How to add IP address field to documents

[Pulkit Singhal <pu...@gmail.com>]

I would like to add an additional field to incoming documents in the
validate_doc_field method. This field should store client info like the IP
address. I hope that folks reading this thread find this to be same as
adding a created_at or last_modified timestamps. And ofcourse the minor
difference is that timestamps can be generated but for something like
client ip address, it would have to be picked-up/passed-in from somewhere.

I'm using CouchDB 1.2.0 and I'm used to the following method signature:
function (new_doc, old_doc, userCtx) {...}

But while Google~ing I have found two threads that hint at the existence of
a different validation signature:
  1.
http://grokbase.com/t/couchdb/user/094xjv2zaz/validate-doc-update-modifying-doc
  2. https://issues.apache.org/jira/browse/COUCHDB-1287

Does this new signature actually exist in 1.2.0 or not?
function (new_doc, old_doc, userCtx, http_headers) {...}

Overall are there any suggestion on how to add an IP address field to
documents on the fly?

The signature for validate_doc_update is;

(newDoc, oldDoc, userCtx, secObj)

The request is not exposed (and thus you can't find the IP of the client).

Hi Pulkit,

You cannot modify documents in the validate_doc_update function--their
purpose is solely to check whether a document is valid. However you could
use an _update handler:

http://wiki.apache.org/couchdb/Document_Update_Handlers

Note the second parameter to that function is the request object, from
which you should be able to get the client's IP address.


Cheers,

Zach
