rest of your application.
-=head3 $c->uri_for()
+=head3 C<< $c->uri_for() >>
One of my favorite things about Catalyst is the ability to move an
application around without having to worry that everything is going to
break. One of the areas that used to be a problem was with the http
links in your template files. For example, suppose you have an
-application installed at http://www.domain.com/Calendar. The links point
-to "/Calendar", "/Calendar/2005", "/Calendar/2005/10", etc. If you move
-the application to be at http://www.mydomain.com/Tools/Calendar, then
+application installed at C<http://www.domain.com/Calendar>. The links point
+to "C</Calendar>", "C</Calendar/2005>", "C</Calendar/2005/10>", etc. If you move
+the application to be at C<http://www.mydomain.com/Tools/Calendar>, then
all of those links will suddenly break.
-That's where $c->uri_for() comes in. This function will merge its
+That's where C<< $c->uri_for() >> comes in. This function will merge its
parameters with either the base location for the app, or its current
namespace. Let's take a look at a couple of examples.
Although the parameter starts with a forward slash, this is relative
to the application root, not the webserver root. This is important to
remember. So, if your application is installed at
-http://www.domain.com/Calendar, then the link would be
-http://www.mydomain.com/Calendar/Login. If you move your application
+C<http://www.domain.com/Calendar>, then the link would be
+C<http://www.mydomain.com/Calendar/Login>. If you move your application
to a different domain or path, then that link will still be correct.
Likewise,
The first parameter does NOT have a forward slash, and so it will be
relative to the current namespace. If the application is installed at
-http://www.domain.com/Calendar. and if the template is called from
-MyApp::Controller::Display, then the link would become
-http://www.domain.com/Calendar/Display/2005/10/24.
+C<http://www.domain.com/Calendar>. and if the template is called from
+C<MyApp::Controller::Display>, then the link would become
+C<http://www.domain.com/Calendar/Display/2005/10/24>.
If you want to link to a parent uri of your current namespace you can
-prefix the arguments with multiple '../':
+prefix the arguments with multiple 'C<../>':
<a href="[% c.uri_for('../../view', stashed_object.id) %]">User view</a>
Once again, this allows you to move your application around without
having to worry about broken links. But there's something else, as
-well. Since the links are generated by uri_for, you can use the same

template file by several different controllers, and each controller

the normal view action first to get the objects, then handle the output
differently.

-
- sub rss : Local {
- my ($self,$c) = @_;
- $c->forward('view');
- $c->stash->{template}='rss.tt';
- }
-
-Then you need a template. Here's the one from Agave:

A Global attribute is similar to a Local attribute, except that the
namespace of the controller is ignored, and matching starts at root.

+ 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

And in the controller:
$c->stash->{template} = 'file_upload.html';
}
-C<for my $field ($c-E<gt>req->upload)> loops automatically over all file
+C<< for my $field ($c->req->upload) >> loops automatically over all file
input fields and gets input names. After that is basic file saving code,
just like in single file upload.
Notice: C<die>ing might not be what you want to do, when an error
occurs, but it works as an example. A better idea would be to store
-error C<$!> in $c->stash->{error} and show a custom error template
+error C<$!> in C<< $c->stash->{error} >> and show a custom error template
displaying this message.
For more information about uploads and usable methods look at
C<forward>; in earlier versions, you can manually set the arguments in
the Catalyst Request object:
- # version 5.30 and later:
- $c->forward('/wherever', [qw/arg1 arg2 arg3/]);
+ # version 5.30 and later:
+ $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');
(See the L<Catalyst::Manual::Intro> Flow_Control section for more
information on passing arguments via C<forward>.)

