Question

我想要从excel导入数据到自定义模块。我在excel中有开始和结束（datetime）是否可以在导入数据后定义字段总数（完成 - 开始）以获得结果？

例如：

class time(models.Model):
    _name = "time"
    _description = "Time"

    start = fields.Datetime(string = 'Start', placeholder="Start") 
    finish = fields.Datetime(string='Finish', placeholder="Finish")


    total = fields.Float(string='Total minutes', placeholder="Total")


_defaults = {

                 'total': (finish - start)
   }

Answer 1

您必须添加start和finish的onchange方法来计算total。

实施例

@api.onchange('start', 'finish')
def onchange_start_finish(self):
    for time in self:
        time.total = time.finish - time.start

其他方式，

如果您将计算字段视为total.like，

total = fields.Float(compute='_methods_total', string='Total minutes', placeholder="Total")

@api.depends('start', 'finish')
def _methods_total(self):
    for time in self:
        time.total = time.finish - time.start

插入数据后自动填充字段
