Question

I am trying to send a serialized object using JSON. Here is my view code:

if request.is_ajax():
        resp = {}
        if request.POST:
            if form.is_valid():
                g = form.save()
                resp['graph'] = serializers.serialize('json', [g, ])
                resp['success'] = True
            else:
                resp['errors'] = form.errors
                resp['success'] = False
            return HttpResponse(simplejson.dumps(resp), mimetype='application/javascript')
        return render(request, 'graph/inlines/create.html', {'form':form})

The problem is (rather obviously) that the ‘graph’ object I am trying to return is being serialized twice (once with serializers.serialize and again when I used simplejson.dumps) and the object is being received as a json string.

I tried just doing this:

resp['graph'] = g

But it throws a server error as the object obviously isn’t serialized when I try to use simplejson.dumps.

Is there a way I can tell it to ignore this key when dumping the data? Would appreciate any help.

Rather than serializing the graph queryset to json the first time, use serializers.serialize('python', g) to convert it to a Python dictionary first. Then the whole thing will be converted to json at the end.
