how prduct and sale price are mapped to sale_order_line in sales module

Question

I have added some fields in product.template. I need to display the field in sale_order_line in sales module. How can I make it possible?

Hi,
You can write a *onchang*e function for the product field in the order line. In the onchange function write the value to new field or you can make the new field as *related* field.
@ api.onchange ( 'product_id' )
def  function_name ( self ):
if  self .product_id:
self .new_field_name = self .product_id.field_in_product Thanks

Hi Sarina,
You can change price_unit field to a functional field.
@api.one
@api.depends('mrp', 'discount')
def _compute_price_unit(self)
self.price_unit =  self.mrp - self.discount
price_unit = fields.Float('Unit Price', compute='_compute_price_unit', store=True)
If you don't want to store the value in database, then you can use this:
@api.one
def _compute_price_unit(self)
self.price_unit =  self.mrp - self.discount
price_unit = fields.Float('Unit Price', compute='_compute_price_unit')

Can I calculate price_unit in sale_order line if I put a new field in sale order line like
price_unit=mrp-discount
