Django & dependency injection
In the past, I've used dependency-injector, but it looks like it's unmaintained now. :-( Does anyone have any good suggestions for a DI package? I'd want to be able to inject dependencies into views, with the ability to inject mocks in view tests. -

How to set manifest_storage for ManifestFilesMixin (Django)
I use django-storages to serve my static files from S3. I want to use the ManifestFilesMixin for cache busting my CSS and JS files. The following works fine: from django.contrib.staticfiles.storage import ManifestFilesMixin from storages.backends.s3boto3 import S3Boto3Storage class ManifestS3Storage(ManifestFilesMixin, S3Boto3Storage): pass Except that staticfiles.json is placed in my S3 bucket. I don't want this as explained here. The Django docs mention that it is possible to give a "manifest_storage" argument to the ManifestFilesMixin but I don't know how to do this. The docs mention how to do it for the ManifestStaticFilesStorage class but I don't understand how to do this for the ManifestFilesMixin. -

Railway Error when deploying DJango App due to botocore dependency (boto3)
After installing boto3 package to integrate with AWS S3 buckets, the application fails on deployment. The Railway error is "botocore 1.34.93 depends on urllib3<1.27 and >=1.25.4; python_version < "3.10". On the local server (127.0.0.1:8000) everything works fine, and app deployed with no issues before installing boto3. Upon installing boto3, I expected the app to deploy on Railway as it did before installing the package. Any suggestions? -
I get this error when sending a POST request: MissingSchema: Invalid URL 'None/orders': No scheme supplied. Perhaps you meant https://None/orders?
I'm getting this error when I use Insomnia to send a POST request to an API of my backend code (which is running on my desktop) when I try to create an order. But when I send the same request to the API of the backend running on our test server it works. What is causing this error ? It seems to me that it has something to do with the configuration of my Insomnia but I'm not sure. From what I've read on Stack Overflow it can be caused by not prefixing the URL with http:// or https:// but my URL does have http://. Thank you in advance to anyone who can offer advice.

I am trying to host my PostgreSQL database on Supabase from my Django project. I had success a few weeks ago with the same tech stack.

`request` parameter in Django - HTTPRequest or WSGIRequest
All of Django documentation says request is of type django.http.request.HTTPRequest. I use NGINX -> Waitress WSGI in my development, and I see see request is django.core.handlers.wsgi.WSGIRequest which inherits directly from HTTPRequest. I understand that Django must always run under WSGI, if so a request will always be WSGIRequest. So why does Django documentation always use HTTPRequest? -

