Jifty::Web - Web framework for a Jifty application
Creates a new Jifty::Web object
Returns a HTML::Mason::Request object
Send a string to the browser.
Returns the root url of this Jifty application. This is pulled from the configuration file. Takes an optional named path which will form the path part of the resulting URL.
Returns a unique identifier, guaranteed to be unique within the runtime of a particular process (i.e., within the lifetime of Jifty.pm). There's no sort of global uniqueness guarantee, but it should be good enough for generating things like moniker names.
Sets up the current session object (a Jifty::Web::Session tied
hash). Aborts if the session is already loaded.
Returns the current session's hash. In a regular user environment, it persists, but a request can stop that by handing it a regular hash to use.
Getter/setter for the current user; this gets or sets the 'user' key in the session. These are Jifty::Record objects.
If a temporary_current_user has been set, will return that instead.
If the current application has no loaded current user, we get an empty
app-specific CurrentUser object. (This
ApplicationClass::CurrentUser class, a subclass of
Jifty::CurrentUser, is autogenerated if it doesn't exist).
Sets the current request's current_user to USER if set.
This value will _not_ be persisted to the session at the end of the request. To restore the original value, set temporary_current_user to undef.
This method sets up a current session, and then processes the given Jifty::Request object. If no request object is given, processes the request object in request.
Each action on the request is vetted in three ways -- first, it must
be marked as active by the Jifty::Request (this is the default).
Second, it must be in the set of allowed classes of actions (see
is_allowed in Jifty::API). Finally, the action must validate. If it
passes all of these criteria, the action is fit to be run.
Before they are run, however, the request has a chance to be interrupted and saved away into a continuation, to be resumed at some later point. This is handled by save_continuation in Jifty::Request.
If the continuation isn't being saved, then handle_request goes on
to run all of the actions. If all of the actions are successful, it
looks to see if the request wished to call any continuations, possibly
jumping back and re-running a request that was interrupted in the
past. This is handled by call_continuation in Jifty::Request.
For more details about continuations, see Jifty::Continuation.
Gets or sets the current Jifty::Request object.
Gets or sets the current Jifty::Response object.
Returns the current Jifty::Web::Form object, creating one if there isn't one already.
Creates a new action (an instance of a subclass of
Jifty::Action). The named arguments passed to this method are
passed on to the new method of the action named in CLASS.
If you pass an odd number of arguments, then the first argument
is interpreted as class.
CLASS is qualified, and an instance of that
class is created, passing the Jifty::Web object, the MONIKER,
and any other arguments that new_action was supplied.
MONIKER is a unique designator of an action on a page. The moniker
is content-free and non-fattening, and may be auto-generated. It is
used to tie together arguments that relate to the same action.
ORDER defines the order in which the action is run, with lower
numerical values running first.
ARGUMENTS are passed to the new in Jifty::Action method. In
addition, if the current request ($self->request) contains an
action with a matching moniker, any arguments that are in that
requested action but not in the PARAMHASH list are set. This
implements "sticky fields".
As a contrast to add_action in Jifty::Web::Form, this does not add the action to the current form -- instead, the first form field to be rendered will automatically register the action in the current form field at that time.
Given a Jifty::Request::Action, creates a new action using new_action.
Returns an array of Jifty::Action objects, one for each Jifty::Request::Action that is marked as failed in the current response.
As failed_actions, but for actions that completed successfully; less often used.
Gets or sets the next page for the framework to show. This is
normally set during the take_action method or a Jifty::Action
Gets or sets whether we should force a redirect to next_page, even
if it's already the current page. You might set this, e.g. to force a
redirect after a POSTed action.
Returns true if we need to redirect, now that we've processed all the
actions. We need a redirect if either next_page is different from
the current page, or force_redirect has been set.
Handle redirection inside webservices call. This is meant to be hooked by plugin that knows what to do with it.
Redirect to the next page. If you pass this method a parameter, it redirects to that URL rather than next_page.
It creates a continuation of where you want to be, and then calls it. If you want to redirect to a page with parameters, pass in a Jifty::Web::Form::Clickable object.
Returns the Jifty::Request of our enclosing continuation, or an empty Jifty::Request if we are not in a continuation.
If called in non-void context, creates and renders a Jifty::Web::Form::Clickable with the given PARAMHASH, forcing a continuation save.
In void context, does a redirect to the URL that the Jifty::Web::Form::Clickable object generates.
