Using the URLconf defined in lecture3.urls, Django tried these URL patterns, in this order: admin/ The current path, hello/, didn’t match any of thes
I am new to using Django and following a tutorial (https://video.cs50.io/w8q0C-C1js4?screen=gytX_rSwZRQ&start=1160). So far this course has been great! However, now I am stuck at successfully creating a new app using Django. Here is the result of my efforts: Django page not found Here is what the result should be: Hello, World page when found tutorial As far as I know I've done everything correctly, perhaps I am missing something? Below is the code I am using, which results in Django returning the error in the title: urls.py lecture3: from django.contrib import admin from django.urls import include, path urlpatterns = [ path('admin/', admin.site.urls), path('hello/', include("hello.urls")) ] urls.py hello: from django.urls import path from . import views urlpatterns = [ path("", views.index, name="index") ] views.py: from django.http import HttpResponse from django.shortcuts import render # Create your views here. def index(request): return HttpResponse("Hello, World!") settings.py: INSTALLED_APPS = [ 'hello', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ] I am currently using: Python 3.9.4, and Django 3.2.3 Any and all help that can be provided will be greatly appreciated.

How to fetch object with multiple levels of reverse lookup
In my project, there are three models: class Level1(models.Model): name = models.CharField(max_length=250) class Level2(models.Model): name = models.CharField(max_length=250) level1 = models.ForeignKey(Level1, on_delete=models.RESTRICT) class Level3(models.Model): name = models.CharField(max_length=250) level2 = models.ForeignKey(Level2, on_delete=models.RESTRICT) Level1 model has 2 objects WA, TX. Level2 has 5 objects AAA, BBB where foreign key is WA and AAA, CCC, DDD where foreign key is TX. In Level3, I want to add a object RRRR where the Level2 foreign key object is AAA. When I tried to fetch the level2 by Level2.objects.get(name='AAA'), it shows error "get() returned more than one Level2 -- it returned 2!" How to solve this issue. Thanks in advance. -

Ordering the contents of a Django filter dropdown control
I have a Django filter, which works as expected allowing filtering of a List by selecting items in a dropdown control, but when it is rendered, the dropdown control items are in the order they were entered into the database, which is also to be expected. However, this is not user friendly as it's really difficult to find the desired item. I'm trying to figure out how to sort the list of items displayed in the dropdown control (composer) in alpha order. Any help would be appreciated as I'm a novice with all of this. The Filter code is below. I think I may need to manipulate a widget but not sure... class PieceFilter(django_filters.FilterSet): class Meta: model = Piece fields = ['composer', 'instrumentation'] exclude = ['title', 'description', 'study_notes', 'score_file', 'purchase_from', 'genre'] The filter renders two dropdown controls for filtering: 'composer' (which needs to be in alpha order) and 'instrumentation'. On the template, the following code renders a button to search on the chosen items from the dropdown controls. <form method="get"> {{myFilter.form}} <button class="btn btn-primary" type="submit">Search</button> </form> The view being used: def library(request): pieces = Piece.objects.all().order_by('composer__name', 'instrumentation') p = Paginator(pieces, 10) print('NUMBER OF PAGES') print(p.num_pages) page_num = request.GET.get('page', 1) try: page … -

