Hello all,
I'm writing a web app where people can log their exercise sessions.
Basically, sessions are timed, and the faster the better. To this end, I
store seconds in my model:
Field('f_record_taken', type='date',notnull=True,default=datetime.date.
today(),
label=T('Record Taken')),
Field('f_user', type='reference auth_user',notnull=True,
label=T('User')),
Field('f_exercise', type='reference t_exercise_description',notnull=True
,
label=T('Exercise')),
### either repetitions, time or weight
Field('f_measure', type='double',notnull=True,
label=T('Measurement')),
Field('f_comment', type='string',label=T("Comment")),
I use SQLForm to let users insert new entries:
form = SQLFORM(db.t_exercise_log, fields = ["f_record_taken", "f_measure",
"f_comment"]
Obviously, this will render the f_measure field as a single form entry -
but users do not want to enter seconds because it requires them to do the
math from minutes to seconds. I could theoretically use a time field
instead, but I use the f_measure field for other types of exercise as well
(think "weight lifted in kilos").
How would you go about doing this? I assume I could use SQLForm.Factory,
but then I might have to validate the form by hand (?). So I'm wondering
what would be the best, most web2py-ish solution here, e.g. by modifying
some kind of representation logic in the model.
Kind regards,
Michael
