Ruby on Rails and Ajax - persist the data from the database in a button
===

I am using a button-group as a radio button to capture user input for a boolean field in my database. I have a wedding model with a boolean field :rsvp. The form below seems to capture the data.  However, if I refresh the page, the button is no longer toggled with the user's choice.  My question is, how to I get the button to persist the user's choice, even if the page is refreshed, or if the user logs out and logs in again?

**Models**

     class User < ActiveRecord::Base
      has_one :wedding
     end

     class Wedding < ActiveRecord::Base
      belongs_to :user
     end

**Controllers**

     class WeddingsController < ApplicationController

       def new
         @wedding = Wedding.new
       end

       def create
         @wedding = current_user.build_wedding(params[:wedding])
          if @wedding.save
           redirect_to root_path
         else
           render 'new'
         end
       end

     class StaticPagesController < ApplicationController
       def home
  	    @wedding = Wedding.new
       end


**View:**

home.html.erb

      <%= form_for(@wedding, :remote => true) do |f| %>
	     <div class="btn-group-wrap">
		      <div class="btn-group" data-toggle="buttons-radio">
			     <%= f.button 'Yes', :class => "btn btn-large btn", :value => "1", :name => "wedding[rsvp]" %>
			      <%= f.button 'No', :class => "btn btn-large btn", :value => "0", :name => "wedding[rsvp]" %>
	   	      </div>
	     </div>
      <% end %>
