Well, my main thing is that I've got issues with bridges and waypoints,
for example I use a bridge to see if a user is authenticated and if they
are, it pulls up a wad of information from MongoDB using Mango - the
only issue I have is that a bridge must return a value to indicate
whether the rest of the chain needs to be handled. Either I do it wrong,
or I can't seem to find away to do this in a non-blocking manner, e.g.
if I'm in a Mango find_one callback, I can't say "return 1" and have
that be the return value for the bridge.
Right now I kludge it together with the around_action hook but I doubt
that's what it was meant for, at least, it seems to be a rather
sledgehammer-ish solution. I'd love to see a bridge_nb where I'd be able
to do stuff like:
sub bridge {
my $self = shift;
my $next = shift;
$self->model('foo.bar')->find_one({ ... } => sub {
my ($coll, $err, $doc) = (@_);
if($doc->{foo}) {
$next->continue;
} else {
$next->stop;
}
});
}
Like I said, maybe it's possible already, I couldn't figure it out so I
may be talking up the wrong tree here :D
Basically a way to explicitly request that the dispatcher lets bridges,
waypoints, and other such things do it's thing in this fashion would let
me deal with it in a nicer way than messing with around_action or even
around_dispatch since it just feels too brutal for something like this.