Both of these versions preserve all state variables by default.
Does an instant redirect to the url generated by the Jifty::Web::Form::Clickable object generated by the PARAMHASH.
Generates and renders a Jifty::Web::Form::Clickable using the given PARAMHASH.
If called in non-void context, creates and renders a Jifty::Web::Form::Clickable using the given PARAMHASH, additionally defaults to calling the current continuation.
Takes an additional argument, to, which can specify a default path
to return to if there is no current continuation.
In void context, does a redirect to the URL that the Jifty::Web::Form::Clickable object generates.
Returns true if PATH is a valid template inside your template root. This checks for both Template::Declare and HTML::Mason Templates. Specifically, returns a reference to the handler which can process the template.
If PATH is a reference to the path, it will update the path to
append /index.html if the path in question doesn't exist, but the
index does.
Use our templating system to render a template. Searches through view_handlers in Jifty::Handler to find the first handler which provides the given template, and caches the handler for future requests.
Catches errors, and redirects to /errors/500; also shows
/errors/404 if the template cannot be found.
Outputs any messages that have been added, in <div id="messages"> and <div id="errors"> tags. Messages are added by calling message in Jifty::Result.
If a moniker is specified, only messages for that moniker are rendered.
Render success messages for the given moniker, or all of them if no moniker is given.
Render error messages for the given moniker, or all of them if no moniker is given.
Output any messages of the given TYPE (either 'error' or 'message') in a <div id="TYPEs"> tag. If a moniker is given, only renders messages for that action. Internal helper for render_success_messages and render_errors.
Returns an URL-encoded query string piece representing the arguments passed to it.
HTML-escapes the given string and returns it
URI-escapes the given string and returns it
Returns a <link> tag for the compressed CSS
Pushes files onto Jifty->web->css_files
Returns a <script> tag for the compressed Javascript.
Your application specific javascript goes in share/web/static/js/app.js. This will be automagically included if it exists.
If you want to add javascript behaviour to your page using CSS
selectors then put your behaviour rules in
share/web/static/js/app_behaviour.js which will also be
automagically included if it exists. The behaviour.js library is
included by Jifty. For more information on behaviour.js see
http://bennolan.com/behaviour/.
However if you want to include other javascript libraries you need to
add them to the javascript_libs array of your application. Do this in
the start sub of your main application class. For example if your
application is Foo then in Foo.pm in lib
sub start {
Jifty->web->add_javascript(qw( jslib1.js jslib2.js ) );
}
The add_javascript method will append the files to javascript_libs. If you need a different order, you'll have to massage javascript_libs directly.
Jifty will look for javascript libraries under share/web/static/js/ by default as well as any plugin static roots.
Pushes files onto Jifty->web->javascript_libs
Removes the given files from Jifty->web->javascript_libs.
This is intended for plugins or applications that provide another version of the functionality given in our default JS libraries. For example, the CSSQuery plugin will get rid of the cssQuery-jQuery.js back-compat script.
Pushes URLs onto Jifty->web->external_javascript_libs
Gets a page specific variable from the request object.
Takes a key-value pair for variables to serialize and hand off to the next page.
Behind the scenes, these variables get serialized into every link or form that is marked as 'state preserving'. See Jifty::Web::Form::Clickable.
Passing undef as a value will remove the variable
Returns all of the state variables that have been set for the next request, as a hash;
N.B. These are not prefixed with J:V-, as they were in earlier
versions of Jifty
Remove all the state variables to be serialized for the next request.
Given a fully QUALIFIED NAME of a region, returns the
Jifty::Web::PageRegion with that name, or undef if no such region
exists.
The provided PARAMHASH is used to create and render a
Jifty::Web::PageRegion; the PARAMHASH is passed directly to its
new in Jifty::Web::PageRegion method, and then
render in Jifty::Web::PageRegion is called.
Replaces the current region with a new region and renders it Returns undef if there's no current region
Returns the current Jifty::Web::PageRegion, or undef if there is none.
Returns the fully qualified name of the current
Jifty::Web::PageRegion, or the empty string if there is none. If
REGION is supplied, gives the qualified name of REGION were it
placed in the current region. You may also use a literal region name.
Returns the fully qualified name of the current
Jifty::Web::PageRegion's parent, or the empty string if there is none. If
REGION is supplied, gives the qualified name of REGION were it
placed in the parent region. You may also use a literal region name.
Indicates whether the current request was made using SSL.
