Goal is to compute bottleneck_delay_time in hours by subtracting
request.now from created_on date.
What is correct syntaxt?
Below is wrong but shows intent.
MODEL
db.define_table('InternalMessage',
Field('bottleneck_resolve_date', 'datetime', default = None),
Field('bottleneck_delay_time', 'integer', label = 'Bottleneck Delay
Time In hours'))
CONTROLLER
from datetime import timedelta
db(db.InternalMessage.bottleneck_resolve_date ==
None).update(bottleneck_delay_time = (timedelta(request.now) -
timedelta(db.InternalMessage.created_on)))
thanks
Alex Glaros
