Django: I want to track from which url a request was made?
in the TestQuestionList class, the get function must receive an id to return id, I thought that I could do this with the help of request.get_full_path()example on the bottom class TestQuestionList(APIView): def get(self, request): obj = Test.objects.get(id = request.get_full_path()) romms = TestQuestionBlok.objects.filter(id__in=obj.questions) serializer = TestQuestionSerializers(romms, many=True) return Response(serializer.data) but request.get_full_path() instead of /tests/api/ (where the request was made from) returned /api/question/ why? This is part of the code from where the request was made useEffect(() => { axios({ method: 'GET', url: 'http://127.0.0.1:8000/api/questions/', }).then(response => { setAllQuestions(response.data) }) }, []) Thanks in advance for your replies -
Django modifying login view has no effect
Long story short: No matter what I do with the login view, it won't change the behavior of the login form, I can delete my views altogether (and urls) and it still works, so it must be picking it up from somewhere else. From where and how do I change that? Long version: I was following a tutorial to implement login, logout and registration with django built in features, it is actually working fine but when I was trying to modify the login view I just realized that no matter what I tried to do in the view, it wouldn't change the behaviour (I was trying to redirect to a different page if the user was already logged, for instance). I started playing around to see what I could change and how it would reflect, even adding prints, but nothing happened, until I decided to try replacing all the code inside the login view function with pass, AND IT STILL WORKED! It happens the same with the logout view, but it doesn't with the register view. I don't understand what's going on. I tried to find something online, but I couldn't find anything related to this exact issue. This is … -
Accept URL as parameter in path (special characters)
I have a view and a path where I'd like to accept a str parameter and pass it to my make_request view. The problem I'm having is the strings I'd like to accept are URLs.

Django ORM filtering using expression against multiple fields
I am trying to use Django ORM filter to retrieve Announcement records with announcement_dates that are later than the current date - "expire_in_days" field - i.e., retrieve announcements that have not yet expired. Here is the SQL representation of what I am trying to do with ORM: select * from announcement where message_date > current_date - expire_in_days; I should be able to retrieve all records and filter them externally, but I am trying to learn how to do this with Django. Here is my model class Announcement(models.Model): message = models.TextField("announcement message") message_date = models.DateField("Announcement date") expire_in_days = models.PositiveIntegerField("Number of days before announcement expires") def __str__(self) -> str: return '(message: %s, message_date: %s, expire_in_days: %s)' % (self.message, self.message_date, self.expire_in_days) Here is what I tried but it did not work: In [1]: from events.models import Announcement In [2]: from datetime import date, timedelta In [3]: from django.db.models import F In [4]: date.today() Out[4]: datetime.date(2022, 5, 29) In [5]: date.today() - timedelta(days=2) Out[5]: datetime.date(2022, 5, 27) In [6]: Announcement.objects.all() Out[6]: <QuerySet [<Announcement: (message: There is a surprise coming up!, message_date: 2022-05-27, expire_in_days: 1)>]>" In [7]: Announcement.objects.filter(message_date__gt = (date.today() - timedelta(days = F('expire_in_days')))) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) Input In [7], in … -

django_filters filter_overrides not applying to CharFields with choices
I have declared a django_filters.FilterSet with a Meta class where I would like to use filter_overrides in order to customise some of the filters. I am using code very similar to the example in the official documentation: class AccommodationFilter(django_filters.FilterSet): class Meta: model = AccommodationOffer fields = ['numberOfPeople', 'petsAllowed', 'typeOfResidence', 'startDateAccommodation' ] filter_overrides = { models.BooleanField: { 'filter_class': django_filters.BooleanFilter, 'extra': lambda f: { 'widget': forms.CheckboxInput(attrs={'class':'form-control', 'value' : 'true'}), }, }, models.CharField: { 'filter_class': django_filters.ChoiceFilter, 'extra': lambda f: { 'widget': forms.Select(attrs={'class':'form-control'}), }, }, } The BooleanFields are showing up as expected, however no matter what I try, the CharFields (which have choices set) do not render with the class="form-control" attribute. -

Django CBV inheritance not working as expected
I use these two classes to get the context data and check permissions respectively: class RestaurantView(View): def get_context_data(self): ctx = {'restaurant': get_object_or_404(Restaurant, slug=self.kwargs['slug'])} return ctx class ManageRestaurantMixin(LoginRequiredMixin, UserPassesTestMixin, RestaurantView): def test_func(self): ctx = super().get_context_data() return ctx['restaurant'].owner == self.request.user Now the first one is working, so when i don't need permission i get the expected behavior, for example with this DetailView: class Info(RestaurantView, DetailView): model = Restaurant context_object_name = 'restaurant' template_name = 'restaurant/info.html' But then if inherit from ManageRestaurantMixin the permissions are checked as expected, but the context object is not working and the template displays an empty form: class EditInfo(ManageRestaurantMixin, UpdateView): model = Restaurant context_object_name = 'restaurant' template_name = 'restaurant/edit_info.html' fields = ['name', 'address', 'logo'] success_url = '/account/myrestaurants' I get that the context gets overwritten, but i don't get how. How can i solve this? Is there a better way to handle this kind of situations? -

Waypoints infinite for loading chat messages when scrolled to top of scrollable element
I'm trying to load chat messages when the user scrolls to the top of the div (the div is scrollable, so the context isn't the window, it's the div). Also when the page loads the div is automatically scrolled to the bottom. I'm doing this in django and when running this code the waypoint is triggered when the user is scrolled to the bottom, but the div that should be triggering it (id=trigger-load) is above the viewport. I've tried adding a set timeout for the initialization of infinite_chat but that also didn't work. This is the code: class ChatDetail(LoginRequiredMixin, generic.ListView): login_url = reverse_lazy('login') model = Message paginate_by = 20 context_object_name = 'messages' template_name = 'index.html' Html: ``` <div class="overflow-y-scroll px-5 pt-5 flex-1 infinite-container-chat" id="chat-content"> {% if page_obj.has_next %} {% include 'partials/common/loader.html' %} {% endif %} <div class="" id="trigger-load"></div> {% include 'partials/friend_hidden_message.html' %} {% include 'partials/user_hidden_message.html' %} {% for message in messages reversed %} {% if forloop.first %} <div class="infinite-item"> {% if user.id == message.user.id %} {% include 'partials/user_message.html' %} {% else %} {% include 'partials/friend_message.html' %} {% endif %} </div> {% else %} <div class="infinite-item"> {% if user.id == message.user.id %} {% include 'partials/user_message.html' %} {% else %} {% include … -

How to put up new content some part of a div is pressed
