我正在使用odoo版本8中的酒店管理模块。
我希望计算入住日期和退房日期之间的住宿天数。谁能帮我这个？
我为预订定义了一个类，其中包含用于签入和签出的更改方法。我尝试了计算total_nights的函数。这是我的代码，

此代码可以帮助您：
# Making difference in dates to get no. of days .....
@api.one
@api.onchange('check_in')
def onchange_date_time(self):
# print 'working till now ----------------------------'
if self.check_in:
check_in = datetime.datetime.strptime(self.check_in, "%Y-%m-%d").date()
if check_in<datetime.date.today():
#raise except_orm('Error','Please enter the correct date')
self.check_in = None
else:
pass
@api.one
@api.onchange('check_out')
def onchange_check_out(self):
if self.check_out:
check_out = datetime.datetime.strptime(self.check_out, "%Y-%m-%d").date()
check_in = datetime.datetime.strptime(self.check_in, "%Y-%m-%d").date()
if check_out<datetime.date.today():
self.check_out = False
# if not self.check_out:
# raise osv.except_orm('Error','Please enter the correct date')
else:
pass
@api.onchange('check_out')
def onchange_num_day(self):
if self.check_out and self.check_in:
check_in = datetime.datetime.strptime(self.check_in, "%Y-%m-%d").date()

self.days = (check_out-check_in).days+1
if self.days == 0:
self.days = 1
#Hence we will get No.of days .. Ends
字段：checked_in，checked_out，days
