I have a module with a class variable in it
module Abc
@@variable = "huhu"
def self.get_variable
@@variable
end
class Hello
def hola
puts Abc.get_variable
end
end
end
a = Abc::Hello.new
a.hola
Is it possible to get @@variable
inside Hello
without using get_variable
method? I 开发者_高级运维mean something like Abc.variable
would be nice. Just curious.
You cannot access @@variable
directly (i.e., Abc.variable
) within the scope of the Hello
class in the module Abc
. Why? Because, when the Ruby interpreter sees something like Abc.variable
, it would think variable
as class/module method of Abc.
It is important to think the Ruby way when programming in Ruby.
try this
Abc.class_variable_get(:variable)
