\
\ \ \ \ \ \ \ \ res\.update\(res_inform_ids\=\[\(6\,\ 0\,\ literal_eval\(inform_taking_leave_id\)\)\]\ if\ inform_taking_leave_id\ else\ False\,\ \)\ \ \ \ \ \ \ \
\
\ \ \ \ \ \ \ \ return\ res\
\
\
\
\
\
\ \ \ \ res_inform_ids\ \=\ fields\.Many2many\(\'hr\.employee\'\,string\=\'Inform\ and\ Taking\ Leave\'\,\ help\=\'Inform\ and\ Taking\ Leave\'\,default\=_get_values\,\)\

        inform_taking_leave_id =  with_user.get_param('inform_taking_leave.res_ids')       

        res.update(res_ids=[(6, 0, literal_eval(inform_taking_leave_id))] if inform_taking_leave_id else False, )       

        return res
