Error in the configuration of django parameter files in VSC
Good evening, I am following a python course on the web, dictated by the Universidad Pontificia de Chile, according to the video and documentation provided by them, using django. At the moment I am configuring the parameters for the Views of django. The first web page works perfectly, but when reconfiguring the views.py and urls.py files, to take information provided by the user through the API gives the following message: Request Method: GET Request URL: http://127.0.0.1:8000/music/ Beatles Using the URLconf defined in AyudantiaMP1.urls, Django tried these URL patterns, in this order: music/ artists/<artist_id>/ [name='artist_detail'] music/ [name='index'] admin/ The current path, music/Beatles, didn’t match any of these.

Django 404 image for profile picture
I have added a new attribute to my django model that includes a imagefield attribute for profile pictures: Models.py: class AvailableDrinks(models.Model): drink_name = models.CharField(max_length=200) store_name = models.ForeignKey('Stores', on_delete=models.CASCADE,) description = models.CharField(max_length=1200) drinksSlug = models.SlugField(unique=True, null=True) photo = models.ImageField(upload_to="static/media/images/drinkPhotos", blank=True) def __str__(self): return self.drink_name Views.py: class DrinksView(generic.DetailView): template_name = "drinks.html" context_object_name = "drinks" model = AvailableDrinks slug_url_kwarg = 'drinksSlug' def get_object(self): return get_object_or_404(AvailableDrinks, drinksSlug=self.kwargs['drinksSlug']) def get_queryset(self): return AvailableDrinks.objects.all() class StoreView(generic.DetailView): template_name = "caffeine-stores.html" model = Stores context_object_name = 'stores' slug_url_kwarg = 'slug' Url.py: urlpatterns = [ path("", HomeView.as_view(), name="home"), path('<slug:slug>/', StoreView.as_view(), name="stores"), path("<slug:slug>/<slug:drinksSlug>/", DrinksView.as_view(), name="drinks"), path("<int:account_id>/select_drinks/", views.select_drink, name="select") ] print(settings.DEBUG) if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Settings.py: STATIC_URL = 'static/' MEDIA_URL = '' MEDIA_ROOT = BASE_DIR I have printed out my directories to make sure that they are properly pointing to the image files.

cant create django superuser when User model extends Abstract User
I am trying to create a custom user model by inheriting from AbstractUser.Only issue is that I am not able to create a SuperUser in my terminal.

Several Django Projects
I want to create several django projects that use the same package; can I create them in the same virtual environment won't this create conflict? the idea is that each of them can use a separate database. or would it be better to list each in its own directory?

Django & HTMX - make forms render_field a target of HTMX
I've created a django form where user can input partial name of a client. HTMX displays all matching clients and when button is pressed next to clients name, I'd like it to fill multiple form fields. Let's consider simplified Django manual form example: invoices/templates/invoice_add.html {% extends 'base.html' %} {% load widget_tweaks %} {% block content %} <form method='POST' autocomplete='off'> {% csrf_token %} <label>{{ form.number.label_tag }}</label> {{ form.number.errors }} {% render_field form.number class="form-control" %} <br> <label>{{ form.buyer_name.label_tag }}</label> {{ form.buyer_name.errors }} {% render_field form.buyer_name class="form-control" hx-post="/invoices/check_client/" hx-trigger="keyup" hx-target="#buyer_names_list" %} <div id="buyer_names_list"></div> <br> <label>{{ form.buyer_tax_no.label_tag }}</label> {{ form.buyer_tax_no.errors }} {% render_field form.buyer_tax_no class="form-control" %} <br><div id="tax_no_test"></div> <input type='submit' value='save'/> </form> {% endblock %} As mentioned above, when populating buyer_name I'm getting a list of client names with a button next to their name inside buyer_names_list. This button calls below function to pull the tax number: invoices/views.py def particular_client_invoice(request): client_obj = Client.objects.all().filter(name=request.POST.get('clientname')) context = {'client_tax_no': client_obj.values_list('tax_no', flat=True)[0]} return render(request, 'partials/specific-invoice.html', context) My issue: While it properly returns desired tax number, I can only return the values from HTMX inside a div (id="tax_no_test" in this case). I'd like field form.buyer_tax_no to be the target field of the tax number. Is that possible? Alternatively (worse … -
How do I change the URL a user copies in Django?
Building a DJANGO app. All the links on one of my pages when you click 'copy link' don't return the links URL but the GET command that I'm firing off in a custom function, for context clicking a link increments a vote counter in the app and then it redirects to the actual link, however this is preventing users from getting the URL of that link if they use right-click -> copy link in a browser. How do I intercept a 'Copy Link' request and pass the actual URL to the user? I've not been able to find any resources on the web to help me, granted I'm not sure what I'm searching has been the right keywords. -

