I have implemented ordering in a generic ListView: class CarList(LoginRequiredMixin, ListView): model = Car paginate_by = 30 ordering = 'car_id_internal' def get_ordering(self): return self.request.GET.get('ordering', 'car_id_internal') def get_context_data(self, *args, **kwargs): context = super(CarList, self).get_context_data(*args, **kwargs) context['current_order'] = self.get_ordering() return context And in my template: <thead> <tr> <th><a href="{% url 'car_list' %}?ordering=car_id_internal">Internal car ID</a></th> <th><a href="{% url 'car_list' %}?ordering=type">Type</a></th> <th><a

models.py class Category(models.Model): name = models.CharField(max_length=50) class SubCatergory(models.Model): parent_category = models.ForeignKey(Category) name = models.CharField(max_length=100) views.py def all_products(request): c = Category.objects.all() s = SubCatergory.objects.all() return render_to_response('all_products.html', {'c':c, 's':s}) all_products.html {% for category in c %} <h1>{{ category.name }}</h1> <ul> {% for sub in s %} {% if category.id == sub.parent_category.id %} <li>{{ sub.name }}</li> {% endif %} {% endfor %} </ul> {% endfor %} Just wondering if above is best

I'm trying to write a functional test that uses Selenium to test a Django view. When the user comes to a page ("page2"), the view that renders that page expects to find a session variable "uid" (user ID). I've read a half dozen articles on how this is supposed to be done but none of them have worked for me. The code below shows how the Django documentation says it should be done but it doesn't work for me either. When I run the test, the view never completes executing and I get a "server error occurred" message. Could someone please tell me what I'm doing wrong? Thank you. views.py: from

I am getting no attribute 'object' error' here is views.py class CheckoutView(FormMixin , DetailView): model = Cart template_name = "carts/checkout_view.html" form_class = GuestCheckoutForm def get_object(self , *args , **kwargs): if self.request.user.is_authenticated(): try: cart = Cart.objects.get(user__username=self.request.user) except: cart = None if cart == None: HttpResponseRedirect(reverse("cart")) else: cart_id = self.request.session.get("cart_id") if cart_id == None: HttpResponseRedirect(reverse("cart")) cart = Cart.objects.get(id=cart_id) return cart def get_context_data(self ,*args

I know there are similar questions (like this , this , this and this ) but I have specific requirements and looking for a less-expensive way to do the following (on Django 1.10.2): Looking to not have sequential/guessable integer ids in the URLs and ideally meet the following requirements: Avoid UUIDs since that makes the URL really long. Avoid a custom primary key. It doesn’t seem to work well if the models have ManyToManyFields. Got affected by at least three bugs while trying that ( #25012 , #24030 and #22997 ), including messing up the migrations and having to delete the entire db and

So I'm working with django and file uploads and I need a javascript function to execute after the file has been uploaded. I have a file upload handler in my views.py which looks like this: def upload_file(request): form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): for f in request.FILES.getlist('fileAttachments'): handle_uploaded_file(f) return HttpJavascriptResponse('parent.Response_OK();') else: return HttpResponse("Failed to upload attachment.")
