Description

Provides methods for creating navigation links and access control

Subroutines/Methods

access_check

$state = $c->model( q(Navigation) )->access_check( @args );

Expects to be passed the stash ($c->stash), a key to search in the stash ($args[0]) and a level or room to search for ($args[1]). It returns 0 if the ACL on the requested level/room permits access to the current user. It returns 1 if no ACL was found. It returns 2 if the current user is unknown and the level/room's ACL did not contain the value any which would permit anonymous access. It returns 3 if the current user is explicitly denied access to the selected level/room

This method is called from /add_main_menu (via the /allowed method which negates the result) to determine which levels the current user has access to. It is also called by /auto to determine if access to the requested endpoint is permitted

It could also be used from an application controller method to allow the display logic to display content based on the users identity

access_control_form

$c->model( q(Navigation) )->form( $level, $room );

Stuffs the stash with the data for the form that controls access to levels and rooms

add_main_menu

$c->model( q(Navigation) )->add_main_menu;

Adds data to the stash to generate the main navigation menu. The menu uses a Cone Trees layout which has been flattened to produce a visual trail of breadcrumbs effect, i.e. Home > Reception > Tutorial

add_menu_back

$c->model( q(Navigation) )->add_menu_back( $args, $menu, $ord );

Adds a history back link to the main navigation menu

add_menu_blank

$c->model( q(Navigation) )->add_menu_blank( $args, $menu, $ord );

Adds some filler to the main navigation menu

add_menu_close

$c->model( q(Navigation) )->add_menu_close( $args, $menu, $ord );

Adds a window close link to the main navigation menu

$c->model( q(Navigation) )->add_quick_links;

Stashes the data used to display "quick" navigation links. These usually appear in the header and allow single click access to any endpoint. They are identified in the configuration by adding a quick_link attribute to the rooms element. The quick_link attribute value is an integer which determines the display order

add_tools_menu

$c->model( q(Navigation) )->add_tools_menu;

Adds the stash data for the tools menu. This contains a selection of utility options including: toggle runtime debugging, toggle footer, skin switching, context sensitive help, about popup, email feedback and logout option

allowed

$bool = $c->model( q(Navigation) )->allowed( @args );

Negates the result returned by "access_check". Called from "add_main_menu" to determine if a page is accessible to a user. If the user does not have access then do not display a link to it

push_menu_item

$c->model( q(Navigation) )->push_menu_item( $name, $order, $ref );

Pushes an anchor widget $ref onto a menu structure

retrieve

$data = $c->model( q(Navigation) )->retrieve;

Called by "sitemap" this method generates the table data used by HTML::FormWidgets

room_manager_form

$c->model( q(Navigation) )->room_manager( $level, $room );

Allows for editing of the level and room definition elements in the configuration files

sitemap

$c->model( q(Navigation) )->sitemap;

Displays a table of all the pages on the site
