how can i call the instance of a model like we do with request.user for the user model
I'm working on a project where users can create a specific store that will only have their own product, but beyond that, there is a main store whose products from different users are displayed, so I don't know how to do it. filter allowing me to display specific products for each user. I know that with the user we make request.user so how to do with other models? my models file class Shop(models.Model): name= models.CharField(max_length=60, verbose_name='nom') adress= models.CharField(max_length=250, verbose_name='adresse') description=models.TextField(max_length=1000) logo=models.ImageField( blank= True ,null=True ) horaire=models.CharField(max_length=100) user= models.ForeignKey(User, blank= True , null=True ,verbose_name="utilisateur", on_delete=models.CASCADE) date= models.DateTimeField(auto_now_add=True, verbose_name='date de création') data=models.JSONField(null=True,blank=True) def __str__(self) -> str: return str(self.name) my views file def products_list(request): shop=Product.objects.all() products= Product.objects.filter(shop=shop) return render(request , 'shop/product_list', locals()) def home(request): products = [{**vars(p), 'image_url': (p.image and p.image.url) or p.image_url} for p in Product.objects.all().order_by('-name')] special_product= Product.objects.filter(vip =True) productOfday=Product.objects.filter(product_of_day= True ) return render(request, 'shop/home.html', locals()) def create_shop(request): form =CreateShopFrom() error='' if request.method == 'POST': form =CreateShopFrom(request.POST) if form.is_valid: form.save() else: error='identifiants Invalides' return redirect('shop') return render(request, "shop/create_shop.html",locals()) I tried that but without success: def products_list(request): shop=Product.objects.all() products= Product.objects.filter(shop=shop) return render(request , 'shop/product_list', locals()) -

Can't migrate properly a column in a Django database. Anyone know why?
So I'm working on a Django project and I did some changes to my user.py model. I simply added a boolean value to it. When I run the manage.py makemigrations <my app> everything runs smoothly, but when I run manage.py migrate it crashes and displays de following error: django.db.utils.OperationalError: no such column: ""is_admin"" Which I find odd because it is on my model file and I even got to make the manage.py makemigrations <my app> command properly. Does anyone know what's going on? If it makes it more clear I can put the whole error in the comments but I didn't want to add it here since it's very long. I even tried changing the name of my attribute but it doesn't seem to matter. The error still says "is_admin" is not a column. I've tried commenting/deleting the line of code in the model and run the migrations again but it seems kinda stuck on that error. -

Filtering objects by date
My app has an optional date selection. All objects created on that day will be filtered by the selected date. I have a model: class MyModel(models.Model): name = = models.CharField() ... pub_date = models.DateTimeField(auto_now_add=True) Objects will be added every day and there will be a lot of them in the future. I planned to implement filtering with something like this: object = MyModel.objects.filter(pub_date__year=year pub_date__month=month, pub_date__day=day) But it occurred to me that if I make a separate model for the date, link it to the main model and filter by related_name, then the query will be more optimal and faster. class PubDateModel(models.Model): pub_date = models.DateTimeField(auto_now_add=True) class MyModel(models.Model): name = = models.CharField() ... pub_date = models.ForeignKey(PubDateModel, related_name='my_models') If I understand correctly, then my request will look like this: pub_date = get_object_or_404(PubDateModel, pub_date=date) objects = pub_date.my_models.all() Which option will be faster with a very large number of objects in the database? -

Why am I getting 403 for POST with DRF and rest_framework_api_key?
I am getting a 403 response from the server in my new Django app. It is very simple. I don't even have models, I just want to return an audio file, but I want to do it through an API. Because of that, since I am not going to have users, I need an API key, and I found that I can use the Django REST framework and the REST framework API key modules. I have followed the quickstarts and can't seem to get a response. It was working before, but it was authenticating through CSRF, and like I said, it is going to be an API, so I won't have CSRF cookies. Here is the view I am using: @api_view(["POST"]) def tts_view(request): data = request.POST voice_name = data.get("voice_name") text = data.get("text") if not voice_name or not text: return JsonResponse({"error": "Missing voice_name or text"}, status=400) return JsonResponse({"wav": text_to_wav(voice_name, text)}, status=200, safe=False) The settings: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'rest_framework_api_key', 'TTS', ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] REST_FRAMEWORK = { "DEFAULT_PERMISSION_CLASSES": [ "rest_framework_api_key.permissions.HasAPIKey", ] } And the fetch (the API key is just a test, so it doesn't matter): fetch('/create-speech', … -

Django HTTPS on EC2 without a domain name?
I have a Django app working on HTTP with an EC2 instance running Amazon Linux 2. I was hoping to get HTTPS working without a domain name. How would I get a self signed certificate to work with the public IPv4 address assigned to my EC2 instance and then launch the django app on EC2 with HTTPS? Is it even possible? I have tried making a certificate using openssl and running the django app using django-extensions and Werkzeug using python manage.py runserver_plus but the app crashes on ec2 (works fine locally). I have tried a few other python packages with the same results. Any help is appreciated. -

