35 C<Catalyst::View::Component::SubInclude> allows you to include content in your
36 templates (or, more generally, somewhere in your view's C<render> processing)
37 which comes from another action in your application. It's implemented as a
38 L<Moose::Role|Moose::Role>, so using L<Moose|Moose> in your view is required.
40 Simply put, it's a way to include the output of a Catalyst sub-request somewhere
43 It's built in an extensible way so that you're free to use sub-requests, Varnish
44 ESI (L<http://www.catalystframework.org/calendar/2008/17>) or any other
45 sub-include plugin you might want to implement. An LWP plugin seems useful and
46 might be developed in the future.
50 This component does its magic by exporting a C<subinclude> coderef entry to the
51 stash. This way, it's easily accessible by the templates (which is the most

61 The module comes with two subinclude plugins:
62 L<SubRequest|Catalyst::Plugin::View::Component::SubRequest> and
63 L<ESI|Catalyst::Plugin::View::Component::ESI>.
65 By default, the SubRequest plugin will be used. This can be changed in the
66 view's configuration options (either in the config file or in the view module
69 Configuration file example:
75 If writing your own plugin, keep in kind plugins are required to implement a
76 class method C<generate_subinclude> with the following signature:
78 sub generate_subinclude {
79 my ($class, $c, @args) = @_;
84 has 'subinclude_plugin' => (
93 my $self = $class->$next( @_ );
95 my $subinclude_plugin = $self->config->{subinclude_plugin} || 'SubRequest';
96 my $subinclude_class = __PACKAGE__ . '::' . $subinclude_plugin;
98 eval "require $subinclude_class";
99 croak "Error requiring $subinclude_class: $@" if $@;
101 $self->subinclude_plugin( $subinclude_class );
106 around 'render' => sub {
108 my ($self, $c, @args) = @_;
110 $c->stash->{subinclude} = sub {
111 $self->subinclude_plugin->generate_subinclude( $c, @_ );
