Jifty::Action::Record -- An action tied to a record in the database.
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.
Access to the underlying Jifty::Record object for this action is through the record accessor.
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.
If the action returns true for report_detailed_message,
report the message returned by the model classes as the resulting message.
For Update actions,
Put the per-field message in detailed_messages field of action result content.
The default is false.
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.
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.
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.
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.
Throws an error unless it is overridden; use Jifty::Action::Record::Create, ::Update, or ::Delete
