Question

我只想知道如何使用计算字段计算在one2many中设置值。我的代码是

python文件

npm info it worked if it ends with ok
npm info using npm@2.15.11
npm info using node@v4.6.2
npm info prestart installation@1.0.0
npm info start installation@1.0.0

    vals = {}
    vals.update({'monthly_lines':[(0,0,{'month_name_id':1,'so_qty':35})]})
    self.write(vals) # Also I have tried self.monthly_lines = [(0,0,{'month_name_id':1,'so_qty':35})]

class minmax_monthly_data(models.Model):
    _name = 'minmax.monthly.data'

    month_id = fields.Many2one('product.product', 'Product Reference', select=True, required=True)
    month_name_id = fields.Many2one('minmax.months','Minmax Month',required=True)
    so_qty = fields.Float('Sales Qty', digits_compute=dp.get_precision('Product Unit of Measure'), required=True)

这里我尝试手动插入数据。每当我们加载product.product树视图时，都会正确调用该函数。但没有结果。提前谢谢。

在您的代码中，您没有指定记录哪个产品属于，这就是为什么这条记录没有被映射到任何one2many 记录，因为没有定义many2one引用。意味着你需要在 minmax.monthly.data 模型中设置 month_id 然后你就可以了查看 product.product 中one2many字段中的数据。

你的代码应该是那样......

class extend_product_product(models.Model):
    _inherit = 'product.product'

    monthly_lines = fields.One2many('minmax.monthly.data','month_id', 'Monthy Sales',compute="_get_monthly_sales")

    @api.multi
    def _get_monthly_sales(self):
        for rec in self:
            rec.monthly_lines = [(0,0,{'month_name_id':1,'so_qty':35, 'month_id' : rec.id})]

在新的api功能字段中直接分配对象，我们不需要像旧版本那样返回字典。

这些功能字段可以存储到数据库中，因为您只需要在字段定义中设置store = True属性。

如果你将字段存储在数据库中，那么在这种情况下我们也需要更新它的值，因为你需要用@api.depends('field name1','field name2')来装饰函数

@api.multi
@api.depends('fieldname')
def _get_monthly_sales(self):
    for rec in self:
        rec.monthly_lines = [(0,0,{'month_name_id':1,'so_qty':35,'month_id' : rec.id})]

当您设置时，可以通过odoo框架自动管理One2many字段记录中有多个参考，然后逆模型具有one2many 关系和将自动管理（One2many字段需要定义）。但是你可以管理 One2many，这是双向的，所以你需要管理很多人或者一个人。
