Contacts is a project mainly written in JAVASCRIPT and PYTHON, it's free.
Example Contacts app for SproutCore and FormView. Growing slowly. See demo :)
(I add .app for no reason)
It is very work in progress; you can barely count it as functional!
For awhile, you had to actually download two components and start three servers manually. Now, as long as you have a few prerequisites, everything should work!
If you just run sc-server in the project directory, it should already work using fixtures.
To download:
git clone git://github.com/ialexi/Contacts contacts
To initialize all submodules and set up the sample database:
cd contacts python contacts.py setup
It will show everything it does.
Now, change apps/contacts/core.js to enable the back-end by uncommenting the line for the django back-end.
To run:
python contacts.py start
And it should now be running! contacts.py starts all three servers (sc-server, Dobby, and django).
sc-server will proxy both the Comet server and the Django server. You should be able to open up two browser windows to: http://localhost:4020/contacts
If you change something in one, the changes should automatically appear in the other. There are some issues with deleting contacts (refreshing fixes these).
Good luck. :)
