I'm trying to integrate Django with htmx. I want to render a form inside a table. but when I enter some data and submit it says the form is not bound. This is the view: def hx_payment_item_create(request, payment_id): payment = get_object_or_404(Payment, pk=payment_id) form = forms.PaymentItemCreateFromPaymentForm(request.POST or None) if request.method == "POST": if form.is_valid(): item = form.save(commit=False) item.payment = payment item.save() if request.htmx: return redirect("core:hx-payment-item-detail", pk=item.pk) return redirect("core:payment-item-detail", pk=item.pk) else: print(form.errors) context = {"form": form, "payment": payment} return render(request, "core/partials/payment_item_form.html", context) This is the template that will be rendered inside the table: <tr hx-target="this" hx-swap="outerHTML"> <form method="POST"> {% csrf_token %} {{ form.non_field_errors }} {% for hidden_field in form.hidden_fields %} {{ hidden_field.errors }} {{ hidden_field }} {% endfor %} {% for field in form.visible_fields %} <td> <label for="{{ form.subject.id_for_label }}">{{ field.label }}</label> {{ field.errors }} {{ field }} {{ field.help_text }} </td> {% endfor %} <td> <button type="submit" hx-post="#some_url"> submit </button> </td> <td> <button hx-get="#another_url" type="button"> cancel </button> </td> </form> </tr> -

Favicon and manifest.json is not loading in Django / React Project Setup
I already have seen possible scenarios to solve this problem with the help of this already posted question and answer. how-to-add-favicon-to-django-app-with-react-front-end? But I'm unable to reproduce the solution. Now the Problem is Favicon is generated automatically with a command: npm run build In the build dir which the Django is serving. This is how the build dir is generated after npm run build command and the build is generated from this public folder index.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <link rel="icon" href="%PUBLIC_URL%/favicon.ico" /> <meta name="viewport" content="width=device-width, initial-scale=1" /> <meta name="theme-color" content="#000000" /> <meta name="description" content="Web site created using create-react-app" /> <link rel="apple-touch-icon" href="%PUBLIC_URL%/logo192.png" /> <!-- manifest.json provides metadata used when your web app is installed on a user's mobile device or desktop.

CS50W: Project2 (Commerce) / Django
I am finishing a Django app on auctions. I am required to make a view for each listing showing the current bids on this listing, the details, and a form to be able to place a bid on the listing. I am having one minor issue in updating the listing price when a higher bid is placed by a user. The problem is in the logic of the listing_view function, but I can't spot it: def listing_view(request, listing): this_listing = Listing.objects.get(listing_name=listing) bid_count = this_listing.bids.count() if request.method == "POST": form = BidForm(request.POST) current_user = request.user if form.is_valid(): newest_bid = form.cleaned_data["bid_price"] if newest_bid >= this_listing.current_price: new_bid = Bid(listing=this_listing, bid_price=newest_bid, owner=current_user) new_bid.save() bid_count += 1 this_listing.current_price = newest_bid this_listing.bids.add(new_bid) return HttpResponseRedirect(reverse("auctions:listing_view", kwargs= {'listing':this_listing.listing_name})) else: return HttpResponse("Error") else: return render(request, "auctions/listing.html", { "listing": this_listing, "form": BidForm, "count": bid_count }) If you want the model definition of Listing and Bid, I can provide them, but I believe the issue is in the listing_view logic. -
Django REST Framework: how to make the index route browsable if routes are prefixed?
I've no use for the index route api.domain.tld/. Instead my routes start quite nested: api.domain.tld/v1/some/thing/ api.domain.tld/v1/foo/bar/ When I visit api.domain.tld/ I get a 404 - which makes sense, but I'd like to get browsable suggestions of the nested routes instead. Relevant code: router = routers.DefaultRouter() router.register(r'some', ThingViewSet) router.register(r'foo', BarViewSet) urlpatterns = # path('', '...') - is not in use path('v1/', include(router.urls)) ] Any idea? Thanks in advance! -

SimpleJWT cannot authorize after changing the SECRET_KEY in django

I have a project where I use Django with celery and I noticed when a task has errors I always have that message : Task celery succeeded in 0.09006300568580627s: None So I understand the task is finished but sometimes there are errors and I have succeeded which is for me not true.

How to retry a task if it's the last retry in celery?
I'm writing a send_mail task, which, if another instance of it is running, has to retry after 2 seconds. The number of retries is limited by 300. If there is a running instance and the last retry is currently running - the function has to send the mail, regardless of the other instance is running. If it fails - asynchronous recording to the log. How to implement the following with Celery? -
Nginx fastcgi_cache_path file naming / design / best practice
I'm trying to configure Nginx as a reverse proxy "properly". So many documentation, so many website advising bad practices... well I've come up with this: the folder conf.d was created by Nginx to include once all files in it. That's where I've made global_custom.conf In conf.d/global_custom.conf I define all the "cache" type that might be used like this: fastcgi_cache_path /var/run/nginx-cache-wordpress levels=1:2 keys_zone=WORDPRESS:50m max_size=10g inactive=60m use_temp_path=off; fastcgi_cache_path /var/run/nginx-cache-django levels=1:2 keys_zone=DJANGO:50m max_size=10g inactive=60m use_temp_path=off; fastcgi_cache_key "$scheme$request_method$host$request_uri"; fastcgi_cache_use_stale error timeout invalid_header http_500; I did nginx-cache with multiple aliases and multiple files like I do /var/run/nginx-cache-wordpress, /var/run/nginx-cache-django and then use them like this: server { server_name django.myserver.com fastcgi_cache DJANGO; # blabla } server { server_name wordpress.myserver.com fastcgi_cache WORDPRESS; # blabla } Is it a good practice, if not, how should I do? I can't find any valuable information for a good sample for a good nginx reverse proxy configuration. -
