This is pretty simple. Actions work just like the normal dispatch
attributes you are used to, like Local or Private:
- sub Hello :Local :ActionClass('SayBefore') {
- $c->res->output( 'Hello '.$c->stash->{what} );
- }
+ sub Hello :Local :ActionClass('SayBefore') {
+ $c->res->output( 'Hello '.$c->stash->{what} );
+ }
In this example, we expect the SayBefore action to magically populate
stash with something relevant before C<Hello> is run. In the next
L<Catalyst::Action> as a base class and decorate the C<execute> call in
the Action class:
- package Catalyst::Action::MyAction;
- use Moose;
- use namespace::autoclean;
+ package Catalyst::Action::MyAction;
+ use Moose;
+ use namespace::autoclean;
- extends 'Catalyst::Action';
+ extends 'Catalyst::Action';
- before 'execute' => sub {
- my ( $self, $controller, $c, $test ) = @_;
- $c->stash->{what} = 'world';
- };
+ before 'execute' => sub {
+ my ( $self, $controller, $c, $test ) = @_;
+ $c->stash->{what} = 'world';
+ };
- after 'execute' => sub {
- my ( $self, $controller, $c, $test ) = @_;
- $c->stash->{foo} = 'bar';
- };
+ after 'execute' => sub {
+ my ( $self, $controller, $c, $test ) = @_;
+ $c->stash->{foo} = 'bar';
+ };
- __PACKAGE__->meta->make_immutable;
+ __PACKAGE__->meta->make_immutable;
Pretty simple, huh?
The solution to this is to use L<Catalyst::Controller::ActionRole>, which
would make the example above look like this:
- package Catalyst::ActionRole::MyActionRole;
- use Moose::Role;
+ package Catalyst::ActionRole::MyActionRole;
+ use Moose::Role;
- before 'execute' => sub {
- my ( $self, $controller, $c, $test ) = @_;
- $c->stash->{what} = 'world';
- };
+ before 'execute' => sub {
+ my ( $self, $controller, $c, $test ) = @_;
+ $c->stash->{what} = 'world';
+ };
- after 'execute' => sub {
- my ( $self, $controller, $c, $test ) = @_;
- $c->stash->{foo} = 'bar';
- };
+ after 'execute' => sub {
+ my ( $self, $controller, $c, $test ) = @_;
+ $c->stash->{foo} = 'bar';
+ };
- 1;
+ 1;
and this would be used in a controller like this:
- package MyApp::Controller::Foo;
- use Moose;
- use namespace::autoclean;
- BEGIN { extends 'Catalyst::Controller::ActionRole'; }
+ package MyApp::Controller::Foo;
+ use Moose;
+ use namespace::autoclean;
+ BEGIN { extends 'Catalyst::Controller::ActionRole'; }
- sub foo : Does('MyActionRole') {
- my ($self, $c) = @_;
- }
+ sub foo : Does('MyActionRole') {
+ my ($self, $c) = @_;
+ }

=head3 Using authentication in a testing environment
Also, it's important to note that if you restrict access to "/" then
C<end>, C<default>, etc. will also be restricted.
- MyApp->acl_allow_root_internals;
+ MyApp->acl_allow_root_internals;
will create rules that permit access to C<end>, C<begin>, and C<auto> in the
root of your app (but not in any other controller).
Assume our Controller module starts with the following package declaration:
- package MyApp::Controller::Buckets;
+ package MyApp::Controller::Buckets;
and we are running our application on localhost, port 3000 (the test
server default).
controller namespace, an absolute path will represent an exact
matching URL.
- sub my_handles : Path('handles') { .. }
+ sub my_handles : Path('handles') { .. }
becomes
- http://localhost:3000/buckets/handles
+ http://localhost:3000/buckets/handles
and
- sub my_handles : Path('/handles') { .. }
+ sub my_handles : Path('/handles') { .. }
becomes
- http://localhost:3000/handles
+ http://localhost:3000/handles
See also: L<Catalyst::DispatchType::Path>
name of the action is matched in the URL. The namespaces created by
the name of the controller package is always part of the URL.
- sub my_handles : Local { .. }
+ sub my_handles : Local { .. }
becomes
- http://localhost:3000/buckets/my_handles
+ http://localhost:3000/buckets/my_handles
=item Global
A Global attribute is similar to a Local attribute, except that the
namespace of the controller is ignored, and matching starts at root.
- sub my_handles : Global { .. }
+ sub my_handles : Global { .. }
becomes
- http://localhost:3000/my_handles
+ http://localhost:3000/my_handles
=item Regex
sounds like. This one takes a regular expression, and matches starting
from root. These differ from the rest as they can match multiple URLs.
- sub my_handles : Regex('^handles') { .. }
+ sub my_handles : Regex('^handles') { .. }
matches
- http://localhost:3000/handles
+ http://localhost:3000/handles
and
- http://localhost:3000/handles_and_other_parts
+ http://localhost:3000/handles_and_other_parts
etc.
A LocalRegex is similar to a Regex, except it only matches below the current
controller namespace.
- sub my_handles : LocalRegex(^handles') { .. }
+ sub my_handles : LocalRegex(^handles') { .. }
matches
- http://localhost:3000/buckets/handles
+ http://localhost:3000/buckets/handles
and
- http://localhost:3000/buckets/handles_and_other_parts
+ http://localhost:3000/buckets/handles_and_other_parts
etc.
to create your own internal actions, which can be forwarded to, but
won't be matched as URLs.
- sub my_handles : Private { .. }
+ sub my_handles : Private { .. }
becomes nothing at all..
to find out where it was the user was trying to go, you can look in
the request object using C<< $c->req->path >>.
- sub default :Path { .. }
+ sub default :Path { .. }
works for all unknown URLs, in this controller namespace, or every one
if put directly into MyApp.pm.
actions are defined, then index will be used instead of default and
Path.
- sub index :Path :Args(0) { .. }
+ sub index :Path :Args(0) { .. }
becomes
- http://localhost:3000/buckets
+ http://localhost:3000/buckets
=item begin
app. A single begin action is called, its always the one most relevant
to the current namespace.
- sub begin : Private { .. }
+ sub begin : Private { .. }
is called once when
- http://localhost:3000/bucket/(anything)?
+ http://localhost:3000/bucket/(anything)?
is visited.
always the one most relevant to the current namespace.
- sub end : Private { .. }
+ sub end : Private { .. }
is called once after any actions when
- http://localhost:3000/bucket/(anything)?
+ http://localhost:3000/bucket/(anything)?
is visited.
called. (In contrast, only one of the begin/end/default actions will
be called, the relevant one).
- package MyApp::Controller::Root;
- sub auto : Private { .. }
+ package MyApp::Controller::Root;
+ sub auto : Private { .. }
and
will both be called when visiting
- http://localhost:3000/bucket/(anything)?

