title: Django REST serializer: create object without saving
body: <p>I have started to play with the Django REST framework. What I am trying to do is to POST a request with some JSON, create a Django Model object out of it, and use the object without saving it. My Django model is called SearchRequest. What I have is:</p>
  
  <pre><code>@api_view(['POST'])
  def post_calculation(request):
      if request.method == 'POST':
          #JSON to serializer object
          serializer = SearchRequestSerializer(data=request.data)
          if (serializer.is_valid() == False):
              return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
          mySearchRequestObject = serializer.save()
  </code></pre>
  
  <p>This does create a SearchRequest object, however saves it into the database right away. I would need it without saving.</p>
