Ruby on Rails - IP Limit

Question

I'm new to rails, so easy. I created a blog with the ability to "vote" for a post using a feature similar to Facebook. I do not use authentication, but I want to limit the voting at a specific post by IP. That is, as soon as someone votes for a message, they cannot vote again (unless they reset their router, of course).

I feel that it must be something that I touch upon, changing the voices or messages of the Model, but I am afraid that it is connected with Sessions, which ... I have no experience yet.

Let me know if you need me to post any code. Here is the voice controller.

class VotesController < ApplicationController

  def create
    @post = Post.find(params[:post_id])
    @vote = @post.votes.create!(params[:vote])

       respond_to do |format|
       format.html { redirect_to @post}
       format.js
     end
  end
end

      end
    end
  end
