Subject Change document in validate_doc_update
Date Tue, 17 Sep 2013 14:29:58 GMT
I'd like to add extra fields to the document being created, just like how
_user works.

These I'd like to be able to compute using the inputs provided by the user,
in perhaps, something like a validate function.

I tried doing the following, in many different variations, knowing well
that this is only wishful thinking... and as expected, it didn't work:

function (newDoc, oldDoc, userCtx) { newDoc['newField'] = 10; return
newDoc; }

But I'd very much like to do what the _user database does - where by
setting password, the document ends up getting different fields. How is it
achieved? How can end users like me achieve the same for my business logic
and altogether bypass the need to write middleware code? (I'm having to
write middle ware code just to transform one json hash into another because
my system is a pure API. CouchApps won't just do it (complex,
already-existent-clients will use the API)).
