Django app working locally anyhow when I push it to Heroke it will display a 500 error (H10)
I started my Django app with the sqlite default data base and later on I proceeded the steps (shown below) since I wanted to host it in Pythonanywhere since it was a cheaper alternative (it did not work), I sadly could not successfully deploy to Heroku as well. My project Repository looks like this: RECIPE-APP/ |-include/ |-Lib/ |-Scripts/ |-src/ |-media/recipes/ |-recipe_app/ |-settings.py |-wsgi.py |-recipes/ |-.env |-data.json |-db.sqlite3 |-manage.py |-.gitatributes |-.gitignore |-Procfile |-pyvenv.cfg |-requirements.txt I have a .env set up containing all keys for the DATABASES, in which case I copied all the required keys to heroku config vars.

Docker Deployment Issue: "unable to set PTHREAD_PRIO_INHERIT"
I am trying to deploy my Django application through Docker.

Django datetime loaded incorrectly from database
I have a Django application for viewing sensor observations. This is my observation model: class Observation(models.Model): timestamp = models.DateTimeField() sensor = models.ForeignKey(Sensor, on_delete=models.CASCADE) value = models.DecimalField(max_digits=6, decimal_places=3) In one of my views, I want to use the timestamp of the latest observation: latest_observation = Observation.objects.order_by('-timestamp').values('timestamp').first() context['latest_data_timestamp'] = latest_observation['timestamp'] if latest_observation else None The timestamp is stored correctly in the database (UTC). However, when running my view, the timestamp is changed to the timezone set in settings.py, but the tzinfo is still 'UTC'. Timezone support is enabled in settings.py: TIME_ZONE = 'Europe/Amsterdam' USE_TZ = True For example, a timestamp stored in the database as 2023-11-22 18:00:00+00:00 is loaded as 2023-11-22 19:00:00+00:00, but if I understand it correctly, it should be 2023-11-22 19:00:00+01:00. (Ignoring daylight saving time, 'Europe/Amsterdam' is UTC+1) What am I doing wrong, and how do I fix this? I tried using astimezone to set the timezone correctly, but that doesn't work. I could also simply replace the tzinfo, but it feels like a hacky solution. There's probably a better way... -

Get the latest index of each author in a message list - Python - Django
I have the following message model in Django: class Message(models.Model): appointment = models.ForeignKey(Appointment, ...) author = models.ForeignKey(User, ...) role = models.CharField(max_length=50, choices=Role.choices, ...) message = models.TextField(null=False) created_at = models.DateTimeField(auto_now_add=True) Suppose I retrieve a query set for a given appointment id: Message.objects.filter(appointment_id=id) which, for example, could be as follows: queryset = [Message_A, Message_A, Message_B, Message_A] where Message_A is from author A and Message_B is from author Β. You can distinguish the authors based on their field role, which takes values A and B. Also, the messages are sorted chronologically based on the created_at field, from oldest to newest. It is required to find the index of the last record for each author in an efficient way; in our example, for author A, it would be 3, and for author B, it would be 2. The index of one author will be the size of the queryset - 1. How do we find the index of the other author as efficiently as possible? -

How to integrate Asterisk AMI with our custom CRM to make auto-calls to customers whenever there's a new number
we developed a custom CRM where we collect user phone number and other details. Recently, our company started using IP telephony system, more specifically they are using Asterisk AMI and we wanted to integrate it with our CRM. The point of it is now our call centre is exporting the list of customers from CRM and manually calling each of them(sometimes it takes days after to call a customer in which point they already change their mind), but we want to automate it and call them after we get the customer's number in the order of LIFO. Unfortunately, I couldn't find any helpful information from the company who installed IP telephony system and other places. Can anyone help with it please? We tried to contact the people who set up the IP telephony company, they provided some materials but they are useless. And checked internet official asterisk site and other places, but we couldn't figure out how to implement it -

Making Downloaded Files a Parameter for Subsequent Functions in Django, Celery, and Digital Ocean Spaces Integration

