My code is here and what i want to do is to calculate total sub total from item_seller_price if price_unit is 0... but when the code runs it didnt gave Description in purchase order neither Scheduled Date nor Subtotal

from openerp.osv import osv, fields
class purchase_order_line(osv.osv):
_inherit ='purchase.order.line'
_columns = {
'item_seller_price' : fields.float('Item Seller Price'),
def _amount_all(self, cr, uid, ids, field_name, arg, context=None):
res = {}
for order in self.browse(cr, uid, ids, context=context):
res[order.id] = {
'amount_untaxed': 0.0,
'amount_tax': 0.0,
'amount_total': 0.0,
val = val1 = 0.0
cur = order.pricelist_id.currency_id
for line in order.order_line:
price_unit = line.price_unit
if line.item_seller_price != 0:
price_unit = line.item_seller_price
val1 += line.price_subtotal
for c in self.pool.get('account.tax').compute_all(cr, uid, line.taxes_id, line.price_unit, line.product_qty, line.product_id, order.partner_id)['taxes']:
val += c.get('amount', 0.0)
res[order.id]['amount_tax']=cur_obj.round(cr, uid, cur, val)
res[order.id]['amount_untaxed']=cur_obj.round(cr, uid, cur, val1)
res[order.id]['amount_total']=res[order.id]['amount_untaxed'] + res[order.id]['amount_tax']
return res