Nginx configuration for both front-end and back-end in same file
I have an app hosted on a server with Nginx and Gunicorn. This app’s frontend is built using React while the backend Django. I do understand how to configure Nginx and Unicorn for a Django app. But what I want is every request to the ‘/admin/’ and ‘/api/‘ should be sent gunicorn, but every other request to the root url and others should be sent to the react app to handle.

The group_send in channel_layers from django does not work when running multiple times
I was learning about django-channels and wanted to create a basic timer that tells me every second, or rather sends a response to the react frontend/ client every sec as to many seconds has it been since a certain button has been clicked. But it seems that the group_send method of the channel_layer runs only the first time, but in my code the time update of the timer is in the consumer class, which i cannot access if the group_send method does not work. Here is the consumer.py file import json import asyncio from channels.generic.websocket import AsyncWebsocketConsumer from django.utils import timezone class HelloConsumer(AsyncWebsocketConsumer): async def connect(self): # Join the hello_group when a WebSocket connection is established await self.channel_layer.group_add('hello_group', self.channel_name) await self.accept() async def disconnect(self, close_code): # Leave the hello_group when a WebSocket connection is closed await self.channel_layer.group_discard('hello_group', self.channel_name) async def receive(self, text_data): # Handle the received message if text_data == 'hello': # Update the last_hit timestamp self.scope['last_hit'] = timezone.now() else: await self.send(text_data=json.dumps({'error': 'Invalid message'})) async def send_hello_message(self, event): # Send hello message to the client while True: print('hehe2') last_hit = event.get('last_hit', None) if last_hit: seconds_ago = (timezone.now() - last_hit).seconds await self.send(text_data=f'Hello World hit {seconds_ago} seconds ago') else: await self.send(text_data='Hello World … -

DUPLICATION FINDING FOR ROW BASE ON COLUMN
Looking at the table in the image we could see that the row for SNO 1 with Reference number PAP123 is a duplicate of the row for SNO 3 with Reference number PAP123. We could see that the duplication happens in the CUTTING column and that is why under the DUPLICATION column for both SNO 1 and SNO 3 there is a "True" condition and in parentheses the CERTIFICATE No. and BATCH for its duplicate is indicated together with the column in which the duplicate is happening. We could also see that under the WEEDING column duplication happens for SNO 2 and SNO 4 but it is not marked as duplicate because the REFERENCE NO. are not the same. Now I want to use this same logic to modify the code below so that the output will look for duplicates like in the table of the image. For duplicate to happen a row needs to have at least a column value repeated and the value should fall under the same column. Also, the Reference no. for both rows should be the same. duplicate_mask = combined_data.duplicated(subset=[ 'SLASHING BEFORE LINING & PEGGING', 'CUTTING OF PEGS', 'LINING & PEGGING', 'PLANTAIN /ECO TREE-HOLING', 'COCOA-HOLING', … -

