OpenERP : Multiple module overriding onchange function

问题

I need to override onchange_partner_id function present in sale.order but I'm working on a system that already have a module overriding this function. I tried to write my own onchange_partner_id with similar code :

def onchange_partner_id(self, cr, uid, ids, part):
    res = super(sale_order, self).onchange_partner_id(cr, uid, ids, part)
    // doing some stuff and adding it to res['value']['myfield']
return res

But my function isn't read by OpenERP. So my question is, is it possible to have multiple function overriding the same function and if i's possible how do I proceed ? Thanks in advance

回答1:

Yes you can override this method, for that you need to define new class in which inherit sale.order and define your method.

Your method will be called definitely.

class sale_order(osv.osv):
    _inherit = 'sale.order'

    def onchange_partner_id(self, cr, uid, ids, part, context=None):
        res = super(sale_order, self).onchange_partner_id(cr, uid, ids, part,context=context)
        // doing some stuff and adding it to res['value']['myfield']
        return res
