如何计算数目小时9

Question

如何计算在我的例子小时：

（（FINISH - START） - 暂停）在窗体视图

格式

开始= 02 /二千〇十七分之十7点55分54秒

光洁度= 2017年2月10日十六点50分54秒

暂停= 1小时（默认）

---

在控制台的日期时间是这样的：2017年2月10日7点55分54秒

需要此==>结果= 07:55

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

Answer 1

你可以使用timedelta或相对增量来计算差异。在此之前，你必须转换为日期时间对象。下面是我会怎么做

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 .... 

希望我的回答能满足您的要求。
