A new instance is created at application time, so any consumed required
attributes, coercions and modifiers will work.
-Roles are applied before setup, schema and connection are set, and have a chance
-to modify C<connect_info>.
+Traits are applied at L<Catalyst::Component/COMPONENT> time using
+L<CatalystX::Component::Traits>.
-C<ref $self> will not be what you expect.
+C<ref $self> will be an anon class if any traits are applied, C<<
+$self->_original_class_name >> will be the original class.
-WARNING: you cannot modify C<new>, modify C<setup> instead.

-=item storage_type
+=head2 storage_type
Allows the use of a different C<storage_type> than what is set in your
C<schema_class> (which in turn defaults to C<::DBI> if not set in current
L<DBIx::Class>). Completely optional, and probably unnecessary for most
people until other storage backends become available for L<DBIx::Class>.

+=head1 ATTRIBUTES

+The keys you pass in the model configuration are available as attributes.

+Other attributes available:

+Your connect_info args normalized to hashref form (with dsn/user/password.) See

+
+=head2 model_name
+
+The model name L<Catalyst> uses to resolve this model, the part after
+C<::Model::> or C<::M::> in your class name. E.g. if your class name is
+C<MyApp::Model::DB> the L</model_name> will be C<DB>.
+
+=head2 _default_cursor_class
+
+What to reset your L<DBIx::Class::Storage::DBI/cursor_class> to if a custom one
+doesn't work out. Defaults to L<DBIx::Class::Storage::DBI::Cursor>.
+
+=head1 ATTRIBUTES FROM L<MooseX::Traits::Pluggable>
+
+=head2 _original_class_name
+
+The class name of your model before any L</traits> are applied. E.g.
+C<MyApp::Model::DB>.
+
+=head2 _traits
+
+Unresolved arrayref of traits passed in the config.
+
+=head2 _resolved_traits
+
+Traits you used resolved to full class names.
=head1 METHODS
-=over 4
+Methods not listed here are delegated to the connected schema used by the model
+instance, so the following are equivalent:
-=item new
+ $c->model('DB')->schema->my_accessor('foo');
+ # or
+ $c->model('DB')->my_accessor('foo');
+
+Methods on the model take precedence over schema methods.
+
+=head2 new
Instantiates the Model based on the above-documented ->config parameters.
The only required parameter is C<schema_class>. C<connect_info> is
required in the case that C<schema_class> does not already have connection
information defined for it.
-=item schema
+=head2 schema
Accessor which returns the connected schema being used by the this model.
There are direct shortcuts on the model class itself for
schema->resultset, schema->source, and schema->class.
-=item composed_schema
+=head2 composed_schema
Accessor which returns the composed schema, which has no connection info,
which was used in constructing the C<schema> above. Useful for creating
new connections based on the same schema/model. There are direct shortcuts
from the model object for composed_schema->clone and composed_schema->connect
-=item clone
+=head2 clone
Shortcut for ->composed_schema->clone
-=item connect
+=head2 connect
Shortcut for ->composed_schema->connect
-=item source
+=head2 source
Shortcut for ->schema->source
-=item class
+=head2 class
Shortcut for ->schema->class
-=item resultset
+=head2 resultset
Shortcut for ->schema->resultset
-=item storage
+=head2 storage
Provides an accessor for the connected schema's storage object.
Used often for debugging and controlling transactions.
