Subject RE: referencing foreign keys in other packages
Date Fri, 30 Sep 2005 14:18:24 GMT
AFAIK, the beans are just repackaging of the normal Torque table 
classes.  Since the base classes are all public, there should
not be a security problem if the create<Bean> methods are public.

Why don't you submit your template modes via a Scarab enhancement

IMHO, unless you are running a secured class loader, the method
modifiers are just there to warn other developers that "there 
be dragons here".. if you want to use it.  Not a big problem if 
you have access to the source code or the docs spells out the 
"contract" properly. But it can sometimes lead to major headaches 

As to referring to other db packages, I noticed that the code
Database class in the OM has a package attribute that is setable
via a package="...." attribute.  I'm not enough of a template
guru to say for sure, but it seems like there should be a way 
get the list of databases being generated and run thru them to 
automatically create a set of imports.  This would replace the
need for the ant replace task. 

Hmm, maybe you could do it by adding with something like the
following to the appropriate templates:

#set $currentPackage = $table.Database.Package
#foreach ($col in $table.Columns)
        #if  $col.Table.Database.Package != $currentPackage )
            import ${col.Table.Database.Package}.${col.BaseClass};

Good luck.
