Onchange problem it didnt pass the value of the fields

on 10/28/14, 11:12 PM 1,430 views

I want to get the value of L and W from PRODUCT. I use the ONCHANGE METHOD for this but it didn't work i don't know why.  I simply add the computation in the existing "onchange_porduct_id". It didn't pass the value from product to purchase. Anyone please help me Thanks in advance..



Here's my code:


 def onchange_product_id(self, cr, uid, ids, pricelist_id = False, product_id=False, qty=0.0, uom_id=False,
            partner_id=False, date_order=False, fiscal_position_id=False, date_planned=False,
            name=False, price_unit=False, metric = 0.0, lll=0.00, www=0.00, context=None):
        values = super(purchase_order_line, self).onchange_product_id(cr, uid, ids, pricelist_id, product_id, qty, uom_id,
                                                                      partner_id, date_order, fiscal_position_id, date_planned,
                                                                      name, price_unit, n, metric_tons, context=context)
        #onchange handler of product_id.
        if context is None:
            context = {}
        res = {'value': {'price_unit': price_unit or 0.0, 'name': name or '', 'product_uom' : uom_id or False}}
        if not product_id:
            return res
        product_product = self.pool.get('product.product')

Hi, Can you put xml part from that on_change is called. Means product_id field of sale order line in which you have called on_change from xml.

The result of your super method is stored in "values", but instead you return another variable named "res". Make sure the result of super is in red. Manipulate res througout your method and return it. See if that works.

thanks Ludo for answering every question of mine.. :))
