Question

我是odoo 9社区的新手。我已经在我的自定义模块中创建了很多2个文件继承了sale.order.line，我想为那个many2one字段设置默认值，条件是fto调用funscion是产品那个随附物料清单。达到这个目的的步骤是什么？谢谢你的时间。

Answer 1

举个例子，我在这里将产品属于sale.order中选择的仓库，并将其返回product_id中的sale.order.line。

obj_location = self.pool.get('stock.warehouse').browse(cr, uid, warehouse_id, context=context).lot_stock_id.id
obj_inventory = self.pool.get('stock.quant').search(cr, uid, [('location_id', '=', obj_location)])
product_ids = []
products_qty = []
    for obj in obj_inventory:
            obj_products_id = self.pool.get('stock.quant').browse(cr, uid, obj)
            product_ids.append(obj_products_id.product_id.id)
return {'domain': {'product_id': [('id', 'in', product_ids)]}}

class unit_rate（models.Model）：

_name = "sale.order.line.width"

name = fields.Char(u'Tên', required=True)
rate = fields.Float(u'Hệ số', required=True, default=1)
unit_id = fields.Many2one('product.uom', string=u'Đơn vị', required=True)
description = fields.Text(u'Chú thích')

类SaleLine（models.Model）：

_inherit = "sale.order.line"
@api.model
def create(self, vals):
    if vals['rate'] < 1:
        raise UserError(_(u'Không thể đưa vào hệ số nhỏ hơn 0'))
    return super(unit_rate, self).create(vals)

_inherit = "sale.order.line"

width_id = fields.Many2one('sale.order.line.width', u'Kiểu tính')

如何设置many2one字段的默认值？
