请理解我不熟悉英语。
我正在用Rails创建一个示例应用程序。由于某种原因，当我按下micropost上的delete按钮时，出现了以下错误。error
首先，粘贴管线文件。

config/routes.rb

Rails.application.routes.draw do
  root "static_pages#home"
  get '/help', to: "static_pages#help"
  get '/search', to: 'searchs#search'
  get '/signup', to: 'users#new'
  get    "/login",   to: "sessions#new"
  post   "/login",   to: "sessions#create"
  delete "/logout",  to: "sessions#destroy"
  get '/diary',  to: "static_pages#diary"
  resources :users
  resources :microposts,          only: [:create, :destroy]
end

接下来是微帖的帖子管理页面，包括一个删除按钮。

_microposts.html.erb

<li id="micropost-<%= micropost.id %>">
  <%= link_to gravatar_for(micropost.user, size: 50), micropost.user %>
  <span class="user">
   <%= link_to micropost.user.name, micropost.user %>
  </span>
  <span class="content">
   <%= micropost.content %>
   <% if micropost.image.attached? %>
      <%= image_tag micropost.image.variant(:display) %>
   <% end %>
  </span>
  <span class="timestamp">
    Posted <%= time_ago_in_words(micropost.created_at) %> ago.
    <% if current_user?(micropost.user) %>
      <%= link_to "delete", micropost, data: { "turbo-method": :delete,
                                                turbo_confirm: "You sure?" } %>
    <% end %>
  </span>
</li>

一种包含销毁方法的微柱控制器。

app/controllers/micropost_controller.rb

class MicropostsController < ApplicationController

    before_action :logged_in_user, only: [:create, :destroy]
        before_action :correct_user,   only: :destroy

    def create
     @micropost = current_user.microposts.build(micropost_params)
         @micropost.image.attach(params[:micropost][:image])
          if @micropost.save
           flash[:success] = "Micropost created!"
           redirect_to diary_path
          else
           @feed_items = current_user.feed.paginate(page: params[:page])
           render 'static_pages/home', status: :unprocessable_entity
          end
    end
  
       def destroy
         @micropost.destroy
         flash[:success] = "Micropost deleted"
        if request.referrer.nil?
         redirect_to root_url, status: :see_other
        else
         redirect_to request.referrer, status: :see_other
        end
       end
    
     private

    def micropost_params
      params.require(:micropost).permit(:content, :image)
    end

    def correct_user
      @micropost = current_user.microposts.find_by(id: params[:id])
      redirect_to root_url, status: :see_other if @micropost.nil?
    end
  end

模型

app/models/micropost.rb

class Micropost < ApplicationRecord
  belongs_to :user
  has_one_attached :image do |attachable|
    attachable.variant :display, resize_to_limit: [500, 500]
  end
  default_scope -> { order(created_at: :desc) }
  validates :user_id, presence: true
  validates :content, presence: true, length: { maximum: 140 }
  validates :image,   content_type: { in: %w[image/jpeg image/gif image/png],
                                    message: "must be a valid image format" },
                                    size:         { less_than: 5.megabytes,
                                    message:   "should be less than 5MB" }
end

我在这个网站上发现了一个类似的问题，答案是“JS有缺陷，请将此添加到您的Gemfile或JS文件中”。

js文件。

app/assets/config/manifest.js

//= link_tree ../images
//= link_directory ../stylesheets .css
//= link_tree ../../javascript .js
//= link_tree ../../../vendor/javascript .js

//= require jquery      *< add this.*
//= require jquery_ujs  *< add this.*

我遵循了这一点，但错误并没有消失。
我觉得路由、控制器、链接等设置不对，但有没有瑕疵？还是j Query？顺便说一句，我懂javascript的语法，但我是个业余爱好者。
