Hello,
i have a Problem with domains on a fields.Reference:
I want to restrict the value of a Many2One field depending on a
fields.Reference in the target.
The target is a stock.lot that i extended with a field.Reference called
'origin'.
Now i want to restrict the lots in a M2O-field in another Model to a
certain lot.origin.
One try was giving the value of the Reverence as a tuple:
supplier_lot = fields.Many2One('stock.lot', 'Supplier Lot',
domain=[ ('origin', '=',
('party.party', Eval('context', {}).get('supplier', -1))
),
('product', '=', Eval('product'))
])
This way it works fine when creating:
- only the right Lots are sugested in the search
- creating new lots the origin fields are filled with the right values
- the new lot is saved to all right with the right origin
but when i want to save the record with the field 'supplier_lot'
containing the domain, i get a popup stating that i cant save because of
a domain mismach in this field. Did i miss anything here, or is this a
bug? Unfortunaltelly i was not able to spot the very place this domain
is validated and fails.
The other try was using a fouth parameter in the domain with even worse
result:
supplier_lot = fields.Many2One('stock.lot', 'Supplier Lot',
domain=[ ('origin', '=',
Eval('context', {}).get('supplier', -1),
'party.party'
),
('product', '=', Eval('product'))
])
This four parameter version may seem "worse" but it is closer to the
correct answer.
You need to compare on origin.id not just origin:
domain=[ ('origin.id', '=',
Eval(...
See if that works for you.
this way i get an Error in the Server when i start typing in the
'supplier_lot'-field, when it is trying to find sugestions:

thanks for any help...
