jifty::action::record::update
Jifty::Action::Record::Update(3pm) User Contributed Perl Documentation Jifty::Action::Record::Update(3pm)
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.
