NAME

Dancer::Plugin::PageHistory - store recent page history for user into session

VERSION

Version 0.005

SYNOPSIS

get '/product/:sku/:name' => sub {
    add_to_history(
        type       => 'product',
        title      => param('name'),
        attributes => { sku => param('sku') }
    );
};

hook 'before_template_render' => sub {
    my $tokens = shift;
    $tokens->{previous_page} = history->previous_page->uri;
};

DESCRIPTION

The add_to_history keyword which is exported by this plugin allows you to add interesting items to the history lists which are returned using the history keyword.

KEYWORDS

add_to_history

Adds a page via "add" in Dancer::Plugin::PageHistory::PageSet. Both of path and query are optional arguments which will be set automatically from the current request if they are not supplied.

history

Returns the current Dancer::Plugin::PageHistory::PageSet object from the user's session.

SUPPORTED SESSION ENGINES

CHI, Cookie, DBIC, JSON, Memcached, Memcached::Fast, MongoDB, PSGI, Simple, Storable, YAML

CAVEATS

Dancer::Session::Cookie and Dancer::Session::PSGI either don't handle destroy at all or else do it wrong so I suggest you avoid those modules if you want things like logout to work.

CONFIGURATION

No configuration is necessarily required.

If you wish to have arguments passed to "new" in Dancer::Plugin::PageHistory::PageSet these can be added to your configuration along with configuration for the plugin itself, e.g.:

   plugins:
     PageHistory:
       add_all_pages: 1
       ingore_ajax: 1 
       history_name: someothername
       PageSet:
         default_type: all
         fallback_page:
           path: "/"
         max_items: 20
         methods:
           - default
           - product
           - navigation

Configuration options for the plugin itself:

• add_all_pages

  Defaults to 0. Set to 1 to have all pages added to the list "default_type" in Dancer::Plugin::PageHistory::PageSet in the "before" hook.

• ignore_ajax

  If "add_all_pages" is true this controls whether ajax requests are added to the list "default_type" in Dancer::Plugin::PageHistory::PageSet in the "before" hook.

  Defaults to 0. Set to 1 to have ajax requests ignored.

• history_name

  This setting can be used to change the name of the key used to store the history object in the session from the default page_history to something else. This is also the key used for name of the token containing the history object that is passed to templates.

HOOKS

This plugin makes use of the following hooks:

before

Add current page to history. See "add_all_pages" and "ignore_ajax".

before_template_render

Puts history into the token page_history.

TODO

• Add more tests

• Add support for more session engines

• Create Dancer2 plugin

• investigate destroy problems with Dancer::Session::Cookie and Dancer::Session::PSGI
