Hi,

I am creating the module for Restaurant Management. I added the tabs like Table Booking, Orders, Kitchen Order Ticket(KOT)

where, Orders are taken and KOT is generated.

Now, I want to generate Invoice after generating KOT. I just want the value of TOTAL (amount_total) field on Orders tab should get invoiced and the TOTAL gets added. After that, It should creates Invoice on clicking the Generate Invoice Button.

Here is my code,

hotel_restaurant.py -------------------------------------------------------------------

class hotel_restaurant_order(osv.Model):

        def _sub_total(self, cr, uid, ids, field_name, arg, context=None):

        res = {}

        for sale in self.browse(cr, uid, ids, context=context):

            res[sale.id] = sum(line.price_subtotal for line in sale.order_list)

        return res

        def _total(self, cr, uid, ids, field_name, arg, context=None):

        res = {}

        for line in self.browse(cr, uid, ids, context=context):

        res[line.id] = line.amount_subtotal + (line.amount_subtotal * line.tax) / 100

        return res

        def generate_kot(self, cr, uid, ids, part):

        order_tickets_obj = self.pool.get('hotel.restaurant.kitchen.order.tickets')

        restaurant_order_list_obj = self.pool.get('hotel.restaurant.order.list')

        for order in self.browse(cr, uid, ids):

        table_ids = [x.id for x in order.table_no]

        kot_data = order_tickets_obj.create(cr, uid, {

        'orderno':order.order_no,

        'kot_date':order.o_date,

        'room_no':order.room_no.name,

        'w_name':order.waiter_name.name,

        'tableno':[(6, 0, table_ids)],

        })

        for order_line in order.order_list:

        o_line = {

        'kot_order_list':kot_data,

        'name':order_line.name.id,

        'item_qty':order_line.item_qty,

}

        restaurant_order_list_obj.create(cr, uid, o_line)

        return True
