acts_as tree, nested_set, something custom? Which would be best for my situation?
I''m creating a hierarchical tag structure for my portfolio. I have a
few top level tags. those could then have children, those children could
then have children. Pretty standard so far.
Often a child tag will be under more than one parent (i.e. a child might
belong toone or more parents) and it wouldn''t necessarily have the same
children under one parent as it would in another.

Rails 3.1.1 why public/system content is not transferred upon deployment
Testing locally I uploaded files into public/system/... folders
( default for Paperclip)
Upon deployment ( capistrano) on the remote server, I can see a
symlink from public/system to the shared/system/ but the content
( all images ) is not transferred.... I had to do it myself via
ftp ..
Is it a standard behavior ? or did I miss adding a task in the
deployment ?
thanks for your feedback
