How to add functionality to the osv class?

Question

How to "directly" override a method in the osv Model class, such as write, create, etc, so that any new model that I create inherits this functionality?
I mean, suppose I am extending res.partner, sale.order, purchase.order and a bunch of other models, and I want to override write for all of them, adding the same code to every one (like logging or something). Can I do this without overriding write in every single model?

Hi Julian,

def unlink(self, cr, uid, ids, context=None):

--- custome code --

after creating your method add this code

osv.osv.unlink = unlink
now your method is overrided the osv method

You can do as you want. Just see the following ex for the write method. It is override the write method of the osv.

from openerp.osv import orm

def custom_write(self, cr, uid, ids, vals, context=None):

..... Your code ...

return True

orm.BaseModel.write = custom_write
