Ah, got it now. Thanks for reminding me about the update handler feature of

The doc argument comes from couch, not me. The req is what I provide.

GET the document from CouchDB, change the row appropriately, PUT it back to
CouchDB. All using HTTP. CouchDB will complain about merge problems if the

I have an update handler that I use for all updates. You just send the
change to the handler and it reads the doc, updates it, and writes it back,
all in one http request. I can even update items nested in objects and
arrays using a syntax like /a/b/c:newValue. I also support deleting
fields at
I'd be happy if I were wrong, but I don't believe it's possible to do all
that with one HTTP request in CouchDB. The read and the write require at
least two requests, a GET and a PUT as Bradley suggests...

Here is the update handler. As you can see it does what I claimed. Enjoy
...
update: (doc, req) -
postData = JSON.parse req.body
if doc
for k, v of postData
hash = doc
if k[0] is '/'
parts = k.split '/'
for part in parts[1..-2] then hash = (hash[part] ?= {})
k = parts[-1..-1][0]
if v is
Thanks for sharing. :) I had assumed that the OP didn't still have the
original document hanging around in memory, as your doc argument
suggests. Hence the need to GET it before updating.