-=head1 Deployment
-
-The recipes below describe aspects of the deployment process,
-including web server engines and tips to improve application efficiency.
-
-=head2 mod_perl Deployment
-
-mod_perl is the best solution for many applications, but we'll list some pros
-and cons so you can decide for yourself. The other production deployment
-option is FastCGI, for which see below.
-
-=head3 Pros
-
-=head4 Speed
-
-mod_perl is very fast and your app will benefit from being loaded in memory
-within each Apache process.
-
-=head4 Shared memory for multiple apps
-
-If you need to run several Catalyst apps on the same server, mod_perl will
-share the memory for common modules.
-
-=head3 Cons
-
-=head4 Memory usage
-
-Since your application is fully loaded in memory, every Apache process will
-be rather large. This means a large Apache process will be tied up while
-serving static files, large files, or dealing with slow clients. For this
-reason, it is best to run a two-tiered web architecture with a lightweight
-frontend server passing dynamic requests to a large backend mod_perl
-server.
-
-=head4 Reloading
-
-Any changes made to the core code of your app require a full Apache restart.
-Catalyst does not support Apache::Reload or StatINC. This is another good
-reason to run a frontend web server where you can set up an
-C<ErrorDocument 502> page to report that your app is down for maintenance.
-
-=head4 Cannot run multiple versions of the same app
-
-It is not possible to run two different versions of the same application in
-the same Apache instance because the namespaces will collide.
-
-=head4 Setup
-
-Now that we have that out of the way, let's talk about setting up mod_perl
-to run a Catalyst app.
-
-=head4 1. Install Catalyst::Engine::Apache
-
-You should install the latest versions of both Catalyst and
-Catalyst::Engine::Apache. The Apache engines were separated from the
-Catalyst core in version 5.50 to allow for updates to the engine without
-requiring a new Catalyst release.
-
-=head4 2. Install Apache with mod_perl
-
-Both Apache 1.3 and Apache 2 are supported, although Apache 2 is highly
-recommended. With Apache 2, make sure you are using the prefork MPM and not
-the worker MPM. The reason for this is that many Perl modules are not
-thread-safe and may have problems running within the threaded worker
-environment. Catalyst is thread-safe however, so if you know what you're
-doing, you may be able to run using worker.
-
-In Debian, the following commands should get you going.
-
- apt-get install apache2-mpm-prefork
- apt-get install libapache2-mod-perl2
-
-=head4 3. Configure your application
-
-Every Catalyst application will automagically become a mod_perl handler
-when run within mod_perl. This makes the configuration extremely easy.
-Here is a basic Apache 2 configuration.
-
- PerlSwitches -I/var/www/MyApp/lib
- PerlModule MyApp
-
- <Location />
- SetHandler modperl
- PerlResponseHandler MyApp
- </Location>
-
-The most important line here is C<PerlModule MyApp>. This causes mod_perl
-to preload your entire application into shared memory, including all of your
-controller, model, and view classes and configuration. If you have -Debug
-mode enabled, you will see the startup output scroll by when you first
-start Apache.
-
-For an example Apache 1.3 configuration, please see the documentation for
-L<Catalyst::Engine::Apache::MP13>.
-
-=head3 Test It
-
-That's it, your app is now a full-fledged mod_perl application! Try it out
-by going to http://your.server.com/.
-
-=head3 Other Options
-
-=head4 Non-root location
-
-You may not always want to run your app at the root of your server or virtual
-host. In this case, it's a simple change to run at any non-root location
-of your choice.
-
- <Location /myapp>
- SetHandler modperl
- PerlResponseHandler MyApp
- </Location>
-
-When running this way, it is best to make use of the C<uri_for> method in
-Catalyst for constructing correct links.
-
-=head4 Static file handling
-
