I saw that now in Django 1.7 I can use the http.JSONResponse
object to send JSON to a client. My View is:
#Ajax
def get_chat(request):
usuario = request.GET.get('usuario_consultor', None)
usuario_chat = request.GET.get('usuario_chat', None)
mensajes = list(MensajeDirecto.objects.filter(Q(usuario_remitente = usuario, usuario_destinatario = usuario_chat) | Q(usuario_remitente = usuario_chat, usuario_destinatario = usuario)))
return JsonResponse(mensajes, safe=False)
But I get the next error:
<MensajeDirecto: Towi CrisTowi> is not JSON serializable`
Do you know how to serialize a QuerySet to send it back in JSON form?
You shouldn't re-serialize with JsonResponse
. You'll get a correctly formatted JSON response with:
from django.core import serializers
from django.http import HttpResponse
def my_view(request):
my_model = MyModel.objects.all()
response = serializers.serialize("json", my_model)
return HttpResponse(response, content_type='application/json')
If you use a JsonResponse
, it will coerce the already serialized JSON to a string, which is probably not what you want.
Note: Works with Django 1.10
