Yep. Sometimes it is useful. But i think not in this case, because insert/update already happened. So i am doing another PUT/POST to update the document. I talk about document processing with server side logic before insert. For example i want to know which document is last in my DB based on some criteria. How to achieve that ? My _view is giving me all records with doc.name = "test", but which of those "test" documents is last? I can use date ofc. But using date as criteria is dangerous since date is outside server logic. Something/someone can change it. So last documents will not be last. ________________________________ From: Nils Breunese <[email protected]> To: "[email protected]" <[email protected]>; N/A N/A <[email protected]> Sent: Thursday, November 3, 2011 3:59 PM Subject: Re: couchdb: function eval on insert, update...

Maybe you can use this to solve your use case?