-Static files can be served directly by Apache for a performance boost.
-
- DocumentRoot /var/www/MyApp/root
- <Location /static>
- SetHandler default-handler
- </Location>
-
-This will let all files within root/static be handled directly by Apache. In
-a two-tiered setup, the frontend server should handle static files.
-The configuration to do this on the frontend will vary.
-
-The same is accomplished in lighttpd with the following snippet:
-
- $HTTP["url"] !~ "^/(?:img/|static/|css/|favicon.ico$)" {
- fastcgi.server = (
- "" => (
- "MyApp" => (
- "socket" => "/tmp/myapp.socket",
- "check-local" => "disable",
- )
- )
- )
+ my ( $self, $c ) = @_;
+ $c->forward('render');
+ # do stuff here
}
-Which serves everything in the img, static, css directories
-statically, as well as the favicon file.
-
-Note the path of the application needs to be stated explicitly in the
-web server configuration for both these recipes.
-
-=head2 Catalyst on shared hosting
-
-So, you want to put your Catalyst app out there for the whole world to
-see, but you don't want to break the bank. There is an answer - if you
-can get shared hosting with FastCGI and a shell, you can install your
-Catalyst app in a local directory on your shared host. First, run
-
- perl -MCPAN -e shell
-
-and go through the standard CPAN configuration process. Then exit out
-without installing anything. Next, open your .bashrc and add
-
- export PATH=$HOME/local/bin:$HOME/local/script:$PATH
- perlversion=`perl -v | grep 'built for' | awk '{print $4}' | sed -e 's/v//;'`
- export PERL5LIB=$HOME/local/share/perl/$perlversion:$HOME/local/lib/perl/$perlversion:$HOME/local/lib:$PERL5LIB
-
-and log out, then back in again (or run C<". .bashrc"> if you
-prefer). Finally, edit C<.cpan/CPAN/MyConfig.pm> and add
-
- 'make_install_arg' => qq[SITEPREFIX=$ENV{HOME}/local],
- 'makepl_arg' => qq[INSTALLDIRS=site install_base=$ENV{HOME}/local],
-
-Now you can install the modules you need using CPAN as normal; they
-will be installed into your local directory, and perl will pick them
-up. Finally, change directory into the root of your virtual host and
-symlink your application's script directory in:
-
- cd path/to/mydomain.com
- ln -s ~/lib/MyApp/script script
-
-And add the following lines to your .htaccess file (assuming the server
-is setup to handle .pl as fcgi - you may need to rename the script to
-myapp_fastcgi.fcgi and/or use a SetHandler directive):
-
- RewriteEngine On
- RewriteCond %{REQUEST_URI} !^/?script/myapp_fastcgi.pl
- RewriteRule ^(.*)$ script/myapp_fastcgi.pl/$1 [PT,L]
-
-Now C<http://mydomain.com/> should now Just Work. Congratulations, now
-you can tell your friends about your new website (or in our case, tell
-the client it's time to pay the invoice :) )
-
-=head2 FastCGI Deployment
-
-FastCGI is a high-performance extension to CGI. It is suitable
-for production environments.
-
-=head3 Pros
-
-=head4 Speed
-
-FastCGI performs equally as well as mod_perl. Don't let the 'CGI' fool you;
-your app runs as multiple persistent processes ready to receive connections
-from the web server.
-
-=head4 App Server
-
-When using external FastCGI servers, your application runs as a standalone
-application server. It may be restarted independently from the web server.
-This allows for a more robust environment and faster reload times when
-pushing new app changes. The frontend server can even be configured to
-display a friendly "down for maintenance" page while the application is
-restarting.
-
-=head4 Load-balancing
-
-You can launch your application on multiple backend servers and allow the
-frontend web server to load-balance between all of them. And of course, if
-one goes down, your app continues to run fine.
-
-=head4 Multiple versions of the same app
-
-Each FastCGI application is a separate process, so you can run different
-versions of the same app on a single server.
-
-=head4 Can run with threaded Apache
-
-Since your app is not running inside of Apache, the faster mpm_worker module
