====================
Django's data portal
====================

Inspired by David Eaves, here's some information on accessing Django's 
contribution data. 

.. contents:: What's available:

Please take it, mash it up, and let show us the results!

If there's other data you'd like to see, please get in touch (``jacob -at- jacobian.org``) and let me know what you'd like to see. I'll do my best!

Trac's database
===============

Data dumps out of Trac, our ticket tracking software.

There's two ways to access the data: `Trac's RPC interface`_ and the `daily
data dumps`_.

Trac's RPC interface
--------------------

Trac has a XML-RPC and JSON-RPC interface. You view some documentation of these
APIs at::

    https://code.djangoproject.com/xmlrpc

.. note::

    **You'll need to be logged in to access this page** and to access the data. If you need to create an account, the sign-up page is at https://www.djangoproject.com/accounts/register/.

The base URLs you'll use for for the XML-RPC and JSON-RPC APIs is::

    https://{username}:{password}@code.djangoproject.com/login/rpc

The easiest way to access these APIs is with Python's `xmlrpclib`_ library.
Here's a quick example::

    >>> import xmlrpclib
    >>> rpc_url = "https://USERNAME:PASSWORD@code.djangoproject.com/login/rpc"
    >>> trac = xmlrpclib.ServerProxy(rpc_url)

    # Get a single ticket's info.
    >>> ticket, time_created, time_changed, attributes = trac.ticket.get(1337)
    >>> attributes['resolution']
    'wontfix'

    # Perform a search. - counts the open (i.e. not-closed) tickets.
    # Query syntax is documented at http://trac.edgewall.org/wiki/TracQuery#QueryLanguage
    >>> not_closed = trac.ticket.query('status=!closed&max=5000')
    >>> len(not_closed)
    1850

Please be careful here. There are APIs that write data and using them could 
look like spam, so please ask me (``jacob -at- jacobian.org``) for permission 
first!

Daily data dumps
----------------

These are direct data dumps of the Trac database, collected nightly, in various
formats. They're sanitized to remove some tables with senstive info (session
data, etc.) but are otherwise complete.

Dumps are currently available in the following formats:

    * CSV_ (tar'd & bzipped directory; one CSV file per table; ~35MB).

.. _csv: https://www.djangoproject.com/m/data/django-trac-csv.tar.bz2

The database schema is documented at
http://trac.edgewall.org/wiki/TracDev/DatabaseSchema. The most interesting
tables are probabably the ``ticket`` and ``ticket_change`` tables.
``ticket_change``, in particular, contains each change ever made to a ticket 
and so probably has some of the most itnersting data available.

Mashups
=======

If you create a mashup, please add it here!

    * `Django Development Dashboard`_ (by JKM).
