Hello,

I'm working on odoo9. I'm facing one issue in which i have 1 One2many field in the sale order line and for the relation there is 1 Many2one field.

Now in the One2many field class, there is 1 Many2one field to another object.

On the click of button, i write some data in the sale order line's One2many fields and it is written also correctly.

But, now in the Many2one field, display _unknown,id instead of just id.

For more Info:-

class SaleOrderLine(models.Model):

     _inherit = 'sale.order.line'

    lot_line_ids = fields.One2many('lot.line.detail', 'line_id', 'Lot Ids')

class LotLineDetail(models.Model):

    _name = 'lot.line.detail'

    _description = "Lot Line Detail"

    line_id = fields.Many2one('sale.order.line', 'Sale Order Line')

    lot_line_id = fields.Many2one('lot.detail', string='Lot Line Id')

    lot_line_qty = fields.Float('Quantity')

In the lot_line_id, i have facing _unknown error.

Thanks in advance,
