Django allauth with custom redirect Adapter ignoring "?next" parameter
I am using Django 3.2 and django-allauth 0.44 I have a custom adapter that redirects a user to their profile page upon login - however, I also want to be able to use a ?next=/some/url/ so that a user is redirected to that url if there is a next parameter in the GET arguments. This is my custom Adapter: class MyAccountAdapter(DefaultAccountAdapter): def get_login_redirect_url(self, request): print(f"GET request dict is {request.GET}") return reverse('profile', kwargs={'username': request.user.username}) I suspect that I have to modify my custom adapter, so that it checks for a 'next' GET parameter BEFORE going to the profile page. However, I found to my surprise that it seems: I can't set a breakpoint in the adaptor (it is ignored) If I deliberately introduce an error in the adaptor (e.g. print(request.GET['hello']) ) the code runs fines and redirects to the profile page without throwing an exception How can I use ?next=/some/url with django-allauth whilst also using a custom adaptor? -

how to filter field values based on other field values in Django

Django nested forms
I have trouble figuring out how to create nested forms. I have two models: Poll and Question (foreign key for Poll is inside Question model). I want it to be possible to add several questions for the poll dynamically inside one form. I've already tried making it work with inlineform_factory, but found troubles saving the form. Right now I have overcomplicated code that throws MultiValueDictError after saving the poll for the second time. I thought maybe there is some other way. Here's my code models.py class Question(models.Model): type_choices = ( ('text', 'Текстовый'), ('integer', 'Числовой'), ) type = models.CharField(verbose_name=u'Тип вопроса', choices=type_choices, max_length=70) text = models.CharField(verbose_name=u'Текст вопроса', max_length=255) poll = models.ForeignKey('Poll', on_delete=models.CASCADE, related_name='questions') class Poll(BaseFields): objects = models.Manager() published = PublishedManager() title = models.CharField(verbose_name=u'Заголовок', max_length=70) date_from = models.DateTimeField(u'Дата начала') date_to = models.DateTimeField(u'Дата окончания') status = models.IntegerField(choices=Status.choices, default=0) def status_name(self): return dict(Status.choices).get(self.status) def update_url(self): return reverse('poll_update', args=(self.id, )) forms.py QuestionInlineFormSet = inlineformset_factory(Poll, Question, extra=1, can_delete=False, fields=('type', 'text', 'poll'), widgets={ 'type': w.Select(attrs={'class': 'form-control'}), 'text': w.TextInput(attrs={'class': 'form-control'}), }) class PollForm(CommonForm): class Meta(CommonForm.Meta): model = Poll views.py class Create(BaseCreateView): template_name = 'back/poll/poll.html' page_title = 'Создание опроса' model = Poll form_class = PollForm def form_valid(self, form): result = super(Create, self).form_valid(form) questions_formset = QuestionInlineFormSet(data=form.data, instance=self.object, prefix='questions_formset') if questions_formset.is_valid(): … -

Creating annotation based on subquery with parameters
I have two models in my app, Event and Registration, with the most important fields below: class Event(models.Model): ... capacity = models.IntegerField() ... class Registration(models.Model): timestamp = models.DateTimeField(auto_now_add=True) event = models.ForeignKey(Event, on_delete=models.CASCADE) uses_bus = models.BooleanField(default=False) is_vegan = models.BooleanField(default=False) user = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, default=None) Now, in either a field or in the admin, I am trying to get the number of registrations where the user has marked uses_bus and the number of registrations where the user has marked is_vegan. This could be something like this: class EventAdmin(admin.ModelAdmin): list_display = ('title', 'date', 'nr_registrations', 'nr_bus') inlines = [RegistrationInline] def get_queryset(self, request): queryset = super(EventAdmin, self).get_queryset(request) return queryset.annotate( nr_registrations = Count('registration'), nr_bus = Count('registration', filter=Q(registration__uses_bus=True)), nr_vegan = Count('registration', filter=Q(registration__is_vegan=True)), ) def nr_registrations(self, obj): return obj.nr_registrations def nr_bus(self, obj): return obj.nr_bus def nr_vegan(self, obj): return obj.nr_vegan but this obviously finds the total number of bus registrations, not the number of bus registrations for the ones that can actually attend the event because of the capacity constraints. In SQL I would solve this like this: SELECT SUM(uses_bus) FROM (SELECT CAST(uses_bus AS INTEGER) FROM events_registration WHERE event_id = *event id* ORDER BY id LIMIT *capacity*) AS a but I can't do this, because even if I … -

How to send httponly cookie with axios?
I'm using a django backend, and a CRAO frontend. I saved the jwt refresh token as a httponly cookie: document.cookie = `refresh=${refresh_token}; SameSite=Strict; Path=/api/token/refresh; HttpOnly`; Then to refresh the access token, I'm sending an axios request: const response = await axios.post('/api/token/refresh/', { withCredentials: true }); But, in this case, the originally saved cookies don't get sent by axios. However, on removing the httponly attribute, the cookies do get sent, and everything works fine. -
