Question

Imagine an array of strings ["User","Article","Image"], what’s the best way of evaluating their class declarations into the current scope? I’m imagining something like:

array.each do |element|
  instance_eval<<EOF
    class #{element} < ActiveRecord::Base
    end
EOF
end

Is this the proper way of doing it?

Answer 1

How about this?

array.each do |element|
  Object.const_set(element, Class.new(ActiveRecord::Base))
end
