Deploying Django Rest Framework Based Microservices That Communicate with Token Authentication
I am developing a docker based application. The application has two components. A core component (CORE) and an interface component (INTERFACE). The world communicates with the INTERFACE component. The INTERFACE component CRUD the database in the CORE component. The ultimate aim of this setup is that I might have different interface components. Also, it applies separation of concerns. When deploying the app. Using docker compose I will establish the communication between the two applications. However, the INTERFACE should communicate with the CORE using Token Based Authentication. My question is how to generate a Token for the INTERFACE inside the CORE during launch. I tried developing a script that generates the token. But it turns out the script requires some Environmental variables that Django Shell sets. -

How to serialize a related model at depth 2 without serializing intermediate model at depth 1?
I have three models with foreign keys in this direction Order -> Customer -> User. I would like to write a view set for orders that serializes the corresponding user without the intermediate customer. Models: class Order(models.Model): customer = ForeignKey("customers.Customer") class Customer(models.Model): user = ForeignKey("users.User") class User(models.Model): name = CharField(max_length=64) Serializer: class UserSerializer(ModelSerializer): class Meta: model = User fields = ["name"] class OrderSerializer(ModelSerializer): user = UserSerializer(source="customer__user", read_only=True) class Meta: model = Order fields = ["id", "user"] View set: class OrderViewSet(ModelViewSet): queryset = Order.objects.all() serializer_class = OrderSerializer Desired output: [ {"id": 1, "user": {"name": "John"}}, {"id": 2, "user": {"name": "Mary"}}, ] Actual output: [ {"id": 1}, {"id": 2}, ] It works fine if I go via the intermediate customer serializer: class CustomerSerializer(ModelSerializer): user = UserSerializer(read_only=True) class Meta: model = User fields = ["user"] class OrderSerializer(ModelSerializer): customer = CustomerSerializer(read_only=True) class Meta: model = Order fields = ["id", "customer"] but then the output contains the intermediate customer object: [ {"id": 1, {"customer": {"user": {"name": "John"}}}, {"id": 2, {"customer": {"user": {"name": "Mary"}}}, ] -

How to integrate third party SOAP API (product data) with an eCommerce store?
I have access to a SOAP web service with over 40 thousand products and need an eCommerce store to connect the web service. The trick is that it cannot store the data locally in the eCommerce platform, and every time there is a search request, the SOAP web service must be called. Which platform would work in this case (Shopify, BigCommerce, Adobe Commerce, etc), or does it require a website built from scratch using a framework such as Django? I tried using Shopify a while back, but I couldn't find a way for it to work without storing products. -
Django apscheduler running thrice at one time
I have a scheduler code that running every minute to send notifications using fcm... I used print statements to know where the issue is, it came to be at scheduler side I saw that it was getting called thrice. I called the backgroundscheduler in apps.py, that generally runs twice so I tried with: urls, admin, models & views.py but strangely those files were also printing twice. I can't understand why... So I used File lock in apps.py: import os from django.apps import AppConfig import threading class MobileapisConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'MobileApis' _lock = threading.Lock() _initialized = False def ready(self): with self._lock: if not self._initialized: lock_file = '/tmp/scheduler_initialized.lock' if not os.path.exists(lock_file): self.initialize_schedulers() with open(lock_file, 'w') as f: f.write('initialized') self._initialized = True def initialize_schedulers(self): from . import seduler seduler.start() seduler.start1() seduler.start2() seduler.start3() print('Schedulers started') but that doesn't seems to work even the file is created with text... The scheduler logs are 3+ times at the same time... What's The best place that will call scheduler only one time? -

