UserSignupForm.custom_signup() takes 2 positional arguments but 3 were given
I extended django-allauth's UserSignUpForm for a custom form upon signup but I got an error when I signed up in my local development server.

Google App Engine deployment error 502: Bad Gateway with Django and Gunicorn
I am trying to deploy a Django application on Google App Engine using Gunicorn as the WSGI server. The application works well locally, but when deployed to App Engine, I encounter a 502: Bad Gateway error. I have checked the logs in Google Cloud Console and can't find any relevant errors. Here is my app.yaml configuration file: runtime: python311 entrypoint: gunicorn -b :$PORT --timeout 120 LyAnt.wsgi:application env_variables: DJANGO_SETTINGS_MODULE: "LyAnt.settings" ENV: "PRODUCTION" handlers: - url: /static static_dir: static/ - url: /.* script: auto automatic_scaling: min_idle_instances: 1 max_idle_instances: 2 min_pending_latency: 30ms max_pending_latency: automatic I tried running Gunicorn locally, but it does not work due to the "ModuleNotFoundError: No module named 'fcntl'" error. I understand that Gunicorn is not recommended for Windows environments, so I tested my application locally using Waitress, and it works fine. I expected my application to work on Google App Engine after deployment, but I am encountering a 502 error instead. -

Local gulp not found inside docker container
I am trying to rebuild a past project regarding Django and gulp.js. Gulp is used to build the static assets from Django. I am now dockerizing this project.

DRF Query optimization for nested_serializer with select_related queryset
This is My Model class PropertyBasic(Model): pass class ManagementProperty(Model): propertybasic = models.ForeignKey(PropertyBasic) class PropertyUnit(Model): management_property = models.ForeignKey(ManagementProperty) This is My queryset in view class PropertyUnitListView(ListAPIView): def get_queryset(self): return PropertyUnit.objects.all().select_related('management_property__propertybasic') This is My Serializer class PropertyUnitSerializer(serializers.ModelSerializer): property_basic = PropertyBasicSerializer(source='management_property.propertybasic') ...

Django forms's logic for a form in a base template
I'm trying to figure out how to deal with this situation. I have three views: def view0(request): ... return render(request, 'home.html') def view1(request): ... return render(request, 'about.html') Both view templates extends a template called 'base.html', in which there is a contact form. What I'm wondering is: do I need to write python code in both views to handle all the logic inherent in the form's operation? Or can I create a view whose only job is to handle the logic of this specific form? I tried to create a separate view, assigning it a url to which the 'action' attribute of the form refers: def base_view(request): if request.method == 'POST' contact_form = Form(request.POST) #logic here else: contact_form = Form() context = {'contact_form': contact_form} return render (request, 'base.html', context) def view0(request): ... return render(request, 'home.html') def view1(request): ... return render(request, 'about.html') 'base.html' has the following code for the form: ..... <form action="{% url 'base_view_url' %}" method="post"> {% csrf_token %} {{contact_form}} <input type="submit" value="Invia"> </form> ..... With this code the contact form does not work. -

Database Optimization of a Giveaway Website Using Django
Hello everything is fine? So, the old project that is a "raffle" site has a chronic problem which is the use of up to 1000% of the CPU that is an AMD Ryzen 9 with 16 cores at high peaks of site usage. The total responsible for this enormous use is the database due to its lack of architecture/optimization. The challenge is: Solve this and make the site fast and accessible. For that, I'll use Django and thought of some ways to solve this, among them, here's a possible solution. models.py from the app raffle class Raffle(models.Model): ... amount_of_numbers = models,PositiveInteger(default=100000) The system will define the total number of tickets or the user and with these numbers, in the save method I will create 50-100 .txt files with numbers from 1 to 100000 without repetitions to avoid adding repeated numbers and causing " harmful queries" import fcntl with open('arquivo.txt', 'r') as arquivo: fcntl.flock(arquivo, fcntl.LOCK_EX) ... fcntl.flock(arquivo, fcntl.LOCK_UN) I will use the a lib fcntl to guarantee that only one user has access to that list of numbers (that's why several lists) and avoid having to check repeated numbers in the database and after finishing the process, I will release the … -

Django models and null=True
I am creating an auction website. I have a Django model for Listings. It looks like this: class Listings(models.Model): price = models.FloatField() title = models.CharField(max_length=64) description = models.CharField(max_length=128) imageUrl = models.CharField(max_length=1000, default="") isActive = models.BooleanField(default=True) owner = models.ForeignKey(User, on_delete=models.CASCADE, blank=True, null=True, related_name="user") category = models.ForeignKey(Category, on_delete=models.CASCADE, blank=True, null=True, related_name="category") watchlist = models.ManyToManyField(User, blank=True, null=True, related_name="watchlistListing") def __str__(self): return f"{self.id}: {self.title}, {self.description}, {self.price}, {self.imageUrl}" My problem is that whenever I create a listing and try to access its 'owner' attribute, it returns 'None'. However, I can access the current user perfectly fine by using 'request.user'. I tried removing the null=True and the blank=True parameters from the owner attribute. However this did not work and now whenever I try to access the owner attribute it just says the listing has no owner. type here -

Problems with Django structuring when entering models, views and serializers in folders?
Hello I am learning to program in Django and I have a database of 22 tables, as you can see making all the models in a single class would be very cumbersome and messy to find or make corrections, the same thing happens to me with serializers and views.

I was told that inside each folder create the init.py and integrate there the from of what is created in that folder, but when I start to spread it to the other modules it generates error. Example: Folder Models Models/__init__.py from . import Service Folder Serializers Serializers/__init__.py from . import ServiceSerializer The default models, serializers and views files that are created by default are blank, is that the problem?

why is request.user.is_authenticated printing out false even when user is logged in and rendering template
I am fairly new to Django and I use Django 4.2. I am building a website and I have run into this error. I have created my login function like this def loginUsers(request): context = {} if request.method == 'POST': email = request.POST['email'] upass = request.POST['password'] user = authenticate(request, email=email, password=upass) if user is not None: login(request, user) messages.success(request, 'Login successful') time.sleep(2) return redirect(reverse('index')) else: messages.error(request, 'Invalid user') return redirect(reverse('login')) return render(request, 'auth_pages/login.html', context) But my logout function is not in this contact app views.py. It is in my index app views.py because the logout button in my template is in the navbar. Here it is: def loadIndexPage(request): context = {} print(request.user.is_authenticated) return render(request, 'pages/index.html', context) def logoutUser(request): if request.method == 'POST': logout(request) messages.success(request, 'You are logged out') return redirect(reverse('login')) The problem The problem is that the logout function is not logging out the user, it instead, is creating a csrftokenmiddleware in the browser search bar and when I print the request.user.is_authenticated it prints false.

Where is `.objects` attribute is added to an instance namespace in django's models.Model class?
When in views.py we code something like any_model_name.objects.all() this thing brings us all the objects ever initiated from any_model_name class-model. I've just read all code in models.Model class (the one any model should inherit from) and I just can't find the place where .objects attribute appears there is nothing like that as well as .all() method attribute. My pycharm has the same opinion, it underlines .objects in red and says "Unresolved attribute reference 'objects' for class 'any_model_name'". What the magic prevents me from finding the place in django code where .objects thing appears for the first time? -