Django + Postgres: saving PDF file with NUL (0x00) characters to DB and decoding it back to PDF
I have a pdf file that I want to save in my Postgres DB When I tried to save the file it brings A string literal cannot contain NUL (0x00) characters. so I followed the solution from here which replaces the null with a � character unicode(ppbData[0], errors='ignore').replace("\x00", "\uFFFD") The problem is that I can't convert it back to PDF now. I tried encode() and other methods file = open('new.pdf', 'wb') file.write(text.encode()) file.close() but it returns blank pdf Is there any way to replaces the � character with a null or any other way to convert it back to normal pdf? Maybe the first solution with replacing also wasn't right and there is another way? -
Django - NoReverseMatch Error (Views don't make any sense)
Django is the worst web framework I've ever used. def io_simulation(request): form = SimForm(request.POST) print('FIRST' + str(request.POST)) if form.is_valid(): form.save() print(form) return render(request, 'App/simulation.html', {'title': 'Simulation'}) This shows that my POST data is being sent correctly, but it's not reaching my database. FIRST<QueryDict: {'csrfmiddlewaretoken': ['dzowQoB3lk2IOOc19QXQDPZ3soJaxglaP76cURfjB6GMU3VBkHDe7IDhIp2CPpyK'], 'sim_concentration_range': ['3'], 'sim_concentration_range_2': ['4'], 'sim_concentration_range_unit': ['ppm']}> If I use io_simulation as the action for my form submission then I get a NoReverseMatch error that I don't understand, and I don't get my POST data printed out. If I use this completely nonsensical function as the action: def save_sim_data(request): print('SECOND'+str(request.POST)) if request.method == 'POST': request.POST.get('sim_concentration_range') request.POST.get('sim_concentration_range_2') request.POST.get('sim_concentration_range_unit') data=Sim() data.sim_concentration_range = request.POST.get('sim_concentration_range') data.sim_concentration_range_2 = request.POST.get('sim_concentration_range_2') data.sim_concentration_range_unit = request.POST.get('sim_concentration_range_unit') data.save() print('1') return render(request, 'nowhere.html') else: print('2') return render(request,'I/can/put/whatever I want here without any eRRerrors.html') Then I do see my POST data get printed (and it's correct (output in blockquote above)), but I still get nothing in my database. I cannot make any sense of Django debugging. What the hell is going on??? -
Why subclassing AppConfig is required in Django
From Django official docs, it reads: It is important to understand that a Django application is a set of code that interacts with various parts of the framework. There’s no such thing as an Application object. However, there’s a few places where Django needs to interact with installed applications, mainly for configuration and also for introspection. That’s why the application registry maintains metadata in an AppConfig instance for each installed application. Above means subclassing AppConfig is for maintaining metadata, which is used for configuration and also for introspection. Q1: Apart from labeling in Django Admin portal, I did not see any other use cases. any other examples for configuration and also for introspection ? Below posts did not help me out. What is the purpose of apps.py in Django 1.9? How is Django apps.py supposed to be used? -

How to set value of DateTime field automatically in Django REST Framework HTML form?
I have a very basic Django Model and use it in Django REST Framework. When using the browsable API tool and requesting an instance of a ressource, I can set the values of the different attributes using the HTML form at the bottom of the page.

Fargate oneoff task keeps running
I'm having an issue with a fargate one off task , it's meant to run database migration and then stop but it keeps stuck in running status this is the task definition : resource "aws_ecs_task_definition" "migrate" { family = "${var.project_name}-${var.environment}-migrate" network_mode = "awsvpc" requires_compatibilities = ["FARGATE"] cpu = 512 memory = 1024 execution_role_arn = aws_iam_role.ecs_task_execution_role.arn task_role_arn = aws_iam_role.ecs_task_execution_role.arn container_definitions = <<DEFINITION [ { "name": "${var.project_name}-migrate", "image": "${var.repository_url}:latest", "cpu": 512, "memory": 1024, "command": [ "/bin/sh", "-c", "python manage.py migrate --no-input" ], "mountPoints": [], "environment": [ { "name": "DJANGO_SETTINGS_MODULE", "value": "****" }, { "name": "DB_HOST", "value": "****" }, { "name": "DD_API_KEY", "value": "****" } ], "secrets": [ { "name": "SECRETS", "valueFrom": "*****" } ], "logConfiguration": { "logDriver": "awslogs", "options": { "awslogs-group": "****", "awslogs-region": "****", "awslogs-stream-prefix": "******" } }, "volumesFrom": [] } ] DEFINITION } and this is how i call it from github actions aws ecs run-task --launch-type FARGATE --cluster cs-name --task-definition $MIGRATE_TASK_ARN --network-configuration "awsvpcConfiguration={subnets=[${{ secrets.MIGRATE_TASK_SUBNET_IDA }}, ${{ secrets.MIGRATE_TASK_SUBNET_IDB }}],securityGroups=${{ secrets.MIGRATE_TASK_SECURITY_GROUP_ID }}}" any idea what's wrong ?
