Selecting a subset of a collection

yoann.aubin...@gmail.com (Yoann Aubineau) — Thu, 21 Jan 2010 17:08:06 UT

Hi Jon,
I just came across Cloudkit, so maybe I still don't get everything.
Congratulations for such a great piece of software, by the way.
I was wondering if there is any way to select a subset of a
collection. Let's say I want all blog posts whose author name starts
with "Jo" or all new products added from January 1st, or all invoices

I don't have a definite date for the next release, but I can give you a
snapshot of its progress. The JSON bridge that is being used has been
extracted as its own project, published as "snarl" under my user account
(jcrosby) on GitHub. The next piece, the JavaScript storage engine, is
working with its own in-memory adapter but has not been published because I

Much better! Thanks a lot for your reply. I'll have a look at the
jsonquery branch.

I guess the next question is... how long till the next release
then? :-)

This is correct. At one point, CloudKit did use SQLite for the default
store, moving to DataMapper for a while so that other databases could be
used.

The in-memory adapter is the only other one available today, but that will
change in the next release.

To make this work for the current release, one could either extend the

I spent a while looking at this group, Cloudkit docs, examples etc.
and -- PLEASE do correct me if I'm wrong! -- I realized that the only
way Cloudkit can persist data to disk seems to be through Tokyo
Cabinet, while some time ago it was also possible to use SQLite or
MySQL...

While I do like Tokyo cabinet, I'm not 100% happy because it's not

Hi Jon,
thanks for the answer. I'll try to do it in the next couple of days.
My final goal to get it working under google appengine.
The mapping of key store to the bigtable shouldn't be too complicated.
And after jsonquery and jsonschema things are working :) it will get
me everything I need.
Thanks,

Maksym,

The quickest way to get it working is to first install the regular gem. This
will fail on the native extension gems, but will take care of everything
else. Next, check out the jsonquery branch on GitHub and install json-jruby
as you noted. At that point, you should be able to run "rake" at the root of

Hi Jon, Neville,

I'm trying to install the cloudkit gem under jruby, but it still tries
to compile the json gem, and, obviously, fails. I tried to install
json_jruby and json_pure before, but it doesn't change the error.

How did you manage to get it working ?

Maksym

Re: [cloudkit] Sub selection of JSON document via URI

jon.r.cro...@gmail.com (Jon Crosby) — Mon, 07 Sep 2009 15:51:13 UT

We discussed this in IRC, but I am replying on the mailing list for
everyone's benefit. Basically, JSONQuery will handle this on the server side
once I merge those changes into the master branch. JSONQuery already
provides this functionality on the client side via the jQuery plugin,
jquery.cloudkit.js. The JSONQuery expression to extract the value of foo

marak.squi...@gmail.com (Marak Squires) — Sun, 06 Sep 2009 11:42:43 UT

Is it possible to query the JSON document inside a collection from the
URI?

For example, if I have a collection at: '/data'

And I have the following document: '/data/4b1953c1-7d03-012c-
a18b-4040f67bf8d1'

Which contains the JSON: '{"foo": "bar"}'

How could I perform a GET on a URI like: "/data/4b1953c1-7d03-012c-

Oh so that's why my message didn't appear on the list - damn confusing web
interface :)
Anyways...
My understanding of rack middleware is all theory for the time being.
For now I'm just going to keep things the way they are.
I'll keep my eye on CloudKit and see what comes up
Thanks for the reply Jon,

Re: [cloudkit] Multiple records / Bulk POST inserts

jon.r.cro...@gmail.com (Jon Crosby) — Mon, 31 Aug 2009 13:46:45 UT

Bulk inserts are not supported in the current API, but they are on the list
of planned features in the TODO list at the root of the project repo. Given
the current state of the code, bulk inserts should be fairly straightforward
to implement. Result bodies from the bulk operations would look like the

marco.lazz...@gmail.com (Marco Lazzeri) — Mon, 31 Aug 2009 13:27:29 UT

Hi,

Is there any support for multiple records insertion with a single POST
request?

I'm thinking about something like:

$ curl [link] -X POST -d '[ { "name" : "foo" },
{ "name" : "bar" } ]'

Where { "name" : "foo" } and { "name" : "bar" } are 2 different
documents being inserted.

Hi Jon,

Thanks for your reply.

FYI, cloudkit + json_pure.gem works jun fine under JRuby.

I'll also take a look at json_jruby also.

jon.r.cro...@gmail.com (Jon Crosby) — Tue, 18 Aug 2009 00:44:06 UT

Neville,
If you install the json-jruby gem, CloudKit should work under JRuby. If not,
please let me know. All of the specs are passing for me locally after
installing that gem (using JRuby 1.3.1). I'll update the gemspec so that it
chooses the correct one when installed with jgem.
