[Helma-user] Sample of relationships

[Maksim Lin for technical support mailling lists]

Hi,

If I understand your question correclty, it sounds like you need to
create 3 Prototypes:

Customer
Order
OrderItem

To do that, create folders with those names in your helma app folder.
Assuming you call you app orders-app you need to have:

helma-1.6.0/apps/orders-app
helma-1.6.0/apps/orders-app/Customer
helma-1.6.0/apps/orders-app/Order
helma-1.6.0/apps/orders-app/OrderItem

then in each you will need an appropriate type.properties file

Customer/type.properties:

name
address
order = object(Order)

Order/type.properties:

items = collection(OrderItem)

OrderItem/type.properties:
 
widgetName
quantity
price


(Of course I just made up the above properties for customers and
orderitems - you would use whatever you need for your business data).

The above type.proeprties is just using the builtin xml-based database.
If you need to use a SQL DB (like MySQL) you need to have a extra
settings, see here for more info on that:
http://helma.org/docs/guide/mapping/

I also highly recommend working through the tutorial:
http://helma.org/docs/tutorial/

hope that helps,

Maks.
