NAME

       Catalyst::Plugin::Authorization::Roles - Role based authorization for Catalyst based on Catalyst::Plugin::Authentication

SYNOPSIS

	   use Catalyst qw/
	       Authentication
	       Authorization::Roles
	   /;

	   sub delete : Local {
	       my ( $self, $c ) = @_;

	       $c->assert_user_roles( qw/admin/ ); # only admins can delete

	       $c->model("Foo")->delete_it();
	   }

DESCRIPTION

       Role based access control is very simple: every user has a list of roles, which that user is allowed to assume, and every restricted part
       of the app makes an assertion about the necessary roles.

       With "assert_user_roles", if the user is a member in all of the required roles access is granted. Otherwise, access is denied. With
       "assert_any_user_role" it is enough that the user is a member in one role.

       There are alternative approaches to do this on a per action basis, see Catalyst::ActionRole::ACL.

       For example, if you have a CRUD application, for every mutating action you probably want to check that the user is allowed to edit. To do
       this, create an editor role, and add that role to every user who is allowed to edit.

	   sub edit : Local {
	       my ( $self, $c ) = @_;
	       $c->assert_user_roles( qw/editor/ );
	       $c->model("TheModel")->make_changes();
	   }

       When this plugin checks the roles of a user it will first see if the user supports the self check method.

       When this is not supported the list of roles is extracted from the user using the "roles" method.

       When this is supported, the "check_roles" method will be used to delegate the role check to the user class. Classes like the one provided
       with iCatalyst::Authentication::Store::DBIx::Class optimize the check this way.

METHODS

       assert_user_roles [ $user ], @roles
	   Checks that the user (as supplied by the first argument, or, if omitted, "$c->user") has the specified roles.

	   If for any reason ("$c->user" is not defined, the user is missing a role, etc) the check fails, an error is thrown.

	   You can either catch these errors with an eval, or clean them up in your "end" action.

       check_user_roles [ $user ], @roles
	   Takes the same args as "assert_user_roles", and performs the same check, but instead of throwing errors returns a boolean value.

       assert_any_user_role [ $user ], @roles
	   Checks that the user (as supplied by the first argument, or, if omitted, "$c->user") has at least one of the specified roles.

	   Other than that, works like "assert_user_roles".

       check_any_user_role [ $user ], @roles
	   Takes the same args as "assert_any_user_role", and performs the same check, but instead of throwing errors returns a boolean value.

NAME

       Catalyst::Plugin::Cache::Store::FastMmap - DEPRECATED - FastMmap cache store for Catalyst::Plugin::Cache.

SYNOPSIS

	   # instead of using this plugin, you can now do this:

	   use Catalyst qw/
	       Cache
	   /;

	   __PACKAGE__->config( cache => {
	       backend => {
		   class => "Cache:FastMmap",
		   share_file => "/path/to/file",
		   cache_size => "16m",
	       },
	   });

STATUS

       This plugin is deprecated because Cache::FastMmap no longer needs to be wrapped to store plain values. It is still available on the CPAN
       for backwards compatibility and will still work with newer versions of Cache::FastMmap with a slight performance degredation.

DESCRIPTION

       This store plugin is a bit of a wrapper for Cache::FastMmap.

       While you could normally just configure with

	   backend => {
	       class => "Cache::FastMmap",
	       share_file => ...,
	   }

       Cache::FastMmap can't store plain values by default. This module ships with a subclass that will wrap all values in a scalar reference
       before storing.

       This store plugin will try to provide a default "share_file" as well, that won't clash with other apps.

CONFIGURATION

       See "CONFIGURATION" in Catalyst::Plugin::Cache for a general overview of cache plugin configuration.

       This plugin just takes a hash reference in the backend field and passes it on to Cache::FastMmap.

SEE ALSO

       Catalyst::Plugin::Cache, Cache::FastMmap.