Rest API create class based view using a mixin
I have a view inheriting from APIView and another custom mixin. None of the APIView methods is defined in the view but it is used only for declaring it as view. I need the url from only the mixin. But the mixin's url is never found django.urls.exceptions.NoReverseMatch. I am not sure how exactly to explain the problem therefore, I will provide the code: class TypeAPI(TwoFieldListMixin, APIView): queryset = Type.objects.all() permission_classes = [IsAuthenticated] class TwoFieldListMixin: query_field: str = "id" name_field: str = "name" @action(detail=False, methods=["GET"], url_name="id_code_list") def id_code_list(self, request: Request, *args: None, **kwargs: Any) -> Response: self.query_field = ( request.query_params.get("query_field", None) or self.query_field ) self.name_field = ( request.query_params.get("name_field", None) or self.name_field ) queryset: QuerySet[Any] = self.filter_queryset(self.get_queryset()).values( self.query_field, self.name_field ) serializer: ICListSerializer = ICListSerializer(queryset, many=True) return Response(serializer.data) url.py urlpatterns = [ path("types/", TypeAPI.as_view(), name="types"), ] + router.urls Test that I am writing: def test_pt_detail_api(self)->None: res = self.client.get(f"/api/v1/na/types/id_code_list/") res = self.client.get(url) assert res.status_code == 200 Here is the error: /usr/local/lib/python3.10/site-packages/django/urls/resolvers.py:802: NoReverseMatch django.urls.exceptions.NoReverseMatch: Reverse for 'types-id_code_lis... Or applying some variations give an error: 'request_path': '/api/v1/na/types/id_code_list/', 'exception': 'Resolver404'} Question is how can I achieve creating a simple view which inherits from a mixin and does nothing else. -

Dict in Django TemplateView throws Server Error 500, ListView helps for DetailView
I'm attempting to utilise the dictionary prices to retrieve the stock prices from yahoo finance. And the Django database is where I get my stock tickers. In HTML, I am unable to utilise dict. Please review the code samples I've included below. If the datatype for the variable "prices" is likewise a dict, Django produces a 500 server error. I need to pull stock prices from yahoo finance and show stock tickers from the Django database in HTML. How can I fix it? Please give me some advice on how to show my coins using ListView. In order to assist me with DetailView, which is crucial to my online application. I want to say thank you. Model: class Coin(models.Model): ticker = models.CharField(max_length=10) def __str__(self): return self.ticker View: class BucketView(LoginRequiredMixin, TemplateView): template_name = 'coinbucket/bucket.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) symbols = [symbol.ticker for symbol in Coin.objects.all()] prices = {} for symbol in symbols: ticker = yf.Ticker(symbol) price = ticker.history(period='1d')['Close'][0] prices[symbol] = f'$ {price:.6f}' context["prices"] = prices return context Template: {% for coin in coins %} <div class="col-12 col-md-8 my-2"> <div class="card"> <div class="card-body"> <div class="row"> <div class="col">{{ coin }}</div> <div class="col">{{ prices[coin] }}</div> </div> </div> </div> </div> {% endfor %} … -
Reference Serializer fields from Model in Django Rest Framework
The usual way of creating ModelSerializer in Django Rest Framework is specifying the fields attribute: class MyModelSerializer(serializer.ModelSerializer): class Meta: model = ModelConfig fields = ( 'id', 'uid', 'hashid', 'created_at', 'updated_at', 'added_by', 'updated_by', 'qr_code',) However in bigger projects, refactoring can be easier if the fields can be referenced through their Model, instead of specifying them as a string literal. However I don't know how this could be done in the most OOP way. I have tried using Model._meta.get_field(field) but this also only accepts the field_name, not a reference to the attribute. Something like Model.field.name would be great. Is this somehow possible? -
JavaScript returns value on the first review only, l don't know why
Am having a problem but l nor know what brings it. When I try to loop the Django to for JavaScript to display the Stars, it returns only on the first review and the rest it returns nothing. Now what can't do so that each user who adds a rating it displays it's stars not displaying only the first one? Below it's my HTML and JavaScript below Even l added also an image for results if try to reflesh the page. Html {% for review in reviews %} <p>display of numbers </p> <option value="{{ review.rating }}" id="hours"></option> <div class="staz"> <p id="demo"></p> {% endfor %} JavaScript <script> let hour = document.getElementById('hours').value; let greetings; if (hour == 1){ greetings = "★"; } else if (hour == 2){ greetings = "★★" } else if(hour == 3){ greetings = "★★★" } else if(hour == 4){ greetings = "★★★★" } else if(hour == 5){ greetings = "★★★★★"; } document.getElementById('demo').innerHTML = greetings </script> Results I expected that each review, it returns it's stars. -
