How to auth user to Django admin site using external API end point
I'm using an external endpoint to check if the username and password are given and if it is valid I return success:true if not I return it as false. and ofc I generate a token and return it back to him. Here is the function amusing for this : @api_view(["POST"]) # decorator to make this a rest API endpoint def login_user(request): """ Login User Endpoint takes in email & password as input from the client side """ username, password = request.data["username"], request.data["password"] # authenticate function from Django auth library is used here # to check if the provided credentials are correct or not user = authenticate(username=username, password=password) # If authentication is successful then generate a token else return an error message as a JSON object if user: token, _ = Token.objects.get_or_create(user=user) the_company_object = hiring_app_company.objects.get(user=user) user_object = { "name": f"{user.first_name} {user.last_name}", "email": user.username, "image": f"https://admin.apexnile.com{the_company_object.company_logo.url}", "link":f"https://admin.apexnile.com/admin/" } return Response( {"success": True, "user": user_object, "token": token.key}, status=status.HTTP_200_OK, ) else: return Response( {"success": False, "error": "Invalid Credentials"}, status=status.HTTP_401_UNAUTHORIZED, ) The API called are being called from a totally different server which uses Next auth and it authenticates the user based on the response returned from this API call. now the problem is sometimes … -
React nginx to django gunicorn error 502 not visible on gunicorn
I'm asking this question because, despite more or less similar topics, I haven't found an answer to my problem. I have 2 servers (A and B). On server A, there is my react app using nginx to be served. On server B, there is my django drf deploying with gunicorn. Django drf is the backend of my front react app. Django is not accessible on internet but i can reach him from server A (using curl http://serverb_ip:8080). I set up react nginx conf as follow: upstream django { least_conn; server serverb_ip:8080; } server { listen 80; server_name servera_name; return 301 https://$server_name$request_uri; } server { listen 3000; listen \[::\]:3000; server_name pro.boutigou.fr; access_log /var/log/nginx/app.log; root /home/bouti/frontend/producer/build; client_max_body_size 10M; location /producer/api/v1/ { access_log /var/log/nginx/app_proxy.log; error_log /var/log/nginx/error_proxy.log debug; proxy_pass http://django; } location / { access_log /var/log/nginx/app_http.log; try_files $uri /index.html; add_header X-Frame-Options SAMEORIGIN; } } And my gunicorn set up on serverb: \[Unit\] Description=gunicorn daemon Requires=gunicorn.socket After=network.target \[Service\] User=bouti Group=www-data WorkingDirectory=/home/bouti/backend/api ExecStart=/home/bouti/backend/env/bin/gunicorn \\ --access-logfile - \\ --workers 3 \\ --bind unix:/run/gunicorn.sock \\ api.wsgi:application \[Install\] WantedBy=multi-user.target Request from react to my backend are visible in /var/log/nginx/app_proxy.log and /var/log/nginx/error_proxy.log.

CORS issue between Django backend and React frontend in Docker environment
I have a Django backend and a React frontend set up in separate Docker containers, both running on the same Docker network. The backend is accessible via the DNS backendServer and the frontend via frontendServer. I'm encountering a CORS issue when trying to make API requests from my React frontend to my Django backend. The error message in the browser console is: Access to XMLHttpRequest at 'http://localhost:8000/api/project/?page=1' from origin 'http://192.168.1.63:3000' has been blocked by CORS policy: The request client is not a secure context and the resource is in more-private address space `local`. Is there something else I might be missing or another configuration I need to make to allow requests from my React frontend to my Django backend? Any help or suggestions would be greatly appreciated. Thank you! I've tried the following steps to resolve the issue: Installed and configured the django-cors-headers middleware in my Django project. Added 'corsheaders' to INSTALLED_APPS and 'corsheaders.middleware.CorsMiddleware' to MIDDLEWARE in my settings.py file. Set CORS_ALLOWED_ORIGINS to include my frontend URL (http://192.168.1.63:3000). Ensured that my Docker containers are on the same network. Despite these steps, I'm still encountering the CORS issue. The 192.168.1.63 is my dev server that hosts the docker services. -
JSON from api request in func app encoded differently to that of a Django app
I have a Django application which contains a function that calls an API and adds the data from the response into my database. I am trying to move this function into an Azure function app, however the JSON that is returned from the request seems to be encoded differently which is causing the database insert to fail.

