在 Odoo 8 中添加迄今为止的月份

Question

我希望此模块从两个字段计算到期日期，即制造日期和 bbm（最好在几个月之前）。到期字段应添加制造日期、bbm 并将其值显示为只读。下面是我正在使用的代码。

class omfed_items(osv.Model):
"""
items or products profilling
"""
_name = 'omfed.items'
_description = 'omfed items'
_order = 'code asc'

_columns = {
    'name': fields.char('Name', required=True),
    'code': fields.integer('Code', required=True),
    'category_id':fields.many2one('omfed.category','Category',required=True),
    'mfg_date':fields.date('Manufacturing Date'),
    'p_manager':fields.many2one('hr.employee','Product Manager'),
    'bbm':fields.integer('Best before use (in Months)'),
    'exp_date':fields.date(compute='addmonths', string="Expiry Date"),
}
def addmonths(self):
   try:
       targetdate = omfed_items.mfg_date
       targetmonths = omfed_items.bbm+targetdate.month
       if targetmonths%12 == 0:
            targetmonth = 12
       else:
            targetmonth = targetmonths%12
            if favorEoM == True:
                testdate = date+datetime.timedelta(days=1)
                if testdate.day == 1:
                    targetdate.replace(year=targetdate.year+int((targetmonths+1)/12),month=(targetmonth%12+1),day=1)
                    targetdate+=datetime.timedelta(days=-1)
                else:
                    targetdate.replace(year=targetdate.year+int(targetmonths/12),month=(targetmonth))
            else:
                targetdate.replace(year=targetdate.year+int(targetmonths/12),month=(targetmonth))
            return targetdate
   except:
     targetdate.replace(year=targetdate.year+int((targetmonths+1)/12),month=(targetmonth%12+1),day=1)
     targetdate+=datetime.timedelta(days=-1)
     return targetdate

class omfed_category(osv.Model):
    """ category """
    _name = 'omfed.category'
    _description = 'omfed category'
    _columns={
        'name': fields.char('Category Name',required=True),
        'code': fields.integer('Category Code',required=True),
        'items_id':fields.one2many('omfed.items','category_id','Items'),
    }

提前感谢您的解决方案。

Answer 1

您可以使用以下代码：

from datetime import datetime, timedelta
self.exp_date = datetime.strptime(self.mfg_date, '%Y-%m-%d') + timedelta(days=(self.bbm * 30))
