If you pass along the _rev of the *previous* version it will update as  
you expect.  See:

"To update an existing document, you also issue a PUT request. In this  
case, the JSON body must contain a _rev property, which lets CouchDB  
know which revision the edits are based on."

Otherwise, if retrieving _rev is awkward, you can DELETE and re-add.   
I don't know of a good way to handle the potential race conditions of  
either case, if this is important to avoid.  (i.e. someone else  
updates or adds your document before you get a chance to.)
