I am working on customizing the purchase module, in which i need to save the content of the purchase order in a newly created table whenever the purchase order is confirmed. I have developed a module in order to save the content to the table using create function but finally i got some errors. Please any one give some idea how to clear this error

This is the code

class inherit_purchase_update(models.Model):
    
    _inherit='purchase.order'
    

    def wkf_confirm_order(self, cr, uid, ids, context=None):
        id1=ids
        recs= self.pool.get('purchase.order.line').browse(cr,uid,id1,context=context)
        recd= self.pool.get('purchase.update').browse(cr,uid,ids,context=context)
        for rec in recs:
            cust_id=rec.partner_id.id
            price_unit= rec.price_unit
            prod_id= rec.product_id.id
            date_order=rec.order_id.date_order
            prod_qty= rec.product_qty
            rec1=recd.create(cr,uid,{'partner_id':cust_id,'date':date_order,'product_id':prod_id,'price_unit':price_unit,'product_qty':prod_qty})

ValueError: "create() takes exactly 2 arguments (4 given)" while evaluating u'wkf_confirm_order()'
