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. You may need to override the "record_class" method, if Jifty cannot determine the record class of this action.
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.report_detailed_messages
If the action returns true for "report_detailed_message", put the per-field messages as "detailed_messages" in the result content for Update actions. The default is true.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 primary 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_columns
Returns the list of columns objects on the object that the action can update. This defaults to all of the "containers" or the non-"private", non-"virtual" and non-"serial" columns of the object.possible_fields
Returns the list of the "possible_columns"' names.Usually at the end names are required, however for subclassing column objects are better, or this method in a subclass turns out to be "map to column" - "filter" - "map to name" chain.
take_action
Throws an error unless it is overridden; use Jifty::Action::Record::Create, ::Update, or ::DeleteSEE ALSO
