我在我的rails应用程序中使用tom-select（使用Stimulus）动态创建一个“Vendor”模型记录，然后在我的“Trx”模型的下拉列表中选择它。我可以获取创建记录的获取请求，但我的下拉列表没有更新。在12：14的时间点this SupeRails #17 video之后，他的网络选项卡显示2个项目：一个fetch，和一个xhr。在我的应用程序中，我只看到一个fetch项目（状态为200）。
我需要做些什么才能让下拉菜单填充新创建的记录？
下面是我的vendor_select_controller.js中TomSelect示例的设置：

settings = {
      plugins: ['clear_button'],
      selectOnTab: true,
      valueField: 'id',
      labelField: 'name',
      searchField: 'name',
      sortField: { field: "name", direction: "asc" },
      create: function (input, callback) {
        const data = { name: input }
        const token = document.getElementsByName("csrf-token")[0].content;
        fetch('/vendors', {
          body: JSON.stringify(data),
          method: 'POST',
          dataType: 'script',
          credentials: 'include',
          headers: {
            "X-CSRF-Token": token,
            "Content-Type": "application/json",
            "Accept": "application/json"
          },
        }).then((response) => { return response.json() })
          .then((data) => { callback({ value: data.id, text: data.name }) })
      },
      onItemAdd: function () {
        this.setTextboxValue('');
        this.refreshOptions();
      },
    }

我的VendorsController

class VendorsController < ApplicationController
...
  def create
    @vendor = Vendor.new(vendor_params)

    respond_to do |format|
      if @vendor.save
        format.html { redirect_to vendors_path }
        format.json { render json: @vendor }
      else
        format.html { render :new, status: :unprocessable_entity }
        format.json { render json: @vendor.errors, status: :unprocessable_entity }
      end
    end
  end

我的Trx表单中的Vendor collection_select字段：

<%= f.collection_select :vendor_id, Vendor.all, :id, :name, {:prompt => "Select Vendor"},
  {class: "w-full", data: { controller: "vendor-select" } } %>

控制台日志的输出：
