title: Get a related profile via request.user in django 1.8+
body: <p>I have a Profile model:</p>
  <pre><code>class Profile(models.Model):
      user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name=&quot;profile_user&quot;)
      preferred_name = models.CharField()
      # more profile fields
  </code></pre>
  <p>that I want to access in a template via the user: <code>{{request.user}}</code></p>
  <p>However <a href="https://stackoverflow.com/questions/13460426/get-user-profile-in-django">previous answers</a> to this question use a method that was <a href="https://docs.djangoproject.com/en/dev/releases/1.7/" rel="nofollow noreferrer">removed in 1.</a>7:</p>
  <blockquote>
  <p>&quot;These features have reached the end of their deprecation cycle and so have been removed in Django 1.7:</p>
  <ul>
  <li>The AUTH_PROFILE_MODULE setting, and the get_profile() method on the User.&quot;</li>
  </ul>
  </blockquote>
  <p><a href="https://docs.djangoproject.com/en/1.8/topics/auth/customizing/#extending-the-existing-user-model" rel="nofollow noreferrer">The docs</a> now say I should just do this, but it doesn't return anything:</p>
  <p><code>{{request.user.profile.profile_field_i_want}}</code></p>
  <p>the only difference I can see between the example and my profile model is that I use <code>settings.AUTH_USER_MODEL</code> but the example uses <code>User</code> as the OneToOne.</p>
  <p>However if I: <code>print(settings.AUTH_USER_MODEL)</code> the result is <code>auth.User</code></p>
  <p>I also confirmed that the users actually have profiles.</p>
  <p>How do I access a user's related profile via request.user?</p>
