Assuming MyApp::Model::MyApp is your DBIC::Schema model
$c->model('MyApp')->schema;
is what you want.
$c->model('MyApp::Foo')
is just a shortcut for
$c->model('MyApp')->schema->resultset('Foo')
If you only have a $row or a $rw, then
$obj->result_source->schema
will get you back to the schema.
For more information, read the DBIx::Class::ResultSet, ::ResultSource,
::Schema and ::Row docs, plus the docs for Catalyst::Model::DBIC::Schema
itself.
Please also note that dbix-class has its own list so any more DBIC-specific
questions should go there.
