Running Daphne with a Configuration File Similar to Gunicorn in Django - How to Specify Configuration Options
I am working on a Django project and have successfully used Gunicorn with a configuration file (lu_development/gunicorn.conf.py). I am able run my server using this command. gunicorn -c lu_development/gunicorn.conf.py lu_development.wsgi:application Now, I need to switch to Daphne for ASGI support, but I'm unsure about how to specify configuration options for Daphne, similar to what I did with Gunicorn. How can I run Daphne with a configuration file? What is the equivalent Daphne command to gunicorn -c lu_development/gunicorn.conf.py lu_development.wsgi:application? Are there any specific parameters or considerations when using a Daphne configuration file? I would appreciate any guidance or examples on running Daphne with a configuration file, and any insights on differences or similarities between Gunicorn and Daphne configuration setups. Thanks! -
Swagger UI customization in DRF (Django) using drf-spectacular
I am currently trying to document apis of my DRF project. I have read many articles on how to customize swagger api definition . I have found out that i can use extend_schema() and serializers to customize api definitions. But the problem is i have to 100s of APIs in my project. and using extend_schema() i will have to edit 100s of files. Is there a way to define all APIs in a single file ? like for this example : https://editor.swagger.io/ there is a yml file, where we can edit all API definitions. is there something similar that i can do for my DRF project ? -

Slow Performance with Django and Remote PostgreSQL on Docker - Local vs. Production Environment
I'm encountering a significant performance issue with my Django application when using a remotely hosted PostgreSQL database in a production environment. My setup involves a Django application running locally and connecting to a PostgreSQL database hosted on a server. Local Environment: Both Django and PostgreSQL are running locally. Operations, such as importing 1000 rows from an Excel file, are almost instantaneous. Production Environment: Django is running locally, but PostgreSQL is hosted on a server with the following specs: 4 CPUs, 16GB RAM. The same operation takes about 3 minutes. Docker Compose for Production (docker-compose.prod.yml): version: '3.8' services: db: env_file: - .env image: postgis/postgis:16-3.4 command: ["postgres", "-c", "config_file=/etc/postgresql.conf"] volumes: - postgres_data:/var/lib/postgresql/data - ./postgresql.conf:/etc/postgresql.conf - ./pg_hba.conf:/etc/pg_hba.conf environment: - POSTGRES_USER=${POSTGRES_USER} - POSTGRES_PASSWORD=${POSTGRES_PASSWORD} - POSTGRES_DB=${POSTGRES_DB} restart: unless-stopped networks: - db_network ports: - "5432:5432" healthcheck: test: ["CMD-SHELL", "pg_isready -U ${POSTGRES_USER}"] interval: 10s timeout: 5s retries: 5 # Other services like backup, pgadmin, etc. networks: db_network: driver: bridge volumes: postgres_data: driver: local driver_opts: type: none device: /var/database/postgres_data o: bind Observations: The server doesn't seem to be under heavy load (low CPU and sufficient RAM).

Django: Upload Image to database
I am trying to upload an image from input field but when I check from database (using Value in Editor), it shows blank both binary and text.

Capture Coordinates on PDF in React.js - Similar to DocuSign clone
I'm working on this project which kind of similar to DocuSign. User will upload a pdf and drags and drops textboxes and will save it as templates. I need to store the x and y coordinates along with the label for that textbox. And when the user re-opens the template, he has to see the pdf along with the fields placed on the pre-set coordinates. This info is used in the backend to generate the output pdf using a python script. I'm done with the python script part and planning to use this in django. I don't know how to achieve the coordinates grabbing part. I researched a bit and found a couple of libraries "react-pdf" for pdf viewing and "react-dnd" for drag and drop. Can I achieve the requirement using these two libraries? If you have any other better suggestions, please let me know. Thank you so much in advance. -

