         'currency_id': 98,

         } #replace shop_id, partner_ids etc with appropriate ones if need be. 
         #note that the relation; partner_id == partner_invoice_id == partner_shipping_id has to be satisfied

#create the sale order
sale_order = oerp.create('sale.order', sale_order_dict) #that should return the sales order's id

#we've created the sale order but it doesn't have any products in it. now lets populate it with products;
#create the sale.order.order_line (with products)
##create a dictionary with fields and their values. the dict ought to have at a minimum all the fields that are marked required=True for the sale.order.line model
sale_order_line_dict = {
          'order_id': sale_order,

#create the sale.order.line
sale_order_line = oerp.create('sale.order.line', sale_order_line_dict) #returns sale.order.line id

#Now update our sale.order so that it contains the product/s in the sale.order.line we just created
order_update = oerp.get('sale.order').browse(sale_order)
order_update.order_line = [sale_order_line]
oerp.write_record(order_update)

#if you open your browser you should see the new order.

##extra stuff;
#by default if you do not specify a state field in the sale_order_dict dictionary, the sale.order will be created with a state='draft'. 
#thus the sale.order will not show up in the sale.orders but rather in the quotations section.
# the state field can take different values: 
            ('draft', 'Draft Quotation'),
            ('sent', 'Quotation Sent'),
            ('cancel', 'Cancelled'),
            ('waiting_date', 'Waiting Schedule'),
            ('progress', 'Sales Order'),
            ('manual', 'Sale to Invoice'),
            ('invoice_except', 'Invoice Exception'),
            ('done', 'Done')

#if u want the sale.order to show up in the sale.order section, you can create/update it with another state for example;
order_update = oerp.get('sale.order').browse(sale_order)
order_update.state = 'progress'
oerp.write_record(order_update)
