Rails.ajax - Rails未定义- Rails 7

Question

我试图遵循本教程来实现sortablejs：

https://www.youtube.com/watch?v=r884jAqAbHY

我希望通过向服务器发送ajax更新来保持状态。本教程(Rails 6)是通过Rails.ajax完成的

在Rails 7中，这会导致控制台错误：

Uncaught ReferenceError: Rails is not defined 

在Rails 7中执行异步请求的"Rails方式“是什么？

Answer 1

取工作-我不知道这是否是“铁路的方式”。。。

fetch("URL", {
  method: "PATCH", 
  headers: {
    "X-CSRF-Token": document.querySelector("[name='csrf-token']").content,
  },
  body: data,
});

Answer 2

您可以使用https://github.com/rails/request.js#how-to-use

例如：

import { FetchRequest } from '@rails/request.js'

....

async myMethod () {
  const request = new FetchRequest('post', 'localhost:3000/my_endpoint', { body: JSON.stringify({ name: 'Request.JS' }) })
  const response = await request.perform()
  if (response.ok) {
    const body = await response.text
    // Do whatever do you want with the response body
    // You also are able to call `response.html` or `response.json`, be aware that if you call `response.json` and the response contentType isn't `application/json` there will be raised an error.
  }
}
