Made the changes you suggested. Thanks Anthony.
This is an example of my new onvalidation, just in case you have other tips
:)
def on_validation(form: SQLFORM) -> None:
"""Used in the edit form, including when creating and deleting.
:param form: Form.
"""
# Fix for SQLite instead of for_update=True. When for_update is
# fixed for SQLite, only the first SELECT in the function should
# have for_update=True.
while True:
try:
# SQLite only does database lock.
db.executesql('BEGIN IMMEDIATE TRANSACTION')
break
except sqlite3.OperationalError:
sleep(0.5)
if request.args and request.args[0] == 'new':
if db.wo_counter(year_=request.now.year):
form.errors.last_assigned = T('Counter already exists')
else: # Edit/delete.
if (not form.record.is_active and not form.vars.delete_this_record
and auth.has_membership(SUPERVISOR_ROLE)):
db.wo_counter(request.vars.id).update_record(
cancel_approved_by=None,
canceled_by=None,
canceled_on=None,
is_active=True,
)
db.commit()
session.flash = T('Record was activated.')
redirect(URL('index', user_signature=True))
elif not form.record.is_active:
session.flash = T('Record was deleted while you were editing.')
redirect(URL('index', user_signature=True))
elif (request.post_vars.modified_on != str(form.record.modified_on
)):
session.flash = T('Record was changed while you were editing. '
'This is the updated record.')
redirect(URL(args=request.args, vars=request.get_vars,
user_signature=True))
elif db.wo_counter(request.args[-1]).last_assigned > form.vars.
last_assigned:
form.errors.last_assigned = T('New value must >= than old.')
elif form.vars.delete_this_record:
db.wo_counter(request.vars.id).update_record(
cancel_approved_by=auth.user_id,
canceled_by=auth.user_id,
canceled_on=request.now,
is_active=False,
)
db.commit()
session.flash = T('Done.')
redirect(URL(user_signature=True))
