Many2Many filter?

[deathrake]

My custom production.py in my custom module

class QualityControlProduction(ModelSQL, ModelView):
    "Quality Control Production"
    __name__ = 'production'    
    inwardno = fields.Many2Many('prod.shipment.relation',
        'prodid','shipid', 'Inward')

class QualityShipmentIn(ModelSQL,ModelView):
    "Quality Shipment In"
    __name__ = "stock.shipment.in"
    inwardid = fields.Many2One('production','Inward ID')
    prodstate = fields.Boolean("In Production")


class ProdShipment(ModelSQL):    
    "Prod Shipment Relation"
    __name__ = "prod.shipment.relation"
    
    shipid = fields.Many2One('stock.shipment.in','Shipment ID',domain=[
            ('state', '=', 'done'),
            ])
    prodid = fields.Many2One('production','Production ID')

i tried domain on shipid in prod.shipment.relation but still it is not applying domain and showing aal the shipments

tried applying domain on many2many filter too like this

class QualityControlProduction(ModelSQL, ModelView):
    "Quality Control Production"
    __name__ = 'production'
    
    inwardno = fields.Many2Many('prod.shipment.relation',
        'prodid','shipid', 'Inward' ,domain=[
            ('shipid.state', '=', 'done'),
            ])

but getting this error

First there is a difference between domain and filter. The domain is a constraint which is checked against all records linked. The filter limits which records are included in the field from the relation table.

Second the domain for a Many2Many is applied directly on the target. So in your example it should be: [('state', '=', 'done')].
