I want overwrite the _get_order and print_quotation methods from the purchase module. My code below only works for the print_quotation method but not for _get_order method. I had the same problem with other methods like _minimum_planned_date .

I added the colums definition to my new purchase.py file experimentally. In this case both methods my _get_order method and the orginal _get_order method were executed.

Thanks

My code

class purchase_order(orm.Model):
    _inherit='purchase.order'
    _name='purchase.order'

    def print_quotation(self, cr, uid, ids, context=None):
         print "### my quotation used"
        res = super(purchase_order, self).print_quotation( cr, uid, ids,context)
        return res

    def _get_order(self, cr, uid, ids, context=None):
       print "### my _get_order" ...