Come effettuare una verifica dell'input dell'utente con più campi di un modello django?
Premetto che sono neofita nel mondo della programmazione e da agosto di quest'anno ho iniziato a studiare da autodidatta Python e successivamente Django. Sto cercando di implementare una view per la cui se sei autenticato come utente django e se inserisci una chiave e un numero di telefono che corrispondono con quello registrato nel database allora hai accesso ad una risorsa url specifica. Gli step sarebbero i seguenti: In Homepage c'è un button che se cliccato reindirizza alla view access_to_events_by_secret che istanzia il form con i due campi da compilare. Quindi l'utente inserisce i dati e a quel punto vengono verificati i dati inseriti e se corrispondono al numero di telefono e alla chiave presenti nel database allora si viene reindirizzati ad uno specifico URL. Ecco il codice: Models.py from django.db import models from .utils import generate_code # Create your models here. class Secret(models.Model): name = models.CharField(max_length=50) key = models.CharField(max_length=15, blank=True, unique=True) phone_number = models.CharField(max_length=13) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) def __str__(self): return self.name def save(self, *args, **kwargs): if self.key == "": self.key = generate_code() return super().save(*args, **kwargs) Utils.py import uuid def generate_code(): code = uuid.uuid4() code_mod = str(code).replace('-', '').upper()[:15] return code_mod Forms.py from django import forms from .models … -

Later I want to display on each location an average of the users s ratings. I Stored the rating of users with respect to an object in a database called "Ratings". However, when I submit, items don t get stored in the "ratings". This is the views file: `from django.shortcuts import render, get_object_or_404, redirect from django.contrib.auth.decorators import login_required from .models import Item from .forms import RateItemForm # Create your views here. def detail(request, pk): item = get_object_or_404(Item, pk = pk) related_items = Item.objects.filter(category = item.category, is_sold = False).exclude(pk=pk).order_by('-price')[0:3] items = Item.objects.filter(is_sold = False).order_by('-price')[0:6] highest_rated_item = items.first() return render(request, 'item/detail.html', { 'item': item, 'related_items' : related_items, 'highest_rated_item' : highest_rated_item }) @login_required(login_url='/login/') def rate(request, pk): item = get_object_or_404(Item, pk = pk) if request.method == "POST": form = RateItemForm(request.POST) if form.is_valid(): rating = form.save(commit=False) rating.user = request.user rating.item = item rating.save() return redirect('item:detail', pk = rating.id) else: print(form.errors) else: form = RateItemForm() return render(request, 'item/rate.html', { 'item': item, … -

