Subject Re: Request object in validate_doc_update

Sure. For example I'm allowing my users to vote on certain "items" in
my database. This will allow me to understand the amount of
satisfaction of these items. I can easily validate and make sure each
user is commenting only once, however, someone might simply create a
new account and re-vote for that item. This defeats the purpose of the
voting system.
My solution would be to check based on the IP of the voter, no matter
what user they're logged in with.

Does this make sense? Thanks.
