Ah, but this doesn't quite work for me - it seems like the CDBI functions
don't yet exist at the time the set_sql() routines are called, ie:
We see that the tables are all loaded, including the stores table:
[Fri Jul 01 11:16:41 2005] [error] [client 127.0.0.1] [Fri Jul 1 11:16:41
2005] [catalyst] [debug] Loaded tables "addresses admin_groups

email_types file_upload_info localised_forms member_types members
members_changes modified_info postcard_submission_info sections sent_email
sessions store_types stores stores_to_sections stores_to_store_types
But the next line shows us failing when the Stores.pm package is loaded:
[Fri Jul 01 11:16:41 2005] [error] [client 127.0.0.1] Couldn't load
"DieselCatalyst::M::CDBI::Stores", "Can't locate object method "set_sql" via
package "DieselCatalyst::Model::CDBI::Stores" at
/home/tobyc/svn/DieselCatalyst/lib/DieselCatalyst/M/CDBI/Stores.pm line 11.
If I remove the offending set_sql() statement, then we load alright, and
amidst the debug messages is this line, where C::M::CDBI tells us it has
automatically created the appropriate class magically:
[Fri Jul 01 11:20:17 2005] [error] [client 127.0.0.1] | DieselCatalyst::M::CDBI::Stores
Do I need to do something akin to Maypole's setup()-then-require trick?
