Create a field with total value of the invoice in stock using the origin to pull right

Question

I want to bring the total value of the invoice to the stock.picking using the origin to bring it right
I tried to do something else, it did not work
can you help me?
from odoo import api, fields, models, _ from odoo.exceptions import UserError

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

def get_x_total(self):
current_total = self.env['account.invoice'].search([('origin','=',self.origin)])
x_total = current_total.('account.invoice').amount_total

return x_total

x_amout_total

Origin its a charlar field. Its editable so its bot the best option to make a search.
I would set a compute field, instead of default. But anyways I think its not working because of this line:
x_total = current_total.('account.invoice').amount_total
Try:
x_total = current_total.amount_total

Consegui usando o seguinte cod
class StockPicking(models.Model):
_inherit = 'stock.picking'

'''FUNCAO PARA PEGAR DENTRO DO ACCOUNT.INVOICE O VALOR TOTAL DA FATURA E JOGAR DENTRO DA VARIAVEL X_AMOUNT_TOTAL
(FUNCAO USADA PARA PODER COLOCAR VALOR DA FATURA DENTRO DO RELATORIO DE NOTA DE ENTREGA'''
@api.one
@api.depends('priority')
def get_x_total(self):
invoice = self.env['account.invoice'].search([('origin','=',self.origin)])
x_total_valor = sum(line.amount_total for line in invoice)
self.x_amoun
