====================================
User tracking in the loops framework
====================================
($Id$)
>>> from cybertools.tracking.btree import TrackingStorage
>>> tracks = TrackingStorage()
>>> tracks.saveUserTrack('a001', 0, 'u1', {'somekey': 'somevalue'})
'0000001'
>>> t1 = tracks.getUserTracks('a001', 0, 'u1')
>>> len(t1)
1
>>> t1[0].data
{'somekey': 'somevalue'}
>>> tracks.getUserNames('a001')
['u1']
>>> tracks.getUserNames('a002')
[]
>>> [str(id) for id in tracks.getTaskIds()]
['a001']
>>> tracks.query(taskId='a001')
[<Track ['a001', 1, 'u1', '...-...-... ...:...']: {'somekey': 'somevalue'}>]
>>> tracks.saveUserTrack('a002', 0, 'u1', {'somekey': 'anothervalue'})
'0000002'
>>> result = tracks.query(userName='u1')
>>> len(result)
2
What happens if we store more than on record for one set of keys?
>>> tracks.saveUserTrack('a001', 0, 'u1', {'somekey': 'newvalue'})
'0000003'
>>> t2 = tracks.getUserTracks('a001', 0, 'u1')
>>> [t.data for t in t2]
[{'somekey': 'somevalue'}, {'somekey': 'newvalue'}]
The tracks of a tracking store may be reindexed:
>>> tracks.reindexTracks()
Fin de partie
