Kohana Model Saved Twice - php

Question

I just installed a fresh copy of Kohana 3.2, built my database, wrote my first model, and tried testing it. Everything works fine except the model's "save" method is being executed twice--I end up with two new entries in the database instead of one. The problem only occurs when I use the "find" code shown below.
Why would the model's save get executed twice, once as expected and once because of the find?
Here's the code:
class Controller_Welcome extends Controller {
public function action_index()
{
$rating = ORM::factory('rating');
$rating->user_id = 1;
$rating->userlevel_id = 3;
$rating->category_id = 1;
$rating->page_id = 1;
$rating->rating = 4;
$rating->comments = 'This one is a real killer';
$rating->ratingstatus_id = 1;
$rating->save();
$found = ORM::factory('rating')
->where('id', '=', 1)
->find();
$this->response->body($found->comments); // Test to check for found data
}
} // End Welcome
Thanks in advance!

Answer 1

There are two issues that were causing my problem:
I didn't have a favicon.ico on my server. Many browsers request one, and all URLs that aren't actual files or directories get redirected to the index page. Every time I loaded the page, the browser would request a missing favicon and get redirected to my index page--two requests. After looking at my logs, this page was what tipped me off: http://forum.kohanaframework.org/discussion/7447/error-kohana_request_exception/p1
After I added a favicon, I still saw the double request behavior occasionally. It turns out it was a behavior of Google Chrome--Chrome prefetches pages, so each time I changed the content, Chrome would prefetch and cache the page (adding a request).
After adding a favicon and when using a browser besides Chrome, everything behaves as expected.

$rating = ORM::factory('rating');
This line represents nothing.
If you want to create new record you should use create() instead save().
$rating = new Model_Rating;
$rating->user_id = 1;
$rating->userlevel_id = 3;
$rating->category_id = 1;
$rating->page_id = 1;
$rating->rating = 4;
$rating->comments = 'This one is a real killer';
$rating->ratingstatus_id = 1;
$rating->create();
If you want to load single rating object with given id:
$found = ORM::factory('rating', 1);
