I have a site that I already created and it up and running with django. It has a bunch of users. I want to create a facebook app where the user can tie in the two accounts, and have an "application tab" in their facebook profile which will basically display a bunch of information pertaining to their account on my django site. Also, when they do certain things on my site, it'll show up in their facebook feed (if they choose to allow that).
I already installed pyfacebook and have a basic running app going. The problem I'm having is figuring out how all this is going to work. Where do I have the user match the two accounts up? Do I have them put their facebook UID into my site's preferences, or do I have them enter their username on my site into the facebook app? Should I have the canvas be a "enter your [my site] credentials" page?
