Getting class name without module

[Jari Williamsson]

Is there a method available to get only the class name, without getting
the module name prior to it? Alternatively, to get the class name within
the current name space context?

For example, self.class could return something like this:
MyModule::MyClass
(I would like to only get the "MyClass" part.)

Or do I have to resort to string manipulation/regexps?


Best regards,

Jari Williamsson

Indeed, you do it by hand, something like this:

name.split('::').last || ''

-- fxn

If you are using ActiveSupport:

MyModule::MyClass.to_s.demodulize # => "MyClass"
