Odoo 17中_post方法soft参数缺失报错问题求助

在Odoo 17中扩展AccountMove模型的_post方法，开发阶段测试正常，但部署到新数据库后，执行采购收货操作时触发报错。报错提示调用AccountMove._post()缺少必填参数soft，但自身代码调用该方法时已传递该参数，且未继承采购相关模块，无法理解报错原因。

自定义实现代码 #

def _post(self, soft):
    facturas_especiales = self.filtered(lambda factura: factura.factura_especial)
    for factura_especial in facturas_especiales:
        if not factura_especial.journal_id.facturas_especiales:
            raise ValidationError("El diario no está configurado para trabajar con facturas especiales")

move_types = ["fact", "fact_cambiaria", "fact_exportacion", "out_refund"]
por_certificar = self.filtered(
    lambda factura: factura.journal_id.facturacion_activa
    and (factura.tipo_factura in move_types or factura.factura_especial or not factura.tipo_factura)
    and not factura.certificada
)

for factura in por_certificar:
    if self.company_id.proveedor == "infile":
        infile.facturacion_electronica(self, factura)
    elif self.company_id.proveedor == "cofidi":
        cofidi.facturacion_electronica(self, factura)

continuar_movimientos = self.filtered(lambda fact: not fact.certificacion_error)
return super(AccountMove, continuar_movimientos)._post(soft)

核心原因 #

Odoo 17原生的AccountMove._post方法中，soft是可选参数，默认值为False，定义如下：

def _post(self, soft=False):
    # 原生逻辑

但你重写方法时，将soft设为了必填位置参数（没有默认值），而其他模块（如stock_account）调用_post()时未传递该参数，导致触发TypeError。

修复步骤 #

1. 修改_post方法参数定义，给soft加上默认值，与原生方法保持一致：

def _post(self, soft=False):  # 添加默认值False
    facturas_especiales = self.filtered(lambda factura: factura.factura_especial)
    for factura_especial in facturas_especiales:
        if not factura_especial.journal_id.facturas_especiales:
            raise ValidationError("El diario no está configurado para trabajar con facturas especiales")

    move_types = ["fact", "fact_cambiaria", "fact_exportacion", "out_refund"]
    por_certificar = self.filtered(
        lambda factura: factura.journal_id.facturacion_activa
        and (factura.tipo_factura in move_types or factura.factura_especial or not factura.tipo_factura)
        and not factura.certificada
    )

    for factura in por_certificar:
        # 优化：原代码用self.company_id存在多公司风险，改为factura.company_id
        if factura.company_id.proveedor == "infile":
            infile.facturacion_electronica(self, factura)
        elif factura.company_id.proveedor == "cofidi":
            cofidi.facturacion_electronica(self, factura)

    continuar_movimientos = self.filtered(lambda fact: not fact.certificacion_error)
    return super(AccountMove, continuar_movimientos)._post(soft)

2. 额外优化点：原代码中self.company_id存在风险，因为self是AccountMove的记录集，可能包含多个公司的凭证，改为factura.company_id可避免多公司场景下的逻辑错误。

验证 #

修改后重新升级模块，执行采购收货操作，报错即可解决。
