Jifty::Param - Parameters for Jifty actions
Describes a parameter to a
Do not construct this by hand -- use Jifty::Param::Schema in the action package to declare parameters instead.
Although this class is not derived from Jifty::Web::Form::Field, it does share the accessors from it; see Jifty::Web::Form::Field, for the list of possible keys that each parameter can have.
In addition to the list there, you may use these additional keys:
A boolean which,
indicates that the argument must be present in the
arguments passed to create the action,
rather than being expected to be set later.
Defaults to false.
An array reference. Each element should be either:
displayfield for the string to display for the value, and a
valuefield for the value to actually send to the server.
collectionfield containing a Jifty::Collection, and
value_fromfields containing the names of methods to call on each record in the collection to get
Just like valid_values, but represents the list of suggested values, instead of the list of acceptable values.
An integer of how the parameter sorts relative to other parameters. This is usually implicitly generated by its declaration order.
Creates a new Jifty::Param object. Note that unlike Jifty::Web::Form::Field, the object is never magically reblessed into a subclass. Should only be called implicitly from a Jifty::Param::Schema declaration.
