NAME CGI::Application::Plugin::Forward - Pass control from one run mode to another VERSION Version 1.01 SYNOPSIS use base 'CGI::Application'; use CGI::Application::Plugin::Forward; sub setup { my $self = shift; $self->run_modes([qw( start second_runmode )]); } sub start { my $self = shift; return $self->forward('second_runmode'); } sub second_runmode { my $self = shift; my $rm = $self->get_current_runmode; # 'second_runmode' } DESCRIPTION The forward method passes control to another run mode and returns its output. This is equivalent to calling "$self->$other_runmode", except that CGI::Application's internal value of the current run mode is updated. This means that calling "$self->get_current_runmode" after calling "forward" will return the name of the new run mode. This is useful for modules that depend on the name of the current run mode such as CGI::Application::Plugin::AnyTemplate. For example, here's how to pass control to a run mode named "other_action" from "start" while updating the value of "current_run_mode": sub setup { my $self = shift; $self->run_modes({ start => 'start', other_action => 'other_method', }); } sub start { my $self = shift; return $self->forward('other_action'); } sub other_method { my $self = shift; my $rm = $self->get_current_runmode; # 'other_action' } Note that forward accepts the *name* of the run mode (in this case *'other_action'*), which might not be the same as the name of the method that handles the run mode (in this case *'other_method'*) You can still call "$self->other_method" directly, but "current_run_mode" will not be updated: sub setup { my $self = shift; $self->run_modes({ start => 'start', other_action => 'other_method', }); } sub start { my $self = shift; return $self->other_method; } sub other_method { my $self = shift; my $rm = $self->get_current_runmode; # 'start' } Forward will work with coderef-based runmodes as well: sub setup { my $self = shift; $self->run_modes({ start => 'start', anon_action => sub { my $self = shift; my $rm = $self->get_current_runmode; # 'anon_action' }, }); } sub start { my $self = shift; return $self->forward('anon_action'); } METHODS forward Runs another run mode passing any parameters you supply. Returns the output of the new run mode. return $self->forward('run_mode_name', @run_mode_params); AUTHOR Michael Graham, "" BUGS Please report any bugs or feature requests to "bug-cgi-application-plugin-forward@rt.cpan.org", or through the web interface at .
