To get the class name:
class User
def call = puts self.class.name
end
User.new.call #=> User
This will work even if the name is namespace inside a module:
module Authenticated
class Visitor
def call = puts self.class.name
end
end
Authenticated::Visitor.new.call #=> Authenticated::Visitor
Will not work if you call class.name
module Authenticated
def self.call = puts self.class.name
end
Authenticated.call # will return Module!!
But Module defines an accessor named name
module Visitors
def self.call = puts self.name
end
Visitors.call # will return Visitors
Yes there is a constant name defined on a Module.
You can of course redefine that if you want:
module Guest
def self.name = "Another name"
def self.call = puts self.name
end
Guest.call # will return "Another name"
Use __method__ for that:
class Admin
def call(...) = puts __method__
end
Admin.new.call # "call"
