I'm building my first website with rails,it consists of a blog, a few static pages and a photo gallery. The admin section has namespaced controllers. I also want to create a mailing list, collecting contact info, (maybe a spree store in the future too.) Should I just use basic http authentication and check if the user is admin? Or is a plugin like authlogic better, then define user roles even though there would only be two; admin and user?
