Summing up multiple class Def function to get total amount in Django models
I've gone through questions relating to my question, but none is pointing to what I've in mind. I've different class model, with def functions. I can achieve the total amount for each model, but what I want to achieve is, after getting the total amount for each model, how can I sum to models together, to get my total amount for all the models.

Using fetch() to dynamically update objects rendered on HTML page?
I am developing a dictionary app using Django. I have a bookmarks page that lists bookmarked definitions. Every bookmarked definition has a button to remove the bookmark. My problem is that when I remove the bookmark from a bookmarked definition it does not go away from the bookmarks page until I refresh the page. In bookmark.js, am trying to call fetch() after I remove the bookmark from the definition to "reload" or "update" the content of the page dynamically: function bookmark(event) { // Get definition id. let id = event.target.id.split("-")[1]; // Add/remove bookmark to definition. $.get("/bookmarks/bookmark/" + id, function (data) { if (data.added) { alert('Definition added to your bookmarks.') event.target.innerHTML = 'Remove definition from your Bookmark'; } else if (data.removed) { alert('Definition removed from your bookmarks.') event.target.innerHTML = 'Add definition to your Bookmarks'; } }); // Get updated list of bookmarks. fetch('/bookmarks/') // <---------------- PROBLEM } $(window).on("load", () => { $(".bookmark-btn").each(function (index) { $(this).on("click", bookmark); }); }); This is my views.py: # URL: /bookmarks/ class BookmarksView(generic.ListView): """Lists bookmarked definitions.""" model = Definition template_name = "bookmarks/bookmarks.html" def get_context_data(self, **kwargs): language = get_language() bookmarks = self.model.objects.filter(language=language, is_bookmarked=True) context = super().get_context_data(**kwargs) context["bookmarks"] = bookmarks.order_by("-publication_date") return context # URL: /bookmarks/bookmark/definition_id def bookmark(request, definition_id): """Toggles … -
Running custom Django command from Apache
Objective I'm trying to deploy my application in Django to Apache on a raspberryPi to be able to access my website from another PC connected to the same wifi. Setup Apache As for now I have the following Apache default config file /etc/apache2/sites-available/000-default.conf <VirtualHost *:443> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host.

Django display a png created with a view
I am currently working on a project on which I want to build a website where you can enter any URL. With clicking on a button you should get a screenshot of this requested website. Furthermore, there is another button that modulates this png into an RGB-image.

