  <p>This happens when I am calling the following model:</p>
  
  <pre><code>class NewsResource(ModelResource):
      class Meta:
  
          queryset = News.objects.select_related('picture').all()
          allowed_methods = ['get','patch']
          include_resource_uri = False
          include_absolute_url = False
          authentication = ApiKeyAuthentication()
          authorization = DjangoAuthorization()
  </code></pre>
  
  <p>Any ideas?</p>
