Hi folks,
I've been looking at how to best implement persistence in my recent
reporting engine project. It seems the most effective (and by chance the
easiest to implement) way is to just throw the main Report object into
session scope. (I need persistence to support paging in html output)
My question is...should the logic of "knowing whether to add the report
object to session scope" reside in a "ReportManager" of sorts?
I'm confused though as to how I would invoke a Report object, should all
my calls go thru the Manager? Do I have to duplicate all the methods in
the Manager?
This is what I'm doing now - Example:
// Create a dataset - essentially a query or stored proc
myDataset = CreateObject("component","Dataset").init( myQueryFileTarget,
myDatasource);
// Create report and add dataset to it - can contain multiple datsets
myReport = CreateObject("component","Report").init();
myReport.addDataset( myDataset );
myReport.setTitle("Bogus Report Name Here");
// This causes all datasets to populate via their queries
myReport.execute();
But sometimes I need to do the following...but I don't want to have the
session manipulation performed outside of the model:
// Create a dataset - essentially a query or stored proc
myDataset = CreateObject("component","Dataset").init( myQueryFileTarget,
myDatasource);
// Create report and add dataset to it - can contain multiple datsets
Session.myReport = CreateObject("component","Report").init();
Session.myReport.addDataset( myDataset );
Session.myReport.setTitle("Bogus Report Name Here");
// This causes all datasets to populate via their queries
Session.myReport.execute();
As always, appreciate ur insight
