Hi , Self.methods is static methods using the class name itself you can call the methods and is not available to the instance of the class.

Since everything is an object in Ruby (literally) you have multiple types of instances, in his case he is accessing instance methods on the singleton (or anonymous class or eigen, however you want to label it) vs instance methods on /an/ instance of that object. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

class A
def self.b
print "this is static methods"
end
end
You can only be able to call the method "b" by using : A.b
that wat I am trying to say.
