[Catalyst] Catalyst::Model::DBIC::Schema and result classes

[Richard Jolly]

Hi,

I'm trying to get started with C::M::DBIC::Schema. I have an existing
schema defined, but C::M::DBIC::Schema does not seem to be picking up
custom result_classes .

The schema is defined like:

PIP::Schema;
PIP::Schema::Pip           # source/table definitions
PIP::ResultSet::Pip         # custom resultset classes
PIP::Pip                         # result class additional methods

(there is more of course, but in the same pattern)

The catalyst app looks like:

Pips3::M::PIP;               # C::M::DBIC::Schema

No other classes are defined under M.

The error I'm getting is:

  "Can't locate object method "ce" via package "Pips3::M::PIP::Pip"

where ce is definded in PIP::Pip, and the call in the controller looks
like:

    my $obj = $c->model('PIP::Pip')->find($id)->ce;

In the debugger:

  DB<12> x ref $c->model('PIP')
  0  'Pips3::M::PIP'

  DB<8> x ref $c->model('PIP::Pip')
  0  'PIP::ResultSet::Pip'                          # looks good
  
  DB<9> x $c->model('PIP')->class('Pip')
  0  'Pips3::M::PIP::Pip'                           # I would expect
PIP::Pip here

So where does Pips3::M::PIP::Pip come from?

I tried making a minimal Pips3::M::PIP::Pip package:
  
  package Pips3::M::PIP::Pip;
  use base qw/PIP::Pip/;
  1;

But that gives me a C3 merge error:

"Inconsistent hierarchy found while merging 'Pips3::M::PIP::Pip':
        current merge results [
                Pips3::M::PIP::Pip
        ]
        merging failed on 'PIP::Schema::Pip'"

I CAN get around this by changing use base to unshift @ISA, but that
doesn't feel right.

So - where have I gone wrong, and how should I resolve it?

Thanks,

Richard
