A generic SCORM API
|
|
===================
|
|

($Id$)
|
|
|
|
In order to work with the SCORM API we first need a tracking storage.
|
|
|
|
>>> from cybertools.tracking.btree import TrackingStorage
|
|
>>> tracks = TrackingStorage()
|
|
|
|
We can now create a ScormAPI adapter. Note that this adapter is stateless
|
|
as it is usually created anew upon each request.
|
|
|
|
>>> from cybertools.scorm.base import ScormAPI
|
|
>>> api = ScormAPI(tracks, 'a001', 0, 'user1')
|
|
|
|
The first step is always the initialize() call - though in our case it
|
|
does not do anything.
|
|
|
|
>>> api.initialize()
|
|
'0'
|
|
|
|
Then we can set some values.
|
|
|
|
>>> rc = api.setValue('cmi.interactions.0.id', 'q007')
|
|
>>> rc = api.setValue('cmi.interactions.0.result', 'correct')
|
|
>>> rc = api.setValue('cmi.comments_from_learner', 'Hello SCORM')
|
|
>>> rc = api.setValue('cmi.interactions.1.id', 'q009')
|
|
>>> rc = api.setValue('cmi.interactions.1.result', 'incorrect')
|
|
|
|
Depending on the data elements the values entered are kept together in
|
|
one track or stored in separate track objects. So there is a separate
|
|
track for each interaction and one track for all the other elements.
|
|
|
|
>>> for t in sorted(tracks.values(), key=lambda x: x.timeStamp):
|
|
... print t.data
|
|
{'id': 'q007', 'key_prefix': 'cmi.interactions.0', 'result': 'correct'}
|
|
{'cmi.comments_from_learner': 'Hello SCORM', 'key_prefix': ''}
|
|
{'id': 'q009', 'key_prefix': 'cmi.interactions.1', 'result': 'incorrect'}
|
|
|
|
Using the getValue() method we can retrieve certain values without having
|
|
to care about the storage in different track objects.
|
|
|
|
>>> api.getValue('cmi.comments_from_learner')
|
|
('Hello SCORM', '0')
|
|
>>> api.getValue('cmi.interactions.0.id')
|
|
('q007', '0')
|
|
>>> api.getValue('cmi.interactions.1.result')
|
|
('incorrect', '0')