Django Channels WebSocket Connection Returns 404 Not Found
I'm working on a Django project with Django Channels to handle WebSocket connections. I've set up my routing and consumers, but when I try to open a WebSocket connection from my JavaScript code, I get a 404 Not Found error. Here's my JavaScript code: var chatSocket = new WebSocket( 'ws://' + window.location.host + '/ws/chat/'); And here's my Django Channels routing: # routing.py from django.urls import re_path from . import consumers websocket_urlpatterns = [ re_path(r'ws/chat/$', consumers.ChatConsumer.as_asgi()), ] When I try to open the WebSocket connection, I get this error in the console: GET http://localhost:8000/ws/chat/ 404 (Not Found) I've also configured Django Channels to use Redis as the channel layer in my settings: # settings.py CHANNEL_LAYERS = { 'default': { 'BACKEND': 'channels_redis.core.RedisChannelLayer', 'CONFIG': { "hosts": [('127.0.0.1', 6379)], }, }, } I've checked and double-checked my routing and everything seems to be in order. What could be causing this error? How can I debug this issue? Any help would be appreciated. -
Django save() is not properly saving my object
I have two models one named Post and the other Journey. Each Journey contains a query set of Post objects. When I add a post to the posts of Journey and save both the new Post and the Jounrey, the post does save properly but the Journey doesn't. The Post is beign properly created because in my JourneyView it is displayed after it is created but when I refresh the Post no longer appears as part of the Journey. I checked the database manually and the new post is saved and the object does exist it is just not being saved as part of the Journey. This is the function I am using to create the post: #Create post @api_view(['POST']) def post_create(request): form = PostForm(request.POST) attachment = None attachment_form = AttachmentForm(request.POST, request.FILES) #journeys = Journey.objects.filter(created_by_id=request.user.id) #journey = Journey.objects.get(id = post.journeyID) if attachment_form.is_valid(): attachment = attachment_form.save(commit=False) attachment.created_by = request.user attachment.save() if form.is_valid(): post = form.save(commit=False) post.created_by = request.user post.save() journey = Journey.objects.get(id = post.journeyID) #journey.posts.set(journey.posts.all()) journey.save() #save_Journey(post.journeyID) if attachment: post.attachments.add(attachment) user = request.user user.posts_count = user.posts_count + 1 user.save() serializer = PostSerializer(post) return JsonResponse(serializer.data, safe=False) else: return JsonResponse({'error': 'add somehting here later!...'}) I already tried using a for loop to save … -
How to obtain a queryset from unrelated models in Django
I am developing a website on car spare parts. The main model is Part, which has different parent models, such as Category and Brand. I want to automatically generate the menu from my database. If I had one level menu, "Category", this is pretty straightforward. I just select all categories, which have at least one part in them, and pass them to the template in the context: category_list = Category.objects.annotate(num_parts=Count('parts')).filter(num_parts__gt=0) context['category_list'] = category_list return context But now I want my menu to be two-level, consisting of categories and brands: Wheels Toyota Ford Renault Radiators Ford Mersedes Or course, I don't want to obtain empty menu options, where are no parts. Please give me a hint, how can I do this! -

django OneToOneField to abstract object
i want a field be OneToOneField to an abstract object, the abstract will be never used, instead will be used subclasses: from django.db import models class Abs(models.Model): useType = True absName = models.CharField(max_length=10, default='mickey', blank=True) class Meta: abstract = True from django.db import models from .abs import Abs class Sub(Abs): useType = False name=models.CharField(max_length=10, default='', blank=True) from django.db import models from .abs import Abs class ParentClass(models.Model): abs = models.OneToOneField(Abs, on_delete=models.CASCADE) but when make makemigrations i receive following error: books.ParentClass.abs: (fields.E300) Field defines a relation with model 'Abs', which is either not installed, or is abstract. books.ParentClass.abs: (fields.E307) The field books.ParentClass.abs was declared with a lazy reference to 'books.abs', but app 'books' doesn't provide model 'abs'. If Abs was a real object all works fine, but Abs should never be a real object, so i thought should be abstract, it's only a basket to common info/methods, an interface. Is there a way to do that?

Django - dynamic filtering multiple querysets

Dynamically change used database table while django app is running?
I want to create a service that has a page to configure a data base table (columns and types) and that allows to CRUD lines in it via the page. The content of that table should then be used for comparison with payload of rest api call. I am quite new to django and don't know if that approach is possible with the django ORM. What I saw so far is that one defines the database scheme hardcoded and I didn't see how I can make my concept running with this. If not I am thinking about representing and managing this dynamically created table via a json or likewise object that is stored in an object database. -
