Question

In my app, I have a Model which should include a module. The model has an attribute called ‘format’, which determines which module should be included. For instance, if format == 0, then the Model should include SingleElimination, whereas if format == 1, then the Model should include DoubleElmination. What is the best way to do this?

Answer 1

def include_format
  case format
  when 1
    extend SingleElimination
  when 2
    extend DoubleElmination
  end
end

after_initialize :include_format
