我尝试更新 Odoo 代码，但我得到 strptime() 参数 1 必须是 str，而不是布尔值

Question

目标是获取销售日期并创建一个自动访问计划，三年内每年 2 次访问，我可以在旧版本的 odoo 中做到这一点，但现在我收到此错误。

在 Openerp 7 中有效，但现在我想在 Odoo 11.0 Python 3 中做到这一点，真的我不明白我错过了什么

    class garantias(models.Model):
        _name = 'itriplee.garantias'
        equipo = fields.Many2one('itriplee.equipos', 'Equipo')
        fecha_de_venta = fields.Date('Fecha de Venta', related='equipo.venta', readonly=True)
     @api.model
        def create(self, vals):
            obj_visita = self.pool.get('itriplee.servicio')
            obj = self.env['itriplee.garantias']
            cliente = obj.cliente.id
            fecha_compra = obj.fecha_de_venta
            fm = ('%Y-%m-%d')
            cantidad_meses = 6
            ind = 0
            now = datetime.now()
            now_str = now.strftime(fm)
            now_int = datetime.strptime(now_str, fm)
            # fecha_compra_original = datetime.strptime(fecha_compra, fm)
            fecha_compra_inicial = datetime.strptime(fecha_compra, fm)
            while ind < cantidad_meses:
                fecha_6_meses = fecha_compra_inicial + relativedelta(months=6)
                if fecha_6_meses >= now_int:
                    obj_visita.create({'cliente':cliente,'visita':fecha_6_meses,'estado':'confirmar','visitas':obj.id},context=None)
                ind = ind + 1
                fecha_compra_inicial = fecha_6_meses
            return True

并收到此错误：

TypeError: strptime() argument 1 must be str, not bool

Answer 1

当该字段不是日期字符串或包含空值时，会发生此错误，因此在调用时返回 False 值。因此，首先确保在调用函数时该字段包含日期str.strptime方法需要日期字符串值。

您可以使用 if 条件来检查字段继续 strptime 方法中是否存在数据，或者如果您使用的是 pycharm，则可以添加断点来检查值
