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.
