How to make the inventory decrease by 1 book when I borrow from the library, and increase by 1 when I return the book?
In the Book model, I made 2 methods to call them in the Borrowing field, but I haven't figured out how exactly to do it. And it is especially not clear how to connect the logic of returning the book. In the Borrowing model, there is only the actual_return_date field, when it is filled in, 1 should be added to the inventory, I think so. I tried to change the create method but it didn't work. model Book: from django.db import models class Book(models.Model): COVER_CHOICES = [("HARD", "Hard cover"), ("SOFT", "Soft cover")] title = models.CharField(max_length=255) authors = models.CharField(max_length=256) cover = models.CharField(max_length=15, choices=COVER_CHOICES) inventory = models.PositiveIntegerField() daily_fee = models.DecimalField(max_digits=7, decimal_places=2) class Meta: ordering = ["title"] def __str__(self): return ( f"'{self.title}' by {self.authors}, " f"cover: {self.cover}, " f"daily fee: {self.daily_fee}, " f"inventory: {self.inventory}" ) def reduce_inventory_book(self): self.inventory -= 1 self.save() def increase_inventory_book(self): self.inventory += 1 self.save() book/view.py from rest_framework import viewsets from book.models import Book from book.serializers import BookSerializer class BookViewSet(viewsets.ModelViewSet): queryset = Book.objects.all() serializer_class = BookSerializer book/serializers.py from rest_framework import serializers from book.models import Book class BookSerializer(serializers.ModelSerializer): class Meta: model = Book fields = ("id", "title", "authors", "cover", "inventory", "daily_fee") model Borrowing: from django.conf import settings from django.contrib.auth.models import AbstractUser from … -
Django: how to exclude certain results based on the values of other rows in the table?
I have a Django model called ProductPrice with a custom QuerySet as a manager: class ProductPriceQuerySet(models.QuerySet): def available(self, user): Group = apps.get_model("memberships", "Group") q = Q(title="Non-Member") if user.is_authenticated and user.member: q = q | Q(membership__members__user=user) return self.annotate( available=Case( When( membership_group__in=Group.objects.filter(q), then=True, ), default=False, ) ).order_by("stock", "-price") class ProductPrice(models.Model): stock = models.ForeignKey( StockManagement, on_delete=models.CASCADE, related_name="prices" ) membership_group = models.ForeignKey( "memberships.Group", null=False, blank=False, on_delete=models.PROTECT ) price = models.FloatField() objects = ProductPriceQuerySet.as_manager() This works for displaying available prices on the front end. But what I want to do is exclude the higher non-member price if the user is able to buy the item at a lower price point. What would be the best way to do this? I was thinking of another annotation like: display=Case( When( membership_group__in=Group.objects.filter(q) & ProductPrice.objects.filter( price__lt=F("price"), ), then=True, ), default=False, ) But this gives the error Cannot combine queries on two different base models. Is there an option to do this with SubQuery? Or would that be too expensive? -
Django complex filter through ManyToManyField and ForeignKey

How to make filtering with SerializerMethodField()?
I'm creating table that show objects of a model and I have a SerializerMethodField that shows a value from a different table with same transaction ID. The problem is I'm using the serializers for the filtering table and chargeback is not working in there. How Can I make it filterable?

Celery basic scheduling with apply_async is extremely slow
Scheduling tasks from Django endpoints are very slow. .delay / .apply_async of any (even dummy) task takes about 150-200ms which is terrible. Redis is up and running in docker, task is being scheduled to worker without any retries, but it takes ~200 ms just to deliver task to queue. Maybe i am missing some configuration options?

CORS Issues with Nginx as Reverse Proxy for Django
I am running Nginx as my webserver to server the static frontend files and as a reverse proxy for my Django Server. The Problem is that i am having CORS Issues, when doing request from the frontend. My Design-Plan was to use the Apex Domain example.com for the frontend and all API Calls go to api.example.com. I already did a tone of research and tried to catch OPTIONS request etc. but i still have CORS Errors. Also Django has the django-cors package installed and Axios is using .withDefaultCredentials = true.

Django Request input from User
I'm having a Django stack process issue and am wondering if there's a way to request user input. To start with, the user is loading Sample data (Oxygen, CHL, Nutrients, etc.) which typically comes from an excel file. The user clicks on a button indicating what type of sample is being loaded on the webpage and gets a dialog to choose the file to load. The webpage passes the file to python via VueJS/Django where python passes the file down to the appropriate parser to read that specific sample type. The file is processed and sample data is written to a database. Issues (I.E sample ID is outside an expected range of IDs because it was keyed in wrong when the sample was taken) get passed back to the webpage as well as written to the database to tell the user when something happened: (E.g "No Bottle exists for sample with ID 495619, expected range is 495169 - 495176" or "356 is an unreasonable salinity, check data for sample 495169"). Maybe there's fifty samples without bottle IDs because the required bottle file wasn't loaded before the sample data. Generally you have one big 10L bottle with water in it, the … -

URL Parameters to CreateView and automatic select value in a dropdown
I need, from a listview table, with an js button, open the createview and pass with parameter the id about an specific row that, in the createview form, select automatically the value in a dropdown. I imagine that, it would be with a parameter in the url of the createview and, in the createview, select in the post def the dropdown's row with the value of the parameter. Sorry if my explication it's very complicated. Examples. I have one model, Projects and I have a second model, Phases of these Projects. When I have listed the projects, from a button in one Project's row, I would need that to open the phases's createview and in the form, to select automatically the value of the dropdown's row. Projects form (the icons are bad): projects form When I click on the button with the url path('phases/add/', phasesCreateView.as_view(), name='phases_create'),, I need that in the destiny form phases form, the first dropdown would be completed automatically. -
When to run tests in dockerized django application?
I'm building a CI/CD for a django application. We dockerized the application and now our goal is to automate the building process triggered by push on a github repository. We are now building the GitHub Actions side. The project requires all containers to be running. I'm wondering where I should be running tests. Running them in the docker file seems useless as there are several tests that would fail if the other containers are not running (postgres container for example, or rabbitmq ). The approach I was thinking was to maybe setup a job in GitHub actions, build and start all containers with compose and then run the tests ? What is the recommended approach ? -
