在 JS 模块中使用 Rails-UJS(带有 webpacker 的 Rails 6) [英] Using Rails-UJS in JS modules (Rails 6 with webpacker)

问题描述

我刚刚切换到 Rails 6 (6.0.0.rc1)，它默认使用 Webpacker gem与 Rails-UJS 一起用于 Javascript 资产.我想在我的一些模块中使用 Rails UJS，以便从一个函数提交表单:

i just switched to Rails 6 (6.0.0.rc1) which uses the Webpacker gem by default for Javascript assets together with Rails-UJS. I want to use Rails UJS in some of my modules in order to submit forms from a function with:

const form = document.querySelector("form")
Rails.fire(form, "submit")

在以前安装了 Webpacker 的 Rails 版本中，Rails 引用似乎在我的模块中全局"可用，但现在我在调用 Rails.fire 时得到了这个......

In former Rails versions with Webpacker installed, the Rails reference seemed to be "globally" available in my modules, but now i get this when calling Rails.fire…

ReferenceError: Rails is not defined

如何使 @rails/ujs 中的 Rails 可用于特定模块或所有模块?

How can i make Rails from @rails/ujs available to a specific or to all of my modules?

在我的设置下面...

app/javascript/controllers/form_controller.js

import { Controller } from "stimulus"

export default class extends Controller {
  // ...
  submit() {
    const form = this.element
    Rails.fire(form, "submit")
  }
  // ...
}

app/javascript/controllers.js

// Load all the controllers within this directory and all subdirectories. 
// Controller files must be named *_controller.js.

import { Application } from "stimulus"
import { definitionsFromContext } from "stimulus/webpack-helpers"

const application = Application.start()
const context = require.context("controllers", true, /_controller\.js$/)
application.load(definitionsFromContext(context))

app/javascript/packs/application.js

require("@rails/ujs").start()
import "controllers"

谢谢！

推荐答案

在我的app/javascript/packs/application.js中:

import Rails from '@rails/ujs';
Rails.start();

然后在我正在编写的任何模块、控制器、组件中:

and then in whatever module, controller, component I'm writing:

import Rails from '@rails/ujs';
