Javascript 调用AJAX时，Rails 6生产处理html模板代替js

在使用ajax调用时，我在生产模式下遇到rails 6.1.1和ruby 2.7.2的问题，如下所示：

视图：

create.js.erb

$('#company_follow_<%=@company.id%>').html("<%= escape_javascript(render partial: "company_follows/follow_company", locals: {company: @company})%>");

但在生产日志中为false，调用的是html模板，而不是js模板：

有人能告诉我为什么我会遇到这个问题，我该如何解决它吗？

非常感谢你

您确定rails ujs/资产在生产中已正确加载吗？如果未加载rails ujs/@rails/ujs，则所有数据远程/数据方法都将不起作用。感谢您的评论，但我已将其添加到javascripts/pack/application.js中，并且生产不起作用。//=require jquery/=require jquery\u ujs如何确认在生产中加载的rails ujs？如果它工作，那么在生产站点的浏览器控制台中，您可以输入

$。rails

，这应该会对某些内容做出响应。通常，当产品中出现资产问题时，请确保：1。您的prod系统已安装nodejs，2。

rails-assets:precompile

运行时没有错误。@stwienert，当我更改application.js文件并使用capistrano部署时，rails-assets:precompile任务将构建新的js包，rails-ujs工作成功。但是，在下一次部署中，js包没有构建，rails ujs失败。您知道如何在每个部署任务中强制重建js包吗？非常感谢。
