# Django admin sets default form field values based on GET parameters

<div class="document">


<p>When you pass a GET query like</p>
<pre class="literal-block">?name=hoge&amp;url=fuga
</pre>
<p>to the Django admin's new record addition page, it will pre-fill the corresponding fields with these default values.</p>
<p>This works well with bookmarklets.</p>
<p>For example, you can create a bookmarklet like this:</p>
<p><a class="reference external" href="javascript:window.open('https://example.com/admin/spamapp/eggmodel/add/?title='+encodeURIComponent(document.title)+'&amp;url='+encodeURIComponent(location.href),'_blank','width=800,height=600,menubar=no,toolbar=no,resizable=yes,scrollbars=yes');void(0">javascript:window.open('https://example.com/admin/spamapp/eggmodel/add/?title='+encodeURIComponent(document.title)+'&amp;url='+encodeURIComponent(location.href),'_blank','width=800,height=600,menubar=no,toolbar=no,resizable=yes,scrollbars=yes');void(0</a>);</p>
<p>or something similar.</p>
