Today we will take a trip into the wonderful and mystical world of uri_for. The basic premise behind uri_for is to make generating URIs for actions with parameters easy and fun (well as fun as URIs get). $c->uri_for will return the URL for the current actions namespace, so, if you are in Controller MyApp::Children it will return: $c->uri_for() http://localhost:3000/children for any action you are

Catalyst Advent - Day 24 - Authorization NOTE: This article is now obsolete. Please refer to http://dev.catalyst.perl.org/wiki/gettingstarted/howtos/interim_authorization_and_authentication_example. Introduction Authorization is the step that comes after authentication. Authentication establishes that the user agent is really representing the user we think it's representing, and then authorization

Catalyst Advent - Day 23 - Static::Simple Introduction 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 root file directory. All files are served by path, so if images/me.jpg is requested, then root/images/me.jpg is found and served. Usage Using the

Catalyst Advent - Day 22 - Action Types Introduction A Catalyst application is driven by one or more Controller modules. There are a number of ways that Catalyst can decide which of the methods in your controller modules it should call. Controller methods are also called actions, because they determine how your catalyst application should (re-)act to any given URL. When the application is started

Catalyst provides a convenient way of testing your application during development and before deployment in a real environment. Catalyst::Test makes it possible to run the same tests both locally (without an external daemon) and against a remote server via HTTP.

Adding RSS feeds to your stuff in Catalyst is really simple. I'll show two different aproaches here, but the basic premise is that you forward to the normal view action first to get the objects, then handle the output differently This is the aproach we chose in Agave (http://dev.rawmode.org/). sub rss : Local { my ($self,$c) = @_; $c->forward('view'); $c->stash->{template}='rss.tt'; } Then you nee

Catalyst makes it easy to employ several different types of caching to speed up your applications. There are three wrapper plugins around common CPAN cache modules: Cache::FastMmap, Cache::FileCache, and Cache::Memcached. These can be used to cache the result of

DRY is a central principle in Catalyst, yet there is one piece of code that is identical in 90% of all Catalyst applications. sub end : Private { my ($self,$c) = @_; return 1 if $c->res->body; return 1 if $c->response->status =~ /^3\d\d$/; $c->forward( 'MyApp::View::TT' ); } Basically, we want to render a template unless we already have a response, or are redirecting. So, rather than doing this ag

NOTE: This article was written in 2005.

PAR packages can save you from a lot of trouble here. They are usual
