Change the domain of a many2one field depending on other field value

Question

Hi;
i have a selection field called receiving_type with 3 options: cash, credit card and check
and another Many2one field called journal_id that shows the journals
the journal has 3 Boolean fields: check, credit_card, cash
i want to change the domain of journal_id depending on the value of the receiving type
for example:
journal x is cash journal, journal y is not
when i choose cash as receive type, i should see journal x only :)
Thanx!

Hi Bro,
This is your solution :
@api.onchange('receiving_type')
*def* onchange_receiving_type(self):
b*=*{}
*if* self.receiving_type*=**=*'cash':
b *=*{'domain': {'journal_id': [('cash', '=', 1)]}}
*if* self.receiving_type*=**=*''credit_card':
b *=*{'domain': {'journal_id': [('credit_card', '=', 1)]}}
*if* self.receiving_type*=**=*'check':
b *=*{'domain': {'journal_id': [('check', '=', 1)]}}
*return* b
Dont forget to * vote positif * :).

Hi,
See this sample, in this we have two fields one is partner_id and other is order_id , then if you choose a partner in partner_id field, then domain is given for the other field based on this.

partner_id = fields.Many2one('res.partner', string="Customer")
order_id = fields.Many2one('sale.order', string="Sale Order")
@api.onchange('partner_id')
def onchange_partner_id(self):
for rec in self:
return {'domain': {'order_id': [('partner_id', '=', rec.partner_id.id)]}} See this:-  How To Give Doma
