Hi the scenario is like this .

I have a record and that recoed is editable in all states except approved .

I have three groups.

group_A, group_B, group_C and group A and B can edit it in draft and new states . and group C can edit it once the record is in approved state.

'timesheet_ot_ids' : fields.one2many('timesheet.ot.line', 'sheet_otid',
            'Timesheet OT lines',
            readonly=True, states={
                'draft': [('readonly', False)],
                'new': [('readonly', False)]}
            ),

and i need to make it editable for users from a particular group even though the state is approved .

Appreciate your help .

Thanks.
