Django images don't show up on the web-site
settings.py MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') template <img src="{{ group_avatar.avatar.url }}" style="width:30%" alt="Group Avatar" class="navbar-brand"> urls.py `urlpatterns = [ path('admin/', admin.site.urls), # Django admin route path("", include("apps.authentication.urls")), # Auth routes - login / register # ADD NEW Routes HERE # Leave `Home.Urls` as last the last line path("", include("apps.home.urls")) ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)` Instead of getting an image, I get an alt text... I've tried to fix it up for a long time, but nothing works... Django version 3.2.16, using settings 'core.settings' I suppose that the problem is in the project structure. It was done before I started working on the project and it would be difficult to change it... application is in the folder apps, which is in the root folder, and template which is needed is also there. But the folder 'media' is in the root directory. Although I'm not sure that the problem is in this. Interesting fact is that if I manually write the way to the image from static folder (static folder is also localed in apps directory) it will work. Would be glad for any help) Searching, reading documentation. I expect a hint how to fix it or where to search the … -
Django Paginator with bulk_update only updates odd pages
I have a two tables that have around 1M rows and in one of them, I've added a new migration that adds two new columns to one of them and that requires some computation to add their values. What I did was a command that fetches all rows in that table, and use Paginator with a chunk size of 1000, and after adding the new values, I perform the bulk_update. The problem is that only the odd pages are updated, the even ones stay with the null value. I start with 1000 pages to update, then I need to run again only to update 500 pages, and so on. I've also tested with chunks of 10, and the problem persists. Is there something wrong with this code? def add_values_to_columns(foo): foo.col1=... foo.col2=... class Command(BaseCommand): def handle(self, *args, **options): try: queryset = Foo.objects.all() \ .filter(col1__isnull=True, col2__isnull=True) \ .order_by("id") \ .select_related("bar") chunk_size = 1000 paginator = Paginator(queryset, chunk_size) pages = paginator.page_range number_pages = pages[-1] for page_number in pages: page = paginator.page(page_number) updated_rows = [] for foo in page.object_list: add_values_to_columns(foo) updated_rows.append(foo) Foo.objects.bulk_update(updated_rows, ["col1", "col2"]) except Exception as e: self.stdout.write(e) -

Can not configure postgres database in GitHub actions pipeline using Docker
I am creating pipeline for my Django Project with GitHub actions and can't make it working correctly. As I use docker, when I start the Docker and start my tests with 'python manage.py test' it works correctly. But when my tests are started I get an error. The reason is probably is that it does not know how to connect to DB, as Docker works with that in my case. I tried to use github secrets, but it seems that it does not work. Here is the traceback in GitHub Actions: Creating test database for alias 'default'... /opt/hostedtoolcache/Python/3.11.4/x64/lib/python3.11/site-packages/django/db/backends/postgresql/base.py:405: RuntimeWarning: Normally Django will use a connection to the 'postgres' database to avoid running initialization queries against the production database when it's not needed (for example, when running tests).

Semantic-ui multiple How about customizing the display?
I have created a multi-selection dropdown box, but I don't want it to increase by one every time I click on it. I envisioned that it would display no more than three values, and if it did, it would display "4 for 10 selection", is there anything I can do to make this happen? I have tried this method but it gives me an error. //Customize the text that is displayed after multiple selections onLabelCreate: function(value, text) { if ($('.ui.dropdown').dropdown('get value').length > 3) { return '4 of 6 selected'; } } -

toggle table row based on unchecked checkbox
Not super familiar with frontend, but I have 4 checkboxes I'm using to filter table data. Any number of them can be selected at once. What I want to accomplish: get all unchecked boxes if no boxes are checked pass (meaning don't hide any rows) if a box is checked, for any box that is NOT checked, exclude the row associated with that unchecked box This is for a Django app and the table row id is being generated via database query. The table will have max 100 rows. Per the query I'm executing, any table row will be either: id="audio", id="video", id="writing", id="games" HTML: <div> <input type="checkbox" value="music" id="music_filter"> <input type="checkbox" value="video" id="video_filter"> <input type="checkbox" value="writing" id="writing_filter"> <input type="checkbox" value="games" id="games_filter"> </div> <table class="table"> <thead> <tr> <th>Col 1</th> <th>Col 2</th> </tr> </thead> {% for i in query_set %} <tbody> <tr id="{{i.media_type}}"> <td>{{some data}}</td> <td>{{some other data}}</td> </tr> </tbody> I have jQuery loaded via CDN in the html file and trying this: JQUERY/JS: $(document).ready(function(){ $('#music_filter', '#video_filter', '#writing_filter', '#games_filter').on('click',function(){ var notChecked = $("input:checkbox:not(:checked)"); if (notChecked.length > 0) { for (let i = 0; i < notChecked.length; i++) { $('#i').toggle(); }; }; }); }); A little help to see my mistake(s)? Thanks! -

