Delete Tasks using Django framework
Im currently creating a todo list project using the Django web framework and i currently have an issue with deleting tasks of the webpage. My issue is that i don't know and can't find suitable code to perform the action of deleting a task from the webpage. This is what the webpage looks like: todo list. I believe my issue is contained in the views.py file: from django.shortcuts import render, redirect from django.contrib import messages as django_messages from django.contrib.auth import authenticate, login as auth_login, logout as auth_logout from django.contrib.auth.decorators import login_required from django.contrib.auth.models import User from .forms import RegisterForm, CreateTask from .models import Task # Import Task model def home(request): if request.method == 'POST': form = CreateTask(request.POST) if form.is_valid(): form.save() return redirect('home') else: form = CreateTask() tasks = Task.objects.all().order_by('-created_at')[:10] # Query Task model correctly context = { 'form': form, 'tasks': tasks, } return render(request, "home.html", context) def delete_task(request, id): task = Task.objects.get(id=id) task.delete() return redirect('home') @login_required def user_logout(request): auth_logout(request) django_messages.success(request, 'Logged out successfully') return redirect("introduction") # Redirect to a valid URL name def user_login(request): if request.method == "POST": username = request.POST.get("username") password = request.POST.get("password") user = authenticate(request, username=username, password=password) if user is not None: auth_login(request, user) django_messages.success(request, 'Login successful') return … -
Integrity Error raised because of constraint cannot override In Django Admin Panel

How to prevent Gmail from altering image URLs in email HTML?
I'm working on an event management portal using Django, and I send a confirmation email upon user registration. The email includes a masthead image.

Choosing the Right Architecture for Django Application: Monolith vs. Microservices [closed]
Project Idea: All-in-One School Portal Hi there! I need to build project for a school system which idea is collecting different existing sites (different sizes and technologies). Here's what it will offer: Student Dashboard: Students can log in to view their personal information, subject details, exam scores, and class schedules (including location, teacher, and room). Assignments: Both teachers and students can access the assignment section. Teachers can upload assignments, while students can submit their answers. Teachers can also grade submissions and leave comments. Additional Features: The portal will include other functionalities like teacher ratings and exam applications. Choosing the Right Architecture (Microservice vs Monolith) 1. Microservice vs Monolith I'm deciding between two architecture options: Microservices and Monolith. I've never used microservices before, but I have some ideas on how to implement it. Can you help me choose the best approach? 2. Deep Dive into Microservices If microservices are the better choice, can you explain how it would work for user information? If the first one (Microservice), could you elaborate on that in detail? For instance, should the user information be stored solely in the user table in the database, and if so, how do other services need to access it … -
Django caching causing blank screen on Brave browser
I have a new Django website and have just implemented the filesystem cache (django.core.cache.backends.filebased.FileBasedCache). This seems to work fine when I use a chrome browser to view the site, but when I use the Brave browser, it initially shows the site on the first GET of a url, but upon subsequent refreshes it draws a blank (white) screen. I am new to Django and, after reading the docs I think the following setting are all I need to implement it. And I can see the cache files being created on the server. So I assume I don't need to add the various decorators in the views (just want it to cache all pages). What is also interesting, is that the response time isn't that much quicker (from 550ms > 450ms).. maybe because its a filesystem cache?? Here are my settings CACHES = { "default": { "BACKEND": "django.core.cache.backends.filebased.FileBasedCache", "LOCATION": "/var/tmp/django_cache", "TIMEOUT": 600, } } MIDDLEWARE = [ 'django.middleware.cache.UpdateCacheMiddleware', 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'strip_whitespace.middlewares.HtmlStripWhiteSpaceMiddleware.html_strip_whitespace', 'django.middleware.cache.FetchFromCacheMiddleware', ] -

I've never used microservices before, but I have some ideas on how to implement it. Can you help me choose the best approach? Microservices: This breaks down the application into smaller, independent services (e.g., User Service, Schedule Service, Assignment Service). Each service has its own database and can be developed, deployed, and scaled independently. Monolith: This is a single, unified application where everything is bundled together. It's simpler to set up initially but can become cumbersome and slow as the application grows. 2. … -
Apps without migrations must not have relations to apps with migrations. Why?
There is a vague paragraph in django docs: Apps without migrations must not have relations (ForeignKey, ManyToManyField, etc.) to apps with migrations. Sometimes it may work, but it’s not supported. I have 5 years of experience and never encountered problems in these cases. In what case it's dangerous to have relation to "apps with migrations" ? -