Django channels start runworker with same consumer multiple times and automatically init all workers
I am trying to build up a more or less scalable infrastructure with django channels: I have a consumer called sendConsumer which is connected via wss to server A and everytime I send a signal to that consumer from django it forwards it to the server A. Then I have a consumer called receiveConsumer which is connected via wss to server B where I retrive thousends of events per second. However now I want to scale this approach up and have multiple background consumers (so multiple wss connections to server B) and the documentation is unfortunally very quite about this. And yes I really need django channels and not a task queue: In my case django channels is the best approach rather than using celery or similar as I want to be able to send updates to the workers from a django view or a signal to update parameters on the fly. My idea to solve that issue was to create multiple systemd files that have their own environment variables and therefore every worker can start with its own id. In addition with that I modified the apps.py to send an inital message to the worker to basically wake it … -
How to Structure Models and Forms
I'm working on a Django app to track scoring for Golf. I'm currently spinning my wheels on how to structure my models and forms for a scorecard form. I've found forms to be a bit more difficult than I thought they would be. I'm trying to figure out if i'm going about this the right way? i've thought about combining the GolfRound and GolfHole into one model, but it feels kind of wrong to have a field for each hole. I'm leaning towards a nested inlineformset, but i'm not sure if that's the right approach. Here are my models: ***MODELS*** class TeeTime(models.Model): updated = models.DateTimeField(auto_now=True) timestamp = models.DateTimeField(auto_now_add=True) activity = models.ForeignKey(GolfActivity, on_delete=models.CASCADE, related_name='event_teetime') tee_time = models.TimeField(auto_now=False, auto_now_add=False, blank=True) players = models.ManyToManyField(GolfTripMember, blank=True, through='TeeTimePlayers') class GolfRound(models.Model): tee_time = models.ForeignKey(TeeTime, on_delete=models.CASCADE, related_name = 'round') golfer = models.ForeignKey(GolfTripMember, on_delete=models.CASCADE, related_name = 'round_player') gross_score = models.IntegerField(null=True) net_score = models.IntegerField(null=True) par_3 = models.BooleanField(null=True, default=False) complete = models.BooleanField(null=True, default=False) active = models.BooleanField(null=True, default=False) class HoleScore(models.Model): name = models.IntegerField(choices=INDEX, default = INDEX[0][0]) par = models.IntegerField(null=True) HCP_index = models.IntegerField(null=True) netscore = models.IntegerField(null=True, blank=True) grossscore = models.IntegerField(null=True, blank=True) Any thoughts on my model structure, and approaches I should take to implement the form?

Django - Office 365 send message via distribution group
I'm trying to send email in Django using a distribution group as a the DEFAULT_FROM_EMAIL setting. I am using Office 365 to send it. I have wrestled with the package called django-o365mail and python-o365to get it to a functional state. The documentation for that was pathetic enough. I'm not interested in learning miniscule details to send an email message via Office 365 or any other third party platform that believes it has all the answers. It ought to be straightforward, and we have chosen as an industry to make it hard. [Rant over.] Here are my appropriate settings: DEFAULT_FROM_EMAIL = "distribution_list@example.com" EMAIL_BACKEND = 'django_o365mail.EmailBackend' O365_MAIL_CLIENT_ID = env('O365_MAIL_CLIENT_ID') O365_MAIL_CLIENT_SECRET = env('O365_MAIL_CLIENT_SECRET') O365_MAIL_TENANT_ID = env('O365_MAIL_TENANT_ID') O365_ACTUALLY_SEND_IN_DEBUG = True O365_MAIL_MAILBOX_KWARGS = {'resource': 'distribution_list@example.com'} I have tried various ways of achieving my goal, and here are some error messages to guide your thought processes on an incorrect path that you may believe to be the solution to everything. Remember, I just want to send an email to a distribution group from that very group. 404 Client Error: Not Found for url: https://graph.microsoft.com/v1.0/users/distribution_list@example.com/sendMail | Error Message: The requested user 'distribution_list@example.com' is invalid.

Card showing underneath header when page loads on phone (CSS)
I'm designing a website, and want the div named card to load underneath the header when loading the website on mobile devices, but when I lower the card's position on the page, it applies the same repositioning on the desktop version as well.

Django : automatic retry of failed database operations
Database operations can fail because of temporary network errors or because the database is temporarily unavailable. Is there a way to automatically retry the operation in these cases ? The documentation of Google's managed database offering states that connection pooling systems should reconnect to the database if a connection is in a bad state, and applications should retry a database transaction if an error app in the middle of a transaction. (See https://cloud.google.com/sql/docs/postgres/manage-connections, section "Exponential backoff") How can I implement this advise using Django? I'm currently having problems with views that successfully perform some database operations but randomly encounter a connection error during a subsequent database operation. How can I retry the database operation so that the view is finally rendered successfully?
