NAME

       Jifty::Action::Record::Update - Automagic update action

DESCRIPTION

       This class is used as the base class for Jifty::Actions that are merely updating Jifty::Record objects.	To use it, subclass it and
       override the "record_class" method to return the name of the Jifty::Record subclass that this action should update.

METHODS

   arguments
       Overrides the "arguments" in Jifty::Action::Record method to further specify that all of the primary keys must have values when submitted;
       that is, they are constructors.

   validate_arguments
       We only need to validate arguments that got submitted -- thus, a mandatory argument that isn't submitted isn't invalid, as it's not going
       to change the record.  This is opposed to the behavior inherited from Jifty::Action, where mandatory arguments must be present for the
       action to run.

       However, constructor arguments are still required.

   take_action
       Overrides the virtual "take_action" method on Jifty::Action to call the appropriate "Jifty::Record"'s "set_" methods when the action is
       run, thus updating the object in the database.

   report_success
       Sets the "message" in Jifty::Result to default success message, "Updated". Override this if you want to report some other more user-
       friendly result.

   possible_columns
       Update actions do not provide fields for columns marked as "private" or "protected".

   _extra_validator_args
       Passes "for => 'update'" to validators.

   _extra_canonicalizer_args
       Passes "for => 'update'" to canonicalizers.

   _extra_autocompleter_args
       Passes "for => 'update'" to autocompleters.

NAME

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

SYNOPSIS

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

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 get
       or load methods without retrieving them from the database.

METHODS

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

   load_by_cols
       Overrides the implementation from Jifty::DBI::Record to add support for 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 }
	 }

   memcached_config
       Returns a hash containing arguments to pass to Cache::Memcached during construction. The defaults are like:

	 (
	     services => [ '127.0.0.1:11211' ],
	     debug    => 0,
	 )

       You may want to override this method if you want a customized cache configuration:

	 sub memcached_config {
	     (
		 servers => [ '10.0.0.15:11211', '10.0.0.15:11212',
			      '10.0.0.17:11211', [ '10.0.0.17:11211', 3 ] ],
		 debug	 => 0,
		 compress_threshold => 10_000,
	     );
	 }

   cache_key_prefix
       Returns the prefix we should prepend to all cache keys. If you're using one memcached for multiple applications, you want this to be
       different for each application or they might end up mingling data.