-can be used without worrying about the thread safety of your application.
-
-=head3 Cons
-
-You may have to disable mod_deflate. If you experience page hangs with
-mod_fastcgi then remove deflate.load and deflate.conf from mods-enabled/
-
-=head4 More complex environment
-
-With FastCGI, there are more things to monitor and more processes running
-than when using mod_perl.
-
-=head3 Setup
-
-=head4 1. Install Apache with mod_fastcgi
-
-mod_fastcgi for Apache is a third party module, and can be found at
-L<http://www.fastcgi.com/>. It is also packaged in many distributions,
-for example, libapache2-mod-fastcgi in Debian.
-
-=head4 2. Configure your application
-
- # Serve static content directly
- DocumentRoot /var/www/MyApp/root
- Alias /static /var/www/MyApp/root/static
-
- FastCgiServer /var/www/MyApp/script/myapp_fastcgi.pl -processes 3
- Alias /myapp/ /var/www/MyApp/script/myapp_fastcgi.pl/
-
- # Or, run at the root
- Alias / /var/www/MyApp/script/myapp_fastcgi.pl/
-
-The above commands will launch 3 app processes and make the app available at
-/myapp/
-
-=head3 Standalone server mode
-
-While not as easy as the previous method, running your app as an external
-server gives you much more flexibility.
-
-First, launch your app as a standalone server listening on a socket.
-
- script/myapp_fastcgi.pl -l /tmp/myapp.socket -n 5 -p /tmp/myapp.pid -d
-
-You can also listen on a TCP port if your web server is not on the same
-machine.
-
- script/myapp_fastcgi.pl -l :8080 -n 5 -p /tmp/myapp.pid -d
-
-You will probably want to write an init script to handle starting/stopping
-of the app using the pid file.
-
-Now, we simply configure Apache to connect to the running server.
-
- # 502 is a Bad Gateway error, and will occur if the backend server is down
- # This allows us to display a friendly static page that says "down for
- # maintenance"
- Alias /_errors /var/www/MyApp/root/error-pages
- ErrorDocument 502 /_errors/502.html
-
- FastCgiExternalServer /tmp/myapp.fcgi -socket /tmp/myapp.socket
- Alias /myapp/ /tmp/myapp.fcgi/
-
- # Or, run at the root
- Alias / /tmp/myapp.fcgi/
-
-=head3 More Info
-
-L<Catalyst::Engine::FastCGI>.
-
-=head2 Development server deployment
-
-The development server is a mini web server written in perl. If you
-expect a low number of hits or you don't need mod_perl/FastCGI speed,
-you could use the development server as the application server with a
-lightweight proxy web server at the front. However, consider using
-L<Catalyst::Engine::HTTP::Prefork> for this kind of deployment instead, since
-it can better handle multiple concurrent requests without forking, or can
-prefork a set number of servers for improved performance.
-
-=head3 Pros
-
-As this is an application server setup, the pros are the same as
-FastCGI (with the exception of speed).
-It is also:
-
-=head4 Simple
-
-The development server is what you create your code on, so if it works
-here, it should work in production!
-
-=head3 Cons
-
-=head4 Speed
-
-Not as fast as mod_perl or FastCGI. Needs to fork for each request
-that comes in - make sure static files are served by the web server to
-save forking.
-
-=head3 Setup
-
-=head4 Start up the development server
-
- script/myapp_server.pl -p 8080 -k -f -pidfile=/tmp/myapp.pid
-
-You will probably want to write an init script to handle stop/starting
-the app using the pid file.
-
-=head4 Configuring Apache
-
-Make sure mod_proxy is enabled and add:
-
- # Serve static content directly
- DocumentRoot /var/www/MyApp/root
- Alias /static /var/www/MyApp/root/static
-
- ProxyRequests Off
- <Proxy *>
- Order deny,allow
- Allow from all
- </Proxy>
-
- # Need to specifically stop these paths from being passed to proxy
- ProxyPass /static !
- ProxyPass /favicon.ico !
-
- ProxyPass / http://localhost:8080/
- ProxyPassReverse / http://localhost:8080/
-
- # This is optional if you'd like to show a custom error page
- # if the proxy is not available
- ErrorDocument 502 /static/error_pages/http502.html
-
-You can wrap the above within a VirtualHost container if you want
