problem with django model method save()

[rafiee.nima]

Hi Im some how new to django . I write a view to handle ajax request

but I find out that save() method dose not save model instance in to the database

here is my code 

def add_room(request):

    context={}

    status=''

    if request.is_ajax:

        if request.POST:

            hotel_instance=Hotel.objects.get(id=request.POST['hotel'])

            room_id=int(request.POST['id'])

            if room_id > 0 :

                room=HotelRoom.objects.get(id=request.POST['id'])

                room.hotel=hotel_instance

                room.number=request.POST['number']

                room.bed_count=request.POST['bed_count']

                room.ground_sleep=request.POST['ground_sleep']

                room.view=request.POST['view']

                room.reserved=request.POST['reserved']

                room.tv=request.POST['tv'].capitalize()

                room.phone=request.POST['phone']

                room.refrigerator=request.POST['refrigerator']

                room.air_condition=request.POST['air_condition']

                room.toilet=request.POST['toilet']

                room.creator=request.user

                room.save()

                room_json=model_to_dict(room)

                status="room successfully updated"

            else:

                room = HotelRoom(

                    hotel=hotel_instance,

                    number=request.POST['number'],

                    bed_count=request.POST['bed_count'],

                    ground_sleep=request.POST['ground_sleep'],

                    view=request.POST['view'],

                    reserved=request.POST['reserved'],

                    tv=request.POST['tv'],

                    phone=request.POST['phone'],

                    refrigerator=request.POST['refrigerator'],

                    air_condition=request.POST['air_condition'],

                    toilet=request.POST['toilet'],

                    creator=request.user )

                room.save()

                status="new room successfully added "

        raw_data={'status':status,'data':room_json}

        data=simplejson.dumps(raw_data)

        return HttpResponse(data, mimetype="application/json")

I don't see why wouldn't your model's .save() work, maybe we'd need to see the model code, but I know you probably want to read this:

https://docs.djangoproject.com/en/dev/topics/forms/modelforms/

once you've implemented a ModelForm, you'd pretty much would just do

form = RoomForm(request.POST)
if form.is_valid():
  form.save()
