django-cal

Django app to enable exporting of events to iCalendar files. Imitates behavior of django.contrib.syndication and is based upon vobject (http://vobject.skyhouseconsulting.com/).

Heavy inspiration came from Christian Joergensen (http://www.technobabble.dk/2008/mar/06/exposing-calendar-events-using-icalendar-django/) and Derek Willis (http://blog.thescoop.org/archives/2007/07/31/django-ical-and-vobject/).

Installation

pip install django-cal

Documentation

Overview

Please see Django's syndication feed framework documentation, django_cal imitates its behavior: http://docs.djangoproject.com/en/1.2/ref/contrib/syndication/.

Defining event properties

The following parameters work analagous to how they're implemented in django.contrib.syndication. That means, the framework checks in the following order: self.$param(obj), self.$param(), self.$param; obj being the object returned by self.get_object.

items           Returns the list of events.
                Must be set.
filename        Filename of the file returned in the view.
                Optional, defaults to 'events.ics'.
cal_name        Name of the calendar.
                Optional, defaults to None.
cal_desc        Description of the calendar. 
                Optional, defaults to None.

item_summary    The "title" of the item.
                Optional, defaults to unicode representation of item.

item_end        Duration or end time of item.
item_duration   Optional, defaults to None. Must not define both.

item_rruleset   Optional, defaults to None.
                Should return dateutil.rruleset instance
                for recurrent events.

item_url        Optional, default calls item.get_absolute_url()
                Should return a URL with the fully-qualified domain and
                protocol (e.g. 'http://www.example.com/blog/') or an
                absolute path (e.g. '/events/'). If only a path is
                present, the 'django.contrib.sites' app will be used
                to insert the domain of the current site.
                Note: To find the current site, 'django.contrib.sites'
                      must be in your settings.INSTALLED_APPS (it is
                      there by default)

item_uid        All correspond to their vEvent equivalents.
item_start      All optional, all default to None.
item_description
item_categories
item_comment
item_location
item_last_modified
item_created

Duration of events

django-cal imitates vobject behavior regarding start and end of events. In short: Use Date objects for all-day events, DateTime for more granular control. Define either duration or end time, never both.

Complex behavior

self.get_object can be overriden to allow for more complex events, as is possible for syndication feeds.
