Re: [Mojolicious] Pg PubSub listen from a model

[John]

I figured out what I was doing wrong.   It was with the sending of 
notifications.   The condition was not being hit to send the message.  I 
did the basic debugging I should have done before contacting the mailing 
list.

That notify is similar on what is in the base class:

Model code that attempts to receive the pubsub messages:

Hello,

 From my model I want to listen for Pg PubSub messages. I am passing
the helper "pg" into the model as a param after creating it:

    $self->helper( pg => sub { state $pg = Mojo::Pg->new(
$config->{pg}
) } );

How do I listen for messages?  This compiles but doesn't do
anything as
far as I can see:

 $self->pg->pubsub->listen(location_msg => sub {
 my ($pubsub, $payload) = @_;
 $self->log->debug('location: ' . Dumper($payload));
 });

Do I need to create a Mojo loop of some sort in my model?
