/ in urlpatterns django
I am a beginner in django and don't understand the meaning "/" in urlpatterns. Here is the urlpatterns in my project urls. My first app's name is first. urlpatterns = [ path('admin/', admin.site.urls), path('first', include("first.urls")) ] I found that it didn't work unless I amended it to following: urlpatterns = [ path('admin/', admin.site.urls), path('first/', include("first.urls")) ] I don't understand what the meaning of '/' is. I googled but did not find an answer. Could anyone help me on this? Another question is that the double quotes and single quote could be used either way. But is there any convention or better practice that I can follow to use single or double quote? Thanks a lot. -
How to send dictionary context while returning a redirect function to get context data when calling this function from an api?

django Count on FK with Sum and filters
I have to find the number of participants where the sum of two fields is above a given field. Following models: class Examination(models.Model): total_score = models.FloatField(_('Total score'), blank=False, null=False, default=60) class ExamParticipation(models.Model): examination = models.ForeignKey(Examination, blank=False, null=False, on_delete=models.CASCADE, related_name='examination_participations') total_score = models.DecimalField(_('examination score'), max_digits=3, decimal_places=1, default=0) additional_score = models.DecimalField(_('additional score'), max_digits=3, decimal_places=1, default=0) So for a given Examination I have to count how many participants, where the sum of total_score and additional_core, have more or equal like total_score/2. Is this feasible with a queryset at all or do I have to loop over the results? I tried following query: def count_sufficient_participations(self): qs = self.values('examination_participations').order_by('examination_participations').annotate( ts=Sum(F('examination_participations__total_score') + F('examination_participations__additional_score')) ).annotate(cnt_suff=Count('examination_participations')).filter(ts__gte=30) but does not seem to work and I do not know how to replace 30 with the field total_score from examination. I want to have something like examination.cnt_suff for my template. Any help will be appreciated. -

Update value and keep the key on python dictionary
I have a parking place app where I want to calculate the available days in a week, and the total available hours per day. I have different cities with different timeshifts, some have full time (for example 7:00-20:00) and others have separated time (for example 7:00-14:00 and 16:00-20:00). Here is the loop I tried: def get_available_hours(self): _dict = [] time = 0 query_set = TimeTableCity.objects.filter(city_id=self._city_id) for i in query_set: initial_hour_datetime = datetime.strptime(i.initial_hour, '%H:%M') end_hour_datetime = datetime.strptime(i.end_hour, '%H:%M') time = end_hour_datetime - initial_hour_datetime _dict.append({i.day_table.id: time.seconds / 3600}) time = 0 return _dict And the returned dict at the end is the following: [{4: 5.0}, {4: 4.0}, {5: 5.0}, {5: 4.0}, {1: 5.0}, {1: 4.0}, {2: 5.0}, {2: 4.0}, {3: 5.0}, {3: 4.0}] The key is the day of the week, and the value is the hours for that shift. Is there a way to sum the values for the same key? -
AbstractUser in Django is not authenticating

nginx setup for Django Channels 3 using Daphne and Supervisor

Django social-auth: How to handle Youtube (Google) Auth Error: AuthStateForbidden?
I am using django social-auth to authorize users in Google Analytics and Youtube. Hence one backend in 2 different templates is used.

how to have pagination in a bootstrap modal, such that when it refreshes the modal stays there?
how to have pagination in a modal, such that when it refreshes the modal stays there? Currrently because of the django logic {%%} the page will refresh and it will go to page 2, but the modal would be hidden, I have to open it again. Is there a way to keep the modal there after refresh? Or if better, is there a way to do pagination without using django, through perhaps using javascript instead Django Views.py (this handles the backend for the pagination) paginator = Paginator(album_array, 5) page_number = request.GET.get('page') try: page_obj = paginator.page(page_number) except PageNotAnInteger: page_obj = paginator.page(1) except EmptyPage: page_obj = paginator.page(paginator.num_pages) if page_number is not None: if int(page_number) > 1: page_obj.previous_page_number = int(page_number) - 1 else: page_obj.previous_page_number = False if int(page_number) < paginator.num_pages: page_obj.next_page_number = int(page_number) + 1 else: page_obj.next_page_number = False html: <!-- Pagination --> {% if page_obj.has_other_pages %} <nav aria-label="Page navigation"> <ul class="pagination justify-content-center"> {% if page_obj.has_previous %} <li class="page-item"><a href="?page={{ page_obj.previous_page_number }}"><span class="page-link">Prev</span></a></li> {% else %} <li class="page-item disabled"><span class="page-link">Prev</span></li> {% endif %} {% for i in page_obj.paginator.page_range %} {% if page_obj.number == i %} <li class="page-item active"><span class="page-link">{{ i }}</span></li> {% else %} <li class="page-item"><a href="?page={{ i }}"><span class="page-link">{{ i }}</a></li> {% … -
Is it possible to use the DISTINCT tag on a filtered query?
I am currently working with Django models and I would like to do the following : First, I do a qs = model.objects.all() (where model is the name of my model) Then, I apply some filters on that qs like qs = qs.filter(id_file__startswith=file_id) for instance Finally, I would like to do a raw request (so I can use 'DISTINCT') to get all the distinct places in the "id_place column": for row in qs.raw(f"SELECT file_id, id_place as place FROM {board} group by place"): place = row.place.lower() l_place.append(place) But the problem is that it does the raw request directly in the database, not in the filtered qs. I know it can be done with : places = qs.values("id_place") l_places = set() for row in places: l_places.add(row['id_place']) But I find it not flexible enough for what I would like to do next, and I don't like the fact that I am not using the "DISTINCT" tag that would make this a lot easier and cleaner. Do you have any idea how I could do this ? Thank you in advance! -
