Paperclip文件在每次部署后都会被删除 [英] Paperclip files get deleted after each deploy

问题描述

我使用Paperclip宝石来存储图片，而在localhost上，它是完美的。但是，我添加到我的直播应用程序的任何图片都会在每次部署后被删除。

I use the Paperclip gem to store pictures, and on localhost it works perfectly. However, any pictures I add to my live app get deleted after every deploy.

我使用Git进行部署。这是我的部署过程：

I use Git to deploy. Here's my deployment process:

$ bundle exec cap production deploy
$ ssh [e-mail]
$ chmod -R 777 /rails_apps/app/releases
$ cd /rails_apps/app/current
$ cp config/database.yml.sample config/database.yml
$ RAILS_ENV=production bundle exec rake assets:precompile
$ /etc/init.d/apache2 restart

有没有人遇到这样的事情？

Has anyone else run into something like this?

更新：

这不是重复的，因为这个问题的答案，这是将此行添加到我的deploy.rb：

This is not a duplicate, because the answer to this question, which is to add this line to my deploy.rb:

set :linked_dirs, fetch(:linked_dirs, []).push('public/system')

导致Paperclip完全打破。以前，我没有权限使用Paperclip添加图像，导致了以下错误：

causes Paperclip to break entirely. Previously I had had an issue with not having permission to add images with Paperclip, resulting in this error:

Errno::EACCES in UsersController#update
Permission denied - /rails_apps/website/releases/20150807211111/public/system/users/avatars/000/000/562

但是在我的服务器上运行这个命令修复了权限：

But running this command on my server fixes the permissions:

chmod -R 777 /rails_apps/website/releases

但是，如上所示修改我的deploy.rb文件， code> chmod -R 777 命令不再工作，我再次没有权限添加图像，导致相同的权限被拒绝错误。

However, modifying my deploy.rb file as shown above, causes the chmod -R 777 command to no longer work, and I once again don't have permission to add images, resulting in the same "Permission denied" error.

所以这个问题不能为我的问题提供一个有效的解决方案。

So that question does not supply a valid solution to my problem.

推荐答案

在这里：

set :linked_dirs, fetch(:linked_dirs, []).push('public/system')

是实现y将您的公共/系统文件夹从 / rails_apps / website / releases / 20150807211111 / public / system 链接到 / rails_apps / website / shared / public / system ，使图片始终存储在共享目录中，而不会在部署时丢失。所以你应该实际做的是为共享文件夹设置适当的权限。

is actually symlinking your "public/system" folder from /rails_apps/website/releases/20150807211111/public/system to /rails_apps/website/shared/public/system , so that the pictures are always stored in the shared directory, and not lost on deploy. So what you should actually do is set the proper rights for the shared folder.
