Offline Django Apps

installable application. I recently read about Joyent Slingshot:
http://developer.joyent.com/
I'm curious if there are others who could use this functionality but
for Django. If so, perhaps we can all collaborate and come up with a
solution that runs on Mac, Windows, and Linux. Data syncing would be
nice but can come later.
A big bootstrap and proof of concept is most definitely DjangoKit:

I'd be interested, certainly. Not sure I have much to contribute in
the way of desktop programming skills, but I can think of more than a
couple uses for such a thing and I'll happily do whatever I can.

start with?
Coming up in the next month or so I'm going to have to dedicate work
time to this but for now I'd like to just lay out the groundwork and
do it in such a way that it benefits the Django community.
1) Cross Platform Libraries...
In looking at DjangoKit a little I see he's using PyObjC. I do like
the idea of using whatever the native widget library is for each
platform. I'll have to look at the Democracy Player as an example but
they did something similar (Mac: PyObjC, Linux: PyGTK, Windows: ???).
2) Database...
It makes sense to me to require SQLite for this to work. Moving your
data to SQLite is also a requirement for Slingshot. I'm pretty sure
we can use the fixtures library to serialize data from databases other
than SQLite (MySQL, PostGreSQL), then load it up into SQLite.
3) Anything else?
Thanks,
Rob

likely to become part of the core django distro. A link from the Django
wiki is probably a good idea though.

DjangoKit is a native-widgets project, and will probably stay that
way. I very much like the idea of Windows and linux-specific native-
widget projects to complement it. The core of the thing was very easy
to write - the hardest part was getting the packaging system to
behave, so there probably won't be a lot of effort duplicated between
the platforms here.

This, on the other hand, _can_ be shared nicely. And has nothing to do
with a GUI wrapper. A framework that will do 2-way sync between 2
django applications / databases can be worked on in the absence of
working wrappers.

(a) One thing I've been finding is that many django apps I've found
aren't really written as apps, but tend to be tied very heavily to the
project they're developed in. I've only just joined django-users, so
maybe this is covered a lot. But because djangokit provides it's own
project and expects the thing you're packaging to be a stand-alone
app, it's hard to find nice demos.
(b We're going to find lots and lots of different deployed versions of
the app's DB schema in the wild, so upgrades will be nasty. With
proper 2-way sync, you could just tell the remote user to sync, blow
away their DB, then re-sync, but if you're trying to write a simple
stand-alone app, you'll need upgrade scripts.

FWIW, http://www.gnuenterprise.org/ is said to provide this kind of
functionality -- ORM, Forms running in different environments (including
web), Reports, your business logic in a separate place, everything in
Python. I didn't have the time to play more with it, so I can't tell how
that looks like, but I would be interested to see both using a common
ORM and GNUe being able to use Django as a web front-end framework.
With kind regards,

I've created a google code project - http://code.google.com/p/djangokit/
- anyone who cares is welcome to membership.

There's a lot of interesting things about Google Gears...
It provides a browser local SQLite accessible via Javascript.
It provides a local HTTP server for storing/retrieving cached content.
Simon Willison dug up some interesting Google Gears tidbits:
http://simonwillison.net/tags/googlegears/
including:
Adobe's Apollo will use Google Gears technology, Dojo was in on the
Google Gears collaboration uses it.
Looks like a lot is happening in the world of offline web
applications.
Great stuff.
