NAME

       Jifty::Logger -- A master class for Jifty's logging framework

DESCRIPTION

       Jifty uses the Log4perl module to log error messages. In Jifty programs there's two ways you can get something logged:

       Firstly, Jifty::Logger captures all standard warnings that Perl emits.  So in addition to everything output from perl via the warnings
       pragmas, you can also log messages like so:

	   warn("The WHAM is overheating!");

       This doesn't give you much control however.  The second way allows you to specify the level that you want logging to occur at:

	   Jifty->log->debug("Checking the WHAM");
	   Jifty->log->info("Potential WHAM problem detected");
	   Jifty->log->warn("The WHAM is overheating");
	   Jifty->log->error("PANIC!");
	   Jifty->log->fatal("Someone call Eddie Murphy!");

   Configuring Log4perl
       Unless you specify otherwise in the configuration file, Jifty will supply a default Log4perl configuration.

       The default log configuration that logs all messages to the screen (i.e. to STDERR, be that directly to the terminal or to the FastCGI log
       file.)  It will log all messages of equal or higher priority to the LogLevel configuration option.

	   ---
	   framework:
	     LogLevel: DEBUG

       You can override the LogLevel configuration option by setting JIFTY_LOG_LEVEL in your environment.

       You can tell Jifty to use an entirely different Logging configuration by specifying the filename of a standard Log4perl config file in the
       LogConfig config option (see Log::Log4perl for the format of this config file.)

	   ---
	   framework:
	     LogConfig: etc/log4perl.conf

       Note that specifying your own config file prevents the LogLevel config option from having any effect.

       You can tell Log4perl to check that file periodically for changes.  This costs you a little in application performance, but allows you to
       change the logging level of a running application.  You need to set LogReload to the frequency, in seconds, that the file should be
       checked.

	   ---
	   framework:
	     LogConfig: etc/log4perl.conf
	     LogReload: 10

       (This is implemented with Log4perl's init_and_watch functionality)

METHODS

   new COMPONENT
       This class method instantiates a new "Jifty::Logger" object. This object deals with logging for the system.

       Takes an optional name for this Jifty's logging "component" - See Log::Log4perl for some detail about what that is.  It sets up a "warn"
       handler which logs warnings to the specified component.

   _warning_action
       change the Log4Perl action from warn to error|info|etc based on the content of the warning.

       Added because DBD::Pg throws up NOTICE and other messages as warns, and we really want those to be info (or error, depending on the code).
       List based on Postgres documentation

       TODO: needs to be smarter than just string matching

       returns a valid Log::Log4Perl action, if nothing matches will return the default of warn since we're in a __WARN__ handler

NAME

       Jifty::Action::Record::Create - Automagic creation action

DESCRIPTION

       This class is used as the base class for Jifty::Actions that are merely creating 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 creates.

METHODS

   arguments
       Set the default value in each of the fields to whatever the default of the column is in the model

   take_action
       Overrides the virtual "take_action" method on Jifty::Action to call the appropriate "Jifty::Record"'s "create" method when the action is
       run, thus creating a new object in the database.

       The "id" of the new row is returned in the "id" content of the Jifty::Result for the action.  You can use this in conjunction with request
       mapping in order to give later parts of the request access to the "id".

   create_record
       This method actually performs the call to "record->create". It receives as arguments the parameter hash and should return the message for
       the user, indicating success or failure.

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

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

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

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

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