Raise message from a class in models.py in django
I have models class for Inventory Transfers or Issues Details. In the save method, i am accessing current stock level in a different model class for WarehouseStockStatus. I wish to message to the user from models.py if transferred or issued quantity exceeds current inventory levels. I am using django admin screens only. Print method will not work. Raise Validation error doesn't work. Also Messages will not work as it works only in views and templates where you have Request object. Any suggestions on how to proceed ? I expect to print the message to the user. -
Why are my ECS tasks pausing for six hours on startup?
I have a Fargate ECS task that runs a Django app via gunicorn. That task successfully started a few weeks ago and had no issues. It was then replaced by routine AWS maintenance/updates. The replacement task started successfully, but it paused during the execution of the entry point script for longer than the load balancer healthcheck grace period. The task of course failed the health check and that caused ECS to again stop and replace the task. This then happened endlessly, with each replacement task having the same issue. There have been no code changes involved in the Docker image used for the task. I obviously expected no change to the ECS task and that it would run as it did before. After implementing the ECS task deployment circuit breaker to stop the endless task replacement cycle, I left the paused (but running) ECS task alone for a while. I realized from the Cloudwatch logs that the task pauses for exactly six hours each time while in the middle of running the entry point script. Here's the entry point script: set -euo pipefail cd /home/viewer/projects/server || exit export DJANGO_SETTINGS_MODULE=viewer_server.settings export PYTHONPATH="/home/viewer/projects/server/" echo "DJANGO_SETTINGS_MODULE and PYTHONPATH set." python manage.py makemigrations python … -
Create CSV file from converting Json Output into CSV either using Pandas or CSV/Json Library in Django
I am struggling to figure out how to get my already made Json output and also create a csv file from that output. For more clarification, I have created a json file by using write, but I am unsure on how to also create a CSV file during the same process. Maybe I am just not inputting the CSV code in the correct area, or if Django needs some other form of method to process that request. utils.py import json import os import pandas as pd from django.utils import timezone from django.http import HttpResponse from django.db.models import Q from api.models import BlockedList def get_ip_list_json() -> dict: json_response = { "version": "", "description": "", "objects": [ { "name": "", "id": "", "description": "", "ranges": ["2.2.2.2"], }, ], } group_map = {} for ip in BlockedList.objects.filter( Q(end_date__isnull=True) | Q(end_date__gte=timezone.now()) ).select_related("group"): group_id = str(ip.group.id) if group_id not in group_map: group_map[group_id] = { "name": ip.group.name, "id": ip.group.group_id, "description": ip.group.description, "ranges": [], } group_map[group_id]["ranges"].append(ip.address) json_response["objects"] = list(group_map.values()) return json_response def create_ip_file(): try: base_dir = "C://Users/Steven/Desktop" filename = "blocklist.json" full_path = os.path.join(base_dir, filename) with open(full_path, "w") as f: f.write(json.dumps(get_ip_list_json(), indent=4)) except Exception as e: print(e) That is my above code where I create my Json output … -
redis and celery tasks works fine without docker, but using docker the tasks status is always in pending state in my django app
I am trying to write a background task to count the total number of posts. It works fine when I start redis server and celery without using docker but using docker, the tasks state is always pending.

What I can do to get the approximated price for the cloud service
I have an application to run in a server in a specific domain and I want to know how much I'm gonna pay each month in Heroku. It's a website running in python/django to solve the schedulling problem. My user will log-in and fill the form and run the solution. After running the solution they will get the results via a specific page. Is this enough information so I can get an approx. price to pay? If not, what other information I need to reveal in order to get this estimate? I tried to get the estimate using the Heroku calculator, but I got an estimate of $250 dollars per month. I included in the calculator the advanced plan with performance M. I'm not sure if that is all or not. -
Django cannot be recognized
I am doing a coding course where I'll be learning all about Django. From this, it is correct to assume that I am new to everything Django. In the course, I am at the point where I must install Django. The instructor said to use my computer's terminal to install Django. He also said to install Django 2.0.2, as that is the version he would be using. The command he had me use was pip3 install django==2.0.2. Everything installed normally, but when I tried to open Django with Django-admin, I was met with this error: django: The term 'django' is not recognized as a name of a cmdlet, function, script file, or executable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. I tried uninstalling Django, then installing the latest version using: pip install Django, but even though everything installed perfectly, I am still met with the same error when I try to start a new project with Django. I was also given alternate commands that the Bing AI Copilot gave me, such as: python -m Django startproject first_project, but that produced the same type of error. … -

How to retireve details by related onetoonefield in Djang Rest Framework?
Hello consider the following simple scenario: class User(models.Model): email = ... fname = ... lname = ... class UserPreferences(models.Model): user = models.OneToOneField(User, to_field="email", ...) preferences = ...

Storing clients card Django
I need to store customer loyalty cards. It should be flexible. I have several variants of cards with different discount systems. For example, the card by amount of purchases - > $100 - 5%, > $1000 - 10%, etc. Or by amount of visits - > 10 - 3%, 100 - 10%, etc. Furthermore, it should store the different image for different types of cards and sales amount, for example 5% - silver colour, 10% - gold, etc. I came up with the idea of storing in in database as JSON. Visits for example: schema = {1: {'discount': 5%, image: '....', 'style': {'background': ..., 'foreground': ...}, 2: {'discount': 10%, image: '....', 'style': {'background': ..., 'foreground': ...}, 3: {'discount': 15%, image: '....', 'style': {'background': ..., 'foreground': ...}, } class ABSCard(models.Model): title = field work_place = field .... class Discount(models.Model): type = .... schema = JSONField abscard_id = ABSCard But I'm not sure that storing JSON in PostgreSQL is the best way. -
