Invalid View Definition - Odoo V9 Community

I manage to find a way to have the product price on stock.picking, but now I have a view error. This is my model: from openerp import models, fields, api import openerp.addons.dec

Solution 1:

You are adding price_unity field in view inside pack_operation_product_ids field.

pack_operation_product_ids is a One2many relation type with stock_pack_operation object.

So we need to add/register price_unity field in stock_pack_operation object.

Try with following code:

class StockPackOperation(models.Model):
    _inherit = 'stock.pack.operation'

    price_unity = fields.Float(string="Precio", store=True, readonly=True, related="product_id.lst_price")

    #product_id is already in table so no need to add/register

Afterwards restart Odoo server and upgrade your custom module.

NOTE:

You are not getting error in tree of Stock Picking because you have added/registered price_unity.

Your view code is good.
