Return value in sales.order.line from wizard in Odoov10 - python-2.7

Question

I have a Many2many type field in wizard('pack_ids') and also a Many2many('pack_id') type field in sale.order.line. And i want that the value of Many2many type field of wizard('pack_ids') return in sale.order.line field('pack_id').
For this my code is here:
class SalePackWizard(models.TransientModel):
_name = "sale.pack.wizard"
_description = "Sale Pack Wizard"
#api.onchange('product_id')
def _onchange_product_pack_name(self):
print"A:", self.product_id.product_pack
res = self.product_id.product_pack
a = {}
print "res:", res
if res:
domain = {'pack_ids': [('id', 'in', [v.id for v in res])]}
a= res
print "a:", a
return {'domain': domain}
product_id = fields.Many2one('product.product', string="Product Pack", required=True, domain="[('is_pack','=',True)]")
qty = fields.Float(string='Quantity', digits=dp.get_precision('Product Unit of Measure'), required=True, default=1.0)
pack_ids = fields.Many2many('product.pack', string='Pack Products', change_default=True,
default=_onchange_product_pack_name)
#api.multi
def action_salepack_add(self):
rec = self._context.get('active_ids', [])
print "REC", rec, self.product_id.categ_id #product_uom
if rec:
line_values = {'product_id': self.product_id.id,
#'design_id':self.design_id.id,
'pack_id': self.product_id.product_pack,
'category_id':self.product_id.categ_id.id,
'order_id':rec[0],
'product_uom_qty':self.qty,
}
sale_order_line = self.env['sale.order.line'].create(line_values)

Answer 1

you can update your code by that:
#api.multi
def action_salepack_add(self):
order_id = self._context.get('active_id',False)
if order_id:
line_values = {'product_id': self.product_id.id,
'pack_id': [ ( 6, 0, [self.product_id.product_pack.id] ) ],
'category_id':self.product_id.categ_id.id,
'order_id':order_id,
'product_uom_qty':self.qty,
}
sale_order_line = self.env['sale.order.line'].create(line_values)
You cant create values in a many2many field just giving it the id (this is only for many2one). If the field is a one2many or many2many:
(0, 0, { values }) link to a new record that needs to be created with the given values dictionary
(1, ID, { values }) update the linked record with id = ID (write values on it)
(2, ID) remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well)
(3, ID) cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself)
(4, ID) link to existing record with id = ID (adds a relationship)
(5) unlink all (like using (3,ID) for all linked records)
(6, 0, [IDs]) replace the list of linked IDs (like using (5) then (4,ID) for each ID in the list of IDs)

Answer 2

Error Fixed. Here is the solution for error:
#api.multi
def action_salepack_add(self):
rec = self._context.get('active_ids', [])
print "REC", rec, self.product_id.categ_id #product_uom
if rec:
line_values = {'product_id': self.product_id.id,
#'design_id':self.design_id.id,
'pack_id': [(6, 0, [v.id for v in self.product_id.product_pack])],
'category_id':self.product_id.categ_id.id,
'order_id':rec[0],
'product_uom_qty':self.qty,
}
sale_order_line = self.env['sale.order.line'].create(line_values)
