I have 2 modules and there is no One2many/Many2one linking between these 2 .

So I want to create these linkings to get the "age" field from stock.move in stock.production.lot

class moveds(models.Model): 

          _inherit="stock.move" 

          age = fields.Char()

          lots=fields.One2many('stock.production.lot','moves',copy=True)

 class moveLot2(models.Model): 

           _inherit="stock.production.lot"

           moves=fields.Many2one('stock.move')

           age2 = fields.Char(related='moves.age', store=True)

So I want to get in my "age2" field the value of "age", there is no error, but age2 is empty,  the linking is correct between o2m and m2o?
