I'm trying to overwrite Orderline price in POS Odoo
**My price.js**
get_unit_display_price: function(){
var self = this;
var line = self.export_as_JSON();
var product = this.pos.db.get_product_by_id(line.product_id);
fields.product_id = line.product_id;
fields.pricelist_id = this.pos.config.pricelist_id[0];
fields.uom = product.uom_id;
fields.line_qty = line.qty;
fields.price_unit = line.price_unit;
var model = new Model('pos.order');
this.total_price = model.call('calculate_price',
[0, fields]).done(function(result){
total_price = result['total_price'];
return result['total_price'];
});
}
**price.xml**
<t t-jquery=".price" t-operation="append">
<t t-esc="widget.format_currency(line.get_unit_display_price)"/>
</t>
I'm getting value **total_price** from Model (price.py)
But returning is **undefined** in get_unit_display_price in xml file.
How to set value in xml from js after execution of new model function (js value from model) ?.
