how to add a field related on odoo
I would like to add a text field on stock.move related to stock.picking origin field
I tried this :

_columns={       
    'sourcebl': fields.related('picking_id', 'origin',  type='char', relation='stock.picking', string='Class Description', store=True, readonly=True),
          }

do you have any Idea

回答1:

You can find more information here : Link

In the new API, there is not anymore fields.related. You should define your related field like this :

   sourcebl = fields.Char(string='Class Description', related='picking_id.origin')

I used the old api it work fine now :

_columns={
'sourcebon': fields.related('picking_id', 'origin', string="Origin", type="char",store=True, readonly=True),
}
