Using Django Channels (websocket layer consumer) to update a webpage with data from an internal database and external an data source
I have the following django channels class which updates values on a webpage webpage. The class receives data from screen clicks, performs actions (toggling indicdual relays or setting a series of them for a particular use, updates a databse and then updates the webpage via a websocket layer. All this worked fine until I introduced nina. This receives data from a remote source via a curl POST (see below).

(Django jwt token) get specific user with user id
Current I am retrieving user data with the UserViewSet like this: class UserViewSet(viewsets.ModelViewSet): queryset = Account.objects.all() serializer_class = UserSerializer permission_classes = (IsAuthenticated,) What I did was to make a GET request the via the endpoint `http://localhost:8000/account/auth/user/${id}` together with a Bearer jwt Token on the header. However, I realized that I can get the all the user with the same jwt token because of the Account.objects.all(), which is not I wanted at all. I want to get the specific user corresponding to their id with their unique jwt token. Anyone has an idea how to do it? Thanks a lot. -
psycopg2 NotNullViolation on column "ip" for Django/Gunicorn/Nginx system
I have a Django system that has gunicorn hosting the dynamic content and nginx the static, nginx passing through to gunicorn as required via a Unix socket. Every request that requires static content is generating an error like that below. Is this because the request comes from a Unix socket and not via IP? How do I fix this?

MongoDB driver to support most Django functionality
As per the project requirment, I have to use Django + MongoDB. I am super new to Django (not good in Django's ORM too) but have good experience with MongoDB. My project is about storing a lot of Schemaless data and then making analysis reports or use for machine learning etc. MongoDB states PyMongo as official driver for Python projects but, there are bunch of other drivers also available like mongoengine, djongo, motor etc. After reading a lot of articles, still I can't find simple answer to my question: WHICH DRIVER SUPPORT MOST OF DJANGO FUNCTIONALITY About Djongo, This link states that: because it supports all django contrib libraries. Using Djongo, all we need to do is setting up and changing the models base import, no need to worry about changing serializers, views, and all other modules. If I use PyMongo, will I miss any advantage of Django except ORM? I am open for suggestions and critisism as i just started learning this... -

How to share database details in Github correctly, using Django and PostgreSQL?
I have an assignment in which I need to set up a database server using Python Django and PostgreSQL. I need to assign the project in Github, and the grader will use my repository to check my project. In my setting.py file I have the following lines: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'CourseDB', 'USER': 'postgres', 'PASSWORD': '123', 'HOST': 'localhost', 'PORT': '5432' } } What to do so the details on my file will be correct for the grader's side? Will they have to create a database with the given name, user and password like the ones in my file? I think that maybe for the database name, I can add in the readme to run CREATE DATABASE CourseDB first. But then again, I don't know their user and password on their machine, So I don't know what should be written in my file in order for my code to work on their machine. I followed this tutorial on YouTube to create my file. -
Order and OrderItem Logic
I'm working on an inventory management project for a warehouse selling items in bulk. I'm a having hard time figuring out the logic for my orders (Dumb me). What I have at the moment is an Order model and an OrderItem model, the basic idea is that a single order, might contain multiple items with default or custom pricing. Here's my Order model class Order(models.Model): creation_date = models.DateTimeField(auto_now_add=True) customer = models.ForeignKey(Customer, on_delete=models.CASCADE) paid_amount = models.IntegerField(default=0) def __str__(self): return f'{self.creation_date.strftime("%Y%m%d")} - {self.customer.full_name}' def get_absolute_url(self): return reverse('order-detail', kwargs={'pk': self.pk}) @property def is_fully_paid(self): # Couldn't figure out how to write the rest. Here's my OrderItem model class OrderItem(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) order = models.ForeignKey(Order, on_delete=models.CASCADE) quantity = models.IntegerField(default=1) custom_single_product_price = models.IntegerField(blank=True, null=True) def __str__(self): return f'{self.creation_date.strftime("%Y%m%d")} - {self.customer.full_name} - {self.product.title}' Here's my Product model class Product(models.Model): creation_date = models.DateTimeField(auto_now_add=True) title = models.CharField(max_length=128) sku = models.CharField(max_length=30, blank=True, null=True) photo = models.ImageField(upload_to='product_photos/', blank=True, null=True) number_of_boxes = models.IntegerField(default=1) number_of_products_per_box = models.IntegerField(default=1) single_product_price = models.IntegerField(default=1000) def __str__(self): return self.title def get_absolute_url(self): return reverse('product-detail', kwargs={'pk': self.pk}) a product already has a single_product_price which should be used as the default price at checkout, however, managers at the warehouse are able to customize that default to something else entirely … -

Django-ordered-model doesn't let me update models
I was trying to figure out Django and the ordered model but when I updated my model 'something' from models.Model to OrderedModel things got weird. So I had a variable TextField under my model 'something' which already had migrations and stored data, but due to the update from models.Model to OrderedModel the existing data presented issues with the migration. The error is as shown-- You are trying to add a non-nullable field 'order' to a resource without a default; we can't do that (the database needs something to populate existing rows). Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a null value for this column) 2) Quit, and let me add a default in models.py Can you help me out? I don't want to lose my data. -
