Error at the return of an AJAX POST in DJANGO

[Walter Randazzo]

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

Not sure, but looks like an extra closing bracket in line 9 of the ajax code

I'm not a JS expert, but is your success function defined properly?
if(e="OK") vs. if(e=="OK")

HI Macolm,

I am checking out  the response value in the  and it shows OK in the browser dev tool . So i guess the function is not defined properly....

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:

    });

I tried with no luck. When i remove it  it brings an error.

[Malcolm MacKinnon]

In your success function, you are assigning the variable e = 'OK', so in your if statement, it appears to throw an error. If you change it to  if(e=="OK"), does it work? Note the two equal signs, == .

HI Mac,

I've changed the if statement  to if(e=="OK")  but  the message error persist.

Note: I have explore the value of the return in the webbrowser dev tools and it contains "OK"