-different apps served on the same host.
-
-=head2 Quick deployment: Building PAR Packages
-
-You have an application running on your development box, but then you
-have to quickly move it to another one for
-demonstration/deployment/testing...
-
-PAR packages can save you from a lot of trouble here. They are usual Zip
-files that contain a blib tree; you can even include all prereqs and a
-perl interpreter by setting a few flags!
-
-=head3 Follow these few points to try it out!
-
-1. Install Catalyst and PAR 0.89 (or later)
-
- % perl -MCPAN -e 'install Catalyst'
- ...
- % perl -MCPAN -e 'install PAR'
- ...
-
-2. Create a application
-
- % catalyst.pl MyApp
- ...
- % cd MyApp
-
-Recent versions of Catalyst (5.62 and up) include
-L<Module::Install::Catalyst>, which simplifies the process greatly. From the shell in your application directory:
-
- % perl Makefile.PL
- % make catalyst_par
-
-You can customise the PAR creation process by special "catalyst_par_*" commands
-available from L<Module::Install::Catalyst>. You can add these commands in your
-Makefile.PL just before the line containing "catalyst;"
-
- #Makefile.PL example with extra PAR options
- use inc::Module::Install;
-
- name 'MyApp';
- all_from 'lib\MyApp.pm';
-
- requires 'Catalyst::Runtime' => '5.80005';
- <snip>
- ...
- <snip>
-
- catalyst_par_core(1); # bundle perl core modules in the resulting PAR
- catalyst_par_multiarch(1); # build a multi-architecture PAR file
- catalyst_par_classes(qw/
- Some::Additional::Module
- Some::Other::Module
- /); # specify additional modules you want to be included into PAR
- catalyst;
-
- install_script glob('script/*.pl');
- auto_install;
- WriteAll;
-
-Congratulations! Your package "myapp.par" is ready, the following
-steps are just optional.
-
-3. Test your PAR package with "parl" (no typo)
-
- % parl myapp.par
- Usage:
- [parl] myapp[.par] [script] [arguments]
-
- Examples:
- parl myapp.par myapp_server.pl -r
- myapp myapp_cgi.pl
-
- Available scripts:
- myapp_cgi.pl
- myapp_create.pl
- myapp_fastcgi.pl
- myapp_server.pl
- myapp_test.pl
-
- % parl myapp.par myapp_server.pl
- You can connect to your server at http://localhost:3000
-
-Yes, this nifty little starter application gets automatically included.
-You can also use "catalyst_par_script('myapp_server.pl')" to set a
-default script to execute.
-
-6. Want to create a binary that includes the Perl interpreter?
-
- % pp -o myapp myapp.par
- % ./myapp myapp_server.pl
- You can connect to your server at http://localhost:3000
=head2 Serving static content
Static::Simple is a plugin that will help to serve static content for your
application. By default, it will serve most types of files, excluding some
standard Template Toolkit extensions, out of your B<root> file directory. All
-files are served by path, so if B<images/me.jpg> is requested, then
-B<root/images/me.jpg> is found and served.
+files are served by path, so if F<images/me.jpg> is requested, then
+F<root/images/me.jpg> is found and served.
=head3 Usage
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.
=head3 Configuring
Static content is best served from a single directory within your root
-directory. Having many different directories such as C<root/css> and
-C<root/images> requires more code to manage, because you must separately
-identify each static directory--if you decide to add a C<root/js>
+directory. Having many different directories such as F<root/css> and
+F<root/images> requires more code to manage, because you must separately
+identify each static directory--if you decide to add a F<root/js>

contrast, keeping all static directories as subdirectories of a main

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->config->{root},
- '/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->{static}->{ignore_extensions} = [
- qw/tmpl tt tt2 html xhtml/
- ];
+ 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}->{ignore_dirs} = [ qw/tmpl css/ ];
+ MyApp->config( static => {
+ ignore_dirs => [ qw/tmpl css/ ],
+ });
