Jifty::View::Declare::Helpers.3pm

NAME

Jifty::View::Declare::Helpers - Additional subroutines for Jifty TD templates

DESCRIPTION

This library provides mixins to help build your application's user interface.

METHODS

form CODE

Takes a subroutine reference or block of perl as its only argument and renders it as a Jifty "form".

hyperlink

Shortcut for ``link'' in Jifty::Web.

tangent

Shortcut for ``tangent'' in Jifty::Web.

redirect

Shortcut for ``redirect'' in Jifty::Web.

new_action

Shortcut for ``new_action'' in Jifty::Web.

render_region

A shortcut for Jifty::Web::PageRegion->new(@_)->render which does the Template::Declare magic necessary to not mix its output with your current page's.

render_action $action_object, $fields, $args_to_pass_to_action

render_action $action_object, $fields, $args_to_pass_to_action

Renders an action out of whole cloth.

Arguments

$action_object

A Jifty::Action object which has already been initialized

$fields

A reference to an array of fields that should be rendered when displaying this action. If left undefined, all of the action's fields will be rendered.

$args_to_pass_to_action

A hashref of arguments that should be passed to $action->form_field for every field of this action.

form_return

Shortcut for ``return'' in Jifty::Web::Form.

form_submit

Shortcut for ``submit'' in Jifty::Web::Form.

form_next_page

Shortcut for ``next_page'' in Jifty::Web::Form.

request

Shortcut for ``request'' in Jifty::Web.

current_user

Shortcut for ``current_user'' in Jifty::Web.

get args

Returns arguments as set in the dispatcher or with ``set'' below. If called in scalar context, pulls the first item in "args" and returns it. If called in list context, returns the values of all items in "args".

set key => val [ key => val ...]

Sets arguments for later grabbing with get.

render_param $action @args

render_param $action @args

Takes an action and one or more arguments to pass to Jifty::Action-form_field>.

page

  template 'foo' => page {{ title is 'Foo' } ... };
 
   or
 
  template 'foo' => page { title => 'Foo' } content { ... };
 
 

Renders an HTML page wrapped in ``wrapper'', after calling ``/_elements/nav'' and setting a content type. Generally, you shouldn't be using ``/_elements/nav'' but a Dispatcher rule instead.

If "page/content" calling convention is used, the return value of the first sub will be passed into wrapper as the second argument as a hashref, as well as the last argument for the content sub.

content

Helper function for page { ... } content { ... }

wrapper $coderef

wrapper $coderef

Render a page. $coderef is a Template::Declare coderef. This badly wants to be redone.

js_handlers

Allows you to put javascript handlers, a la Jifty::Web::Form::Element, onto arbitrary HTML elements:

   div {
       js_handlers {
           onclick => { path => "/some/region/path" }
       }
   }
