迁移到Webpack后，Rails UJS的link_to删除操作无法正常工作

Question

我有一个使用Rails/webpacker/stimulus的项目。今天我将asset pipeline迁移到了webpacker，一切都很顺利，除了一个细节。

带有调用destroy方法的link_to按钮直接跳转到show动作页面。而且，remote:true标签也不起作用了。ajax:beforeSend操作没有被触发，并且确认框也不再加载。

<%= link_to sanitize("<i class='fa fa-trash'></i>"), dashboard_manager_dashboard_path(dashboard), remote: true, method: :delete, data: {
                            confirm: "sure?",
                            action: 'ajax:beforeSend->dm--dashboard#onBeforeDelete ajax:success->dm--dashboard#onDelete'
                        } %>

我在StackOverflow上找到了许多类似的案例，大多数都提到Rails UJS没有正确加载，这似乎也是此处的情况。但这些示例中的问题并未使用webpack。

StackOverflow上的一些帖子提到要使用button_to而不是link_to。但这不是我要寻找的解决方案，我想能够使用remote:true和ajax回调。

有人看到我的设置存在缺陷吗？感谢提供任何建议！

Application.js:

import Rails from 'rails-ujs';
import Turbolinks from 'turbolinks';
import * as ActiveStorage from 'activestorage';

Rails.start();
Turbolinks.start();
ActiveStorage.start();

import "../src/import-jquery";
import 'bootstrap/dist/js/bootstrap';
import 'tempusdominus-bootstrap-4';
import '../src/bootstrap-select.js';
import '../src/custom_calender.js';
import '../src/functions.js';

import { Application } from "stimulus"
import { definitionsFromContext } from "stimulus/webpack-helpers"
const application = Application.start();
const context = require.context("controllers", true, /.js$/);
application.load(definitionsFromContext(context));

environment.js

const {environment} = require('@rails/webpacker');

const webpack = require('webpack');
environment.plugins.append('Provide', new webpack.ProvidePlugin({
    $: 'jquery',
    jQuery: 'jquery',
    jquery: 'jquery',
    Popper: ['popper.js', 'default']
}));

module.exports = environment;

这可能有点晚了，但我在学习rails时遇到了类似的问题。我发现我没有在app/assets/layouts/application.html.haml中包含以下行
= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload'
。请注意保留HTML标签。

在我的情况下，我遇到了同样的问题，这是因为我在app/javascript/pack/中创建了application.scss

如果我将 .scss 文件移动到 stylesheet 中，一切都正常了)
