Hi,
The above prompt error is from the ff code:
from odoo.exceptions import UserError, ValidationError
class AccountPayment(models.Model):
_inherit = "account.payment"
# readonly=True,
check_number_char = fields.Char(string="Check Number")
@api.one
@api.one
@api.constrains('check_number_char')
def isNumeric_check_number(self):
if not self.check_number_char.isdigit():
raise ValidationError(_("A check number must be numeric."))
