[Catalyst] Custom error handling

[kakimoto at tpg.com.au]

hello Tomas and everyone,

 Thank you for that.

 I got it working.


 What I also did was the in the case of an exception, I will redirect
the user back to the main page with the error shown.

I would like to share what I did.

On Root.pm->end: I passed the error message to the flash (I have
flash_to_stash turned on) because due to a redirection, the only way the
error message can be sustained is via the flash.
============


sub end : ActionClass('RenderView') {
    my ($self, $c) = @_;

    if ( scalar @{ $c->error } ) {
        $c->flash->{errors}   = $c->error;

        $c->response->redirect($c->uri_for('/'));
        $c->error(0);
    }
    return 1;
};


On my controller, Subscriptions.pm
=======================

sub _save_address : Private
{
    eval
    {
        .....
   };
   if ($@)
   {
          $c->error (' A problem occurred when saving your address.
Please try again later' );
   }
}



Using die(' A problem occurred when saving your address. Please try
again later' );, 
I would get an error message such as "Exception caught in
myApp::Controller::Subscription->_save_address" which doesn't look so
good to the users.
that's why I used $c->error.

Please tell me if it's bad practice?


thank you, everybody for your time! :)
