How to Customize Validation Error Response in Django REST Framework?
I am developing a RESTful API using Django REST Framework (DRF) and I need to implement a common error handling mechanism for various validation errors that occur throughout the application, including but not limited to JWT authentication failures. when validation errors occur, DRF returns default error responses that may not be user-friendly or consistent across different endpoints. For example, a JWT token validation error produces a response that looks like this: { "detail": "Given token not valid for any token type", "code": "token_not_valid", "messages": [ { "token_class": "AccessToken", "token_type": "access", "message": "Token is invalid or expired" } ] } I would like to standardize the error responses throughout my application to improve the user experience. Specifically, I want to create a common function that can return a structured error response for all validation errors in the following format: { "status": false, "responseCode": 0, "message": "Validation ", "data": {} } I tried by creating custom_exception_handler def custom_exception_handler(exc, context): response = exception_handler(exc, context) if response is not None: custom_response_data = { 'status': False, 'responseCode': 0, 'message': 'Validation error', 'data': {} } if isinstance(response.data, dict): errors = {} for field, detail in response.data.items(): if isinstance(detail, list): errors[field] = detail[0] if detail else 'Invalid … -
Django Progress bar for the backend to later integrate with frontend

Apache Superset embed Dashboard with Guest Token in DJango
I have the following setup. I'm running a Django Application with Postgres and Apache Superset on the same network (through docker-compose). The setup works fine; I can access my data (Postgres) from both the Django application and Superset. I have created a dashboard in Superset with some data and want to embed it on a DJnago page. I have already enabled dashboard sharing and I can use an iFrame to do so. However, this works because I have an active tab in the same browser with Superset, which I'm logged in to. If I go to another browser, the embedded Superset dashboard will show the login page. This is logical. However, how can manage a guest login from my Django application to the Superset so my users won't receive Superset's login page? I've tried the following code, in which I'm using Superset Guest Token API, I managed to receive a token successfully but every time I'm going to access the following URL, I'm redirected to Superset's login page with a red message "Access Denied". http://localhost:8088/superset/dashboard/1/?access_token=TOKEN/?standalone=4 <- 1 is the dashboard ID import requests import json url = "http://127.0.0.1:8088/api/v1/security/login" headers = { 'Content-Type': 'application/json' } payload = json.dumps({ "username": "guest_username", "password": … -
Django: Custom BaseInlineFormSet. Extra forms
I'm trying to implement an inline for the Product model admin, so that in addition to the forms for existing ProductAttribute relationships, forms for all attributes of the category of the product currently being edited are also added by default. The problem is that while the forms are there, saving doesn't result in creating the ProductAttribute relationship in the database, and the cleaned_data of these forms is empty. My code: admin.py ... class ProductAttributeInline(admin.TabularInline): model = ProductAttribute formset = ProductAttributeInlineFormset extra = 0 fields = ('attribute', 'value') readonly_fields = ('attribute',) can_delete = False def has_add_permission(self, request, obj=None): return False @admin.register(Product) class ProductAdmin(admin.ModelAdmin): list_display = ( 'name', 'category', 'price', 'sku', 'created_at', 'updated_at' ) search_fields = ('name', 'sku') list_filter = ('category',) inlines = (ProductAttributeInline,) ... forms.py from django import forms from .models import ProductAttribute class ProductAttributeInlineFormset(forms.models.BaseInlineFormSet): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) if self.instance and self.instance.pk: category = self.instance.category if category: attributes = category.attributes.all() existing_attributes = set( self.queryset.values_list('attribute', flat=True) ) for attribute in attributes: if attribute.id not in existing_attributes: form_index = ( len(self.forms) + len(existing_attributes) - 1 ) form = self._construct_form( instance=ProductAttribute( product=self.instance, attribute=attribute, ), i=form_index ) self.forms.append(form) self.total_forms = len(self.forms) I noticed that 'attributes-TOTAL_FORMS' in form.data is equal to 1, but … -

How Can I Setup Celery in my Flask Project
So I've been working on a project for a couple months now and I've been trying to implement Celery into my flask project and it has not gone well. I thought maybe it's my computer or windows or something like, and all the responses I've seen are from a couple years ago and I don't think that they would still work because those were the ones I tried using. So thank you for any responses in advance. I tried using the celery config from the documentation and some chat gpt tutorials but they haven't been of help. And I'm running redis on the localhost -

How to Attach Files from a web app to Local Outlook Client?
I'm working on a task where I need to implement a button in the frontend that opens the local Outlook client to compose an email. The user selects files (.dat or .csv) in the frontend, and upon clicking the button, Outlook should open with a default message and the selected files already attached, allowing the user to review the email before sending it. I understand that it might be easier to send the emails directly from the application, but that’s not the desired approach for this project. Can you please let me know if this is even possible, and if so, how I could implement it? I’ve tried using the Outlook API, but it didn’t meet my needs because it doesn’t open Outlook before sending the email, which is a key requirement for this project. Additionally, I cannot use links; the files must be attached directly as they are. -