Add Log entry on Model Export Actions
I have enabled Log entries in the Django Admin class CustomLogEntryAdmin(admin.ModelAdmin): list_display = [ "action_time", "user", "content_type", "object_id", "object_repr", "action_flag", "change_message", ] # list filter list_filter = ["action_time", "user", "content_type"] # search search_fields = ["user__username", "object_repr"] admin.site.register(LogEntry, CustomLogEntryAdmin) And I have another model whose admin.py code is like this class RegAdmin(ExportActionMixin, admin.ModelAdmin): resource_class = RegAdminResource def has_view_permission(self, request, obj=None): return True def has_module_permission(self, request): return True By default all change, addition and deletion entries are logged but I also want to log an entry when any export action is performed on it. ChatGPT suggests that I should something like this # in admin class def export_action(self, request, *args, **kwargs): # Log the export action LogEntry.objects.create( user_id=request.user.id, content_type_id=ContentType.objects.get_for_model(self.model).id, object_id=None, object_repr=str(self.model), action_flag=1, # Assuming 1 stands for the action flag of 'change' change_message="Export action triggered.", ) return super().export_action(request, *args, **kwargs) But this function is not triggered when an export action is performed. I confirmed by adding a print statement. How should I do this? Any help would be appreciated. -

Streaming data using Langchain RetrivalQA
I am using Django, and Langchain with OpenAI to generate responses to my prompts. I was trying to enable streaming using Server-Sent-Events (SSE) in my API function. When I run my code It does stream the OpenAI output in the terminal, but it returns the output as a whole to the client once the streaming has ended. I tried using StreamingHttpResponse but, didn't get any success. It would be really awesome if any one can suggest what's wrong in the code. API Function: @api_view(['GET','POST']) def sse_view(request): if request.method != 'POST': return Response({"message": "Use the POST method for the response"}) url = request.data.get("url") questions = request.data.get("questions") prompt = request.data.get("promptName") if not url or not questions: return Response({"message": "Please provide valid URL and questions"}) # Process the documents received from the user try: doc_store = process_url(url) if not doc_store: return Response({"message": "PDF document not loaded"}) except Exception as e: return Response({"message": "Error loading PDF document"}) custom_prompt_template = set_custom_prompt(url,prompt) # Load and process documents loader = DirectoryLoader(DATA_PATH, glob='*.pdf', loader_cls=PyPDFLoader) documents = loader.load() text_splitter = CustomRecursiveCharacterTextSplitter(chunk_size=1500, chunk_overlap=30) texts = text_splitter.split_documents(documents) #Creating Embeddings using OpenAI embeddings = OpenAIEmbeddings(chunk_size= 16, openai_api_key= openai_gpt_key,) db = FAISS.from_documents(texts, embeddings) db.save_local(DB_FAISS_PATH) search_kwargs = { 'k': 30, 'fetch_k':100, 'maximal_marginal_relevance': True, 'distance_metric': … -

CSRF verification error from dockerized Django behind dockerized nginx
I have two docker containers running together, one for a Django app using gunicorn, and one for nginx serving static files and redirecting requests to the Django app. I have used different ports for the Django/gunicorn server, exposed only to nginx (8000), the nginx server, exposed in the docker container (80), and externally when using the docker container (so I mapped the port to a different one, say 8888). I also access it with a "xyz.local" host name from the device where docker runs. This is all happening in a home network, no HTTPS involved. Now when I submit a form, e.g. the admin interface's login form, I get a CSRF verification failure saying xyz.local:8888 is not a trusted origin. I understand that I can add "http://xyz.local:8888" to the CSRF_TRUSTED_ORIGINS to make it work, or disable CSRF protection altogether, but I'm wondering if that is the correct/best way in this setup. I would like to have the Django docker container be as unaware of the outside world as possible, so that I can just run it on another device having a different host name or with a different docker-compose configuration using a different port, without having to rebuild the docker … -

