Had to revert this
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))
to this
elif request.post_vars.modified_on != str(db.client(request.vars.id).
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))
because if the record was changed by another user while the this user was
editing and the this user made a mistake in a field that was auto-checked
by web2py (using the requires from the model file), the upper version would
not catch that the record had been changed and would save the record
instead of showing the message.
Per your suggestion, I have this in the index function (where the grid is
created):
if 'edit' in request.args:
form = grid.update_form
form['hidden'].update(modified_on=form.record.modified_on)