the Catalyst Request object:

- $c->forward('/wherever', [qw/arg1 arg2 arg3/]);

+ $c->forward('/wherever', [qw/arg1 arg2 arg3/]);
- # pre-5.30
- $c->req->args([qw/arg1 arg2 arg3/]);
- $c->forward('/wherever');
+ # pre-5.30
+ $c->req->args([qw/arg1 arg2 arg3/]);
+ $c->forward('/wherever');

}
Using the plugin is as simple as setting your use line in MyApp.pm to include:
- use Catalyst qw/Static::Simple/;
+ use Catalyst qw/Static::Simple/;
and already files will be served.
You may of course want to change the default locations, and make
Static::Simple look somewhere else, this is as easy as:
- MyApp->config(
- static => {
- include_path => [
- MyApp->path_to('/'),
- '/path/to/my/files',
- ],
- },
- );
+ MyApp->config(
+ static => {
+ include_path => [
+ MyApp->path_to('/'),
+ '/path/to/my/files',
+ ],
+ },
+ );
When you override include_path, it will not automatically append the
normal root path, so you need to add it yourself if you still want
If you want to force some directories to be only static, you can set
them using paths relative to the root dir, or regular expressions:
- MyApp->config(
- static => {
- dirs => [
- 'static',
- qr/^(images|css)/,
- ],
- },
- );
+ MyApp->config(
+ static => {
+ dirs => [
+ 'static',
+ qr/^(images|css)/,
+ ],
+ },
+ );
=item File extensions
be processed by Catalyst): B<tmpl, tt, tt2, html, xhtml>. This list can
be replaced easily:
- MyApp->config(
+ MyApp->config(
static => {
ignore_extensions => [
qw/tmpl tt tt2 html xhtml/
],
},
- );
+ );
=item Ignoring directories
Entire directories can be ignored. If used with include_path,
directories relative to the include_path dirs will also be ignored:
- MyApp->config( static => {
+ MyApp->config( static => {
ignore_dirs => [ qw/tmpl css/ ],
- });
+ });
=back
my ( $self, $c ) = @_;
$c->forward( 'MyApp::View::TT' )
- unless ( $c->res->body || !$c->stash->{template} );
+ unless ( $c->res->body || !$c->stash->{template} );
}
This code will only forward to the view if a template has been
the same terms as Perl itself.

=head1 OVERVIEW
This is B<Chapter 9 of 10> for the Catalyst tutorial.
...
<p>
- HTML::FormHandler:
- <a href="[% c.uri_for(c.controller.action_for('create')) %]">Create</a>
+ HTML::FormHandler:
+ <a href="[% c.uri_for(c.controller.action_for('create')) %]">Create</a>
</p>
This adds a new link to the bottom of the book list page that we can
"Delete" link to use the FormHandler edit method:
<td>
- [% # Add a link to delete a book %]
- <a href="[% c.uri_for(c.controller.action_for('delete'), [book.id]) %]">Delete</a>
- [% # Add a link to edit a book %]
- <a href="[% c.uri_for(c.controller.action_for('edit'), [book.id]) %]">Edit</a>
+ [% # Add a link to delete a book %]
+ <a href="[% c.uri_for(c.controller.action_for('delete'), [book.id]) %]">Delete</a>
+ [% # Add a link to edit a book %]
+ <a href="[% c.uri_for(c.controller.action_for('edit'), [book.id]) %]">Edit</a>
