I have a `One2Many` field which has some products and I want to get the "Cost" of these products. I don't have much time which I started in odoo and this is mid difficult for me yet to achieve. Can someone help me?

At the moment what I have only done is this:

class ComboProductTemplate(models.Model):
    _inherit = "product.template"



    is_combo = fields.Boolean('Combo Product', default=False)
    combo_product_id = fields.One2many('product.combo', 'product_template_id', 'Combo Item')
    product_cost_id = fields.Many2one("product.product", 'standard_price')
    combo_price = fields.Float("Combo Price: ", compute='_compute_combo_price')

    def _compute_combo_price(self):
        products = self.env['product.product'].search([('standard_price', '=', self.standard_price)])
        for ids in products:
            print(ids.ids)
        unique_variants = self.filtered(lambda template: len(template.product_variant_ids) == 1)
        print(unique_variants)
        for template in unique_variants:
            print(f"TEMPLATE: {template}")
            template.standard_price = template.product_variant_ids.standard_price
            print(template.standard_price)
        for template in (self - unique_variants):
            print("here")
            template.standard_price = 0.0

The computed function will get the `standard_price` of current product I click.

What I except:

Get the products on `one2many` field and get each one of them `standard_price`.

What am I getting?

At the moment I'm only getting the only one product `standard_price`
