These should go in the tutorial?

SETTING UP A REACTION APPLICATION

Reaction applications are set up just like Catalyst:

    $ catalyst.pl MyApp
    # output ommited
    $ cd MyApp

Models

Reaction provides a reflector component which automagically maps a DBIx::Class::Schema into a set of Interface Models which can be used by Reaction to build the interface components. If you're not familiar with DBIx::Class or don't have a schema handy, now is a good time to go through DBIx::Class::Manual::Intro to get a schema set up.

It is important that your Result-objects implement the meta-protocol of Moose. One way to achive that is to do the following:

    package MyApp::Schema::Result::Bar;
    use base 'DBIx::Class';
    use Moose;
    
    has 'name' => (isa => 'Str', required => 1, rw => 1);
    
    use namespace::autoclean;
    
    __PACKAGE__->load_components(qw(Core));
    __PACKAGE__->table('bar');
    __PACKAGE__->add_columns(
        name => {
            data_type   => 'varchar',
            size        => 255,
            is_nullable => 0,
        }
    );
    __PACKAGE__->primary_key('name');
    1;
    

Once you have your schema set up like that, you can create the InferfaceModel:

    package MyApp::InterfaceModel::DBIC;

    use base 'Reaction::InterfaceModel::Object';
    use Reaction::InterfaceModel::Reflector::DBIC;

    my $reflector = Reaction::InterfaceModel::Reflector::DBIC->new;

    $reflector->reflect_schema(
         model_class  => __PACKAGE__,
         schema_class => 'MyApp::Schema',
         sources => [qw/Foo Baz/],
    );

    1;

Then you create a MyApp::Model that uses this InferfaceModel:

    package Myapp::Model::IM;
    
    use Reaction::Class;
    
    extends 'Catalyst::Model::Reaction::InterfaceModel::DBIC';

    1;
    

Controllers

Root controller

Your Reaction application must have a Root controller which inherits from Reaction::UI::Controller::Root.

    package MyApp::Controller::Root;

    use warnings;
    use strict;
    use base qw/Reaction::UI::Controller::Root/;

    __PACKAGE__->config(
        view_name => 'Site',
        window_title => 'My Reaction App',
        namespace => ''
    );

    sub base : Chained('/') PathPart('') CaptureArgs(0) {
        # do some setup for every request
        # also provides a chain root for other controllers to use
    }

    1;

Individual controllers

For each Collection(table?) in your DB, you need to create a controller

    package MyApp::Controller::Foo;

    use base 'Reaction::UI::Controller::Collection::CRUD';
    use Reaction::Class;

    __PACKAGE__->config(
      model_name => 'IM',   # This corresponds to the name of the MyApp::Model you created earlier
      collection_name => 'Foo', # Name of one of the sources in your InterfaceModel
      action => {
        base => { Chained => '/base',  # chain to the base action in the root controller
                  PathPart => 'foo' },
      },
    );

    1;
    

XX TODO

View

One of the views in your application should look something like this:

    package MyApp::View::TT;

    use Reaction::Class;

    extends 'Reaction::UI::View::TT';

    1;

    __END__;
