Inheriting old methods in version 8

When I write a custom module that overrides the current methods, does it need to be written in the same api version?

For example, a module product is written in v7, when I override product methods, does it need to be in v7 or can I do it in v8?

You only need to update the odoo engine code, which itself manages the update / downgrade engine as needed.

from openerp import models, fields, api, _

class product_product(models.Model):
    _inherit= "product.product"
    _description = "Product"

    @api.model
    def create(self, vals):
        ### Add your code here
        return super(product_product, self).create(vals);

    @api.multi
    def write(self, vals):
        ### Add your code here
        return super(product_product, self).write(vals);


Likewise, you can override any legacy methods except exchange methods. in onchange methods, you need to provide the definition in the old template.

yes, you can override v8 method in v7

from openerp import models, fields, api, _

class product_product(models.Model):
    _inherit= "product.product"
    _description = "Product"

@api.v7
def _product_code(self, cr, uid, ids, name, arg, context=None):
    res = {}
    if context is None:
        context = {}
    for p in self.browse(cr, uid, ids, context=context):
        res[p.id] = self._get_partner_code_name(cr, uid, [], p, context.get('partner_id', None), context=context)['code']
    return res


I am just overriding v7 _product_code method

in my new API product class for Odoo 8.0.

Hope my answer can help you :)
