When i use live search show an extra output format

Hi guys, i've been looking for some "light" for this problem, but honestly i dont know where i can find some information about this.

I'm using ajax for a live search, so everything works fine.

View:

<form id="live-search-form" method="get" action="<%= search_path %>">   <input id="big-search-box" name="q" type="text" autocomplete="off"/> </form>

<div id="live-search-results"></div>

Controller:

  def live_search

    @lafnuevas = Lafnueva.search params[:q], :page => params[:page], :per_page => 1000     render :partial => 'filtrado'

  end

Application.js:

$(document).ready(function(){   $('#big-search-box').bind('keyup',function() {

    var form = $('#live-search-form'); // grab the form wrapping the search bar.       var url = '/lafnuevas/live_search'; // live_search action.     var formData = form.serialize(); // grab the data in the form

    $.get(url, formData, function(html) { // perform an AJAX get        $('#live-search-results').html(html); // replace the "results" div with the results

      });

  });

});

But when i display the information i get the extra content that is the result of my query:

[#<Lafnueva id: 80091, captura: "71", fechac: "1997-02-04 00:00:00", titulo1: "L'ATLAS CURIEUX OU LE MONDE ... / DRESSé ET DEDIé..."

And after that i have my partial without problem.

Somebody can help me for dont display the extra content i've been looking for the problem and perhaps everything for solve the problem is in this line in application.js :        $('#live-search-results').html(html); // replace the "results" div with the results

but the other options dont work fine (val,text), and when i inspect the element the extra content appear between quotes (").

Thanks in advance.
