NAME Jifty - an application framework SYNOPSIS # Object containing lots of web related goodies... my $web = Jifty->web; my $request = Jifty->web->request; my $response = Jifty->web->response; my $link = Jifty->web->link( label => _('W00t'), url => '/whatsit' ); # Retrieve information from your application's etc/config.yml file. my $config = Jifty->config; # Retrieve the Jifty::DBI handle my $handle = Jifty->handle; # Load an application class, very handy in plugins my $class = Jifty->app_class('Model', 'Foo'); my $foo = $class->new; $foo->create( frobnicate => 42 ); # Configure information related to your application's actions my $api = Jifty->api; # Make parts of your page "subscribe" to information in a fragment my $subs = Jifty->subs; # Share information via IPC::PubSub in your application my $bus = Jifty->bus; # Retrieve general information about Mason my $handler = Jifty->handler; DESCRIPTION Yet another web framework. What's cool about Jifty? (Buzzwords) DRY (Don't Repeat Yourself) Jifty tries not to make you say things more than once. Full-stack Out of the proverbial box, Jifty comes with one way to do everything you should need to do: One database mapper, one templating system, one web services layer, one AJAX toolkit, one set of handlers for standalone or FastCGI servers. We work hard to make all the bits play well together, so you don't have to. Continuations With Jifty, it's easy to let the user go off and do something else, like fill out a wizard, look something up in the help system or go twiddle their preferences and come right back to where they were. Form-based dispatch This is one of the things that Jifty does that we've not seen anywhere else. Jifty owns your form rendering and processing. This means you never need to write form handling logic. All you say is "I want an input for this argument here" and Jifty takes care of the rest. (Even autocomplete and validation) A Pony Jifty is the only web application framework that comes with a pony. Introduction If this is your first time using Jifty, Jifty::Manual::Tutorial is probably a better place to start. METHODS new PARAMHASH This class method instantiates a new "Jifty" object. This object deals with configuration files, logging and database handles for the system. Before this method returns, it calls the application's "start" method (i.e. "MyApp->start") to handle any application-specific startup. Most of the time, the server will call this for you to set up your "Jifty" object. If you are writing command-line programs that want to use your libraries (as opposed to web services) you will need to call this yourself. See Jifty::Config for details on how to configure your Jifty application. Arguments no_handle If this is set to true, Jifty will not create a Jifty::Handle and connect to a database. Only use this if you're about to drop the database or do something extreme like that; most of Jifty expects the handle to exist. Defaults to false. logger_component The name that Jifty::Logger will log under. If you don't specify anything Jifty::Logger will log under the empty string. See Jifty::Logger for more information. config An accessor for the Jifty::Config object that stores the configuration for the Jifty application. logger An accessor for our Jifty::Logger object for the application. You probably aren't interested in this. See "log" for information on how to make log messages. handler An accessor for our Jifty::Handler object. This is another method that you usually don't want to mess with too much. Most of the interesting web bits are handled by "web". handle An accessor for the Jifty::Handle object that stores the database handle for the application. api An accessor for the Jifty::API object that publishes and controls information about the application's Jifty::Actions. app_class(@names) Return Class in application space. For example "app_class('Model', 'Foo')" returns YourApp::Model::Foo. By the time you get it back, the class will have already been required Is you pass a hashref as the first argument, it will be treated as configuration parameters. The only existing parameter is "require", which defaults to true. web An accessor for the Jifty::Web object that the web interface uses. subs An accessor for the Jifty::Subs object that the subscription uses. bus Returns an IPC::PubSub object for the current application. plugins Returns a list of Jifty::Plugin objects for this Jifty application. find_plugin Find plugins by name. class_loader An accessor for the Jifty::ClassLoader object that stores the loaded classes for the application. setup_database_connection Set up our database connection. Optionally takes a paramhash with a single argument. This method is automatically called by "new". no_handle Defaults to false. If true, Jifty won't try to set up a database handle pre_init Defaults to false. If true, plugins are notified that this is a pre-init, any trigger registration in "init()" should not happen during this stage. Note that model mixins' "register_triggers" is unrelated to this. If "no_handle" is set or our application's config file is missing a "Database" configuration section or *has* a "SkipDatabase: 1" directive in its framework configuration, does nothing. app_instance_id Returns a globally unique id for this instance of this jifty application. This value is generated the first time it's accessed background SUB Forks a background process, and ensures that database connections and sockets are not shared with the parent process. admin_mode Returns true if the application is in admin mode. This should be used instead of "Jifty->config->framework('AdminMode')".
