Limit on Number of cart-products
I'd like to set a limit on the number of products that can be added on a cart. --Case scenario: Assuming delivery-resource scarcity, I don't want users to add more than 5 products at a time. (The quantity of same product can, however, be raised) cart-app/cart.py def add(self, product, quantity=1, override_quantity=False): product_id = str(product.id) if product_id not in self.cart: self.cart[product_id] = {'quantity': 0, 'price': str(product.price)} if override_quantity: self.cart[product_id]['quantity'] = quantity else: self.cart[product_id]['quantity'] += quantity self.save() def __iter__(self): products = Product.objects.filter(id__in=product_ids) cart = self.cart.copy() for product in products: cart[str(product.id)]['product'] = product for item in cart.values(): item['price'] = Decimal(item['price']) item['total_price'] = item['price'] * item['quantity'] yield item I've tried slicing my queries but this doesn't work. Any ideas? -
How to know which group a user belongs to
I am developing an application that allows me to control the users that belong to a certain group, but I find a problem that I don't know how to do correctly, I currently have two groups that are day and night, but I have a problem, and that is that those groups They are validated to know which one they belong to and thus show only information from that group, but if I wanted to add more groups than I have, is there a way to know which group a user belongs to and so on to be able to validate the information that I show in templates, this is my model: class User(AbstractUser): def get_full_name(self): return f'{self.first_name} {self.last_name}' @receiver(post_save, sender=User) def group_user(sender, instance, *args, **kwargs): if instance.groups: if instance.groups == 'diurno': group = Group.objects.get(name='diurno') instance.groups.clear() instance.groups.add(group) else: group = Group.objects.get(name='nocturno') instance.groups.clear() instance.groups.add(group) This is my view: class CarListView(LoginRequiredMixin, ListView): login_url = 'users:login' template_name = 'index.html' paginate_by = 6 def get_queryset(self): group = self.request.user.groups.filter( name='diurno').exists() if group: return Car.objects.annotate(Count('partner')).order_by('-pk') else: user = User.objects.filter(pk=self.request.user.pk).first() return Car.objects.filter(user=user) -
Pycharm CE not hitting breakpoints in my Django project
I have my project properly configured to run manage.py in the right place, with the right settings. I also have debug breakpoints set in a method that I know with certainty is being executed. The breakpoints are not disabled or conditional: When I hit the "Run in debug mode" button, using the above run configuration (I'm sure it's the same one because it's the only one I've configured for this project), this is the console output I get: pydev debugger: process 38083 is connecting Connected to pydev debugger (build 192.5728.105) Watching for file changes with StatReloader Performing system checks...

However, when I use a REST client to trigger the above method, the one with breakpoints in it, the breakpoints do not trigger and the debugger doesn't start.

Django model store information for each user
I am building a competition website where challenges will be released weekly. For each user I want to track if they have completed a challenge but cannot see how this would be done. Currently the challenges are stored as a model and am using the ListView and DetailView to display them. from django.db import models from django.contrib.auth.models import User STATUS = ( (0, 'Draft'), (1, 'Publish'), ) class Challenge(models.Model): title = models.CharField(max_length=200, unique=True) slug = models.SlugField(max_length=200, unique=True) release_date = models.DateTimeField() preamble = models.TextField() ciphertext = models.TextField() plaintext = models.TextField() status = models.IntegerField(choices=STATUS, default=0) class Meta: ordering = ['-release_date'] def __str__(self): return self.title Thank you in advance to anyone who helps me with this.

No Reverse Match in login view Django, html template parsing error
I have an issue with my django application. My base.html template can be parsed in certain views but not in all of them and returns an error code I do not have much experience with django but it seems to be that it can parse the template when the views aren't too far away from each other.

My Django & React program crushes with Forbidden 403 Error
I am creating a project following the YouTube tutorial at this link: https://youtu.be/JD-age0BPVo?t=133 I recently did the 6th and 7th video, but accidentally, I started from the 7th and got back to the 6th video.

Django template custom filter does not change size of button
I have a Django template variable and custom filter inside a button stylized with bootstrap 4. <button type="submit" class="btn btn-outline-dark text-left mb-2" disabled> {{ my_variable | my_filter}} </button> If my_filterincreases the length of my_variable, I find that the size of the button is not automatically extended as I assume that its size is processed by Django before the filter is applied.

