Development

Replace this code:

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

    net_weight = fields.Float(
        compute="_compute_net_weight",
        inverse="_inverse_net_weight",
        store=True,
    )

    @api.depends("product_variant_ids", "product_variant_ids.net_weight")
    def _compute_net_weight(self):
        for template in self:
            if template.product_variant_count == 1:
                template.net_weight = template.product_variant_ids.net_weight
            else:
                template.net_weight = 0.0

    def _inverse_net_weight(self):
        for template in self:
            if len(template.product_variant_ids) == 1:
                template.product_variant_ids.net_weight = template.net_weight

  def _get_related_fields_variant_template(self):
      res = super()._get_related_fields_variant_template()
      res.append("net_weight")
      return res

By this code:

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

    net_weight = fields.Float(
        compute=lambda x: x._compute_template_field_from_variant_field("net_weight"),
        inverse=lambda x: x._set_product_variant_field("net_weight"),
        store=True,
    )

  def _get_related_fields_variant_template(self):
      res = super()._get_related_fields_variant_template()
      res.append("net_weight")
      return res

Known issues / Roadmap

Do not port this module in version 17.0.

(the feature is native since V17.0)
