Passing data from Django to React
Im trying learn django and react and im doing so by trying to create a web app using spotify api to display top tracks and top artists for users.

Django Crontab Job Not Executing Within Docker Container
I am facing an issue with running Django crontab jobs within a Docker container. The crontab jobs work perfectly in my local development environment, but when I dockerize my Django app and attempt to run it within a container, the crontab jobs do not seem to execute as expected. Here's a breakdown of the setup and the problem I'm encountering: Local Development (Working): In my local development setup, I have added the following configuration to my Django settings: THIRD_PARTY_APPS = [ "django_crontab", ] CRONJOBS = [ ("* * * * *", "apps.{path}.jobs.deactivate_expired_enrollments"), ] This configuration sets up a crontab job that deactivates expired course enrollments. The crontab job works perfectly in this environment. Docker Setup: To dockerize my Django app, I've created a Dockerfile and a start.sh script as part of my Docker Compose configuration: Dockerfile: # Install apt packages RUN apt-get update && apt-get install --no-install-recommends -y \ # Installing cron cron \ RUN touch /var/log/cron.log RUN (crontab -l ; echo "* * * * * echo 'Hello world' >> /var/log/cron.log") | crontab # Run the command on container startup CMD cron && tail -f /var/log/cron.log start.sh: #!/bin/bash set -o errexit set -o pipefail set -o nounset python manage.py … -
I have an issue with i18n and custom error handling in Django
I am implementing custom error handling in Django, and I have an issue with the '404 Not Found' error. Essentially, when I access http://localhost:8000, I am redirected to the 404 error page. However, if I type http://localhost:8000/en/, I am redirected to the homepage. What I want to achieve is to be redirected to the homepage even by simply typing http://localhost:8000. In the main urls.py I've defined the urlpatterns in the following way: urlpatters = i18n_patterns( ... ) and handler404 = "baseApp.views.error_404" Do you have any suggestion? I tried changing LANGUAGE_CODE from "en-us" to "en" but it didn't work -
Sorting Many to Many relationship in django doesn't work
I've been trying to implement a sorting solution for so long and nothing has worked so far. I have a Email list and email model. There is a many to many relationship between them.

I tried annotation. Same result. I used ChatGPT to come up with a solution he also couldn't give me the solution. Same solution would work on one to many relationship but not on many to many. Please help me figure out a view for this. Thanks a lot. -

Django admin login csrf error only on https
My django application is working fine both on locally and on server with http. But when I am enabling https for my domain it stops working and giving me csrf error. Once again.

SIgning users in Django through Google OAuth and using that data to access their Gmail

DRF Create list of objects even when some of them not valid
I'm currently working on a DRF project where I'm dealing with a scenario where I receive a list of objects through a POST request. The challenge I'm facing is that this list might contain some objects that are not valid according to certain criteria. However, I need to go ahead and create all the valid objects, and then perform a bulk creation of all these valid objects in one go. I've tried a few approaches, but I'm running into issues with properly validating and handling the objects, especially when using a many=True, if one of the items are not valid than no items created at all. Has anyone encountered a similar situation or can provide insights on how to approach this? Any guidance on how to correctly structure the validation, filtering, and bulk creation process would be greatly appreciated! Thank you in advance. Here is the code I've managed to write, but it doesn't look right to iterate over objects in the view: @action(methods=['post'], detail=False, url_path='custom_method') def custom_method(self, request): created = [] for item in request.data: serializer = self.get_serializer(data=item) try: serializer.is_valid(raise_exception=True) except ValidationError: # ... make log continue self.perform_create(serializer) created.append(serializer.data.get('id')) # custom action for created objects ... return Response(...) -

Docker & Django: Django is looking for a DB table before running migrations
When I run docker-compose, all containers start without errors except "catering-django-1". As I understand it, django looks for the "myapp_menu" table in the DB before running the migrations. However, everything works for me locally. That is, when I write "python3 manage.py migrate" in the console - everything works flawlessly. I can't figure out what the problem is for a long time and I hope for your help. Thank you!

Django celery is not processing the task
I am trying to tigger a process that runs in the background. I am calling this process using ajax call. I have setup celery/rabbitmq/flower to achieve this. In my app ->views.py def sync_now(request,sync_id): sync_obj=Sync.objects.get(id=sync_id) synchronize_data.apply_async(args=[sync_id]) result = synchronize_data.apply_async(args=[sync_id]) # Get the task ID task_id = result.id print("task id") return render something Tasks.py app = Celery('sync', broker='pyamqp://xxx:xxxx@localhost:5672/myvhost') @shared_task def synchronize_data(sync_id): try: sync_obj = Sync.objects.get(id=sync_id) # Your synchronization logic goes here sync_data(sync_id, sync_obj) return 'Success' # Return a result to indicate success except Exception as e: return str(e) # Return an error message in case of failure When I run this command - celery -A ipass worker -l info --pool=solo -- it appears like all the queued process gets triggered and sync_data is called multiple times. I had to manually kill the cmd But when I trigger this from the template I get only [2023-08-26 23:08:26,320: INFO/MainProcess] Task sync.tasks.synchronize_data[0c72b00b-acf1-48d2-ab44-6ddb678d62e8] received [2023-08-26 23:08:26,320: INFO/MainProcess] Task sync.tasks.synchronize_data[7c2c018f-cd6b-4dae-8cab-b18a572a5c92] received [2023-08-26 23:08:26,887: INFO/SpawnPoolWorker-32] child process 10588 calling self.run() [2023-08-26 23:08:26,888: INFO/SpawnPoolWorker-33] child process 11024 calling self.run() I am unable to debug, what is missing here ? Please let me know if you need more information.
