I have a 2 models:

class DiscountLineMixin(models.AbstractModel):

    _name = "discount.line.mixin"
    _description = "Discount Line Mixin"

    product_discountlist_ids = fields.One2many(
        comodel_name="discountlist.percent",
        inverse_name="order_line_id",
        string="Product discountlist item effective_percent",
    )

and

class ProductDiscountPercent(models.Model):

    _name = "discountlist.percent"
    _description = "Discountlist rules discountlist per order line"

    model_name = fields.Char()
    record_id = fields.Integer()
    order_line_id = fields.Reference(
        selection="_select_target_model",
        string="Order Line",
    )
    discountlist_item_id = fields.Many2one(
        comodel_name="product.discountlist.item",
        string="Discountlist item",
    )
    effective_percent = fields.Float(
        "Effective Percentage Price",
    )

    @api.model
    def _select_target_model(self):
        models = self.env["ir.model"].search([])
        return [(model.model, model.name) for model in models]

    @api.model
    def create(self, vals):
        if "model_name" in vals and "record_id" in vals:
            vals["order_line_id"] = f"{vals['model_name']},{vals['record_id']}"
        return super(ProductDiscountPercent, self).create(
            vals
        )

    def write(self, vals):
        if "model_name" in vals or "record_id" in vals:
            for record in self:
                model_name = vals.get("model_name", record.model_name)
                record_id = vals.get("record_id", record.record_id)
                vals["order_line_id"] = f"{model_name},{record_id}"
        return super(ProductDiscountPercent, self).write(vals)

I wanna create a one2many relation from Abstract model to normal model.
But when i create a record from AbstractModel by:

new_values = [
                    (0, 0, {
                        "model_name": self._name,
                        "record_id": self.id,
                        "discountlist_item_id": discountlist_item.id,
                        "effective_percent": effective_discount,
                    }),
                ]
                self.write({"product_discountlist_ids": new_values})

or

discountlist_item_percent = self.env["discountlist.percent"].create({
    "model_name": self._name,
    "record_id": self.id,
    "discountlist_item_id": discountlist_item.id,
    "effective_percent": effective_discount
})
self.product_discountlist_ids = [(4, discountlist_item_percent.id)]  

in both cases i have a created discountlist_item_percent record but adding reference to product_discountlist_ids not work.

In debugger i have:

self.product_discountlist_ids = discountlist.percent()
discountlist_item_percent = discountlist.percent(284,)

I assume that the problem is with using field.Reference for inverse_name in One2Many, but not sure how to fix this to work. I need to have Reference because this abstract model is used in many other models.
