Capistrano未部署回形针图像

Question

I have a Rails 4 app using the paperclip gem to store images at #{Rails.root}/public/system/... which works fine in development.

I have checked a handful of the development images into the above folder, but they aren't appearing on the Ubuntu 13.10 EC2 instance that I am deploying to. I am using Capistrano to deploy, and it seems to be creating all the symlinks fine:

ls -l releases/20140402123457/public/system lrwxrwxrwx 1 ubuntu ubuntu 28 Apr 2 12:35 releases/20140402123457/public/system -> /var/www/alpha/shared/system

But the shared directory being linked to does not contain my images. How do I populate the /var/www/app/shared/public/system directory? I assumed Capistrano would do this for me, but it is empty.

I have searched many capistrano / paperclip threads for the answer, and I have tried all the capistrano deploy commands I can find in Capistrano -T. I believe I am using default locations for paperclip, and the paperclip documentation suggests the path I am using: https://github.com/thoughtbot/paperclip#understanding-storage

My Gemfile.lock shows the Gems I am using here: http://pastebin.com/iDv1Qm5K .

I've been scratching my head and am staring to wonder if I am going mad. Do I need to manually copy the development images into the shared/system directory? I have checked the images are in git and are extracted when cloning, so I am hoping I have covered the basics on daft mistakes that could be causing this. Any advice on how to investigate this further would be much appreciated.

Answer 1

Thanks to the tips from Marian Theisen, I have fixed this by moving the seed image files from the /app/public/system directory to /app/assets/seed_images/.

I then created a cap deploy task in config/deploy.rb to copy the images over to the shared directory:

namespace :deploy do desc "Move seed images into place" task :move_seed_images_into_place, :roles => :app do run "cd #{release_path}; cp -R app/assets/seed_images/* #{shared_path}/system" end end

And added after("deploy:update_code", "deploy:move_seed_images_into_place") to my config/deploy/staging.rb file.

In short, the answer is that I was doing the wrong thing by trying to share public/system between my dev machine and staging hosts. Instead, I have moved the seed images to a named location and I manually move them into place on my staging hosts.

This also has the benefit that I can trash the images I am using in development without trashing the install - I have a snapshot of the images I want saved in the app/assets/seed_images directory.
