How to annotate the age of a person based on their date of birth - Django
I am trying to annotate a simple Person object with both the users date of birth and their age to keep the data normalised. I am wishing to later perform some filtering with this annotation so a model property will not work. I have found this blog article (last example) which seems to state what I'm wanting to do is possible, however whenever I actually execute this age is always None I am unsure what is going wrong here, logically it looks sound to me.. models.py class Person(AbstractUser): email = models.EmailField(unique=True) date_of_birth = models.DateTimeField(default=date.today()) views.py class PersonViewSet(viewsets.ModelViewSet): queryset = Person.objects.all() serializer_class = PersonSerializer permission_classes = [permissions.IsAdminUser] def get_queryset(self): queryset = self.queryset.annotate( age = ExpressionWrapper( ExtractDay( ExpressionWrapper( Value(datetime.now()) - F("date_of_birth"), output_field=DateField(), ) ) / 365.25, output_field=IntegerField(), ) ) return queryset -
Deploy Django Project on Hostgator shared hosting
I am currently delving into the world of Django and have aspirations to bring my small project to fruition by deploying it. I have secured a cloud hosting plan with Hostgator for one year, which is a shared hosting option. Although my budget is currently limiting me from utilizing more advanced hosting solutions such as AWS or DigitalOcean. I reached out to Hostgator's customer support team for guidance, but was informed that while they could assist me with deploying the app on the server, they would not be able to provide further support. As a novice, I am still on the hunt for resources that can guide me through the deployment process in a comprehensive manner. I would be immensely grateful for a roadmap that can guide me through this process and any recommendations for online resources that are tailored for beginners such as myself, who are eager to learn.

Dynamic url rendered by Django as an api response, but not by frontend
I'm using Django + Angular, and I have a dynamic url which works for first time when load my product page. I specified as a dynamic url in Django too, so the url look like this "product/home/:productName/:productId". Everything definitely works but as a response when I reload my page, it gets plain API response from Django and the host is changed to the backend one. Why it's happening? I was searching around didn't found anything. url.py path('product/home/<str:handle>/<int:id>', ProductGet) view.py @csrf_exempt def ProductGet(request, handle, id): product = Product.objects.get(id=id) serializer = ProductSerializer(product, many=False) return JsonResponse(serializer.data, safe=False) So, this code works for first time, but then when I reload seems it changes host to Django and I'm getting as a response, my API response. -

Set Extra Fields In Django Generic Many to Many Relationship
Wondering how I could set a generic many to many relationship including additional fields through a post request. Note that I removed some irrelevant fields to make it easier to read. I have only included one of the objects (message) that can have these labels for simplicity. Models class Message(models.Model): text = models.CharField(max_length=250, default='text') labels = GenericRelation(to=Label) class Tag(models.Model): color = serializers.Charfield() class Label(models.Model): tag = models.ForeignKey(to=Tag, on_delete=models.CASCADE) # Generic foreign key object_id = models.PositiveIntegerField() content_type = models.ForeignKey(to=ContentType, on_delete=models.CASCADE) content_object = GenericForeignKey() confidence = models.IntegerField() section = models.IntegerField() class Meta: indexes = [ models.Index(fields=["content_type", "object_id"]), ] Serializers class LabelSerializer(ModelSerializer): class Meta: model = Label fields = ['id', 'confidence', 'level'] class MessageSerializer(serializers.ModelSerializer): labels = serializers.ManyRelatedField( child_relation=LabelSerializer(), required=False) class Meta: model = Message fields = ['id', 'text', 'labels'] The idea would be to have the following post request which would set the relationship between tags and messages, using the custom through table Labels with the additional fields confidence and section set. { 'text': 'Message Text', 'labels': [ { 'tag': 1, 'confidence': 0.9, 'section': 1 }, { 'tag': 2, 'confidence': 0.7, 'section': 1 } ] } -

Django-filters resets after using the UpdateView
I have a Model with a lot of entries, so I'm using django-filters to filter the model, I initially load an empty table and from there I use the filter to view the items. Everything works fine, the page loads initially with no entry, after I filter, django shows the correct items. The Url gets a parameter: /retetabloc/?acordcadru=532(532 is the filter) but when I try to update an entry, the filter resets(the parameter is still in the URL) and the whole db is loaded. I don't quite understand how to pass the filter parameter to the RetetaBlocUpdate, so that after the update is done it returns to the filtered items like in the ListView. views.py class RetetaBlocListview(LoginRequiredMixin, CoreListView): model = RetetaBloc def get_queryset(self, *args, **kwargs): pdb.set_trace() acordcadru = self.request.GET.get("acordcadru") queryset = RetetaBloc.objects.filter(acordcadru=acordcadru) return queryset def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['filter'] = RetetaBlocFilter(self.request.GET, queryset=self.get_queryset()) pdb.set_trace() return context class RetetaBlocUpdate(LoginRequiredMixin, AjaxUpdateView): model = RetetaBloc form_class = RetetaBlocForm Thank you. -

How do I ensure that a Foreignkey field is always referenced in a Django model?
I was thinking of creating an instance of a foreignkey field and referring it every time an instance of a model is created, but I didn't find any solution for this. Usually we need to create a model of foreignkey type and then refer to it from the model, but I want it to automatically create one foreignkey instance from the beginning of and always refer to it. To provide an example let's say we've 2 model fields called User and WeeklySchedule. Everytime an instance of a User is created,another corresponding instance of a WeeklySchedule model is also created that will be referred to by the instance of the User. -

How to make each product have functioning plus minus button on my product page and add its price to the total amount?
I'm working on Ecommerce Website that sells Coffee and my problem is that the only working plus and minus button is the first coffee. The plus and minus buttons on the others are not functioning. Is it about the for statement where I'm wrong? or the structure of the html isn't right. I've copied some of the code on cart.html file to make the product page had the option of adding products to the cart and also has a proceed button to the checkout page. The before structure of the site was you click on the image of a product and directed to the addtocart page then to the checkout page. -
Django test factory post with foreign key
I'm trying to test a view-function with django's RequestFactory's post-method. The view-function should create a new ObjA-instance. ObjA has a foreign key field to an ObjB. My test currently looks like this (names changed for better reading): request = self.factory.post('/create-objA/', data={'objB': objB.id, 'field1': 'dummy'}) request.user = self.user request.POST.is_bound = True create_objA(request) self.assertTrue(ObjA.objects.filter(field1='dummy').exists()) objB does exist, this is tested few lines before in the same test function. However the test in the snippet fails. The reason is that in the following create function form.is_valid() is never true: def create_objA(request): if request.method == 'POST': form = ObjAFormCreate(request.POST) if form.is_valid(): .... So the ObjA is not created. Form is not valid because it has an error in the ObjB reference field: Select a valid choice.
