Spatial join in Django
I am trying to do a spatial join (as explaind here) using PostGIS within Django. The Django spatial lookups do not help. My best clue is to use custom SQL but I would really prefer to keep using a QuerySet query. In plain english my query would be: Select all estates which contains at least one building with type "heavy" Here are my two models: class Building(models.Model): type = models.CharField(max_length=255, null=True, db_index=True) footprint = models.IntegerField(null=True, blank=True) perimeter = models.PolygonField(null=True, spatial_index=True) class Estate(models.Model): city = models.ForeignKey(City, on_delete=models.CASCADE) area = models.IntegerField(null=True, validators=[MinValueValidator(1)]) perimeter = models.PolygonField(null=True, validators=[estate_val.perimeter], spatial_index=True) Is there any way to do something like: estates = Estate.objects.filter(CUSTOM_JOIN_FILTER) -

Is possible add a subquery with anothers relationships in django orm annotate

My actual scenario: Tables class SalePoint(models.Model): location = models.CharField(max_length=200, verbose_name='Local') [...] class Box(models.Model): sale_point = models.ForeignKey( [...] related_name='boxes', [...] ) product = models.ForeignKey( [...] related_name='boxes', [...] ) amount = models.PositiveSmallIntegerField() capacity = models.PositiveSmallIntegerField() class Product(models.Model): name = models.CharField() sku = models.CharField() View SalePointStockViewSet(viewsets.ModelViewSet): def list(self, request): queryset = ( SalePoint.objects.values( 'location', 'boxes__product__name' ).annotate( total_amount=Sum('boxes__amount'), total_capacity=Sum('boxes__capacity'), ) .order_by('location', 'total_amount') ) return Response(queryset) As I had said, my view works fine.

django next url parameter
I am using a custom Login View and a custom login page. What I am struggling with is the next parameter that I want to use so if there is the next parameter in the url then the user is being redirected to the previous page. As you can see in the code below I am using django-crispy-forms and django-axes. The problem is that I am able to successfully redirect users to the homepage but I cannot access any data that is visible for logged-in users (all views are restricted for logged-in users) such as user email, and content. Moreover, when I try to click on any hyperlink Django is automatically redirecting to the login page. When I try to access a page manually, for instance, http://127.0.0.1:8000/articles it redirects me to http://127.0.0.1:8000/accounts/login/?next=/articles/ which gives me Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/accounts/login/?next=/articles/ views.py class UpdatedLoginView(LoginView): form_class = LoginForm template_name = 'user/login.html' redirect_field_name='main/homepage.html' def post(self, request, *args, **kwargs): form = self.form_class(request.POST) if form.is_valid(): if 'next' in request.POST: return redirect(request.POST.get('next')) else: return(redirect('homepage')) else: return render(request, self.redirect_field_name, {'form': form}) class ArticleListView(LoginRequiredMixin, ListView): template_name = 'articles/ArticleListView.html' model = Article paginate_by = 6 queryset = Article.objects.filter(status=1) def get_context_data(self, **kwargs): context = super(ArticleListView, … -