Problem when styling django form fields upon errors
I have a bug I've been trying to fix for months but can't figure out. I'm building a website with Django. The site has a form, that, among other fields, has a field to input the name (called "nombre") and a field for the last name (called "apellido") of the user. I've declared a CSS rule (applied to the fields with the class "error" that gives a specific style to the fields that didn't pass the form validation, highlighting them in red. In a "forms.py" file, I wrote some code that assigns the class "error" to the fields that did not pass the validation. The problem is that, when I input invalid data into the "apellido" field and try to submit the form, both de "apellido" and "nombre" fields get highlighted in red. I have no clue why this could be happening. I figure it must be something with the "forms.py" file, where I assign the "error" class to the invalid fields. Here is the code of the "forms.py" file: from django import forms from .models import Turno class TurnoForm(forms.ModelForm): class Meta: model = Turno fields = ['nombre', 'apellido', 'email', 'fecha', 'hora'] widgets = { "nombre": forms.TextInput(attrs={"class": "form-control", "name": "nombre"}), … -
Dockerizing django app with Nginx, gunicorn and docker-compose - data base connectivity issue
Amateur programer here. I usually can google my way out of every issue but I struggle with the huge diversity in set ups for docker (and honestly feel al ittle overwhelmed). I am aware the the biggest tutorials out there (including the famous digitalocean one), but it didn't help. As title says, I am trying to dockerize a django app (in order to deploy to a VPS) using Nginx en gunicorn. My docker-compose file has a data base service, a django_unicorn service and a nginx container. The data base and nginx containers seem to set up correctly. But when my django_unicorn runs, in fails to connect to the data base. The error message is : django.db.utils.OperationalError: (2003, "Can't connect to MySQL server on 'db' ([Errno 111] Connection refused)")] After a while, it stops and gives me the localhost server to connect to, but it obviously shows nothing. I tried checking on the data base within my docker container. It is working fine and I connect within it with root user and my custom user. I uses the exact same credentials in my settings.py file in django. The HOST and PORT look ok to me (referring the db service in docker-compose … -
Override CSS when Debug=True
In order to avoid confusion between my production and development instance (where DEBUG = True), I'd like to override the CSS of my bootstrap Navbar in development (only) to show up e.g. in red instead of blue. What is the most elegant way to accomplish this? I can override get_context_data() everywhere to include my settings.DEBUG, or inherit from a newly generated base classes, but that doesn't seem very DRY. -
Display a converted .docx to PDF file from Django REST framework backend in React frontend
I am running a django REST framework backend and a React frontend. I want to convert a .docx to PDF bytes in the backend and display it on the frontend but I keep getting Failed to load PDF Document error. I have tried several pdf modules and different methods to display the PDF bytes in the frontend but I keep getting the same error. I will really appreciate any help . Below is what I came up with: views.py from docx import Document @api_view(['POST']) def viewFile(request): data = request.data file = File.objects.get(id=data['id']) try: pdf_bytes = convert_file_to_pdf(file) pdf_base64 = base64.b64encode(pdf_bytes).decode('utf-8') return Response({'pdf_base64': pdf_base64}) except Exception as e: return Response({'error': str(e)}, status=status.HTTP_500_INTERNAL_SERVER_ERROR) def convert_file_to_pdf(file): if file: if file.filename.endswith('.docx'): doc = Document(file.file) pdf_bytes = BytesIO() doc.save(pdf_bytes) pdf_bytes.seek(0) return pdf_bytes.read() elif file.filename.endswith('.xlsx'): wb = load_workbook(file.file) # Convert to PDF using appropriate method (e.g., Excel to PDF) # Return PDF bytes elif file.filename.endswith('.pptx'): prs = Presentation(file.file) # Convert to PDF using appropriate method (e.g., PowerPoint to PDF) # Return PDF bytes else: raise ImproperlyConfigured("Unsupported file format") else: raise ImproperlyConfigured("File not found") DocumentViewer.js function DocumentViewer() { const [fileId,] = useState('327'); const [pdfUrl, setPdfUrl] = useState(null); useEffect(() => { const getPdf = async () => { try … -
How to store my user-uploaded files on Digital Ocean Spaces using django-storages?
I am totally new to this. My Django app is run in Docker. My app allows users to upload files which are stored, followed by executing some functions on the file then generating a new file that the user can download. I'd like to store the initial user-uploaded file and the output-file my django code generates. Here is my code: models.py: class TranscribedDocument(models.Model): id = models.CharField(primary_key=True, max_length = 40) audio_file = models.FileField(upload_to='ai_transcribe_upload/', null= True) output_file = models.FileField(null= True) date = models.DateTimeField(auto_now_add=True, blank = True, null=True) views.py: #save uploaded file if form.is_valid(): uploaded_file = request.FILES['file'] request.session['uploaded_file_name'] = uploaded_file.name request.session['uploaded_file_size'] = uploaded_file.size#add to models.py session_id = str(uuid.uuid4()) request.session['session_id'] = session_id transcribed_doc, created = TranscribedDocument.objects.get_or_create(id=session_id) transcribed_doc.audio_file = uploaded_file transcribed_doc.save() request.session['uploaded_file_path'] = transcribed_doc.audio_file.path #generate new file with open(file_location, 'r', encoding=charenc) as f: file_data = f.read()## transcribed_doc, created = TranscribedDocument.objects.get_or_create( id = request.session['session_id'] ) transcribed_doc.output_file = transcript_path transcribed_doc.date = timezone.now() transcribed_doc.save() settings.py: DATABASES = { "default": { "ENGINE": "django.db.backends.postgresql", "NAME": "postgres", "USER": "postgres", "PASSWORD": "postgres", "HOST": "db", # set in docker-compose.yml "PORT": 5432, # default postgres port } } AWS_ACCESS_KEY_ID = 'key_id' AWS_SECRET_ACCESS_KEY = 'secret_key_id' AWS_STORAGE_BUCKET_NAME = 'name' AWS_DEFAULT_ACL = 'public-read' #change to private AWS_S3_ENDPOINT_URL = 'https://nyc3.digitaloceanspaces.com/' # Make sure nyc3 is correct AWS_S3_OBJECT_PARAMETERS = …
