The easiest way to do this is with a component. Here's how to set this
up -- names of classes, methods and templates are up to you :-)

1) In your 'ticker' package, create an entry in conf/action.perl for
your component. This is how OI knows how to connect your component call
with Perl code:

 $action = {
    ticker_embed => { class  => 'OpenInteract::Handler::Ticker',
                      method => 'show_embedded' },
    ...
 };

2) Create a method OpenInteract::Handler::Ticker->show_embeded:

 sub show_embedded {
    my ( $class, $params ) = @_;
    my $R = OpenInteract::Request->instance;
    my $ticker_entries = $R->ticker->fetch_group;
    return $R->template->handler( {}, { ticker => $ticker_entries },
                                  { name => 'ticker::show_entries' } );
 }

3) Create a template 'show_entries':

 <p>Ticker Entries:<br>
 [% FOREACH entry = ticker %]
    [% entry.name %] --> [% entry.value %]<br>
 [% END %]

4) Call the component:

  [% OI.comp( 'ticker_embed' ) %]

You can pass parameters from the component call to the perl code also:

  [% OI.comp( 'ticker_embed', num_entries = 5 ) %]

These parameters get put into the \%params argument passed to your
handler.

Hope this helps,

Chris
