Can't see any results from Celery Beat in Django Project
I want to run scheduled tasks in my django backend with celery and celery beat. I have a Dockerfile config for both celery container beside the normal django container.

setting acks_late=True doesnt re-execute the task if worker process is killed
i want to reproduce this behaviour highlighted in celery doc If the worker won’t shutdown after considerate time, for being stuck in an infinite-loop or similar, you can use the KILL signal to force terminate the worker: but be aware that currently executing tasks will be lost (i.e., unless the tasks have the acks_late option set). this is my task: @shared_task( name='CHECK_ACK', acks_late=True, ) def check_ack(): print('task picked') time.sleep(60) print('task completed after 60r seconds') here are steps i am following: 1.start celery: celery -A master worker --concurrency=2 2.run the task from django shell: check_ack.delay() 3. while task is running execute :pkill -9 -f 'master worker' 4. now restart celery again : celery -A master worker --concurrency=2 But i don't see the task getting re-picked by workers. What am i missing? -

A problem occurs when adding a new foreign key field to a model
So, I added a foreign key field to my model, ran "makemigrations" and "migrate" without problems, but when I check my database via DB browser, I cannot find that field! This is my model class Listing (models.Model): CATEGORY_CHOICES = [ ("chemistry", "Chemistry"), ("physics", "Physics"), ("math", "Math"), ("litreture", "Litreture"), ("history", "History"), ("language", "Language"), ("sports", "Sports") ] title = models.CharField(max_length=80) brief = models.CharField(max_length=128) description = models.TextField() intial_price = models.IntegerField() category = models.CharField(max_length=24, choices=CATEGORY_CHOICES) # The problem is within the line below creator = models.ForeignKey(User, on_delete=models.CASCADE, related_name='listings') # I cannot find this field in my database file when browsing it via DB browser def __str__(self): return self.title I tried to ask the AI a lot but all it said was to check the migrations files and make sure the migration process is successful. I am sure that there is no issue with those two. I ran out of ideas, help! -
Best place to initialize a variable from a postgres database table after django project startup
I have a django project where I have some database tables. One of the database tables is designed to store messages and their titles. This helps me to create/alter these messages from my django-admin. Now I want to initialize a variable (as a dictionary) from this table as follows : MY_MSGS = {record.name : {'title':record.title, 'message':record.message} for record in MyTable.objects.all()} This must happen at the server startup for now. MY_MSGS must be accessible to the different view-files. FYI I have multiple view-files that are all imported from views.py -
Django API JSONfield fetches an object that I can't use .map to parse and then build a chart
I have a Django serialized API field that contains database JSONfield data that creates a chart (this data is confirmed to work on my Flask backend), but I can't use the same data taken from a Django API ''' // data.data.linechart: "[{'index': 1295395200000, 'Strategy': 28.8935858208}, {'index': 1304035200000, 'Strategy': 33.3317284202}]" fetch(url) .then(response => response.json()) .then(data => { var dataArray = Object.keys(data.data.linechart).map(function(key) { return [key, data.data.linechart[key]]; }); // Convert the array of key-value pairs to a format that supports map var mapData = dataArray.map(function(item) { return { index: item[0], Strategy: item[1] }; }); const series = [ { name: 'Strategy', data: mapData } ]; //Apex Chart var optionsChart = { series: [{ name: 'New Data', data: series }], What am I missing here? Fetch is pulling serialized API data as an object - and the conversion above isn't working. Have others seen the same problem? I have tried: JSON.parse(data), JSON.stringify(data), Stripping brackets: const dataArray = data2.data.linechart.replace('[', '').replace(']', ''); but I cannot convert the chart data JSON from an Object - without splitting the JSON string into individual characters... -

ModuleNotFoundError attempting to load development settings
I'm very new to Django, so please excuse my rookie question. I understand the need to separate the development configuration from the production one. And so I have created a folder at br_project/br_project/settings/ and in it I have these files: - __init__.py - base.py - development.py - production.py The br_project/br_project/__init__.py file contains: import os env = os.environ.get('DJANGO_ENV', 'local') if env == 'production': from .production import * else: from .development import * When .development is called, I get an error: ModuleNotFoundError: No module named 'br_project.production' Somehow my configuration files are not being found. What have I set up wrong? -

Unable to retrieve Authjs (NextAuth 5) access token server-side in Next.js 15 with Django backend
I'm trying to set up authentication in my Next.js application using NextAuth.js with a Django backend. As Oauth provider i'm use django-oauth-toolkit. The goal is to pass the access token in the Authorization header when making requests to the Django API. I have successfully set up the OAuth2 provider in Auth.js, and I'm able to log in through the Django authentication system.

if condition with field value don't work in Django template

Get table changes details without using triggers in postgres
I am working on a live dashboard which records changes in database and shows details related to it on the dashboard. Currently to get these live changes I am using a combination of triggers, functions and pg_notify to generate notifications from postgres when some tables have CRUD operations in them. All of this is working okay for now, but based on some suggestions I read online many people do not recommend to use triggers if it is possible, as they are hard to maintain and don't sit best with rest of our code base. So for this reason I want to try updating my trigger based approach with something which fits with my code better and easier to maintain. But I don't know what I can use instead of triggers to get live changes from database. Most triggers in my database are just used to send postgres notification back to my backend where I am handling the changes directly, so if I can get the changes from the database without using triggers I think I can make it work, but I can't figure out how to do so. Also, if you think that trigger based approach is better for my … -

Buffer channels when there are no consumers
When a channel has no consumers, can I get django to buffer all the messages sent on the channel instead, then after a consumer subscribes can I get it to send all the buffered messages again (to that consumer)?

How to log all errors related to an API request in Django Rest Framework along with multiple fields in a CSV file?
I want to log any type of error that occurs during an API request in Django Rest Framework into a CSV file, including the error message along with additional details like username, user ip, url, etc. I also want to capture errors that occur before reaching the view (e.g., errors related to JWT). I tried using middleware for this, but the issue was that some responses were not rendered correctly, and even after manually rendering, they still resulted in errors. I would appreciate it if you could suggest a solution. The code below is the middleware I tried to use. I don't have an issue with logging errors that occur inside the view because if I only wanted to log errors within the view, I could use decorators or create a custom APIView. However, what I'm looking for is a way to log any type of error, even those that occur outside the view. class ErrorLogMiddleware: def __init__(self, get_response): self.get_response = get_response self.filename = settings.ERROR_LOG_PATH self.fieldnames = ["Username", "IP", "User Agent", "Date/Time", "Time Interval", "Query", "Message", "URL"] def __call__(self, request): if not exists(self.filename): with open(self.filename, "a", newline="", encoding="utf-8") as csvfile: writer = DictWriter(csvfile, fieldnames=self.fieldnames) writer.writeheader() before = time() try: response … -

Django re_path to catch all URLs except /admin/ not working properly
I'm trying to define a re_path in Django that catches all URLs except those that start with /admin/.

Django 5 translate route with param
I have troubles to translate properly a route that needs a param. this works fine if the uri has /fr/ or /en/: urlpatterns = [ path(_('CATEGORY'), views.category, name='app-category'), ] But as long as I need to add a param like: urlpatterns = [ path(f"{_('CATEGORY')}/<slug:uuid>", views.category, name='app-category'), ] or urlpatterns = [ path(_('CATEGORY') + "/<slug:uuid>", views.category, name='app-category'), ] The translation stuck with 'category' so the route /fr/categorie/ is not working. _('CATEGORY') = 'categorie' for fr or 'category' for en.

How to reset specific container child tags from tailwind styles
