title: Laravel - saving multiple models
body: <p>Hy guys, i have a post table and a tags table also a post_tag pivot table in my DB.</p>
  
  <p>Everything works just fine, when i want to save a new post with one tags using this method:</p>
  
  <pre><code>$post-&gt;tags()-&gt;save($tag)
  </code></pre>
  
  <p>But when i have multiple tags, then of course the save method dies.
  So my question is how can i save multiple tags ?</p>
