Hello,

I added a field into product.template model called "pieces_inside_1_cartoon" and I want this field to appear into the tree of stock.view_picking_form, so when the user chooses a product, the pieces_inside_1_cartoon appears.
I keep getting errors concerning that matter.

------------------------------------------------

Here is the product.template model I inderited:

from odoo import models, fields, api


class StockPicking(models.Model):
_inherit = 'stock.picking'

product_id = fields.Many2one("product.template")
pcs_per_cartoon = fields.Integer(related="product_id.pcs_per_cartoon", string="Number of cartons")
# pcs_per_cartoon = fields.Integer(string="Number of cartons")

--------------------------------------------------------

Here is the view I inherited:



view.picking.form.inherited
stock.picking

1001




position="after">

-----------------------------------------------

Here is the error I keep getting:

Field "pcs_per_cartoon" does not exist in model "stock.move"
