Question

I am trying to make Django view that will give JSON responce with earliest and latest objects. But unfotunately it fails to work with this error.

'str' object has no attribute '_meta' 

I have other serialization and it works.

Here is the code.

def get_calendar_limits(request):     result =  serializers.serialize('json', Session.objects.aggregate(Max('date'), Min('date')), ensure_ascii=False)     return HttpResponse(result, mimetype='application/javascript') 

Thanks a lot beforehand.

Answer 1

Take a look at the following:

objects= Session.objects.aggregate(Max('date'), Min('date')) print [ type[o] for o in objects ] result =  serializers.serialize('json', objects, ensure_ascii=False) 

You might want to just run the above in interactive Python as an experiment.

What type are your objects? Is that type serializable?
