Ha okay, will try to post everything relevant without putting too much in that you don't need (I'm a little worried that you'll come back and say my code is totally awful!) Bear in mind I've cut out a lot of the error checking that's irrelevant to this.

So I have my controllers set up something like this:

=head2 base Chain base for getting the club ID and checking it. Matches /clubs/* =cut sub base :Chained("/") :PathPart("clubs") :CaptureArgs(1) { my ( $self, $c, $id_or_key ) = @_; # Load the messages $c->load_status_msgs; my $club = $c->model("DB::Club")->find_id_or_url_key( $id_or_key ); if ( defined($club) ) { # Club found, stash it, then stash the name / view URL in the brea +dcrumbs section of our stash $c->stash({ club => $club, breadcrumbs => { object => { label => $club->full_name, link => $c->uri_for_action("/clubs/view", [$club->url_key]) +, }, }, }); } else { # 404 $c->detach( "TopTable::Controller::Root", "default" ); return; } } =head2 view Chained to the base class; all this does is check we're authorised to +view clubs, then the more relevant funcionality is in methods chained + from this. =cut sub view :Chained("base") :PathPart("") :CaptureArgs(0) { my ( $self, $c ) = @_; # Check that we are authorised to view clubs $c->forward( "TopTable::Controller::Users", "check_authorisation", [ +"club_view", "view clubs", 1] ); $c->forward( "TopTable::Controller::Users", "check_authorisation", [ + [ qw( club_edit club_delete team_view team_create ) ], "edit clubs", + 0] ); } =head2 Get and stash the current season (or last complete one if it doesn't e +xist) for the team view page. End of chain for /clubs/* =cut =head2 Get and stash the current season (or last complete one if it doesn't e +xist) for the team view page. End of chain for /clubs/* =cut sub view_current_season :Chained("view") :PathPart("") :Args(0) { my ( $self, $c ) = @_; my $club = $c->stash->{club}; # Try to find the current season (or the last completed season if th +ere is no current season) my $season = $c->model("DB::Season")->get_current; # More season stuff # Finalise the view routine $c->detach("view_finalise"); } =head2 view_specific_season View a club only with teams for a specific season. Matches /clubs/*/s +easons/* (End of chain) =cut sub view_specific_season :Chained("view") :PathPart("seasons") :Args(1 +) { my ( $self, $c, $season_id_or_url_key ) = @_; my $club = $c->stash->{club}; # Validate the passed season ID my $season = $c->model("DB::Season")->find_id_or_url_key( $season_id +_or_url_key ); if ( defined($season) ) { # More season stuff # Append the season on to the object for breadcrumbs - this is for + using in sprintf for our text labels $c->stash->{breadcrumbs}{replace_text} = $season->name; } # Finalise the view routine $c->detach("view_finalise"); } sub view_finalise :Private { # Irrelevant to this }

My breadcrumbs code is:

# Get the action for the current request and join it on to the names +pace (unless they match, as that means we'll get multiples where we d +on't want it; if the action has a slash in it, we won't join either) my $action = $c->request->action; $action = join("/", $c->namespace, $action) unless $action eq $c-> +namespace or $action =~ m#/#; my @paths = split("/", $action); # This array will hold the breadcrumbs bits in reverse order (we w +ill reverse it when we stash it) my @breadcrumbs = (); my $i = 0; # Counter to tell if we're on the first bit - if we are +, don't link it, as that's the current page while( my $label = pop(@paths) ) { # Skip if we're hiding indices and this is an index next if $label eq "index" and $c->config->{breadcrumbs}{hide_ind +ex}; # The path is all of the @path elements we haven't popped off so + far, plus the current path elemtn (currently in $label) # joined with slashes. my $path = join( "/", @paths, $label ); # Build the label $label = $c->forward( "breadcrumbs_label_for", [$path, $label] ) +; # Now that we have the label for this path, we can get rid of th +e path if this is the first iteration, so we don't link to it $path = "" unless $i; # Push the path and label on to our breadcrumbs array if we have + a label (if it's blank, assume we don't want to display it) push(@breadcrumbs, { path => $path, label => $label, }) if $label; unless ( $i ) { # We need to set up the object after the first iteration so th +at we can have something like 'path > object > action (view, edit, et +c)' if ( exists( $c->stash->{breadcrumbs}{object} ) ) { my $object = $c->stash->{breadcrumbs}{object}; # Check if we have a link and we're not currrently viewing t +he object (no point linking the object if we're already viewing it) if ( exists( $object->{link} ) and $c->request->action !~ /( +view|view_current_season|view_specific_season)$/ ) { # Push the path and label on to our breadcrumbs array push(@breadcrumbs, { path => $object->{link}, label => $object->{label}, }); } else { # Push label only on to our breadcrumbs array push(@breadcrumbs, { label => $object->{label}, }); } } } $i++; # Increment the counter } # Add the home element if we need unless ( $c->config->{breadcrumbs}{hide_home} ) { my $label = $c->forward( "breadcrumbs_label_for", [qw( / home ) +]); push(@breadcrumbs, { path => "/", label => $label }); } =head2 breadcrumbs_label_for Generate labels for specific paths in the breadcrumbs. =cut breadcrumbs_label_for sub breadcrumbs_label_for :Private { my ( $self, $c, $path, $label ) = @_; # If we have a customised label for this path, return it if ( exists( $c->config->{breadcrumbs}{labels}{$path} ) ) { if ( exists( $c->stash->{breadcrumbs}{replace_text} ) ) { # Replacement text, sprintf it # First check if the replacement text is an array, if not, make +it one - this makes it easier to pass in both and not care which is w +hich from now on $c->stash->{breadcrumbs}{replace_text} = [ $c->stash->{breadcrum +bs}{replace_text} ] if ref( $c->stash->{breadcrumbs}{replace_text} ) +ne "ARRAY"; # Now return the sprintf'd version of the label return sprintf( $c->config->{breadcrumbs}{labels}{$path}, @{ $c- +>stash->{breadcrumbs}{replace_text} } ); } else { # No replacement text, just return it return $c->config->{breadcrumbs}{labels}{$path}; } } # If there's no label specified, we use the path. Replace underscor +es with spaces and convert the first following character to uppercase $label =~ s/_(.)/" " . uc($1)/eg; # Return the value with the first character converted to upper-case +(unless we've specified all lower-case) return !$c->config->{breadcrumbs}{lowercase} ? ucfirst($label) : lc( +$label); }

Hope all this makes sense - genuinely a little worried about showing my code to genuine Perl gurus...! Eventually I think I want to get to something like this:

controller > object (looked up from base method) > action > 'Seasons' > season
controller > object > action
etc.

My plan was to split the action up into its individual parts and hopefully do it that way, but I'm getting the previously stated error when I try and do this.
