Lately I am moving from method based views to the class based views in Django. I feel that I couldn't find a good solution to use ListView together with forms. Below code in new view works but pagination does not work. Where I am doing wrong? Also, what do you think new view? Is there another and cleaner way to do that? Old method based view: def list_orders(request): if request.method == 'POST': form = billing_forms.OrdersForm(request.POST) object_list = orders.list_orders_by_date( owner=request.user, year=form.data.get('year'), month=form.data.get('month') ) else: form = billing_forms.OrdersForm() object_list = billing_orders.list_orders(owner=request.user) page = request.GET.get('page', 1) paginator = Paginator(objects_list, 10) try: object_list = paginator.page(page) except PageNotAnInteger: object_list = paginator.page(1) except EmptyPage: object_list = paginator.page(paginator.num_pages) return shortcuts.render(request, 'billing/orders.html', { 'object_list': object_list, 'form': form, }) New class based view: class OrdersListView(ListView, BaseLoginRequiredMixin): template_name = 'billing/orders.html' paginate_by = 10 def get(self, request, *args, **kwargs): form = billing_forms.OrdersForm() object_list = billing_orders.list_orders(owner=request.user) return shortcuts.render(request, self.template_name, {'form': form, 'object_list': object_list}) def post(self, request, *args, **kwargs): form = billing_forms.OrdersForm(request.POST) object_list = billing_orders.list_orders_by_date( owner=request.user, year=form.data.get('year'), month=form.data.get('month'), ) return shortcuts.render(request, self.template_name, {'form': form, 'object_list': object_list}) -
Django postgres model changes
After changing a model attribute from "owner" to "user" im getting this error message: column app_modelName.user_id does not exist LINE 1: SELECT "app_modelName"."id",... when trying to make a request to the endpoint. The migrations went through, and also deleting the migrations and doing fake migrations didn't help. When I looked up the table in my Postgresql is discovered that the column is still named owner_id and not user_id. Any idea how I can change that ? -
django booleanfield is None instead of False
i' ve a new application with the following model definition: class Sth(models.Model): .... is_cue = models.BooleanField(default=True) . Querying in shell i got the following: Sth.objects.filter().values_list('is_clue', flat=True) <QuerySet [None, True, None]> . Instead of False i can see there None . In previous versions of Django i used to get only False and True values. What might cause this change? In the database with older and current versions i can see 0 and 1 in the db.

Django: ordering a queryset by dictionary added values
I´m trying to sort a queryset of dictionaries to which I added some calculated values. The process class Inventario(models.Model): codigo_kinemed = models.CharField(max_length=100) existencias = models.IntegerField(help_text="Existencias ", blank=True, null=True) valor_coste = models.IntegerField(help_text="Existencias ", blank=True, null=True) valor_venta = models.IntegerField(help_text="Existencias ", blank=True, null=True) fecha = models.DateField(help_text="Fecha de toma de datos", blank=True, null=True) def __str__(self): return str(self.codigo_kinemed) I get a queyset from that. inventario_diferencia = Inventario.objects.filter(fecha=ultima_fecha_cargada.fecha).values() That returns a queryset of dictionaries. Then I iterate over that queryset and calculate some new fields. for este in inventario_diferencia: este['stock_valor_venta'] = este['existencias'] * este['valor_venta'] I can print that calculated field with no problem in the template. {{ inventario_diferencia.stock_valor_venta }} Ordering I want to sort that queryset by the new stock_valor_ventavalue I added. When I try the usual querset inventario_diferencia.order_by('stock_valor_venta') I get: Cannot resolve keyword 'diferencia_mes' into field. Choices are: codigo_kinemed, existencias, fecha, id, valor_coste, valor_venta Those are the model´s original values, so no option to order by the new value.

django1.11 Custom authentication backend problem --return a unknown URL begin with /user/xxx?
I try to use the custom Authentication Backend in Django 1.11 to build the function (log-in with the user's email rather than the regular log-in with username. And both username and useremail are saved in the same user object in database). With the following code, I can successfully login with username(I input correct username value in HTML form's username blank) and password as a pair. But while I use the email value from HTML form input, It popups the Error as below in the background debug window: error "Not Found: /user/login/ ; "POST /user/login/ HTTP/1.1" 404 " . I am very curious because there is never "user/login" at all in my whole urls.py and users.views.py. how does it come from? Before this inquiry for help, I look up in Django official doc(version 1.11) and other suggestive comments in our stack overflow, but it still has no proper answer with this. Hope your guys save me out and give your ideas. Btw, I also check on 1.11 Django Docs, it said that " Do not forget to test for the is_active attribute of the user in your own backend permission methods.

