Dynamically chain class methods

Rails
1

Hi all,

I was wondering if it is possible to dynamically chain class methods in
rails. Suppose there are several optional methods that a class may have,
I
want to chain call all the methods that apply to a certain class. Is it
possible? What is the best approach to do achieve this?

Thanks in advance.

ActiveSupport::Callbacks ?

ActiveSupport defined Module#alias_method_chain which is used
extensively to do what I think you are asking for.

Googling alias_method_chain should fill you in on the details.
