Hello everyone,

To explain the context, I created a custom module with a model that inherits from stock.scrap. This model automatically creates a barcode for scrap when it is created. Here's the code:

from odoo import models, fields, api

class StockScrapInherit(models.Model):    
   _inherit = ['stock.scrap']
   barcode = fields.Char(string='Code-barres')

   @api.model
   def create(self, vals):
      # Get the last barcode. If null, create the default one
      last_scrap = self.env['stock.scrap'].search([], order='barcode desc', limit=1)                
      last_barcode = last_scrap.barcode if last_scrap else 'SCRAP-A0000'

      if not isinstance(last_barcode, str):
         last_barcode = 'SCRAP-A0000'

      last_letter = last_barcode[6]
      last_number = int(last_barcode[7:])

      if last_number          new_number = last_number + 1
         new_barcode = 'SCRAP-' + last_letter + str(new_number).zfill(4)        
      else:            
            new_letter = chr(ord(last_letter) + 1)
            new_barcode = 'SCRAP-' + new_letter + '0001'

      vals['barcode'] = new_barcode
      
      record = super(StockScrapInherit, self).create(vals)
      return record

However, I can't manage to inherit the Barcode module that would allow me to redirect to the scrap page when its barcode is scanned. 

Do you have any idea how to do this?

Thanks in advance!
