Django field formatting within template defined within the field
I have a custom field called Percentage which I would like displayed in Django templates always with a % sign, so if the DB is holding a Float of 100.00 then in the template it would always render as 100%. I know I can write a template tag however I would like this change to be made globally so I don't need to do template tags everywhere. I've seen packages like dj-money do this so that 1 is formatted as $1 automatically. I've looked at the code but can't see exactly how this is occuring. I've investigated methods like to_python, __str__ and __unicode__ on the field but these don't appear to work. How can I customise the field to always format a particular way in string based situations like django templates and django admin? At present I've just created a custom method per field on the model to do the formatting, however I fee like there should be a way to set this on the field level. Thanks for your help -
Why is my Django view not automatically downloading a file
My view transcribes a file and outputs the SRT transcript. Then it locates and is supposed to auto download theT transcript but nothing happens after transcription completes(the file was submitted on a previous page that uses the transcribeSubmit view. The view that handles and returns the file is the initiate_transcription view). Here is my views.py: @csrf_protect def transcribeSubmit(request): if request.method == 'POST': form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): uploaded_file = request.FILES['file'] fs = FileSystemStorage() filename = fs.save(uploaded_file.name, uploaded_file) request.session['uploaded_file_name'] = filename request.session['uploaded_file_path'] = fs.path(filename) #transcribe_file(uploaded_file) #return redirect(reverse('proofreadFile')) return render(request, 'transcribe/transcribe-complete.html', {"form": form}) else: else: form = UploadFileForm() return render(request, 'transcribe/transcribe.html', {"form": form}) @csrf_protect def initiate_transcription(request): if request.method == 'POST': # get the file's name and path from the session file_name = request.session.get('uploaded_file_name') file_path = request.session.get('uploaded_file_path') if file_name and file_path: with open(file_path, 'rb') as f: path_string = f.name transcribe_file(path_string) file_extension = ('.' + (str(file_name).split('.')[-1])) transcript_name = file_name.replace(file_extension, '.srt') transcript_path = file_path.replace((str(file_path).split('\\')[-1]), transcript_name) file_location = transcript_path with open(file_location, 'r') as f: file_data = f.read() response = HttpResponse(file_data, content_type='text/plain') response['Content-Disposition'] = 'attachment; filename="' + transcript_name + '"' return response else: #complete return render(request, 'transcribe/transcribe-complete.html', {"form": form}) def transcribe_file(path): #transcription logic JS: const form = document.querySelector('form'); form.addEventListener('submit', function (event) { event.preventDefault(); const formData = … -
Django Rest Framework: AttributeError when attempting to serialize Elasticsearch InnerDoc
I am working on a Django project with Elasticsearch, using django-elasticsearch-dsl to create documents from my models. I have set up my documents and am trying to create a serializer for my Contest model. However, when I send a GET request to my endpoint (http://localhost:8000/search/offices/economia/), I encounter the following error: AttributeError at /search/offices/economia/ Got AttributeError when attempting to get a value for field `organization` on serializer `ContestSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `InnerDoc` instance. Original exception text was: 'InnerDoc' object has no attribute 'organization'. Here are my document and serializer definitions: document.py: from django_elasticsearch_dsl import Document, fields from django_elasticsearch_dsl.registries import registry from core.models import Contest, Organization @registry.register_document class ContestDocument(Document): organization = fields.ObjectField(properties={ 'id': fields.IntegerField(), 'name': fields.TextField(), # ... other fields }) # ... rest of the code serializers.py: from rest_framework import serializers from core.models import Contest, Organization class OrganizationSerializer(serializers.ModelSerializer): # ... code class ContestSerializer(serializers.ModelSerializer): organization = OrganizationSerializer() class Meta: model = Contest fields = "__all__" It seems like, for some reason, an Elasticsearch InnerDoc instance is being passed to the ContestSerializer instead of a Contest model instance, causing the AttributeError. I'm not sure why this is happening or how … -
Syncing django default/auto-generated id/createdAt/updatedAt fields with prisma schema?
I have a database which is queried by both a python django app and a nextjs app. I use the Django ORM to maintain the models and migrations, then use prisma db pull to pull in the schema from the database to keep nextjs in sync. default/auto fields don't seem to persist over, e.g. # django model, my canonical model definition class Production(models.Model): # production companies that host parties, e.g. Taylorfest id = models.UUIDField(primary_key=True, default=uuid.uuid4) createdAt = models.DateTimeField(auto_now_add=True) # prisma schema, generated from prisma db pull model party_production { id String @id @db.Uuid created DateTime @db.Timestamptz(6) in particular, while the default/auto fields are present on the django model definition, prisma's schema doesn't include the @default(uuid()) and @default(now()) upon pulling in the schema. (I'm using postgres for the database). do the django defaults happen on the django-side rather than the DB side? Does that mean using django ORM to canonically define schemas is incompatible with other apps that may need to do writes? -
How to make django load static files from a built react project
This is my project structure, I have already finished both the backend and frontend in Django and React. To host my project, I built React and loaded 'index.html' as a template, while the built CSS and JS are used as static files. backend ----backend ----base ----frontend ----build ----static ----css ----js ----media index.html // other files like favicons and JSON ----node_modules ----public ----src ----staticfiles ----db.sqlite3 -----manage.py Here is my settings.py to handle static files: STATIC_URL = '/static/' MEDIA_URL = '/media/' STATICFILES_DIRS = [ BASE_DIR / 'frontend/build/static/css', BASE_DIR / 'frontend/build/static/js', BASE_DIR / 'frontend/build/static/media', ] MEDIA_ROOT = BASE_DIR / 'static/images' STATIC_ROOT = BASE_DIR / 'staticfiles' When I turn DEBUG = True, the site runs on port 8000, but the images need to be re-uploaded to the database because it can't find those images after I built the React project. When I turn DEBUG = False, I get the following error in the console: Refused to execute script from 'http://127.0.0.1:8000/static/main.1d564988.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled. The same problem occurs for the CSS files. I tried hosting the site, but I can't load the static files. -

