Question

I want to send few dictionaries from django to android through HTTP after getting query in HTTP get. How can I do this and what formatting should I use?
I currently respond using HttpResponse. Name of keys are constant.

Read about serializing objects in django.

You can choose between xml, json or yaml. It’s pointless to add documentation here. Goto the link.

EDIT: Django’s doc is really nice. Example shouldn’t really be needed. But, still, an example from one of my projects [Line 492-507 from views.py].

def pendingOrders(request):
    userprof = UserProfile.objects.get(user= request.user)
    if userprof.is_student:
        student_account = request.user
        dish = Dishes.objects.all()
        #Getting all pending orders
        order_all_pending = Orders.objects.filter(student_id = student_account,delivered = False)
        pending_orders = Orders.objects.filter(~Q(status = 2),delivered = False)
        for order in order_all_pending:
            #Hack to change QuerySet to pass as JSON 
            order.quantity = pending_orders.filter(id__lt = order.id,counterid= order.counterid).count() + 1

        #Returning JSON response to the objects obtained in above statement
        return HttpResponse(serializers.serialize('json',order_all_pending,use_natural_keys=True),mimetype='application/json')
    else:
        return HttpResponse("Something went wrong")
