Jifty::RightsFrom(3pm)					User Contributed Perl Documentation				    Jifty::RightsFrom(3pm)

NAME

       Jifty::RightsFrom - Delegate access control to a related object

SYNOPSIS

	 package Application::Model::Thing;
	 use Jifty::DBI::Schema;
	 use Application::Record schema {
	   column owner => refers_to Application::Model::Person;
	 }

	 use Jifty::RightsFrom column => 'owner';

DESCRIPTION

       Provides a "delegate_current_user_can" method that various task-related objects can use as a base to make their own access control
       decisions based on their task. "current_user_can" in Jifty::Record uses this method to make an access control decision if it exists.

       Note that this means that a model class can use Jifty::RightsFrom, and still have a custom "current_user_can" method, and they will not
       interfere with each other.

   export_curried_sub HASHREF
       Takes:

       sub_name
	   The subroutine in this package that you want to export.

       export_to
	   The name of the package you want to export to.

       as  The name your new curried sub should be exported into in the package "export_to"

       args (arrayref)
	   The arguments you want to hand to your sub.

   delegate_current_user_can 'column', $column_name, $right_name, @attributes
       Make a decision about permissions based on checking permissions on the column of this record specified in the call to "import". "create",
       "delete", and "update" rights all check for the "update" right on the delegated object. On create, we look in the passed attributes for an
       argument with the name of that column.

NAME

       Jifty::DBI::Record::Cachable - records with caching behavior

SYNOPSIS

	 package Myrecord;
	 use base qw/Jifty::DBI::Record::Cachable/;

DESCRIPTION

       This module subclasses the main Jifty::DBI::Record package to add a caching layer.

       The public interface remains the same, except that records which have been loaded in the last few seconds may be reused by subsequent fetch
       or load methods without retrieving them from the database.

METHODS

   flush_cache
       This class method flushes the _global_ Jifty::DBI::Record::Cachable cache.  All caches are immediately expired.

   _flush_key_cache
       Blow away this record type's key cache

   load_from_hash
       Overrides the implementation from Jifty::DBI::Record to add caching.

   load_by_cols
       Overrides the implementation from Jifty::DBI::Record to add caching.

   _cache_config
       You can override this method to change the duration of the caching from the default of 5 seconds.

       For example, to cache records for up to 30 seconds, add the following method to your class:

	 sub _cache_config {
	     { 'cache_for_sec' => 30 }
	 }
