Rubyonrails Rails 7中的Turbo流

我一直在关注这个教程https://www.youtube.com/watch?v=TKIbtbYyRdE&list=PL6SEI86zExmvb4qjVHJWrKRQrKjWksQ81&index=34，然后是它的第二部分 https://www.youtube.com/watch?v=akrXCho2m6Y&list=PL6SEI86zExmvb4qjVHJWrKRQrKjWksQ81&index=34

我受够了试图找出问题出在哪里，

<%= link_to "Connect", connections_path, class:"btn btn-primary", data: { controller:"connections", turbo_method: :post, requester_id: current_user.id, connected_id: user.id, connections_target:"connection" } %>

上面的link_to使用StimulusJS控制器"连接"，它应该执行POST请求

Connections_Controler.js

import { Controller } from "@hotwired/stimulus";

// Connects to data-controller="connections"
export default class extends Controller {
 static targets = ["connection"];

 connect() {}

 initialize() {
 this.element.setAttribute("data-action", "click->prepareConnectionParams");
  }

 prepareConnectionParams(event) {
    event.preventDefault();

 this.url = this.element.getAttribute("href");

 const element = this.connectionTarget;
 const requesterId = element.dataset.requesterId;
 const connectedId = element.dataset.connectedId;

 const connectionBody = new FormData();

    connectionBody.append("connection[user_id]", requesterId);
    connectionBody.append("connection[connected_user_id]", connectedId);
    connectionBody.append("connection[status]", "pending");

    console.log("Connection Body:", connectionBody);

 fetch(this.url, {
      method: "POST",
      headers: {
        Accept: "text/vnd.turbo-stream.html",
 "X-CSRF-Token": document
          .querySelector('meta[name="csrf-token"]')
          .getAttribute("content"),
      },

      body: connectionBody,
    })
      .then((response) => response.text())
      .then((html) => Turbo.renderStreamMessage(html));
  }
}

之后，我有ConnectionsController.rb

class ConnectionsController < ApplicationController 
  before_action :authenicate_user!
 
 def create
 Rails.logger.debug "Params received: #{params.inspect}"

    @connection = current_user.connections.new(connection_params)
    @connector = User.find(connection_params[:connected_user_id])

    respond_to do |format|
 if @connection.save
        format.turbo_stream { 
          render turbo_stream:
          turbo_stream.replace(
 "user-connection-status",
 partial: "connection/create",
 locals: { connector: @connector }
          )
        }
 end
 end
 end

 private
 def connection_params
    params.require(:connection).permit(:user_id, :connected_user_id, :status)
 end
end

当我点击该链接时，它在控制台中显示错误400错误的开机自检请求，并刷新页面. 它不起作用，所以我使用了RAIS.LOGER.DEBUG"PARAMS RECEIVED:#{PARACES INVIST}" 因此在终端日志(log)中显示没有发送参数接收到的参数:#<ActionController::Parameters {"controller"=>"connections", "action"=>"create"} permitted: false>