How to eliminate id path parameter in swagger-ui in DRF-YASG for DRF and DJANGO
I'm using DRF-YASG to document API in Swagger and want to customizing/eliminating some fields shown in parameters I'm running the project with Django 2.1.7, DRF 3.9.2 and DRF-YASG 1.14.0. So, I want to eliminate the ID which is shown in swagger-ui (like a 'string' and 'path'), cause I have it in the body request through Schema, but swagger-ui shows the id (automatically generated field) in parameters.

Django - Execute for loop twice - once without saving and once with saving?
Right now I am trying to confirm a CSV Upload with all the information that is about to be saved in the database. So basically something like: "The following entries are about to be updated/created. Do you want to continue". With my current code I let the user know which entries where updated/created or duplicates. But this happens after it is already saved in the DB. I would like the user to check whether or not the changes he made are correct and only then save it to the database. Here is my views.py (only the part that is relevant) csv_file = request.FILES['file'] csv_file.seek(0) decoded_file = csv_file.read().decode('utf-8').splitlines() row_count = len(decoded_file) #print("d_file: ", decoded_file) reader = csv.reader(decoded_file) liste = list() s = False for row in reader: count += 1 try: datet = datetime.now().date() datum = datet.strftime("%d.%m.%Y") row[7] = datum row[8] = str(request.user) #d = [row[0], row[1], row[2], row[3], row[4]] dataset1 = CSV5.objects.filter(gebaeudebereich=row[0], gebaeudenummer=row[1], ebene=row[2], raum=row[3], dose=row[4])#.values_list("gebaeudebereich", "gebaeudenummer", # "ebene", "raum", "dose") dataset2 = CSV5.objects.filter(switch_ip=row[5], switch_port=row[6]).values_list("switch_ip", "switch_port") ds1 = CSV5.objects.values_list("gebaeudebereich", "gebaeudenummer", "ebene", "raum", "dose") ds2 = CSV5.objects.values_list("switch_ip", "switch_port") #print("ds1: ", ds1) print("dataset1: ", dataset1) print("dataset2: ", dataset2) print("dataset1: ", dataset1.exists()) print("dataset2: ", dataset2.exists()) if (dataset1.exists() and not dataset2.exists()): #instance = get_object_or_404(CSV5, … -

Getting response from django rest endpoint (Search bar)
I'm new to django and need to make search bar in my django-react project. Need to take data from input, send it to django and, as response, receive new queryset. I'm using axios and django-rest framework. From input field within React "Search" component I'm intending to send data via axios like: getQuery = () => { axios.get(`http://localhost:8000/api/SearchPost?q=${this.state.query}`) .then(res => { this.setState({ data: res.data }); input in React: handelChange = (e) => { this.setState({ query: this.search.value}, () => { this.getQuery() }) } render() { return ( <form> <input placeholder="Search..." name="q" ref={input => this.search = input} method="get" onChange={this.handelChange} /> </form> my view.py in django is: class SearchPost(generics.ListCreateAPIView): serializer_class = ModelSerializer def search(request): query = request.GET.get("q") if query: queryset = Model.objects.filter( Q(category_icontains=query)| Q(title_icontains=query)| Q(creator_icontains=query) ).distinct() in urls.py: path('api/SearchPost', views.SearchPost.as_view()), but, as a response I'm reciving nothing. Things I'm asking myself is: 1) Am I sending axios request to the right endpoint? 2) Should I return something in my view.py "SearchPost" class? Any advices are welcome, thank you.
