Rails - Jan 2007 - Capistrano and uploads to the public directory

I need some help.  I (finally) have an app setup for capistrano
deployment.  The only issue is that the admin interface allows uploads
of some file to the public directory.

When capistrano does a deploy, I get a brand new public directory,
wiping out all the uploaded files.

I am sure other have ran into this before, there must be a solution.  I
thought about putting all the uploaded file in the same spot, but the
uploads have different purposes in multiple areas and would be awkward
to simply group them into some articficial "uploads" directory that
gets
symlinked in.

Any ideas?

You''ll want to create a shared dir in the system/shared directory
capistrano sets up for you.

You can add this directory and make use of capistrano''s callback, the
after_update_code which runs after it checks out a new release into
the releases dir to re-link this every time.

You can do something like this:

desc "Tasks to execute after code update"
task :after_update_code, :roles => [:app, :db] do

  # relink a shared public directory
  run "ln -nfs #{deploy_to}/#{shared_dir}/uploads
#{release_path}/public/uploads"
end

That way you now have a symlink similar to how it handles your log directory.

Hope that helps,

Capistrano automatically creates a symlink:

   RAILS_ROOT/public/system -> RAILS_ROOT/../shared/system

To build on this, I add symlinks to the repo, so in this case:

   RAILS_ROOT/public/uploads -> RAILS_ROOT/public/system/uploads

I them set svn:ignore on public to ignore ''system'', and create
a non-
svn controlled directory in the working copy, in this case:

   mkdir -p RAILS_ROOT/public/system/uploads

I find this more convenient, reliable, and traceable than creating  
symlinks on-the-fly via Capistrano.

Charles'' method is also perfectly reasonable.

Well, I recommend creating a directory called "uploads" in your
"shared"
folder in your capistrano directory and uploading them there. If you 
allow people to upload directly to your released app''s public
directory,
then when you deploy a new revision, all those uploads will be archived. 
If you instead upload them to the shared folder, you can use custom 
routes to display them using send_file.

Because you said they have different purposes in multiple areas, I see 
the format like this:

:area/:file

For a simple one. You can forward that route to a controller which will 
then load the data from the shared folder, and use send_file to send it 
directly to the browser, as if that file were really located at the 
requsted URL.
