Attendee

This document will describe some manipulations possible for attendees that participate in events.

First, let's create an event storage:

>>> from calcore import cal
>>> m = cal.StorageManager()
>>> m.setStorage(cal.MemoryStorage('storage'))

Now let's create some attendees:

>>> s = cal.SimpleAttendeeSource(m)
>>> martijn = s.createIndividual('martijn', 'Martijn')
>>> lennart = s.createIndividual('lennart', 'Lennart')

Martijn creates an event:

>>> from datetime import datetime, timedelta
>>> event = martijn.createEvent(
...   dtstart=datetime(2005, 2, 10, 14, 00),
...   duration=timedelta(minutes=60),
...   title='An event')

Martijn initially is a REQ-PARTICIPANT:

>>> event.getParticipationRole(martijn)
'REQ-PARTICIPANT'

He's in the list of attendees:

>>> event.getAttendeeIds()
['martijn']

He's a REQ-PARTICIPANT, so he's in that list too:

>>> event.getAttendeeIds(participation_role='REQ-PARTICIPANT')
['martijn']

He's also ACCEPTED, as he's the organizer:

>>> event.getAttendeeIds(participation_status='ACCEPTED')
['martijn']

Lennart isn't participating at all yet:

>>> repr(event.getParticipationRole(lennart))
'None'

Martijn now is declared the chair of this event:

>>> event.setParticipationRole(martijn, 'CHAIR')
>>> event.getParticipationRole(martijn)
'CHAIR'
>>> event.getAttendeeIds(participation_role='REQ-PARTICIPANT')
[]
>>> event.getAttendeeIds(participation_role='CHAIR')
['martijn']

Lennart is invited:

>>> event.invite([lennart])
>>> event.getParticipationRole(lennart)
'REQ-PARTICIPANT'
>>> attendee_ids = event.getAttendeeIds()
>>> attendee_ids.sort()
>>> attendee_ids
['lennart', 'martijn']
>>> event.getAttendeeIds(participation_role='REQ-PARTICIPANT')
['lennart']

We'll remove Lennart again by setting his participation status to None:

>>> event.setParticipationStatus(lennart, None)
>>> event.hasAttendee(lennart)
False
>>> repr(event.getParticipationStatus(lennart))
'None'
>>> repr(event.getParticipationRole(lennart))
'None'
>>> event.getAttendeeIds()
['martijn']

Regression tests:

• XXX - should be in test_cal

• cal.AttendeeBase objects should implement interfaces.IAttendee:

  >>> from zope.interface.verify import verifyObject
  >>> from calcore import interfaces
  >>> dino = cal.AttendeeBase('a', 'b', 'c', 'd')
  >>> verifyObject(interfaces.IAttendee, dino)
  True
  

• as should cal.Attendee objects:

  >>> verifyObject(interfaces.IAttendee, martijn)
  True
