How do I convert hash keys to method names?

Question

This is my hash:

tempData = {\"a\" => 100, \"here\" => 200, \"c\" => \"hello\"}

I need to access the hash keys as a method like:

Answer 1

you can extend the Hash class in the following way.

class Hash
      # return nil whenever the key doesn't exist
      def method_missing(m, *opts)
        if self.has_key?(m.to_s)
          return self[m.to_s]
        elsif self.has_key?(m.to_sym)
          return self[m.to_sym]
        end
        return nil

        # comment out above line and replace with line below if you want to return an error
        # super
      end
end
