>
<td><%= link_to 'Edit', edit_article_path(article) %></td>
<td><%= link_to 'Destroy', article_path(article),
method: :delete,
data: { confirm: 'Are you sure?' } %></td> #<<< This is the delete code
</tr>
<% end %>
</table>
articles_controller.rb
class ArticlesController < ApplicationController
def index
@articles = Article.all
end
def show
@article = Article.find(params[:id])
end
def new
@article = Article.new
end
def edit
@article = Article.find(params[:id])
end
def create
#render plain: params[:article].inspect
#@article = Article.new(params.require(:article).permit(:title, :text))
@article = Article.new(article_params)
if @article.save
redirect_to @article
else
render 'new'
end
end
def update
@article = Article.find(params[:id])
if @article.update(article_params)
redirect_to @article
else
render 'edit'
end
end
def destroy #<<< This is the destroy method
@article = Article.find(params[:id])
@article.destroy
redirect_to articles_path
end
private
def article_params
params.require(:article).permit(:title, :text)
end
end
我想我根本不确定如何解决这个问题，因为我已经逐字逐句地阅读了教程，并花了半个星期的时间试图解决这个问题，只是被其他帖子引导到了兔子洞。要么不属于这个问题，要么没有充分的修复。也许我错过了一个错字，但我已经多次梳理过代码了（注意我是一个Ruby初学者，所以这个东西对我来说很新）。
下面是我每次点击页面上的任何链接时出现的错误消息的图像（显示和编辑/保存按钮与创建新页面一起工作，但删除只是导航页面。

routes.rb文件代码：
Rails.application.routes.draw do
#get 'welcome/index' <- commented this out from earlier step in tutorial
