Call to undefined method Database_MySQLi_Result::delete()
<p>I'm using Kohana and I'm trying to delete some data in my database. So, I made a request like this : </p>

<pre><code>    $env_sol = ORM::factory('EnvironnementSol')
        -&gt;where('sol_id','=',$id)
        -&gt;and_where('environnement_id','=', $id_environnement-&gt;id)
        -&gt;find_all();

    $env_sol-&gt;delete();
</code></pre>

<p>And I run the page, it tells me : </p>
