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.
subclass<Merb::ControllerExceptions::Base> |
The Exception class that is inheriting from Merb::ControllerExceptions::Base |
:api: public
# File lib/merb-core/controller/exceptions.rb, line 220 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
Get the actual status-code for an Exception class.
As usual, this can come from a constant upwards in the inheritance chain.
Fixnum |
The status code of this exception. |
:api: public
# File lib/merb-core/controller/exceptions.rb, line 174 def status const_get(:STATUS) rescue 0 end
Set the actual status-code for an Exception class.
If possible, set the STATUS constant, and update any previously registered (inherited) status-code.
num<~to_i> |
The status code |
(Integer, nil) |
The status set on this exception, or nil if a status was already set. |
:api: private
# File lib/merb-core/controller/exceptions.rb, line 191 def status=(num) unless self.status? register_status_code(self, num) self.const_set(:STATUS, num.to_i) end end
