Rails 4，资产管道导致用户可下载文件被下载两次 [英] Rails 4, asset pipeline causes user downloadable files to be downloaded twice

问题描述

我的应用程序目录中有一个名为"uploads"的文件夹，用户可以在其中上传文件和下载文件.我不希望上载文件夹位于公共目录中，因为我想控制下载授权.

I have a folder in my app directory named "uploads" where users can upload files and download files. I don't want the uploads folder to be in the public directory because I want to control download authorization.

在我的控制器中，我有:

In my controller, I have:

send_file Rails.root.join('app', 'uploads', filename), :type => 'application/zip', :disposition => 'inline', :x_sendfile=>true

这实际上很好.问题是，当我在生产服务器上时，当我运行rake asset:precompile并具有一个Assets目录时，该文件将下载两次.首次下载文件时，浏览器的运行就像什么都没有发生(没有加载旋转)一样，但是我看到数据正在Google Chrome Web开发人员的网络"标签中传输.然后，在下载文件之后，出现提示，询问用户是否要下载文件.

This actually works fine. The problem is that when I'm on the production server, when I run the rake assets:precompile, and have an assets directory, the file downloads twice. The first time the file downloads, the browser acts as if nothing is going on (no loading spinning), but I see data being transferred in the Google Chrome web developer Network tab. Then after the file has been downloaded, a prompt comes up asking the user if he/she wants to download the file.

删除公用目录中的资产文件夹可以解决此问题，但是我想使用资产管道.我还尝试过将资产管道需求从require_tree更改为require_directory.

Removing the assets folder in the public directory gets rid of this problem, but I want to use the asset pipeline. I also tried changing the asset pipeline requires from require_tree to require_directory.

有人知道如何使send_file与资产管道正常工作吗?

Does anyone know how to get send_file working properly with the asset pipeline?

谢谢.
