[Dbix-class] Schema::Loader and has_many

[Vsevolod (Simon) Ilyushchenko]

Brandon,

So I got the relationships to work, but now I'm trying to turn on 
session support via Catalyst::Plugin::Session::Store::DBIC, and it's 
seems incompatible with the Loader. The test script t/05dbic-schema.t 
seems to be using schemas, but not the loader, and I can't reconcile the 
two.

Here's the furthest I've gotten -  Catalyst::Model::DBIC::Schema->new 
should create the method ACCEPT_CONTEXT in the model class, which 
enables Session::Store::DBIC to work properly. This method is created on 
line 188.

For the script t/05dbic-schema.t, the value of $class is 
'TestApp::Model::DBICSchema', and the value of $moniker is 'Session', so 
the method is created in TestApp::Model::DBICSchema::Sesion. (The 
TestApp code is in the t/lib subdirectory of 
Catalyst::Plugin::Session::Store::DBIC).

In my app at this point, $class is 'CSHL::Cat::Proto::M::Session', and 
$moniker iterates over all my model class names, including 'Session', so 
the ACCEPT_CONTEXT is uselessly created in 
'CSHL::Cat::Proto::M::Session::Session' etc.

The difference between the applications is that I have the recommended 
setup of App::Schema.pm, App::Schema::Session.pm and App::M::Session.pm 
(which is ISA Catalyst::Model::DBIC::Schema, as recommended). While 
TestApp::Model::DBIC::Session is ISA TestApp::Model::DBIC, plus they 
have TestApp::Model::DBICSchema, which is ISA 
Catalyst::Model::DBIC::Schema.

I'm not sure how to tie these approaches together.

Thanks,
Simon
