.\" way too many mistakes in technical documents.

.SH "NAME"
Catalyst::TraitFor::Model::DBIC::Schema::SchemaProxy \- Proxy Schema Methods and
Options from Model
.SH "DESCRIPTION"
.IX Header "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 \f(CW\*(C`BUILD\*(C'\fR time.
.PP
Methods and attributes local to your \f(CW\*(C`Model\*(C'\fR take precedence over
DBIx::Class::Schema or DBIx::Class::ResultSet methods and attributes.
.SH "CREATING SCHEMA CONFIG ATTRIBUTES"
.IX Header "CREATING SCHEMA CONFIG ATTRIBUTES"
To create attributes in your \f(CW\*(C`Schema.pm\*(C'\fR, use either Moose or
Class::Accessor::Grouped, which is inherited from by all DBIx::Class
classes automatically. E.g.:
.PP
.Vb 5
\&    _\|_PACKAGE_\|_\->mk_group_accessors(simple => qw/
\&        config_key1
\&        config_key2
\&        ...
\&    /);
.Ve
.PP
Or with Moose:
.PP
.Vb 2
\&    use Moose;
\&    has config_key1 => (is => \*(Aqrw\*(Aq, default => \*(Aqdefault_value\*(Aq);
.Ve
.PP
This code can be added after the md5sum on DBIx::Class::Schema::Loader
generated schemas.
.PP
At app startup, any non-local options will be passed to these accessors, and can
be accessed as usual via \f(CW\*(C`$schema\->config_key1\*(C'\fR.
.PP
These config values go into your \f(CW\*(C`Model::DB\*(C'\fR block, along with normal config
values.
.SH "CREATING RESULTSET CONFIG ATTRIBUTES"
.IX Header "CREATING RESULTSET CONFIG ATTRIBUTES"
You can create classdata on DBIx::Class::ResultSet classes to hold values
from Catalyst config.
.PP
The code for this looks something like this:
.PP
.Vb 1
\&    package MySchema::ResultSet::Foo;
\&
\&    use base \*(AqDBIx::Class::ResultSet\*(Aq;
\&
\&    _\|_PACKAGE_\|_\->mk_group_accessors(inherited => qw/
\&        rs_config_key1
\&        rs_config_key2
\&        ...
\&    /);
\&    _\|_PACKAGE_\|_\->rs_config_key1(\*(Aqdefault_value\*(Aq);
.Ve
.PP
Or, if you prefer Moose:
.PP
.Vb 1
\&    package MySchema::ResultSet::Foo;
\&
\&    use Moose;
\&    use MooseX::NonMoose;
\&    use MooseX::ClassAttribute;
\&    extends \*(AqDBIx::Class::ResultSet\*(Aq;
\&
\&    sub BUILDARGS { $_[2] } # important
\&
\&    class_has rs_config_key1 => (is => \*(Aqrw\*(Aq, default => \*(Aqdefault_value\*(Aq);
\&
\&    ...
\&
\&    _\|_PACKAGE_\|_\->meta\->make_immutable;
\&
\&    1;
.Ve
.PP
In your catalyst config, use the generated Model name as the config key, e.g.:
.PP
.Vb 3
\&    <Model::DB::Users>
\&        strict_passwords 1
\&    </Model::DB::Users>
