request.remote\_ip is, as mentioned above, what you’re looking for within Rails. User agent, referer, etc, can all be gained from the request object. ---

hi, i was wondering is this something i would do if for example i have a rating system on my site and would like to allow the public to rate the item only once, i can log their ipaddress in a table after they rate? so if ipaddress is in table for a rating, i do nothing or display a “thanks for rating” message? thanks. ---

so i guess the easiest way to get around this is to maintain a registration table with user/pw like acts\_as\_authenticated?

If your app runs proxied under Apache use this: request.env[‘HTTP\_X\_FORWARDED\_FOR’] Direct requests: request.env[‘REMOTE\_ADDR’] You realize most your AOL (and other large ISPs) visitors will appear to be coming from the same IP addresses right? – Greg D.

You might go ahead and store the IPs but then also take into account the time span since the last rating was recorded. If it’s less than 24 hours ignore it or whatever. That’s sorta what I do in my free image rating script: [http://destiney.com/php#Destiney\_rated\_images](http://destiney.com/php#Destiney_rated_images) – Greg D.
