Whow to overrride a méthod in Openerp

Asked by EL HADJ MIMOUNE Mourad

Hi everybody,

I want override a method price_get of the pricelist class to custom price computing.
So I make this by inheritance (see code below). The problem is still the original method that is triggered!

What's wrong ?

class product_pricelist(osv.osv):
    _name = 'product.pricelist'
    _inherit = 'product.pricelist'

    def price_get(self, cr, uid, ids, prod_id, qty, partner=None, context=None):
        re = super(product_pricelist, self).price_get(cr, uid, ids, prod_id, qty, partner, context)
        res_multi = self.price_get_multi(cr, uid, pricelist_ids=ids, products_by_qty_by_partner=[(prod_id, qty, partner)], context=context)
        res = res_multi[prod_id]
        res.update({'item_id': {ids[-1]: ids[-1]}})
        return res

Thank you for your help

Make sure you have added your custom python to the __init__.py file, and also that you have instantiated the class:

class product_pricelist(osv.osv):
     <snip>
     ...
     </snip>

product_pricelist() # this instantiates the class

HEllo.

If you use:

_name = 'product.pricelist'

You are creating a new model that overriveenterally the old one, don't use this and you will override JUST the method.

Thank's for your response.

in the __init__ I have set
import product_pricelist_test (which is the name of the python file)

And class product_pricelist() are still initializied.

I delete the line _name = 'product.pricelist' but no thing changed.
I searched for many time without find a solution.

All suggestion are welocome

Did you restart the server? I've found that when you modify .py files, you will need to delete the .pyc and restart the server, so that the old classes are not cached in memory.

You just need to restart, the pyc almost always regenerate.

Hello,
Thanks for your responses.
I resolved my problem with deleting the line:
 re = super(product_pricelist, self).price_get(cr, uid, ids, prod_id, qty, partner, context)
and with adding Link to my module folder.
In fact, when I run openerp-server from Eclipse (debug mode), it use de folder bin/addons.
For updating module I used --addons-path=... option. So module was installed but not used.

To make link
cd server/bin/addons
ln -s ../../../addons/* .

Best regards
