Django Next.js handling responses when signing up
I am building my first Django + Next.js app and I want to display an alert when the user sign up if the username or the email already exists. Currently, if the user chooses an username/email that already exists there is a 400 error (what I want), otherwise everything is working fine. When I try it on postman, I get the explicit problem (username already exists or email already exists). But I didn't manage to achieve that on my frontend, even in the console, I don't see any message. RegisterView : class RegisterView(APIView): permission_classes = (permissions.AllowAny, ) def post(self, request): try: data = request.data email = data['email'] username = data['username'] password = data['password'] re_password = data['re_password'] if password == re_password: if len(password) >= 8: if not User.objects.filter(username=username).exists(): if not User.objects.filter(email=email).exists(): user = User.objects.create_user( email=email, username=username, password=password, ) user.save() if User.objects.filter(username=username).exists(): return Response( {'message': 'Account created successfully'}, status=status.HTTP_201_CREATED) else: return Response( {'message': 'Something went wrong when trying to create account'}, status=status.HTTP_500_INTERNAL_SERVER_ERROR) else: return Response( {'message': 'Account with this email already exists'}, status=status.HTTP_400_BAD_REQUEST,) else: return Response( {'message': 'Username already exists'}, status=status.HTTP_400_BAD_REQUEST) else: return Response( {'message': 'Password must be at least 8 characters in length'}, status=status.HTTP_400_BAD_REQUEST) else: return Response( {'message': 'Passwords do not … -
Can't see images in Django Rest Framework response

So i'd want to see all the photos connected to an Entity, when i see entity/id/detailview. I tried adding the field entity_photos but in the response i get everyhing but entity_photos. Like its hidden. Do you know how can i show the photos that have entity_id == self.kwargs['pk']? -
django: unable to save new user
I'm trying to build a view that shows a form for creating a new user. Next are the template I'm using and the code attempts at views.py and forms.py. user_form.html <form action="{% url 'app:register' %}" method="post"> {% csrf_token %} {{form.as_p}} <input type="submit" value="Register"> </form> First attempt: views.py class NewUser(generic.CreateView): model = User fields = ['username','email','password'] template_name = 'app/user_form.html' success_url = reverse_lazy('register') This one didn't return errors, but was unable to save the new user data. Second try involved creating a form for the occasion: forms.py class NewUserForm(forms.Form): username = forms.CharField(max_length=100) email = forms.EmailField() password = forms.PasswordInput() views.py class NewUser(generic.CreateView): model = User fields = ['username','email','password'] template_name = 'app/user_form.html' success_url = reverse_lazy('register') This one returned an error: TypeError at /newuser/ BaseForm.__init__() got an unexpected keyword argument 'instance' Third: forms.py class NewUserForm(forms.ModelForm): class Meta: model = User fields = ['username','email','password'] views.py class NewUserView(generic.CreateView): model = User form_class = NewUserForm template_name = 'app/user_form.html' success_url = reverse_lazy('cadastro') Can't save a new User instance either. I've also noticed that the model = User line in this last try can be removed. I'm using the User.objects.all() query in the terminal and the admin page to check for new users. What am I not doing? -

Exclude field from Django validation in admin form
I am working on project with a lot of legacy code base. I have a custom model field for price that goes like this class PriceField(PositiveIntegerField): def get_prep_value(self, value: float) -> Optional[int]: return int(value * 100) if value else self.default def from_db_value(self, value: int, expression, connection) -> Optional[float]: return value / 100 if value else value class Expertise(models.Model): price = PriceField(blank=True, default=0, help_text='Price per min.') ... Prices are stored in db multiplied by 100, e.g. 9.90 is stored as 990, and values are obtained from db in human readable way (990 as 9.90). Now I am facing a problem with default PositiveIntegerField Django admin form validation for that field. Because this value represented as float every time I click "Save" I get a PositiveIntegerField's ValidationError. Is there any way to exclude this field from admin form validation or to send this field value multiplied by 100? -
Unable to upload files/images to cloud storage (GCP) with Django
I am trying to upload files & images to the GCP bucket which I created a while ago. I am using Django rest-framework as the backend. I came across this library called [django storages][1].

Structuring multi-apps Django project to minimize import dependancies
I am trying to reorganize my project in order to minimize dependancies and get rid of potential circular imports, especially when doing the first migrations on an empty database to create the apps from scratch. To minimize those dependancies, I currently have 4 apps: puzzles (contains all info about puzzles) users (all info about users) games (everything that relates to a user performing a puzzle) puzzle_explorer (generates new puzzles) I'm however interested (for instance) by the number of users that completed a specific puzzle, so I first defined a property nb_users_who_completed in the puzzles.Puzzle model ... which leads to two-directional dependancies and potential circular imports Because in reality, there are of course a lot more models, and lot more cross-app properties, quick and dirty won't be sustainable. I've first thought about "extending" the different models (plus managers) in puzzles through Mixins: #in games: class Puzzle_Games_Mixin(object): @property: def nb_users_who_completed(self): return pass def custom_method1(self): pass # in puzzles: from games.mixins import Puzzle_Games_Mixin class Puzzle(Puzzle_Games_Mixin, models.Model) That makes the modularity more clear, but does not really help in term of solving circular imports The second strategy I thought of, is to extend in games the Puzzle model with the extra cross-application functionalities (as … -

Django server not initializing with Docker?
I'm new to Docker, and I'm not being able to make it work. I'm on Windows. I cloned the repository https://github.com/18F/docker-compose-django-react, went to VSCode and built the containers with the "Remote - Containers" extension. When I try to access http://localhost:8000/, I get the message "localhost didn’t send any data.", although the React http://localhost:3000/ loads correctly. If I open the terminal from inside the Container, go to the correct folder and run python manage.py runserver, I can access it normally. So it seems that the server isn't being initialized on the Dockerfile/docker-compose. I'm also having this trouble on a setup I'm trying to make from some blog posts. How can I fix/debug this? -
Django implementation of if-else statement
I want to implement a django payment system using a payment platform named mpesa. I also want to print "hello world" on the console every time the page loads or when the request.POST.get('action') == 'post' is not triggered when the function is accessed. I have my code below. def pay_online(request): response_data = {} current_user = request.user queryset = Individual.objects.filter(user = request.user.id) if queryset.exists(): queryset = Individual.objects.get(user = request.user.id) else: queryset = Business.objects.get(user = request.user.id) if request.POST.get('action') == 'post': print("hello world 1") MpesaNo = request.POST.get('mpesaNumber') response_data['message'] = "Check your phone for ussd prompt to complete the payment." access_token = MpesaAccessToken.validated_mpesa_access_token api_url = "https://sandbox.safaricom.co.ke/mpesa/stkpush/v1/processrequest" headers = {"Authorization": "Bearer %s" % access_token} request = { "BusinessShortCode": LipanaPpassword.Business_short_code, "Password": LipanaPpassword.decode_password, "Timestamp": LipanaPpassword.lipa_time, "TransactionType": "CustomerBuyGoodsOnline", "Amount": queryset.ccTotal, "PartyA": Number, "PartyB": LipanaPpassword.Business_short_code, "PhoneNumber": Number, "CallBackURL": "https://sandbox.com", "AccountReference": "Trial", "TransactionDesc": "Trial payments" } response = requests.post(api_url, json=request, headers=headers) return JsonResponse(response_data) else: print("hello world") context = {'queryset':queryset} template = 'payments_page.html' return render(request, template, context) My main question is why this is not displaying "hello world" on the console when request.POST.get('action') == 'post' is not triggered. -
