  • Discard

    🃏🗑 Soft deletes for ActiveRecord done right

    discard - a soft-delete implementation that avoids a lot of the gotchas associated with paranoia or acts_as_paranoid gem.

  • CanCanCan

    The authorization Gem for Ruby on Rails.

    It fails deadly -- forgetting to pass an instance grants unintended access, and this problem is so bad they have a document explaining how to avoid it. If you use a permission in an unintended way, it should not grant access.