Run a subprocess along with Django runserver
I am a novice at Django. I have a simple python script which I execute via a custom command using manage.py, which in turn sets up a subprocess that keeps running. I am using the subprocess to publish message to all channels connected to my server. Right now, the way my code works is that my server runs in one terminal tab while I use a second terminal to run my custom command. My question is, what do I need to do so that whenever I start my server, the subprocess automatically begins in background and keeps on running until server is stopped? I have tried adding the subprocess to ready method of my apps.py, but that does not work. I also tried using channels' background tasks, but that again require executing another command. My custom command handler file from django.core.management.base import BaseCommand from asgiref.sync import async_to_sync import subprocess from channels.layers import get_channel_layer channel_layer = get_channel_layer() class Command(BaseCommand): def handle(self, *args, **kwargs): with subprocess.Popen(['python3', '-u','script.py'],stdout=subprocess.PIPE, bufsize=0, universal_newlines=True) as p: for line in p.stdout: line = str(line.rstrip()) print(line) async_to_sync(channel_layer.group_send)('logwatcher', {'type': 'chat_message','message': line}) p.stdout.flush() Please help me as to what to use and how to use it.

Django filter data using field in another model connected via foreign key
I have two models; Sets and Cards. There are many cards in one set. I would like to get it so that I can filter the cards that are returned in my tables but the set code, which for the example below is khc.

How to exclude model name and model field names from built-in error message or how translate custom error message in Django/DRF?
I have a User model with email as unique field class User(AbstractBaseUser): ... email = models.EmailField( max_length=50, unique=True, ) ... For serialization I use ModelSerializer: class UserRegisterSerializer(serializers.ModelSerializer): password = serializers.CharField( max_length=30, write_only=True ) class Meta: model = User fields = ['email', 'password'] When I attempt to create a new User instance with already taken email, I get such message in response: { "email": [ "user with this email already exists." ] } Seems like everything is ok, except the fact, that when I send request with Accept-Language in headers, I get only partially translated message, like: { "email": [ "email դաշտի այս արժեքով user արդեն գոյություն ունի" ] } As you can see there are untranslated words in message, which are email (model field) and user (model name). The question is : How to customize this message in order to exclude field name and model name and get only for example: { "email": [ "already exists." ] } If someone is going to suggest override UniqueValidator, I tell in advance: already tried that, like: class UserRegisterSerializer(serializers.ModelSerializer): class Meta: model = User fields = ['email' 'password'] email = serializers.CharField( validators=[UniqueValidator( queryset=Meta.model.objects.all(), message="already exists" )] ) password = serializers.CharField( max_length=30, write_only=True ) … -
Django one-to-many relation: optimize code to reduce number of database queries executed

How can I add image saved in the file system to the ImageField in the model?
I am trying to genera .svg QR code, save it to the file system and somehow map it with ImageField in the model. I do not really get what and how I should put into the model, so it would be "linked" with the image file. Please help me find the way. :) models.py class PinModel(models.Model): pin = models.CharField(max_length=6, unique=True) user = models.OneToOneField(CustomUser, null=True, on_delete=models.CASCADE) qr = models.ImageField(upload_to='qr/', blank=True, null=True) views.py class PinView(viewsets.ModelViewSet): queryset = PinModel.objects.all() serializer_class = PinSerializer def create(self, request, *args, **kwargs): pin = "123456" img = qrcode.make(pin, image_factory=qrcode.image.svg.SvgImage) # img is my SvgImage object img.save("qr/qrcode.svg") # now I just drop it here pin_post = PinModel.objects.create(pin=pin, user=user) # I've tried to add (qr=img) here serializer = PinSerializer(pin_post) return Response(serializer.data, status=status.HTTP_200_OK) So at this point, I have qrcode.svg in qr folder, but my PinModel is being created with Null values. I have tried to just save img, but that did not help me much. Later I am planning to generate word document with PinModel details and these svg images. How can I add image saved in the file system to the ImageField in the model? Thanks everyone!
