RE: Error at the return of an AJAX POST in DJANGO

Walter,

 

If your copy and paste is accurate you have too many closing brackets in the ajax section.

 

Try removing one of these from the end of the ajax section:

    });

Hi buddies, I have a POST request from ajax. At the backend some records are updated in the django view, this is done fine but an error comes up and the page isnt reloaded.

 

**This is the error:**

 

> SyntaxError: Unexpected token O in JSON at position 0

 

**This is the ajax:**

 

    $.ajax({

    headers: { "X-CSRFToken": token },

    "url": '/articulos/massup/', "type": "POST",

    "dataType": "json", data: data,

    success: function(e){

    if(e="OK"){

    location.reload(true);

    }

    },

    error: function(a,b,c){

    alert(c);

    }

    });

    });

 

**Thi is the view:**

 

    @csrf_exempt

    def massup(request):

        template_name = "articulos/articulos_ok.html"  

        contexto={}  

        if request.method=="GET":  

            cat = Articulos.objects.all().order_by("codigo")  

            contexto={"obj":cat}  

        if request.method=="POST":  

            codigos=request.POST.getlist("codigos[]")

            porcentaje = codigos[0]#el primer elemento de la lista es el porcentaje

            porcentaje=Decimal(porcentaje)

            codigos= [int(x) for x in codigos]#Convierte la lista en integer

            art_change = Articulos.objects.filter(pk__in=codigos)

            i=0

            for item in art_change:

                if i!=0: #Excluye el primer item ( el porcentaje)

                    precioant=item.precio

                    precionuevo=(precioant + (porcentaje * precioant/100))

                    item.precio=precionuevo

                    item.save()

                i=i+1

            return HttpResponse("OK")

        return render(request
