删除方法rails 6

Question

我制作了一个允许用户添加编辑和删除文章的网络应用程序。我遇到的问题是删除方法不起作用。当我单击要删除的文章旁边的 "Delete" 时，没有任何反应，我也没有收到任何错误。我认为它充当 GET 方法而不是 DELETE 方法，但我不知道为什么它不起作用。

任何帮助将不胜感激！

articles_controller.rb

def destroy
  @article = Article.find(params[:id])
  @article.destroy
  redirect_to articles_path
end

index.html.erb

<tbody>
  <% @articles.each do |article| %>
  <tr>
    <td><%= article.title %></td>
        <td><%= article.description %></td>

        <td><%= link_to 'Show', article_path(article) %></td>
        <td><%= link_to 'Edit', edit_article_path(article) %></td>
        <td><%= link_to 'Delete', articles_path(article), method: :delete, data: {confirm: "Are you sure?"} %></td>

  </tr>
  <% end %>

单击删除时的控制台：

Started GET "/articles.5" for ::1 at 2020-03-26 16:45:32 +0000

routes.rb

Rails.application.routes.draw do
  root 'pages#home'
  resources :articles, only: [:show, :index, :new, :create, :edit, :update, :destroy]

end

Application.js

require("@rails/ujs").start()
require jquery
require jquery_ujs
require bootstrap-sprockets
require("turbolinks").start()
require("@rails/activestorage").start()
require("channels")

Answer 1

这是错误的。

<td><%= link_to 'Delete', articles_path(article), method: :delete, data: {confirm: "Are you sure?"} %></td>

应该是...

<td><%= link_to 'Delete', article_path(article), method: :delete, data: {confirm: "Are you sure?"} %></td>

使用文章显示路径，而不是文章索引路径。

Answer 2

我找到了解决此问题的方法。通过改变

<td><%= link_to 'Delete', article_path(article), method: :delete, data: {confirm: "Are you sure?"} %></td>

至

<td><%= button_to 'Delete', article_path(article), method: :delete, data: {confirm: "Are you sure?"} %></td>

这解决了我的问题。