How to change related object when creating object in DRF
I want to change is_available field in Book object when reservation is being create. I found a way which I am pasting here, but this digging in request looks messy, so as it often is with so mature frameworks as drf there are probably better ways to do that.

How can I assert that a pdf file was returned in python?

Specifically, this: status.HTTP_200_OK, 'application/pdf' I've seen a lot of posts about reading or opening files, but I just need to make sure it was in fact a pdf (file) that was returned. How can I set my mock up so that I can assert a pdf (file) was returned? -
How to attach HTMX parameters to a django input form
I am trying to implement an HTMX autosearch function to an input created by a django form. When I inspect the element on the page, the htmx tags are all present. However, the htmx never intializes and it never goes to the views endpoint. The code for the django input form is as follows: widget_attrs_nha_autosearch = { 'class': 'form-control', 'data-user-entry': 1, 'disabled': value.get('read_only'), 'hx-post': "{% url 'ng_django_pmp:nha-autosearch' %}", 'hx-target': '#results', 'hx-trigger': "keyup changed delay:500ms" } if value.get('label') == 'nha_override': self.fields[field] = forms.CharField( initial=value.get('default', ''), label=value.get('label'), max_length=value.get('max_length'), required=required, widget=forms.TextInput(attrs=widget_attrs_nha_autosearch), validators=value.get('validators', [])) When I attempt to create the htmx code on its own in html, it works just fine. However, I need the code to be created in this manner in order to properly trigger something on the backend. The HTMX code on its own is as follows: {% csrf_token %} <div class="d-flex justify-content-end mb-4"> <input type="input" hx-post="{% url 'ng_django_pmp:nha-autosearch' %}" hx-target='#results' hx-trigger="keyup changed delay:500ms" name="search" class="d-flex flex-grow-1 flex-column p-3 border border-secondary rounded m-2" style="overflow: auto; min-width: 0; min-height: 0" placeholder="" id='id_nha_override' /> </div> <div id="results"></div> Am I missing something? -

I added channels core and notification to installed apps INSTALLED_APPS = [ "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", "channels", "core", "notification", ] Added asgi configuration ASGI_APPLICATION = "reviewproject.asgi.application" Configured channel layers CHANNEL_LAYERS = { 'default': { 'BACKEND': 'channels.layers.InMemoryChannelLayer', }, } Here is asgi.py import os from channels.auth import AuthMiddlewareStack from channels.routing import ProtocolTypeRouter, URLRouter from django.core.asgi import get_asgi_application import notification.routing os.environ.setdefault("DJANGO_SETTINGS_MODULE", "reviewproject.settings") application = ProtocolTypeRouter( { "http": get_asgi_application(), 'websocket': AuthMiddlewareStack( URLRouter( notification.routing.websocket_urlpattern ) ) } ) I also have routing.py from django.urls import re_path from . import consumers websocket_urlpattern = [ re_path(r'ws/notification/$', consumers.NotificationConsumer.as_asgi()), ] consumer.py import json from channels.generic.websocket import AsyncWebsocketConsumer class NotificationConsumer(AsyncWebsocketConsumer): async def connect(self): self.group_name = "notification" await self.channel_layer.group_add(self.group_name, self.channel_name) await self.accept() async def disconnect(self): await self.channel_layer.group_discard(self.group_name, self.channel_name) async def send_message(self, event): message = event['message'] await self.send(text_data=json.dumps({'message': message})) And sending notification when Review is created class ProductView(View): def send_notification(self, message): channel_layer = get_channel_layer() async_to_sync(channel_layer.group_send)("notification", {"type": "send_message", "message": message}) def get(self, request, pk): reviews = ReviewModel.objects.filter(product=pk) product = get_object_or_404(ProductModel, pk=pk) context = { "reviews": reviews, "product": product } return render(request, …
