Ruby on rails 用于生成下载文件的控制器正在开发中，但在Heroku上失败

我有一个在我的开发环境中工作的控制器。它是由用户单击链接并生成.rdp进行下载而触发的。在我的开发环境中工作，但是，当尝试在Heroku上使用它时，我被重定向到根页面

我刚刚对heroku进行了git推送，它告诉我一切都是最新的

您无需将其写入文件即可发送，只需立即将其与send_数据一起发送即可：

你确认你运行的是相同版本的Ruby吗？你对生产环境有什么不同于开发的限制吗？从我目前的阅读来看。。。看起来我需要沿着{RAILS\u ROOT}/tmp/的行指定一些内容，这样我就可以写入Heroku/tmp/目录。但是我需要找出正确的语法，这个解决方案仍然不起作用。还在做heroku的重定向。不过它在开发环境中也可以工作。显示控制器的完整源代码之后，您可能有一个筛选器阻止它运行。这是整个控制器-筛选器之前的两个筛选器之一：authenticate\u user！，加载和授权资源导致发生此重定向。你可能没有登录到Heroku版本。我99.9%确定我没有做错。我刚刚在heroku上加载了你的版本。我已经注销，重新登录，刷新，甚至尝试在另一个浏览器。。。它仍在重定向。
