Exporting data from Pivotal Tracker is a pain in the ass. The following scripts let you download all the stories of a given project, and then (optionally) extract all the attachments linked to those, and download them
"""Download stories of a Pivotal Tracker project.
You need the project ID (an int) and your API token. The latter can be
obtained in ``https://www.pivotaltracker.com/profile``, or using curl::
$ curl -u username:password -X GET https://www.pivotaltracker.com/services/v3/tokens/active

Created April 23, 2013 23:18
Django model mixin to force Django to validate (i.e. call `full_clean`) before `save`
class ValidateModelMixin(object):
"""Make :meth:`save` call :meth:`full_clean`.
.. warning:
This should be the left-most mixin/super-class of a model.
Do you think Django models ``save`` method will validate all fields
(i.e. call ``full_clean``) before saving or any time at all? Wrong!

Decode session data, no matter what hashes say. It helps in some cases where the Session.get_decoded method returns an empty dictionary because it is "suspicious" of user-data tampering. Based on source code from the Django project.
