每次部署后都会删除回形针文件 [英] Paperclip files get deleted after each deploy

问题描述

我使用 Paperclip gem 来存储图片，并且在 localhost 上它运行良好.但是，每次部署后，我添加到实时应用中的所有图片都会被删除.

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

有没有其他人遇到过这样的事情?

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，就是添加这行到我的 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')

导致回形针完全断裂.之前我遇到过无权使用 Paperclip 添加图像的问题，导致此错误:

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，导致 chmod -R 777 命令不再起作用，并且我再次没有添加图像的权限，导致同样的权限被拒绝"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.

所以这个问题没有为我的问题提供有效的解决方案.

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

推荐答案

你在这里做什么:

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

实际上是将您的public/system"文件夹从 /rails_apps/website/releases/20150807211111/public/system 符号链接到 /rails_apps/website/shared/public/system ，以便图片始终存储在共享目录中，并且不会在部署时丢失.所以你应该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.
