How to return Queryset using Annotate and SUM in Django ORM?
I'm setting a new ViewSet using Django Rest Framework. And I want to return values from the database using Annotate and Sum with Django ORM (Or raw query). Trade.objects.value('company_id', 'fund_id', 'buy_sell').annotate(quantity=Sum('quantity')) How to be able to return queryset using them? This is just an variation of Trade.objects.all() I also tried using raw query: Trade.objects.raw("""SELECT `id`, `fund_id`, `company_id`, `buy_sell`, SUM(`quantity`) AS `quantity` FROM `operations_trade` GROUP BY `fund_id`, `company_id`, `buy_sell`""") No success. This is my serializer: class TradeSerializer(serializers.ModelSerializer): class Meta: model = Trade fields = '__all__' The Model: class Trade(models.Model): company = models.ForeignKey('Company', on_delete=models.CASCADE) is_directional = models.BooleanField(default=True) fund = models.ForeignKey('Fund', on_delete=models.CASCADE) broker = models.ForeignKey('Broker', on_delete=models.CASCADE) currency = models.ForeignKey('Currency', on_delete=models.CASCADE) buy_sell = models.CharField(max_length=1) quantity = models.IntegerField() unity_price = models.FloatField() commission = models.FloatField() foreign_exchange = models.FloatField() date = models.DateField() settlement = models.DateField() And my View: class TradeViewSet(viewsets.ModelViewSet): serializer_class = TradeSerializer queryset = Trade.objects.all() def get_queryset(self): queryset = Trade.objects.all() filtrated = self.request.query_params.get('filtrated', None) if filtrated is not None: queryset = Trade.objects.values('company_id', 'fund_id', 'buy_sell').annotate(quantity=Sum('quantity')).order_by('fund_id') # queryset = Trade.objects.raw("SELECT `id`, `fund_id`, `company_id`, `buy_sell`, SUM(`quantity`) AS `quantity` FROM `operations_trade` GROUP BY `fund_id`, `company_id`, `buy_sell`") return queryset I expect the output of queryset as an dict/object to use on the client side.

Different URL request than expected
I have a question about ajax url for comment delete problem is this Expected URL: delete_comment_ajax/223 Executed URL: /todo/31/delete_comment_ajax/223 It's probably because I originally went to the detail page and then sent the request. If you know how to fix it, please let me know. $(".comment_delete_button").click(function(e) { e.preventDefault(); var id = $(this).attr("id"); alert('삭제 id : ' + id); $.ajax({ type: "POST", url: 'delete_comment_ajax/' + id, data: { csrfmiddlewaretoken: '{{ csrf_token }}' }, success: function(result) { $("#comment_table_" + id).remove(); alert('comment 삭제 complete '); } }); }); -
LoginForm produces unknown validation error in Django
I have created a Login and Register Model form. Register form is working fine but when I submit Login form it shows a validation error "User with this Email already exists" which I did not define.

Django SearchRank annotation not being assigned, bug in production but not dev
My Django application (Apache/WSGI with Postgres backend) is running into an error in production which I can't reproduce in dev or by using the Django shell on the production machine. How can I debug this? The application has a Story model class Story(models.Model): title = models.CharField(max_length=400) content = models.TextField(blank=True) quality = models.FloatField(default=0) search = SearchVectorField(null=True) with a signal to populate search on save: @receiver(post_save, sender=Story) def update_search_vector(sender, instance, **kwargs): Story.objects.filter(pk=instance.pk).update(search=SearchVector('title', 'content')) When a user searches, I want to return relevant and high-quality results. I assign score as the harmonic mean of these two values: query = SearchQuery(form.cleaned_data['query']) stories = stories.annotate( rank=SearchRank(F('search'), query), score=F('rank') * F('quality') / (F('rank') + F('quality')) ).filter(rank__gte=SEARCH_RANK_CUTOFF).order_by('-score') This works fine in dev and on the Django shell in production. But when executed via the running app, the following error is raised: django.core.exceptions.FieldError: Cannot resolve keyword 'rank' into field. I'm having trouble figuring out how to debug this. Could it be some kind of erroneous queryset caching? -

DRF and Token authentication with safe-deleted users?
I'm using a Django package named django-safedelete that allows to delete users without removing them from the database. Basically, it adds a delete attribute to the model, and the default queries like User.objects.all() won't return the deleted models. This works as expected, except in one case. I'm using Token Authentication for my users with Django Rest Framework 3.9, and in my DRF views, I'm using the built-in permission IsAuthenticated. Here is the code : class IsAuthenticated(BasePermission): """ Allows access only to authenticated users. """ def has_permission(self, request, view): return bool(request.user and request.user.is_authenticated) The problem When a user is soft deleted, he's still able to authenticate using its token. I'm expecting the user to have a 401 Unauthorized error when he's soft deleted. What's wrong? -

Invalid form when uploading file in Django

Django (CSRF token missing or incorrect) suppress logging
In our webapplication it's pretty common that users accidentally open the login page in multiple tabs and trigger the "CSRF token missing or incorrect" error in Django. I would like to suppress this specific message in our logging, because it generates a lot of noise and the issue isn't really fixable. On the other hand, any other issue in the login process should be logged, so I would not want to exclude a whole Django app or class from logging. Do you have any suggestions on how to suppress this specific common error message?
