Laravel 5.2 - How to set random id for Eloquent table
<p>I have a test table :</p>

<pre><code>    public function up()
{
    Schema::create('besttts', function (Blueprint $table) {
        $table-&gt;string('id')-&gt;primary()-&gt;index();
        $table-&gt;string('tests')-&gt;nullable();
        $table-&gt;timestamps();
    });
}
</code></pre>

<p>How i can make the 'id' not to be increment and autofilled?</p>