Store for loop queryset into one
I currently have an array with multiple objects. The for loop does a queryset based upon the array objects using a for loop of a model. search_post = ["1990", "2023"] for query in search_post: vehicle_result = Vehicle.objects.filter( Q(title__icontains=query) | Q(details__icontains=query) | Q(year__icontains=query) | Q(notes__icontains=query) ) print('vehicle_result: %s' % vehicle_result) The issue I'm having is when the array has multiple items it's going through the for loop for each object and it's outputting each objects result. Only the last object result is retained if I call this variable elsewhere in the code. Example Output: vehicle_result: <QuerySet [<Vehicle: BMW>]> vehicle_result: <QuerySet [<Vehicle: Toyota>, <Vehicle: Mercedes>, <Vehicle: Honda>]> I want to store/combine them all into one variable - prevent losing all the results (right now only the last one is retained I guess because the variable is overwritten) How can I achieve? -

how to render URL patterns in Django with multiple apps
I am trying to build a booking system, using Django. I have multiple apps and rendering the urls patterns has been difficult to understand and i have found the documentation little help when you have multiple apps.

Docker-Compose - Frontend service cannot use endpoint from backend
Context I am currently working on a multi-container project involving react, django, and (eventually) several datastores all containerized and tied together with docker-compose.

How to break a long line of html code into multiple lines as "\" will do in python and C/C++
Suppose that I have the following code, <p>aaa<a>bbb</a>ccc</p> the rendered web page will be like this However, when the text "aaa", "bbb", "ccc" becomes pretty long, I want to split this single line into multiple lines for readability, like <p> aaa <a> bbb </a> ccc </p> But the rendered web page will be like There are whitespaces between two blocks of text. How can I make these lines work as the single line mentioned before. In python or C/C++, I can simply use "\" to notify the consecutive lines should be treated as a single line. Is there a similar funtionality in html file? Besides, as I'm using django template system, I tried the django official tag "spaceless". According to django's doc, "spaceless" tag should remove the whitespace between html elements. But in this case, the whitespace between two blocks of text remains. I get pretty puzzled about this. Thanks for any help! I tried to ask chatgpt, github copilot and search on google. But I found no functionality in html that can make consecutive lines work as a single line.

Django Passkeys and NextJs
I would like to create an app based on Django and NextJS 13 that uses an authentication system using Passkeys.

I am therefore looking for a solution that will allow me to use passkeys as my login system. -
How to add permissions from URL path parameter to DRF ViewSet?
I have an app that uses url paths like the following: account/<ACCOUNT_PK/project/<PROJECT_PK>/ When using Django permissions, the permissions of the last parameter (in this case project) are checked, but also want to ensure permissions are checked for Account too. curl -s -u test:password \ -H 'content-type: application/json' \ -X POST -d '{"name": "new_project", "account": 3}' \ 127.0.0.1:8000/account/3/project/ In this example I need to check permissions for both the data given in the request, and the parameters in the URL. I have solved this by creating a valid_account method for the serializer class, and also a custom permission inherited from rest_framework.permissions.BasePermission, but it is very dependent on paths not changing. Is there an option that I'm missing or third party package that can do this? I have tried different permissions classes, or adding app.change_account to permissions_required in the ProjectViewSet, but only get errors. -

django simple history customising Base Class
I would like to start tracking changes made to a model using django-simple-history. I have a big model but would only need to track the history of a couple fields. I could use the exclude_fields parameter, but as the model gets larger, I do not want to manually keep on adding items that need to be excluded. I would like the basemodel history returns to be only the selected fields (bonus if history is only saved when one of these two fields changes, but not required).
