Try this:
sub post_chain_root : Chained('/') CaptureArgs(0) {
my ($self, $c) = @_;
foreach my $action (@{$c->action->chain}) {
my $role = $action->attributes->{RequiresRole}[0];
next unless $role;
## test role here...
}
}
That's a bit of code that you can put in the root of a Chained chain and do
something like
sub create_new_post : RequiresRole('can_post') {
# ...
}
HTH.