400 Bad Request Error in an application using Django, Gunicorn, and Nginx
I've been trying to troubleshoot my issue with no success for a while now, so I hope posting here helps. I am developing an application using Django REST Framework, Gunicorn, and Nginx. The idea is to have Gunicorn serve the Django applicaiton, and have Nginx be used as a reverse proxy that holds the SSL certs. I've referenced multiple guides on hosting applications using these three technologies, with little success. I have my Django application connected to gunicorn using a sock file on port 80, and my Nginx server blocks listen for both port 80 and 433 (for SSL purposes). I have tried just about everything I can think of, and yet I am still getting a 400 - Bad Request error whenever I navigate to the domain that should serve the API. This is my Nginx sites-available file, with just a couple of names changed for security purposes: server { listen 80; server_name www.querymarketplace.net; return 301 http://querymarketplaceapi.net$request_uri; } server { listen 80; server_name querymarketplaceapi.net 157.245.10.103; location /static/ { root /home/jbisc/qm_marketplace/; } location / { include proxy_params; proxy_pass http://unix:/home/jbisc/qm_marketplace.sock; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-Host $server_name; } } server { listen 443 ssl; listen [::]:443 ssl; # Optional: … -

A function working in a custom file but not in a "custom migration" on Django
I am beginner in Django and just started learning migrations. In a DB table, I am trying to remove a row that has a specific field value. When I create a custom file which uses Django settings, the function properly deletes the row. But when I use the snippet in another function in a custom migration file, the deletion doesn't take place. It is possible that I am missing something elementary as a beginner. So I am trying to delete all orders the status of which is cancelled. The function that works in a separate file is: os.environ.setdefault("DJANGO_SETTINGS_MODULE", "orm_skeleton.settings") django.setup() from main_app.models import Order def delete_test_fnc(): all_orders = Order.objects.all() for i in range(len(all_orders) - 1, -1, -1): order = all_orders[i] if order.status == "Cancelled": order.delete() delete_test_fnc() The custom migration where delete doesnt work (other two modifications work without issues) is: from datetime import timedelta from django.db import migrations CURRENT_ORDERS = [] def modify_delivery_warranty(apps, schema_editor): global CURRENT_ORDERS orders = apps.get_model("main_app", "Order") all_orders = orders.objects.all() CURRENT_ORDERS = all_orders for i in range(len(all_orders) - 1, -1, -1): order = all_orders[i] if order.status == "Cancelled": order.delete() elif order.status == "Pending": order.delivery = order.order_date + timedelta(days=3) elif order.status == "Completed": order.warranty = "24 months" order.save() … -

