Hi guys,
I have a method inside a controller that has many lines of code (some of
them used to generate/read cookies).
In order to keep the code readable and use the object-oriented power of
Ruby, I created a foreign class that I call in my method using:
def index
require(''foreign_class'')
f = Foreign.new
@out = f.foreign_method
end
The problem is, when the foreign_method tries to create a cookies with
cookies[:c] = ''id''
it says "undefined local variable or method ''cookies''
So... it''s not possible to handle cookies in foreign classes. Or
it''s
not even supposed to use foreign classes in Ruby?
Thanks a lot.

I mean: f = Foreign.new :cookies => cookies Keep smiling yanosz --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

The reason cookies isn''t available in your "foreign" class is that cookies is a method of the controller (inherited from ActionController::Base). This is to be expected since objects provide separate namespaces for methods and instance variables; that''s a pretty fundamental part of what it means to be object oriented. Also, working in an OO language does not necessarily imply that creating a new object class is the best approach in all cases. For what you seem to be trying to do, I''d recommend using a module (a.k.a. mixin) that you include in your controller class. A module''s methods have access to all the methods and instance variables of the class in which it is included, such as the cookies method.> Thanks a lot.--Greg --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
