Hello, 
I have inherited and added a field in stock.move and I have added it to account.move.line  as a related field yet it is not being displayed in the latter module.
How can I go about this.

Thanks in advance.

My code.

class StockMove (models. Model):
_inherit = 'stock. move' 

def _prepare_account_move_line ( self , move ):
​res = super (AccountMoveLine , self )._prepare_account_move_line( move )
​res. update({
​ ​"net_weight" : self . net_weight
​})
​return res

net_weight = fields.Integer( string = "Net Weight" , store = True )


class AccountMoveLine (models.Model):
_inherit = 'account.move.line' 

net_weight = fields.Integer(related='move_id.net_weight', string="Net Weight", store=True, readonly=False)