i am learning django currently and i have a question about request.user. I have made an custom user model and i use django's built in authentication. When i use login function, everything works right. When i print request.user it returns the current user. When i print request.user.password it returns the user's hashed password. I know that it is not safe to expose user's password in any form. So my question is how can i exclude password field form request.user I have tried to write a serializer but with no success. User's model from django.db import models from django.conf import settings from django.contrib.auth.models import AbstractUser, BaseUserManager from post.models import Post class UserManager(BaseUserManager): def create_user(self, email, username, fullName, password): if not email: raise ValueError("User must provide Email") if not username: raise ValueError("User must provide username") if not fullName: raise ValueError("User must provide full name") user = self.model( email=self.normalize_email(email), fullName=fullName, username=username ) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, username, email, full_name, password=None): """Create user and give Superuser privilages""" user = self.create_user( email=email, full_name=full_name, username=username, password=password ) user.is_active = True user.is_staff = True user.is_superuser = True print("Superuser privilages activated.") user.save(using=self._db) return user class User(AbstractUser): email = models.EmailField("Email", unique=True) username = models.TextField("Username", max_length=100, unique=True) fullName … -
Running DRF endpoints in a venv with gunicorn
I have some APIs implemented with DRF and I want those to run in a venv. I am using gunicorn. I run gunicorn like this: /path_to_venv/bin/gunicorn But in the API code I log os.getenv('VIRTUAL_ENV') and it's None. Is that valid evidence that the code is not running in the venv? If so, how can I force it to run in the venv? If not, how can I validate that it is running in the venv? -
Extract Musical Notes from Audio to array with FFT
I'm trying to create a project in which I upload an audio file (not necessarily wav) and use FFT endpoint to return an array with the names of the sounds. Currently, I have such code, but even though I upload a file with only the sound A, it receives the value E-10, and when uploading, for example, title, I receive only one sound. Would anyone be able to help me? import os from django.shortcuts import render from django.http import JsonResponse from pydub import AudioSegment import numpy as np from noteQuiz import settings #Names of the notes NOTE_NAMES = ["C", "C#", "D", "D#", "E", "F", "F#", "G", "G#", "A", "A#", "B"] def freq_to_number(f): return 69 + 12*np.log2(f/440.0) def number_to_freq(n): return 440 * 2.0**((n-69)/12.0) def note_name(n): return NOTE_NAMES[n % 12] + str(int(n/12 - 1)) def find_top_notes(fft, xf): if np.max(fft.real) < 0.001: return [] lst = [x for x in enumerate(fft.real)] lst = sorted(lst, key=lambda x: x[1], reverse=True) idx = 0 found = [] found_note = set() while (idx < len(lst)) and (len(found) < 1): f = xf[lst[idx][0]] n = freq_to_number(f) n0 = int(round(n)) name = note_name(n0) if name not in found_note: found_note.add(name) s = [note_name(n0)] found.append(s) idx += 1 return found def … -
Django broken pipe error when handling large file
A server developed using the Django framework is hosted in a local environment, and a broken pipe error occurs in the process of processing large files. The current problem is the code below, which is to respond by changing the DICOM file to the png extension through a separate view to deal with the DICOM file. There is no problem in normal cases, but a broken pipe error occurs when processing about 15MB of files. # javascript code for request file data in html template function loadImages(images, fileType, index) { event.preventDefault(); if (index < images.length) { var image = images[index]; var fileName = image.image_url.split('/').pop(); var imageData = { fileName: fileName, }; imageInfoArray.push(imageData); var img = new Image(); img.onload = function() { var filePreviewHTML = ` <li class="add-image-${index}"> <a href="javascript:void(0)" class="img-wrap" data-id="${index}"> <img src="${(fileName.endsWith('.DCM')) ?

Flutter Web: Assets Not Loading Correctly from main.dart.js Using Current Relative URL Instead of Base HREF
I'm currently working on hosting a Flutter web application using a Django web server on an Ubuntu 20.2 environment. The Flutter version I'm using is 3.13.5, channel stable, and my project structure has the Flutter web project located in the static folder. I've been facing an issue where the Flutter web application cannot locate the FontManifest.json file. It seems like this file is being sought using the current URL (relative) instead of the base URL defined in the index.html file. Assets loaded from index.html work correctly with the base href directed to static directory, but those loaded from main.dart.js and are using the current URL. Has anyone encountered a similar issue or has insights on how to ensure that all assets, including FontManifest.json, loaded from main.dart.js use the base URL as intended? I am almost inclined to reference the missing visual assets in main.dart through the Network module but I think Flutter should have a configuration option to determine the static-uri-location where the app will be hosted with all it's static files instead of just having to rely on the relative-uri for static files. 1.I tried fetching those 2 files (AssetManifest.bin + FontManifest.json) through the main.dart.js but that does not …
