Odoo - one2many 总和
Odoo - one2many sum
我正在做一个简单的项目,但遇到了问题。我想对我的 one2many 字段中的一列求和,我该怎么做?
from openerp import models, fields, api, _
class Fam(models.Model):
_name = 'fam'
fm_id = fields.Many2one('fam')
mileage = fields.Float(string="Mileage", required=True)
fueled = fields.Float(string="Fueled", required=True)
perliter = fields.Float(string='Price per liter', required=True)
class Car2(models.Model):
_name = 'car2'
_description = 'Car record'
_log_access = True
name = fields.Char(
string='Name',
required=True
)
mile = fields.One2many(
"fam",
"fm_id",
string='Mileage, Fuel and cost perliter',
required=True
)
average = fields.Float(
string='Average'
)
combustion = fields.Float(
string='Combustion'
)
您可以通过以下示例实现:
for line in self.one2many_field_name:
total += line.field_name_in_one2many_table
# in your case
total_mileage = 0.0
total_fueled = 0.0
total_perliter = 0.0
for line in self.mile:
total_mileage += line.mileage
total_fueled += line.fueled
total_perliter += line.perliter
