  <p>I'm new to Django!</p>
  <p>I'm using Django Admin. How can I make a new button(near save,...) and post the information and use it in a python script(I am using Django version 2).</p>
  <p>admin.py:</p>
  <pre><code>admin.site.register(Router)
  admin.site.register(Peer, PeerModelAdmin)
  admin.site.register(Prefixe, PrefixModelAdmin)
  </code></pre>
