I would like to create a simple file repository in Ruby on Rails. Users have their accounts, and after one logs in they can upload a file or download files previously uploaded.

The issue here is the security. Files should be safe and not available to anyone but the owners.

  1. Where, in which folder, should I store the files, to make them as safe as possible?
  2. Does it make sense, to rename the uploaded files, store the names in a database and restore them when needed? This might help avoid name conflicts, though I’m not sure if it’s a good idea.
  3. Should the files be stored all in one folder, or should they be somewhat divided?

    • rename the files, for one reason, because you have no way to know if today’s file “test” is supposed to replace last week’s “test” or not (perhaps the user had them in different directories)
    • give each user their own directory, this prevents performance problems and makes it easy to migrate, archive, or delete a single user
    • put metadata in the database and files in the file system
    • look out for code injection via file name
