Setup a model that has comments: 

  package App::Model::Fooble;
  use Jifty::DBI::Schema;
  use App::Record schema {
      column scribble => type is 'text';
      column wobble => type is 'int';
  };
  use Jifty::Plugin::Comment::Mixin::Model::Commented;
  sub allow_owner_update_delete {
      my $self = shift;
      my ($right, %args) = @_;
      if ($right eq 'create') {
          return 'allow' ;#if $self->current_user->id;
      }
      if ($right eq 'update' || $right eq 'delete') {
          return 'allow' if $self->current_user->id;
      }
      if ($right eq 'read') {
          return 'allow';
      }
      return 'deny';
  };
  App::Model::FoobleComment->add_trigger( name => 'before_access', callback => \&allow_owner_update_delete);
  App::Model::Comment->add_trigger( name => 'before_access', callback => \&allow_owner_update_delete);

Setup a view for creating, viewing, and managing the comments: 

  # assuming $fooble here isa App::Action::UpdateFooble object
  template 'fooble/view' => page {
      my $fooble = get 'fooble';
      render_action $fooble, undef, { render_mode => 'read' };
      render_region
          name     => 'fooble-comments',
          path     => '__comment/list_and_add',
          defaults => { 
              comment_upon  => $fooble->record->for_commenting,
              initial_title => 'Re: '.substr($fooble->scribble, 0, 20).'...',
          },
          ;
  };

DESCRIPTION

This plugin allows you to attach comments to any model. You do this using the three steps listed in the synopsis. For variations on these steps, see the other classes that handle the individual parts.

COMMENTED RECORDS

To set up a commented model, you will need to do the following:
1 Add ths plugin to your project by modifying your config.yml.
1 Add the Jifty::Plugin::Comment::Mixin::Model::Commented mixin to the model or models that you want to have comments attached to. See that class for details on how it works. You may also want to examine Jifty::Plugin::Comment::Model::Comment on how to customize that class for your application.
1 Create a view that appends a comment editor to your edit form (or on a separate page or wherever you feel like comments work best in your application). You should be able to use these views from either Template::Declare or HTML::Mason templates. See Jifty::Plugin::Comment::View for additional details on what views are available.

METHODS

init

Called during initialization. This will setup the Net::Akismet object if it is configured and available.

akismet

This returns an instance of Net::Akismet that is used to check to see if a new comment posted contains spam. No such checking is performed if this returns "undef", which indicates that "Net::Akismet" is unavailable, wasn't configured, or there was an error configuring it (e.g., the Akismet server was unavailable during Jifty startup).

scrubber

This returns an instance of HTML::Scrubber that is used to clean up HTML submitted in comments.

TO DO

Right now the module depends directly upon HTML::Scrubber to do the work of cleaning up the text. You might want to use something else to do this. It also provides no mechanism for customizing any other aspect of the formatting. For example, your application might want to use Markdown, or BBCode, or just turn line breaks in the BR-tags, or anything else to format the comment text.

In the future, I'd like to consider something like Text::Pipe or a similar API to allow these formats to be customized more easily.
