What are projects using for file upload? Paperclip?
Carrierwave?

Most continue to use Paperclip, though a few projects have
successfully used Carrierwave. Carrierwave apparently has better mongo support.

I tried to setup ruby and rails, and installed the latest
mysql gem and I get warning messages about the mysql gem.

Others have experienced this too and offered to help. The main answer
seemed to be “the warnings are lies, it will work.”
