Default values via _updates function
Hi All,
I'm trying to do server-side created_at timestamps via CouchDB's _updates
features, but I'm having trouble creating a new document out of the JSON
passed in the request body. My app doesn't allow updates to existing
documents, only "inserts". Here's the very simple _updates function:
function(doc, req) {
var newDoc = JSON.parse(req.body);
newDoc.created_at = new Date();
return [newDoc, "FML"];
}
When I POST a document to the appropriate _updates URL, I get an error in
the log telling me that JSON is not defined:
[info] [<0.30422.5>] OS Process :: function raised error: ReferenceError:
JSON is not defined
I wasn't able to find much reference on the web aside from:
http://wiki.apache.org/couchdb/How_to_intercept_document_updates_and_perform_additional_server-side_processing
http://www.mikealrogers.com/archives/737
In the mikealrogers.com post, the author uses JSON in his function, but
obviously I'm having problems with that approach. Does anyone know what a
proper way to convert the body of the POST a javascript object would be?
(avoiding eval()). Also, taking a step back, is this the right approach
for setting default values on a new document in CouchDB?
Thanks,
Jim

What is your CouchDB version? On certain versions of CouchDB trunk (with older versions of Spidermonkey) JSON is not available in the sandbox. This is fixed in the 0.11 release. Or you can upgrade to a newer spidermonkey and I think you'll get the native JSON object.

Wow, I finally got passed that issue. Apparently it was a snafu with
upgrading from 0.10.1. This post in the mailing list
archive<http://mail-archives.apache.org/mod_mbox/couchdb-user/200912.mbox/%3C200912130717.39605.sh@widetrail.dk%3E>carried
me through. In summary, there was left over cruft from the older
install. I'm betting I would have avoided this problem if I had run `make
uninstall` while still on the old 0.10.1 branch.
The test suite is passing now, so I'm back to my original goal of adding
default fields to new documents. This JSON.parse() function is available
and working now (yay!).
The next immediate problem I see is that by POSTing new documents through
the update function, I lose the convenience of an _id property being added
automatically by couch. So the first document I created through the _update
function has an empty string for it's _id. *forehead slap*
Next thing to look for is an easy way to get a uuid from within the _update
function for setting on the _id property of my new document.
Thanks for the help,
Jim

hmm. Might be worth investigating your toolchain. Trunk is very stable right now (1.0 release candidate) so if it's not working for you, that's a sign of something wrong on your end. (I hope!)
Are the Futon tests passing on trunk for you?

Re: Default values via _updates function

I tried building from the *trunk* branch on the git mirror, specifically:
commit e13a88b46cfad2603c636cf5781469f25e9d365f
Author: Jan Lehnardt <ja...@apache.org>
Date: Mon Mar 1 19:46:19 2010 +0000
Add RC note
And I got stuck with a completely new issue: Trying to create/save a
document results in the "attempted upload of invalid JSON" error every time.
[error] [<0.5552.0>] attempted upload of invalid JSON
{"_id":"c21df46f6ad441613897517c085114a6","_rev":"1-c9a66d15ed47ea129687e645ae3ce9d2","service":"test","body":"foo","created_at":"2010-03-01
09:52:32 -0500"}
So I'm about to roll back to 0.10.1 and try just applying that simple patch
you suggested.
Fingers crossed.
Thanks,
Jim

You could also try applying this 1 line patch:
http://github.com/apache/couchdb/commit/82ff1a2b0a15dbe181221173f3013befab68f499
If you are running from a release package and not source, you'll be editing the file
/usr/local/share/couchdb/server/main.js
(you can tell you're in the right place because it'll say "do not edit this file by hand" at the top. Don't worry about that, it's just warning that your changes will be blown away by future couchdb installs. (which will have the patch)
Let us know how it goes.

Re: Default values via _updates function
Posted by Jim Garvin <co...@gmail.com>.
*Chris,*
Thanks for the response.
$ couchdb -V
couchdb - Apache CouchDB 0.10.1
Judging by the CouchDB downloads
page<http://couchdb.apache.org/downloads.html>,
I'm on the latest stable release. I was trying to get a sense of how far
off 0.11 is, so I referred to the road
map<http://couchdb.apache.org/roadmap.html> which
looks like it might be out of date, and then to the JIRA
issues<https://issues.apache.org/jira/secure/IssueNavigator.jspa?reset=true&mode=hide&sorter/order=DESC&sorter/field=priority&resolution=-1&pid=12310780&fixfor=12313841>
for
0.11, which didn't really help either.
Is CouchDB a project where it would be ill-advised to run on "edge" to get
some 0.11 features early? I'll try just updating SpiderMonkey, as you
suggested, first.
Thanks much.
*Mario*,
Also, thanks for the response. As a shot in the dark, I had tried parseJSON
first to no avail.
Thanks again to both,
Jim

Hi Jim,
I think you do not have the JSON-Class in Place at this point.
Try using parseJSON instead. (according to json2.js - file)
