Question

如何计算我的例子中的小时数：

（（完成 - 开始） - 暂停）

表单视图中的

格式

start = 02/10/2017 07:55:54

finish = 02/10/2017 16:50:54

暂停= 1小时（默认）

在控制台日期时间

看起来像这样：2017-02-10 07:55:54

需要这个==＆gt;结果= 07:55

How in @api.depends('start', 'finish') 
    def calculate_hours(self):
        #

Answer 1

您可以使用timedelta或相对delta来计算差异。在此之前，您必须转换为datetime对象。这就是我要做的事情

from openerp import api, fields
# if use relativedelta 
from dateutil.relativedelta import relativedelta 


@api.depends('start', 'finish')
def calculate_hours(self):
  for record in self:
    start_dt = fields.Datetime.from_string(record.start)
    finish_dt = fields.Datetime.from_string(record.finish)

    # using relativedelta 
    # pause time = 1, you could change to the number you desire. 
    pause = relativedelta(hours=1)
    difference = relativedelta(finish_dt, start_dt) - pause 
    # from relative delta you could get hours or minutes as you wanted 
    # hours = difference.hours 
    # minutes = difference.minutes 

    # using timedelta 
    # pause = timedelta(seconds=3600)
    # difference = finish_dt - start_dt - pause
    # first element of timedelta is days, if you want to calculate the difference of days in hours, add difference.days * 24  
    # hours = int(difference.seconds/3600)
    # minutes = (difference.seconds % 3600) / 60
    # your code ....

希望我的回答符合您的要求。
