Hi Guys. I want to generate QR codes in ruby on rails, to run in the background of my website written in rails. Saw this http://code.google.com/p/qrcode-rails/ but cannot work out how I could get this to work for me. Basically in RoR I want to:
Pass a generator a string, my unique code, a 20 character length number (e.g. 32032928889998887776) and have an image generated with the name 'code'_qr.jpg and saved in a resource folder to be attached to an email that my program will send out.
How would I do this, does anyone know?
And while I'm asking (not so important that I get this answer now) but how would I implement QR code reading in, to get that code back, from a web cam? Thanks.
