NAME¶
Catalyst::TraitFor::Model::DBIC::Schema::SchemaProxy - Proxy Schema Methods and
Options from Model
DESCRIPTION¶
Allows you to call your DBIx::Class::Schema methods directly on the Model
instance, and passes config options to your DBIx::Class::Schema and
DBIx::Class::ResultSet attributes at "BUILD" time.
Methods and attributes local to your "Model" take precedence over
DBIx::Class::Schema or DBIx::Class::ResultSet methods and attributes.
CREATING SCHEMA CONFIG ATTRIBUTES¶
To create attributes in your "Schema.pm", use either Moose or
Class::Accessor::Grouped, which is inherited from by all DBIx::Class classes
automatically. E.g.:
__PACKAGE__->mk_group_accessors(simple => qw/
config_key1
config_key2
...
/);
Or with Moose:
use Moose;
has config_key1 => (is => 'rw', default => 'default_value');
This code can be added after the md5sum on DBIx::Class::Schema::Loader generated
schemas.
At app startup, any non-local options will be passed to these accessors, and can
be accessed as usual via "$schema->config_key1".
These config values go into your "Model::DB" block, along with normal
config values.
CREATING RESULTSET CONFIG ATTRIBUTES¶
You can create classdata on DBIx::Class::ResultSet classes to hold values from
Catalyst config.
The code for this looks something like this:
package MySchema::ResultSet::Foo;
use base 'DBIx::Class::ResultSet';
__PACKAGE__->mk_group_accessors(inherited => qw/
rs_config_key1
rs_config_key2
...
/);
__PACKAGE__->rs_config_key1('default_value');
Or, if you prefer Moose:
package MySchema::ResultSet::Foo;
use Moose;
use MooseX::NonMoose;
use MooseX::ClassAttribute;
extends 'DBIx::Class::ResultSet';
sub BUILDARGS { $_[2] } # important
class_has rs_config_key1 => (is => 'rw', default => 'default_value');
...
__PACKAGE__->meta->make_immutable;
1;
In your catalyst config, use the generated Model name as the config key, e.g.:
<Model::DB::Users>
strict_passwords 1
</Model::DB::Users>
