One option is to pass in the parent object reference (session.user)
when you create the order and have the order remember it:
<cfscript>
if ( not structKeyExists(session.user,"order") ) {
order = createObject("component", "cfc.order");
order.init( session.user );
session.user.order = order;
}
</cfscript>
And inside order.cfc:
<cfcomponent>
<cfset instance = structNew()/>
<cffunction name="init" returntype="void">
<cfargument name="parent" type="cfc.user"/>
<cfset instance.parent = arguments.parent/>
</cffunction>
... rest of order.cfc ...
... instance.parent is owning user ...
</cfcomponent>
A couple of things to note here:
- 'init()' matches what you do when manipulating Java objects (create,
init)
- 'init()' returns void - meaning "I return nothing"
- 'instance' is convenient way to handle non-public instance data
