Override many2one with many2many



I try to override many2one field with many2many

File "/home//workspace/odoo-9.0/openerp/models.py", line 5384, in _browse
env.prefetch[cls._name].update(ids)

I would suggest you not to do that because if a Many2one field already exists, it must be used at many different places and you will have errors everywhere, because a singleton is expected instead of a list. You should create another field instead.

Best solution I came up with.


multiply_pricelists_ids = fields.Many2many(
'product.pricelist', string='Multiply Pricelists')

@api.onchange('property_product_pricelist')
@api.multi
def pricelist_change(self):
self.multiply_pricelists_ids = self.property_product_pricelist
