Update Database Using AJAX in Django

Question

So I have an AJAX command, which passes information to a views.py method (I have verified that the passing works from the HTML->urls.py->views.py, so that's all good), but once I have it in "views.py", I have no idea how to get it to update in the database itself.

I have tried to avoid using a forms.py file if possible, but if that is the only option I'll bend to it.

The AJAX function is as follows:

$.ajax({

    url : '/perform/acts/update/{{  act.id  }}/',

    type : "POST",

    data : {

        'csrfmiddlewaretoken' : "{{  csrf_token  }}",

        furtherData : furtherData

    },

    success : function(result) {}

});

The views.py function is...so far, lacking, to say the least, but this is where I'm sort of lost:

def update_act(request, furtherData_id):

    if request.method == 'POST':

      ?

      return HttpResponse(?)

A big reason for doing this this way was performing updates without reloading and without having to add another module. I have been using Django for only a couple weeks, so it could be something easy that I'm missing...

Any help much appreciated!

Your view function:

def my_view_action(request, any_pk_id):
    from django.http import JsonResponse
    if request.method=='POST' and request.is_ajax():
        try:
            obj = MyModel.objects.get(pk=any_pk_id)
            obj.data_attr = request.POST['attr_name']
            obj.save()
            return JsonResponse({'result': 'save successfully'})
         except MyModel.DoesNotExist:
            return JsonResponse({'error': 'Object does not exist'})
     else:
         return JsonResponse({'result':'Not a valid request'}
