title: Do I need to use "Marking extra actions for routing" in this REST Django API?
body: <p>I'm currently having this issue. I have to set up an URL like this:</p>
  <pre><code>.../users/&lt;user_id&gt;/user_action/
  </code></pre>
  <p>There are many <strong>users</strong> and when I pick <strong>one user</strong> (with user_id), I will be able to see the user's information. Then, go to /user_action, I will be able to POST actions for that specific user.</p>
  <p>In this case, do I have to use the <a href="https://www.django-rest-framework.org/api-guide/viewsets/#marking-extra-actions-for-routing" rel="nofollow noreferrer">Marking extra actions for routing</a> or do I just need to make a separate Viewset for user_action (then link it to users/&lt;user_id&gt;/ in the urls.py)?</p>
