hop of those help? Good question, but....before getting too far into this, make sure to check out Arrow's Impossibility Theorem.
Other than having a great name, it states that it is impossible to create a rating or voting system that is "fair". That is, any rating system can be shown to violate at least one of a series of common sense rules. The Wikipedia article is pretty good, but I'm sure you can find other descriptions of the problem. A great introduction to social choice theory, too.

wish help you to fix your issue It's not hard to roll your own, you just need a combination of jQuery/AJAX, CSS and the server-side poison of your choice.
Here is an example: http://www.99points.info/2010/05/ajax-rating-system-create-simple-ajax-rating-system-using-jquery-ajax-and-php/

wish of those help You are missing a table in your database (probably required by the gem). Are you sure you have migrated your database?
You must run the script which probably generates migrations, but then you must also:
code :
rake db:migrate
script/generate ajaxful_rating UserModelName
script/generate authenticated user sessions
script/generate ajaxful_rating user
Rating system giving wrong rating when clicked repeatedly

wish helps you As you are updating the same row (of the same table corresponding to the same id) for all the parameters, i.e. hits, rating, rating_total, why don't you just try doing it in a single update query. Then the transaction will be completely atomic and you don't have to worry abt one query passing and the other getting failed.
This should be your single update query:
code :
UPDATE $tablename SET user_rating='$new_round_rating', hits='$new_hits',rating_total='$new_rating_total'   WHERE id='$id'
Convert rating to percentage in 5 star rating system

Convert rating to percentage in 5 star rating system

I hope this helps you . If your goal is to get the percentage of ratings that are (for example) 1-star, then just divide star1 by the number of ratings (which I guess is tot_stars, although the name seems to imply otherwise). That gets you a proportion; multiply by 100 to get a percentage.
So, for example, letting the database do the math:
code :
SELECT star1, star1 * 100 / tot_stars AS percent1, 
       star2, star2 * 100 / tot_stars AS percent2, 
       star3, star3 * 100 / tot_stars AS percent3, 
       star4, star4 * 100 / tot_stars AS percent4, 
       star5, star5 * 100 / tot_stars AS percent5
  FROM starsTable
<?php     
// Example data
$star1 = 1;
$star2 = 5;
$star3 = 7;
$star4 = 10;
$star5 = 8;

$tot_stars = $star1 + $star2 + $star3 + $star4 + $star5;

for ($i=1;$i<=5;++$i) {
  $var = "star$i";
  $count = $$var;
  $percent = $count * 100 / $tot_stars;
  for ($j=1;$j<=5;++$j) {
    echo $j <= $i ? "☆ " : "  ";
  }
  printf("\t%2d (%5.2f%%)\n", $count, $percent,2);
}
?>
☆            1 ( 3.23%)
☆ ☆          5 (16.13%)
☆ ☆ ☆        7 (22.58%)
☆ ☆ ☆ ☆     10 (32.26%)
☆ ☆ ☆ ☆ ☆    8 (25.81%)

Prepare 2 image files, one has 5 empty-stars and the other has 5 filled-stars, just like:
code :
  <html>
  <head><title>test</title>
      <style type="text/css">
        .container > * {
            position: absolute;
        }

        .container, .crop {
            height: 70px;
        }

        .crop {
            overflow: hidden;
        }
    </style>
  </head>
  <body>
    <div class="container">
        <img src="https://i.stack.imgur.com/yiT2y.png" />
        <!-- the width could be calculated either at server or client side, or define in css -->
        <div class="crop" style="width:280px">
            <img src="https://i.stack.imgur.com/oTi9e.png" />
        </div>
    </div>
 </body>
