Class Method Details

.inherited(subclass) ⇒ Object

Registers any subclasses with status codes for easy lookup by set_status in Merb::Controller.

Inheritance ensures this method gets inherited by any subclasses, so it goes all the way down the chain of inheritance.

Parameters

subclass<Merb::ControllerExceptions::Base>

The Exception class that is inheriting from Merb::ControllerExceptions::Base

def inherited(subclass)
  # don't set the constant yet - any class methods will be called after self.inherited
  # unless self.status = ... is set explicitly, the status code will be inherited
  register_status_code(subclass, self.status) if self.status?
end

.status ⇒ Object Also known as: to_i

Get the actual status-code for an Exception class.

As usual, this can come from a constant upwards in the inheritance chain.

Returns

Fixnum

The status code of this exception.
