Hello, I have a module with this code in stock.picking

# models/stock_picking.py
from odoo import fields, models, api

class StockPicking(models.Model):
    _inherit = 'stock.picking'

    invoice_status = fields.Boolean(string='Invoice Status', default=False)

    @api.depends('sale_id.invoice_ids')
    def _compute_invoice_status(self):
        for picking in self:
            invoices = picking.sale_id.invoice_ids.filtered(lambda inv: inv.state != 'cancel')
            picking.invoice_status = bool(invoices)
and this is the xml

    
        stock.picking.form.inherit
        stock.picking
        
        
            
                
            
        
    

If I create a sales order, and confirm it but do not create its corresponding invoice, I want the boolean field to remain False, but if an invoice is created for the sales order, I want it to go to True automatically... .

I tried with that code and some others and it didn't work, can you guide me?

Thanks and sorry for bothering.
