title: Django, insert two serialized objects models inside of custom json
body: <p>I need insert two json serialized models inside custom json</p>
  
  <p>I tried using json.dumps but the vars (objects1, objects2) converts in string</p>
  
  <pre><code>objects1 = Objects1.objects.all()
  objects2 = Objects2.objects.all()
  
  json_objects1 = serializers.serialize("json", objects1)
  json_objects2 = serializers.serialize("json", objects2)
  
  data = json.dumps("first_objects": json_objects1, "second_objects":json_objects2)
  
  return HttpResponse(data, content_type="application/json; charset=utf-8")
  </code></pre>
