I'm not understanding your full train of thought. The only ways I saw this happening were: a- Strip DB + Meta on serialize. On re-materialize build in new db + meta into the object b- Strip DB + Meta on serialize. On re-materialize transfer object contents to a new rdob.obj and we'd need to loop each object for the right information to strip or not. What's to loop? Just clearing meta and the dbh would make a nicely serializable object, as far as I can tell. well the object meta is all over the place - i'm not sure what functions you use to tell which xrdo_priv meta attributes are set . in my approaches thus far, to strip i'm looping through the object looking for __xrdo prefix // Jonathan Vanasco | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | SyndiClick.com | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | FindMeOn.com - The cure for Multiple Web Personality Disorder | Web Identity Management and 3D Social Networking | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | RoadSound.com - Tools For Bands, Stuff For Fans | Collaborative Online Management And Syndication Tools | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Re: [RDBO] dbh caching

What about using Ima::DBI? Would that stomp on RDB?
I doubt it. A Rose::DB object shouldn't care much what class its dbh is, so
long as it acts appropriately like a plain DBI dbh.
Sorry, just getting back to this.
I'm missing something critical -- or something obvious:
This works fine in my base class:
sub init_db { our $DBH =|| App::RDB-new }
I've got the same $dbh for the life of the program.
But, I'd like to try using DBI-connect_cached directly.
I first tried returning $dbh directly in the init_db call. That's
were I misunderstood your comments, I guess.
So, then I tried passing a dbh param to App::RDB-new:
sub init_db {
...
my $dbh = DBI-connect_cached( @params );
return App::RDB-new( dbh = $dbh );
}
Where @params does not change between calls. I then get a new $dbh.
for new RDBO objects.
So, I'm not seeing how to correctly do this.
Thanks,
