NAME
Catalyst::View::Component::SubInclude - Use subincludes in your Catalyst
views
VERSION
Version 0.10
SYNOPSIS
package MyApp::View::TT;
use Moose;
extends 'Catalyst::View::TT';
with 'Catalyst::View::Component::SubInclude';
__PACKAGE__->config( subinclude_plugin => 'SubRequest' );
Then, somewhere in your templates:
[% subinclude('/my/widget') %]
[% subinclude_using('SubRequest', '/page/footer') %]
DESCRIPTION
"Catalyst::View::Component::SubInclude" allows you to include content in
your templates (or, more generally, somewhere in your view's "render"
processing) which comes from another action in your application. It's
implemented as a Moose::Role, so using Moose in your view is required.
Simply put, it's a way to include the output of a Catalyst sub-request
somewhere in your page.
It's built in an extensible way so that you're free to use sub-requests,
Varnish ESI (<http://www.catalystframework.org/calendar/2008/17>) or any
other sub-include plugin you might want to implement.
STASH FUNCTIONS
This component does its magic by exporting a "subinclude" coderef entry
to the stash. This way, it's easily accessible by the templates (which
is the most common use-case).
"subinclude( $path, @args )"
This will render and return the body of the included resource (as
specified by $path) using the default subinclude plugin.
"subinclude_using( $plugin, $path, @args )"
This will render and return the body of the included resource (as
specified by $path) using the specified subinclude plugin.
The "subinclude" function above is implemented basically as a shortcut
which calls this function using the default plugin as the first
parameter.
SUBINCLUDE PLUGINS
The module comes with two subinclude plugins: SubRequest, Visit and ESI.
By default, the "SubRequest" plugin will be used. This can be changed in
the view's configuration options (either in the config file or in the
view module itself).
Configuration file example:
<View::TT>
subinclude_plugin ESI
</View::TT>
"set_subinclude_plugin( $plugin )"
This method changes the current active subinclude plugin in runtime. It
expects the plugin suffix (e.g. "ESI" or "SubRequest") or a
fully-qualified class name in the
"Catalyst::View::Component::SubInclude" namespace.
Writing plugins
If writing your own plugin, keep in kind plugins are required to
implement a class method "generate_subinclude" with the following
signature:
sub generate_subinclude {
my ($class, $c, @args) = @_;
}
The default plugin is stored in the "subinclude_plugin" which can be
changed in runtime. It expects a fully qualified class name.
