[Dbix-class] Using and inter-linking multiple databases via DBIC: "Can't find source"

[will trillich]

We are using Catalyst for a web app. We've split off the authentication
database to facilitate multiple different apps using the same user
credentials, but we're having trouble linking the auth db to the biz-info
db.

The generalized user/team credentials and related info are in Auth, and the
actual business info for this app is in DB. Here's an object from the DB
database:


package Learn::Schema::DB::Result::TeamEmail;

#...
__PACKAGE__->belongs_to( team =3D> 'Learn::Schema::Auth::Result::Team' );


Note that we're trying to get DB::TeamEmail to refer to Auth::Team here.
And below is the related object from the Auth database:


package Learn::Schema::Auth::Result::Team;

#...
__PACKAGE__->has_many( emails =3D> 'Learn::Schema::DB::Result::TeamEmail',
'team' );


At this point we expect

*$team->emails_rs*

to work but instead we get

Can't find source for Learn::Schema::DB::Result::TeamEmail

because TeamEmail isn't in $self->source_registrations (full names) or
$self->class_mappings (brief names) in the DBIx::Class::Schema::source()
method.


Pointers? Is there a different approach? Got a clue stick?
