Hi everyone,

I'm trying to domain product_id in sale.order.line based on pricelist in sale.order form.

I'm using a dynamic domain for it but it's not working. Here is my code in sale.order:

@api.onchange('pricelist_id')   

 def onchange_pricelist_id(self):        

product_id = self.order_line.product_id  

product_ids = []        

if self.pricelist_id:            

for rec in self.pricelist_id.item_ids:                

product_ids.append(rec.id)                        

return {'domain': {'product_id': [('id', 'in', product_ids)]}}

I'm also trying to use name_get() in product.product:

def name_get(self):        

if self._context.get('temp'):            

return super(ProductProduct, self).name_get()        

product_list = []        

pricelist = self.env['product.pricelist'].browse(self._context.get('pricelist'))        

if pricelist:            

for rec in pricelist.item_ids:                

if rec.applied_on == '0_product_variant':                    

product_list.append(rec.product_id.id)        

if product_list:            

self = self.browse(product_list)        

result = super(ProductProduct, self).name_get()        

return result

but it throws :

Error:
Odoo Server Error