How can both ECS services, using the same Docker image but running in different containers, share the same Docker volume?
I'm working on a Django application where I need to upload a file received from a Django admin form to an S3 bucket asynchronously using a Celery shared task. Here is the relevant code: Django Model: import os import uuid from django.db import models def generate_file_upload_path(instance: "MyModel", filename: str): _, ext = os.path.splitext(filename) randomised_hex = uuid.uuid4().hex # name format: meta_uuid-randomised_hex.mp4 return f"{instance.id}-{randomised_hex}{ext}" class MyModel(models.Model): media_file = models.FileField(upload_to=generate_file_upload_path, blank=True, null=True) thumbnail_file = models.FileField(upload_to=generate_file_upload_path, blank=True, null=True) Model Admin: from django.contrib import admin from .models import MyModel from .tasks import process_media_file class MyModelAdmin(admin.ModelAdmin): list_display = ["release_year", "created_by"] def save_model(self, request, obj, form, change): super(MyModelAdmin, self).save_model(request, obj, form, change) if obj.media_file and obj.thumbnail_file: process_media_file.delay( { "media_meta_id": str(obj.id), "operation": "upload", } ) admin.site.register(MyModel, MyModelAdmin) I tried several solutions to make this work: 1. Base64 Encoding: I saved the base64 encoded string of the media and thumbnail files in the media_url and thumbnail_url fields respectively. In the Celery task, I decoded these strings, created files, and then uploaded them to S3. This approach was slow for larger files. 2. Direct S3 Upload: I saved the file received from the form directly to the S3 bucket using models.FileField(upload_to="path-to-bucket-dir"). This improved the speed but was not an asynchronous … -
Failed to execute postMessage on DOMWindow: http://x.localhost:8000 does not match the recipient window's origin http://localhost:8000
I've looked at a bunch of similar posts here and couldn't find a solution that has helped with this issue. I have an iframe embedded in a domain I don't control. That iframe opens a popup window and I'm trying to communicate between them. Things like window.opener don't work because the browser clears window.opener in this scenario. I've been reading that postMessage is a good way to get this to work but I keep getting this error whenever I try. Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('http://x.localhost:8000') does not match the recipient window's origin ('http://localhost:8000'). (I am using a Django app w/ JS frontend) I've tried setting window.document.domain='localhost but I get the error: Uncaught DOMException: Failed to set the 'domain' property on 'Document': 'localhost' is a top-level domain. Is there some way for me to do this? TIA! -

javascript debug statements not showing up on console
So I am working on a Django mock website similar to restoplus, where restaurants can fill in their name, image, details, menus, sides, toppings, pick their brand colours (primary colours and secondary colours) and it will generate a standard landing page for that restaurant using the brand colours and details and menus. Now the problem is I am trying to update the price in real time using js depending on what the user selects. But it's not working. Also the quantity + - buttons are also not working. Now for that I have tried to use debug statements but even when I click on the buttons or select a menuitem option, neither the price gets updated not the quantity, and the console is clear, nothing appears on the console. Why is this? Can anyone help me out here? Thanks!

Can one inherit a ModelSerializer and Merge Models
I am trying to inherit djoser's UserCreatePasswordRetypeSerializer Djoser Modelserializer's model is User. The child Serializer that I am implementing represents a different model, Customer. So could one do: class CustomerSerializer(UserCreatePasswordRetypeSerializer): class Meta: model=Customer fields = ('customer_name',)+UserCreatePasswordRetypeSerializer.Meta.fields When I do this django is complaining because Customer model does not have the model fields that User has. this is the customer model but this model does exactly represent this model. class Customer(models.Model): customer_name = models.CharField(max_length=255) user = models.ForeignKey(User,on_delete=models.CASCADE,related_name='user') Would passing User as a parent class solve this issue? class Customer(User): customer_name = models.CharField(max_length=255) would this work with inherited ModelSerializers. As Djoser is an app I can not change the UserCreatePasswordRetypeSerializer to fit my needs. I can either inherit is or this is the second approach i was thinking. create something like, class CustomerSerializer(serializers.ModelSerializer): user=UserCreatePasswordRetypeSerializer class Meta: fields = ('customer_name','user') since this is a nested serializer I will have to write create method myself. the issue is how can I call the create of the UserCreatePasswordRetypeSerializer in the create method that I implement because I need to use the create method of UserCreatePasswordRetypeSerializer since it handles sending emails and all the other features in the serializer. So I can not basically just pop … -

Azure Deployment - Server Error (500). Environmental Variables Error?
my azure environmental variables OPENAI_API_KEY = os.getenv('OPENAI_API_KEY') This doesn't seem to be working for azure deployment? What other steps do I need to make to ensure my azure deployed website can access my openai api key? I have created a vector database driven website using django. I am able to run the webapp and perform searches using the api key on local host. I am able to do this while connected to the azure database. However, when I access my website through the public domain, I can't seem to perform searches. I've added the api key to the azure environmental variables already. It says Server Error 500 when I try to perform searches. Is there anything else I need to do? What could be causing server error 500? -
How do I reference the author name column from the Author table in my InsertBook function?
(https://i.sstatic.net/EiBqboZP.png) In the browser, I'm trying to add a new book to my books table but I keep receiving a Value error from django where for example I can't assign "'Virginia Woolf'": "Book.author" must be a "Author" instance. After I enter all the fields to add a new book and then click the Insert button in the browser, I receive the Value error. Below is the structure of my sql table as well as related python scripts for reference: --Create the books table CREATE TABLE books ( book_id SERIAL PRIMARY KEY, title VARCHAR(200) NOT NULL, author_id INTEGER REFERENCES authors(author_id), genre VARCHAR(50), price DECIMAL(10, 2), publisher VARCHAR(100), --Adding the column for the ISBN to populate the table with an extra instance isbn VARCHAR(20) ); --Create the videos table CREATE TABLE videos ( video_id SERIAL PRIMARY KEY, title VARCHAR(200) NOT NULL, genre VARCHAR(50), price DECIMAL(10, 2), publisher VARCHAR(100), release_date DATE ); views.py: from django.shortcuts import render from bookstore.models import Author, Book from django.contrib import messages from bookstore.forms import Authorforms, Bookforms def index(request): return render(request, 'index.html') def author(request): allauthor=Author.objects.all() return render(request, 'author_list.html', {'authors': allauthor}) def Insertauthor(request): if request.method=="POST": if request.POST.get('author_id') and request.POST.get('name') and request.POST.get('birthdate') and request.POST.get('nationality'): saverecord=Author() saverecord.author_id=request.POST.get('author_id') saverecord.name=request.POST.get('name') saverecord.birthdate=request.POST.get('birthdate') saverecord.nationality=request.POST.get('nationality') saverecord.save() messages.success(request,'author …
