Accepting file uploads in web applications is very delicate, because all actions for dealing with attachments are slow:
I’m really excited about this. I’ve just released Shrine, a new solution for handling file uploads in Ruby applications. It was heavily inspired by Refile, most notably its idea of backends. However, unlike Refile, it is designed primarily for upfront processing (as opposed to on-the-fly). It’s also inspired by CarrierWave’s idea of uploaders.
When developing gems, often one of the difficult problems to solve is creating a good ratio between simplicity, convenience and flexibility.