Django-filters how to create dynamically filterset_fields
I wrote a viewset, which depends on the endpoint: ALLOWED_ENTITIES = { 'persons': [Person, PersonSerializer, '__all__'], 'locations': [Location, LocationSerializer, ('country', 'city', 'street')], 'institutes': [Institute, InstituteSerializer, ('number', 'name_short', 'mail_domain')], } class EntityViewSet(viewsets.ModelViewSet): filter_backends = [DjangoFilterBackend] filterset_fields = '__all__' #should be ALLOWED_ENTITIES[self.kwargs['entity_name']][2] def get_queryset(self): model = ALLOWED_ENTITIES[self.kwargs['entity_name']][0] return model.objects.all() def get_serializer_class(self): serializer = ALLOWED_ENTITIES[self.kwargs['entity_name']][1] return serializer urls.py: urlpatterns = [ path('', RedirectView.as_view(url=reverse_lazy('aim:api-root'))), url(r'^api/(?P<entity_name>\w+)', EntityListView.as_view({'get': 'list'})), url(r'^/admin/', admin.site.urls), ] and it works as expected, when i go to /api/persons it shows me viewset with Person Model and PersonSerializer. But the problem, that i dont know how to define filterset_fields = ALLOWED_ENTITIES[self.kwargs['entity_name']][2] and i can not use filterset_fields = '__all__' because i get the following error: Unsupported lookup 'icontains' for field 'aim.Department.parent'. where 'aim.Department.parent' is ForeignKey. Perhaps someone knows how to dynamically define filterset_fields. Thank you in advance. -
DJANGO POST GET not working after i18n translation
I have multiple POST requests from my template for example: $.ajax({ url: '/apply_payment', type: 'POST', data: { basket: JSON.stringify(basket), key: $('#key_input').val(), csrfmiddlewaretoken: CSRF_TOKEN }, dataType: 'json', success: function (data) { $("#key_input").val(""); }, ... I read in the basket data in a view.py like this: basket = request.POST.get('basket', '') In the urls.py I have these urls in the form of: path('apply_payment', entrance_api.apply_payment, name='apply_payment'), Now lately I added i18n_patterns into the URLs, and translated all of my pages, however the AJAX calls stopped working. I guess it is becase the URLs are dynamically changing between selected languages, but I might be wrong. For example the shows basket variable is always None in the view now. How can I fix this? -
Django - create new Objects when new user is registered
I am working on a bet app / guessing app. The user can bet on all NFL games and guess the correct result. So I made 4 Models (2 relevant for my current problem): class Customer(models.Model): name = models.ForeignKey(User,on_delete=models.CASCADE) points = models.IntegerField(null=True, default=0) class Tipp(models.Model): # model for one gameday (17 gamedays at all) user = models.ForeignKey(Customer, on_delete=models.CASCADE, null=True, blank=True) week = models.ForeignKey(Game, on_delete=models.CASCADE, null=True, blank=True) result_hometeam1 = models.IntegerField(null=True, blank=True) result_guestteam1 = models.IntegerField(null=True, blank=True) ... So there are 16 games every week the user can bet. For this I created a form and implement in the template: class Tipp_form(ModelForm): class Meta: model = Tipp fields = '__all__' # views.py def week(request, pk): game = Tipp.objects.get(id=pk) form = Tipp_form(initial={'user':request.user, 'week':game}, instance=game) if request.method == 'POST': form = Tipp_form(request.POST, instance=game) if form.is_valid(): form.save() return render(request, 'main/week.html', { 'game': game, 'form': form, }) everything is working perfectly but now if a new user register I dont want to create 17 new weeks with 16 games every gameday! Is there a way to say: if a new user is logged in, create 17 new objects in Tipp and set user = new User? -
django filters.py @property def qs user
I am trying to filter the associated_portfolios fields object to only those created by the user. Which worked before I tried to add pagination (which is working if I remove the current filter I have for associated_portfolios) I believe what I need to do is remove: def associated_portfolios this is because it seems request is not past with the new setup. Instead, I should use this method https://django-filter.readthedocs.io/en/stable/guide/usage.html#filtering-the-primary-qs filters.py current; not working after adding pagination def associated_portfolios(request): associated_portfolios = Portfolio.objects.filter(user=request.user) return associated_portfolios.all() class TradeFilter(django_filters.FilterSet): associated_portfolios = django_filters.ModelMultipleChoiceFilter(queryset=associated_portfolios) date_range = django_filters.DateFromToRangeFilter(label='Date Range', field_name='last_entry', widget=RangeWidget(attrs={'type': 'date'})) class Meta: model = Trade fields = ['status', 'type', 'asset', 'symbol', 'broker', 'patterns', 'associated_portfolios'] filters.py possible solution based on documentation class TradeFilter(django_filters.FilterSet): date_range = django_filters.DateFromToRangeFilter(label='Date Range', field_name='last_entry', widget=RangeWidget(attrs={'type': 'date'})) class Meta: model = Trade fields = ['status', 'type', 'asset', 'symbol', 'broker', 'patterns', 'associated_portfolios'] @property def qs(self): parent = super().qs user = getattr(self.request, 'user', None) return parent.filter(user=user) The problem is the is no error message but the objects not created by the user are still showing.

Django query is very slow - filter and order by DATE, multiple additional filters
In my Django app, a UserProfile subscribes to many Artists (M2M) through a Subscription table (OneToOne with each). An Artist has an M2M relationship with Releases. I'm trying to display the relevant releases to to users, these should be: released within the last month (release date range: [month_ago, now]) from an artist the user follows have a type field that is in the user's wanted_type They should be distinct, and ordered by their release date. I have an index on Release.release_date (notice: DateField, not DateTimeField). This query is taking quite a long time. Often more than 10 seconds. Here's how I'm doing it: # notice: some model names are actually different in the database, they do match in actual code # selectors.py def get_releases_for_profile(profile: UserProfile): profile_wanted_types = profile.get_release_types() profile_art_ids = profile.subscription_set.all().values_list("artist__id") releases = Release.objects.filter( artist__id__in=profile_art_ids, type__in=profile_wanted_types ) return releases # views.py day_offset = 30 delta = timedelta(days=day_offset) past_delta = now - delta profile_rgs = selectors.get_releases_for_profile(profile=current_profile) past_month_releases = ( profile_rgs.filter(release_date__range=[past_delta, now]) .order_by("-release_date") .distinct() .prefetch_related("artist_set") ) context["past_month_releases_count"] = past_month_releases.count() context["past_month_releases"] = past_month_releases[:20] If I dump PostgreSQL's cache with sync && sudo purge to avoid calling it from the cache, this takes anywhere from 10-14 seconds.
