NAME

Jifty::Action::Record -- An action tied to a record in the database.

DESCRIPTION

Represents a web-based action that is a create, update, or delete of a Jifty::Record object. This automatically populates the arguments method of Jifty::Action so that you don't need to bother. To actually use this class, you probably want to inherit from one of Jifty::Action::Record::Create, Jifty::Action::Record::Update, or Jifty::Action::Record::Delete and override the record_class method.

METHODS

record

Access to the underlying Jifty::Record object for this action is through the record accessor.

record_class

This method can either be overridden to return a string specifying the name of the record class, or the name of the class can be passed to the constructor.

new PARAMHASH

Construct a new Jifty::Action::Record (as mentioned in Jifty::Action, this should only be called by framework->new_action. The record value, if provided in the PARAMHASH, will be used to load the "record"; otherwise, the parimary keys will be loaded from the action's argument values, and the "record" loaded from those primary keys.

arguments

Overrides the "arguments" in Jifty::Action method, to automatically provide a form field for every writable attribute of the underlying "record".

This also creates built-in validation and autocompletion methods (validate_$fieldname and autocomplete_$fieldname) for action fields that are defined "validate" or "autocomplete". These methods can be overridden in any Action which inherits from this class.

Additionally, if our model class defines canonicalize_, validate_, or autocomplete_ FIELD, generate appropriate an appropriate canonicalizer, validator, or autocompleter that will call that method with the value to be validated, canonicalized, or autocompleted.

validate_FIELD should return a (success boolean, message) list.

autocomplete_FIELD should return a the same kind of list as Jifty::Action::_autocomplete_argument

canonicalized_FIELD should return the canonicalized value.

possible_fields

Returns the list of fields on the object that the action can update. This defaults to all of the fields of the object.

take_action

Throws an error unless it is overridden; use Jifty::Action::Record::Create, ::Update, or ::Delete