Django Channels: WebSocket Consumer event handling method doesnt get trigerred
I'm working on a Django project using Django Channels with Redis as the channel layer. My setup allows WebSocket connections, and I am able to send and receive data from Redis without issues. However, when I try to send data to specific WebSocket channels using self.channel_layer.send, the send_online_users method in my AsyncWebsocketConsumer is not triggered. I’ve verified that my Redis server is working and communicating with the Django server. The channels and users are being stored correctly in Redis. The self.channel_layer.send() function runs without throwing errors, but the send_online_users method is never triggered (the print statements inside send_online_users do not show in the logs). Here is my Consumers.py code: from channels.generic.websocket import AsyncWebsocketConsumer import redis from django.conf import settings import redis.client from asgiref.sync import sync_to_async import json from channels.layers import get_channel_layer redis_client = redis.StrictRedis(host=settings.REDIS_HOST, port=settings.REDIS_PORT, db=0) class UserActivityConsumer(AsyncWebsocketConsumer): async def connect(self): self.user = self.scope['user'] if self.user.is_anonymous or not self.user.is_authenticated: await self.close() else: self.channel_name = f'user_activity_{self.user.username}' await sync_to_async(redis_client.sadd)('online_users', self.user.id) await sync_to_async(redis_client.sadd)("online_channels",self.channel_name) await self.accept() await self.send_to_all() async def disconnect(self,close_code): user_id = self.scope['user'].id await sync_to_async(redis_client.srem)("online_users", user_id) await sync_to_async(redis_client.srem)("online_channels", self.channel_name) await self.send_to_all() async def send_to_all(self): try: online_users = await sync_to_async(redis_client.smembers)("online_users") online_users = [int(user_id) for user_id in online_users] online_channels = await sync_to_async(redis_client.smembers)("online_channels") channel_layer = get_channel_layer() … -

Django ` [ERROR] Worker (pid:7) was sent SIGKILL! Perhaps out of memory?` message when uploading large files
My dockerized Django app allows users to upload files(uploaded directly to my DigitalOcean Spaces). When testing it on my local device(and on my Heroku deployment) I can successfully upload small files without issue. However when uploading large files, e.g. 200+MB, I can get these error logs: [2024-09-29 19:00:51 +0000] [1] [CRITICAL] WORKER TIMEOUT (pid:7) web-1 | [2024-09-29 19:00:52 +0000] [1] [ERROR] Worker (pid:7) was sent SIGKILL! Perhaps out of memory? web-1 | [2024-09-29 19:00:52 +0000] [29] [INFO] Booting worker with pid: 29 The error occurs about 30 seconds after I've tried uploading so I suspect it's gunicorn causing the timeout after not getting a response. I'm not sure what to do to resolve it. other than increasing the timeout period which I've been told is not recommended. Here is my code handling file upload: views.py: @csrf_protect def transcribe_submit(request): if request.method == 'POST': form = UploadFileForm(request.POST, request.FILES) 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 session_id = str(uuid.uuid4()) request.session['session_id'] = session_id try: transcribed_doc, created = TranscribedDocument.objects.get_or_create(id=session_id) transcribed_doc.audio_file = uploaded_file transcribed_doc.save() ... except Exception as e: # Log the error and respond with a server error status print(f"Error occurred: {str(e)}") return HttpResponse(status=500) ... else: return HttpResponse(status=500) else: form = … -
Why does my Celery task not start on Heroku?
I currently have a dockerized django app deployed on Heroku. I've recently added celery with redis. The app works fine on my device but when I try to deploy on Heroku everything works fine up until the Celery task should be started. However nothing happens and I don't get any error logs from Heroku. I use celery-redis and followed their setup instructions but my task still does not start when I deploy to Heroku. Here is my code: heroku.yml: setup: addons: plan: heroku-postgresql plan: heroku-redis build: docker: web: Dockerfile celery: Dockerfile release: image: web command: python manage.py collectstatic --noinput run: web: gunicorn mysite.wsgi celery: celery -A mysite worker --loglevel=info views.py: from celery.result import AsyncResult task = transcribe_file_task.delay(file_path, audio_language, output_file_type, 'ai_transcribe_output', session_id) task.py: from celery import Celery app = Celery('transcribe')# @app.task def transcribe_file_task(path, audio_language, output_file_type, dest_dir, session_id): print(str("TASK: "+session_id)) #rest of code return output_file celery.py: from future import absolute_import, unicode_literals import os from celery import Celery from django.conf import settings os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings") app = Celery("mysite") app.config_from_object("django.conf:settings", namespace="CELERY") app.autodiscover_tasks() I ensured that my CELERY_BROKER_URL and CELERY_RESULT_BACKEND are getting the correct REDIS_URL from environment variables by having it printing it's value before the task is to be started. So I know that's not … -
Google Login with Django and React
I am trying to integrate google login with Django and React (Vite) but I keep getting an error.
