Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
class SoftOneInvoice(models.Model):
_inherit= "account.move"
global_discount=fields.Float('global discount')
class SoftOneInvoiceLine(models.Model):
_inherit= "account.move.line" @api.onchange("discount")
def _onchange_discount(self):
self.move_id.global_discount=0.0
The code above doesn't update in form view the custom field global_discount of account.move model when I change the discount field of an account move line.
Try to use the write method as below:
self.move_id.write({'global_discount':0.0})
Tried with both .write and .update methods without success.
You can do it by override write method as below and you can add your conditions if you want to check the value of discount by using vals.get('discount') :
def write(self, vals):
res = super(SoftOneInvoiceLine, self).write(vals)
if 'discount' in vals:
self.move_id.global_discount=0.0
return res
