Dynamically add conditions to a rule

[anirudh-dasu]

Hi,

I have a situation where I need to generate conditions for the rule dynamically based on the user input. For example, this is what am trying to do.

def convert(title, variables)
  engine.rule title do |variables|
    forall {
      has :_, :id, :Id
      variables.each do |v|
        has :Id, v.downcase.to_sym, v.capitalize.to_sym
      end
    }
  end
end 

Similarly for other matchers after has, I want to dynamically set them. However seems like I can't pass any of my variables into the rule block. Is there anyway of doing this? Can I extend the DSL for this functionality? Based on the documentation, it seems that the DSL extension is only for actions. Thanks.
