Refactoring ActiveRecord models with a base class versus a base module

Question

Class A and B are identical:

class A < ActiveRecord::Base
 def foo
  puts \"foo\"
 end
end

class B < ActiveRecord::Base
 def foo
  puts \"foo\"
 end
end
<         


        

Answer 1

Both of these methods will work. When deciding to use a module or a class, the question I have is does the class fit into the object hierarchy, or are these just methods I am looking to reuse. If I am just trying to factor out common code for DRY reasons, that sounds like a module. If there really is a class that fits into the hierarchy that makes sense on its own, I use a class.

Coming from a Java background, it is refreshing I can choose to make these decisions.
