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

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, == .

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
