this creates an infinite recursion - self.default doesn't call the
class method, it's equivalent to writing
def default
default
end
which obviously doesn't work.
You could write
def default
MyClass.default
end
or, equivalently
def default
self.class.default
end
the code as is won't quite work, since ruby will complain if you try
to access an unset class variable, so you need some thing like
class MyClass
@@default = 'this
...
end
@@ variables are visible by instances as well as classes though, so
you could also do
def default
@@default
end
Lastly, active support already includes the cattr_accessor helper that
will create accessors for you
