I share with you a solution that gives leonel camara to a problem that I
encounter
my question :
users must score the hours or minutes of work performed on the project.
it's for Timesheet software. obligation: the data must be store in database
, so virtual field impossible.
the solution was give by leonel camara (thanks lot!!)
one thing you can do is store the time in the database as an integer
representing minutes or seconds if you need that much resolution the user
can input hours minutes etc and you convert it to a single number in
minutes.
from gluon.validators import Validator, translate, regex_time
class IS_SECONDS(Validator):
def __init__(self, error_message='Enter time as hh:mm:ss'):
self.error_message = error_message
def __call__(self, value):
try:
ivalue = value
value = regex_time.match(value.lower())
(h, m, s) = (int(value.group('h')), 0, 0)
if not value.group('m') is None:
m = int(value.group('m'))
if not value.group('s') is None:
s = int(value.group('s'))
return (h*3600 + m*60 + s, None)
except AttributeError:
pass
except ValueError:
pass
return (ivalue, translate(self.error_message))
db.define_table('planing',
Field('seconds_worked', 'integer', widget=SQLFORM.widgets.time.widget,
requires=IS_SECONDS(), label=T('Time Worked')),
Field('seconds_holidays', 'integer',
widget=SQLFORM.widgets.time.widget, requires=IS_SECONDS(), label=T('Time
Holidays')),
Field('seconds_total', 'integer', writable=False, compute=lambda row:
row.seconds_worked + row.seconds_holidays)
)
