Hello All,

I try to applied domain for many2one type field. But i find following Error:

TypeError: district.district(11,) is not JSON serializable

My Onchange function code is here:

@api.onchange('district_table_case')

    def _onchange_district_table(self):

        print "A:", self.district_table_case.district_mainn

        print "B:", self.district_table_case.district_ss

        #print "C:", self.district_table_case.district_ss.district

        rec = self.district_table_case.district_ss

        res = self.district_table_case.district_mainn

        print "res:", res

        for vals in rec:

            print "C:", vals

            print "D:", vals.district

            if vals.district:

                return {'domain': {'district_table': [('id', 'in', vals)]}}

            else:

                return {'domain': {'district_table': []}}

district_table_case = fields.Many2one('district.districe.code', change_default=True, default=_onchange_district_table)
