Django - serving an ical file - django

Question

I'm server an icalender file through django_ical. Problem is that the file is named download.ics. I'm trying to change this to MyCalender.ics. If found this old snippet. I would prefer using django_ical, because it ingerates nicely with django syndication.
cal = vobject.iCalendar()
cal.add('method').value = 'PUBLISH' # IE/Outlook needs this
for event in event_list:
vevent = cal.add('vevent')
icalstream = cal.serialize()
response = HttpResponse(icalstream, mimetype='text/calendar')
response['Filename'] = 'filename.ics' # IE needs this
response['Content-Disposition'] = 'attachment; filename=filename.ics'

Answer 1

In django_ical the ICalFeed is inherited from django.contrib.syndication.views.Feed
In your app you inherit from ICalFeed to provide items, item_title and other methods that generate data for ics file.
You can override the __call__ method. The call to super will return you HttpResponse and you will add custom headers to it.
The code will be something like:
class EventFeed(ICalFeed):
"""
A simple event calender
"""
product_id = '-//example.com//Example//EN'
timezone = 'UTC'
def items(self):
return Event.objects.all().order_by('-start_datetime')
# your other fields
def __call__(self, request, *args, **kwargs):
response = super(EventFeed, self).__call__(request, *args, **kwargs)
if response.mimetype == 'text/calendar':
response['Filename'] = 'filename.ics' # IE needs this
response['Content-Disposition'] = 'attachment; filename=filename.ics'
return response
This code is not tested, so there might be some typos. Also you need to catch if there were errors in call to super. I do it by response.mimetype == 'text/calendar' but maybe there is a better way to do it