Override Django Admin Save Model
I want to override Django form save method to be able to create multiple objects at once. I have an AvailableHours model : class AvailableHours(models.Model): free_date = models.ForeignKey(AvailableDates,null=True, blank=True,on_delete=models.CASCADE,related_name='freedate') free_hours_from = models.IntegerField(null=True, blank=True) free_hours_to = models.IntegerField(null=True, blank=True,) status = models.BooleanField(null=True,default=True,) and I have a ModelForm for this class : class TimeGenerator(forms.ModelForm): class Meta: model = AvailableHours fields = ['free_date','free_hours_from','free_hours_to','status'] def save(self, commit=True): base_item = super().save(commit=False) frm = self.cleaned_data['free_hours_from'] to = self.cleaned_data['free_hours_to'] items = [ AvailableHours( free_date=base_item.free_date, status=base_item.status, free_hours_from=hour, free_hours_to=hour + 1, ) for hour in range(frm, to) ] if commit: AvailableHours.objects.bulk_create(items) return items I want to create multiple AvailableHours object like this: if the form is set free_hours_from = 13 and free_hours_to=16 so the save method creates 13-14 , 14-15, 15-16 I achieved this by overriding my ModelForm but now I want to override Admin Save model to do this from Django Admin. I tried by doing it like this in admin.py class AvailableHoursAdmin(admin.ModelAdmin): def save_model(self, commit=True): base_item = super().save(commit=False) frm = self.cleaned_data['free_hours_from'] to = self.cleaned_data['free_hours_to'] items = [ AvailableHours( free_date=base_item.free_date, status=base_item.status, free_hours_from=hour, free_hours_to=hour + 1, ) for hour in range(frm, to) ] if commit: AvailableHours.objects.bulk_create(items) return items admin.site.register(AvailableHours,AvailableHoursAdmin) but no luck. anyone has a solution for this ? -
Celery Task ECS Termination Issue - Need Help Updating Decorator for Handling ProtectionEnabled State Changes
Explanation: I have a Django application where I am running multiple Celery tasks on AWS Elastic Container Service (ECS), using SQS as the broker. I am encountering an issue where the Celery tasks are being started in an existing ECS task once the previous one is completed. The issue arises because my decorator changes the status of ProtectionEnabled from true to false, and after a couple of seconds, the ECS task is terminated. The newly started task then fails to work. Below is the command I am running to start celery task. celery -A myapp_settings.celery worker --concurrency=1 l info -Q sqs-celery I am using alerts on CloudWatch to check messages in broker and terminate those ECS tasks that are completed. The problem is that celery is starting task in existing ECS task once the previous one was completed. It would not be a problem but my decorator changes the status of ProtectionEnabled from true to false and after 20 seconds ECS task is terminated and newly started task is not working anymore. Question: I am considering updating my decorator to change back the ProtectionEnabled value from false to true if a new Celery task starts, but I am unsure how … -
Using stage_block API to upload file chunk is so slow when executing under Uwsgi request in Django
I am using python 2.7.18 with azure-storage-blob==12.3.2 and Django to implement file upload with small chunk, when calling stage_block API in interactive mode directly each chunk request takes less than a second. While under Uwsgi request , it was so slow and each chunk data need almost 90 seconds to complete. What are the possible reasons? # directly calling from azure.storage.blob import BlobClient import base64 import os container = "test" blob_name = "test" blob = BlobClient(account_url=******, container_name=container, blob_name=blob_name) chunk_size = chunk*1024*1024 block_ids = [] index = 0 with open(file_path, 'rb') as f: while True: data = f.read(chunk_size) if data: length = len(data) block_id = base64.encodestring(str(index)).strip() blob.stage_block(block_id, data) index += 1 else: break resp = blob.commit_block_list(block_ids) # Django request，uwsigi wrapped from azure.storage.blob import ContainerClient container = ContainerClient(account_url=********, container_name="test") def process_chunk(request): import base64 id = request.GET['id'] idx = request.GET['idx'] data = base64.b64decode(request.POST['data']) blob = container.get_blob_client(id) block_id = base64.encodestring(str(idx)).strip() try: blob.stage_block(block_id, data) return HttpResponse(status=200, content="ok", content_type='text/plain') except Exception, ex: import traceback logger.error(traceback.format_exc()) return HttpResponse(status=500, content="failure", content_type='text/plain') The uwsgi config is like below: master = true single-interpreter = true processes = 8 enable-threads = true threads = 20 socket = /tmp/instance.sock chmod-socket = 666 listen = 8192 harakiri = 90 vacuum = true buffer-size … -
Stepwise procedure to install django,nginx,gunicorn,supervisor and virtualenv on Fedora 38
Steps: NGINX 1.Installed ningx, added a test index page at /etc/nginx/sites.d Added an include /etc/nginx/sites.d/*.conf; in the main nginx conf.d file. It worked out of the box, (I didn't go for any of the sites-available sites-enabled symnliks alternative configurations which never worked and were downright complicated) POSTGRESQL 2. Installed postgresql, created db and owner and granted privs. Now my questions on how to continue: VIRTUALENV: a) I INSTALLED virtualenv, have not CREATED it yet to anywhere nor ACTIVATED it. I read it can be created anywhere, QUESTION: I read creating a webapps dir at the root is ok? b) once I have question 3.a) cleared, next topic: CLONING THE DJANGO APP FROM BITBUCKET I have my django app at bitbucket. QUESTION: do I have to place myself where the test index page is (step 1) to start the cloning from the repository? or do I do it from the webapps dir created at 3a) ? GUNICORN Since gunicorn is a python package, it has to have the virtualenv installed before (unlike postgresql and nginx who are self-contained) Still inside the activated virtualenv, I will install gunicorn. Since the configuration is very specific I will try that first myself. SUPERVISOR 6) …
