But I don't know how to do that or is it even possible Note: I want to use django admin. -

Return some variables from a function in views.py to a js file with render and POST - Django
Since some days I'm trying to execute a python function from my js file. I'm doing it with Ajax. For now, I'm executing the function and passing some values with POST but I can recover this info. This is my function inside views.py def vista_sumar(request): ctx = 'none' if request.method == 'POST': a = request.POST['a'] b = request.POST['b'] c = int(a) + int(b) ctx = {'Result':c} print('sss',ctx) return render(request,'main.html',ctx) I know the call to this function is working because in the js file a=3 and b=1 and it always print sss {'Result': 4} but then it never comes back to the js. I try it too with return HttpResponse(c) and the behaviour is better because arrive something to the js but it is undefined. Can't I use render in this situations? Can somebody help me, please? My js is: $('#prueba').click(function() { alert('boton pulsado'); var csrftoken = $("[name=csrfmiddlewaretoken]").val(); alert(csrftoken) a =1; b =3; $.ajax({ url: '/../../prueba/', type: 'POST', headers:{"X-CSRFToken": csrftoken}, data: { 'a': a, 'b': b, }, dataType: "json", cache: true, success: function(response) { console.log(response.Result); alert(response.Result); } }); alert('fin') }); With return HttpResponse(c) the console.log and the alert show undefined. Thank you very much. -
