Rails: is there a way to tell the source of the request?

问题

Google analytics tells me what the source of my traffic is (search engines, facebook etc). Is there a way to get this information for each request from the request object or otherwise? I'd appreciate any help.

回答1:

request.referrer will give you the HTTP referrer value.
