Redirect user to modal popup after registration confirmation using Devise on Rails 4.x webapp

Question

On a Rails 4.x app I'm using Devise to register users. What I want to do is redirect a user after confirmation to the usual user_path(resource) but having a modal appear to prompt for a few things. I don't know how to solve this without using cookies and javascript. Anyone solved this before or know to do it using the standard after_confirmation_path_for way in Devise? If not, what do you think is the best approach to solve it?

Many thanks in advance.

out of the hat idea, pass additional param in your path helper, if param.present? -> show modal — mmln, Jan 18 '15 at 18:00
thanks @mymlyn , yeah, that's what I'll do with javascript if there's no Railsy idiomatic way of doing this. — Slenny, Jan 19 '15 at 11:18

Ok, so if anyone else runs into this problem. I only found one way to solve it, this is it:

confirmations_controller.rb

class ConfirmationsController < Devise::ConfirmationsController

  private

  def after_confirmation_path_for(resource_name, resource)
    sign_in(resource)
    user_path(resource[:id], cp: true)
  end
end

Then in the view which I want to popup the modal, I used this fairly popular javascript answer (How can I get query string values in JavaScript?) show.html.erb:

<%= javascript_tag do -%>
window.onload = function() {
    var doCP = getParameterByName('cp');
    if (doCP) {
        $("#modal").html("<%= escape_javascript(render 'confirm_prompt_form') %>");
        $("#modal").modal("show");
    }
}

function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
