Rails how do I check for existance of a class when not instantiated yet?

Question

I have a utility class defined with a bunch of class methods. In the Rails console, when I search for the class using Object.const_defined? it returns false. But after calling one of the class methods or creating an instance of the class, Object.const_defined? returns true. Is this because of some kind of lazy loading instantiation kind of thing? Is there another way I can check for the existence of a class which will return true, even if I haven't instantiated anything yet?

Answer 1

This is kind of a hack, but it works

Object.const_get(:ClassName).is_a?(Class) rescue false

Above statement will return true if the class is defined and return false otherwise
