title: flask-admin queryset analog from django-admin
body: <p>I'm using SQLAlchemy ModelView</p>
  
  <p>Well, I'm trying to manage per-item permissions in my admin. So, users can change only that model instances, they created.</p>
  
  <p>I can add column "author" with relation to "User" table.</p>
  
  <p>After that, in django-admin typically we use</p>
  
  <pre><code>def queryset:
      qs = super(...
      qs = qs.filter(author = request.user)
      return qs
  </code></pre>
  
  <p>So, how to do this in flask-admin. Mb, it's definitely another way, and maybe there is "queryset" analog?</p>
