I did what you suggested but the calls to:
db.owner.own_end_date.writable = False # not writable
db.owner.own_end_date.readable = False # do not show is at all!
are effective only if executed before the call to form =
SQLFORM.smartgrid(db.owner, ...
When executed after, have no effect.
I want to make db.owner.own_end_date not writeable conditionally:
...
...
if ((len(request.args)>1) and (request.args(1)=='edit')):
if (form.element('input',_name='own_end_date')['_value']!=''):
db.owner.own_end_date.writable=False # <----- no effect
...
...
If the edited record contains a date value in that field then user must not
change it. How can I make that field not writeable in such a case?
Thanks
