Hi all!, could somebody get me a hand in order to improve this code, please?
I'm getting a array of dicts here, every device have it last event attached
in the dict...
I'm want delete the iteration over the events table, I don't think it is
efficient enough
maybe it could be changed doing a better query, joining the event and
device tables in a sql view...
on this way I can get a row.as_dict directly....
db.define_table('devices',
Field('serial'),
Field('brand'),
Field('location'),
format='%(serial)s'
)
db.define_table('events',
Field('device_id'),
Field('date', datetime),
Field('location'),
format='%(device_id)s'
)
@service.json
events_service():
events = {}
devices = db(db.devices).select()
for dev in devices:
event = db(db.events.device_id == dev.id).select().last()
events[dev.id] = {
'name':event('name'),
'date':event('date'),
'brand':dev.brand,
'location':dev.location }
return events
Thanks in advance.
Christian.
