How to get url for htmx get from an SSE event which itself triggers the hx-get call?
I am using django with django-channels and htmx. In certain cases, my django views will send an SSE event to a user subscribed to the relevant channel, like a notification for example. Some of those events (depending on event name) needs to trigger a modal pop-up (like a rating modal after an e-commerce order or service completes). I have implemented the requirements of the server-side event and data generation. I want to use the htmx sse extension on the frontend (django template). My problem is, I want to get an event, let's say order_complete, and use that to trigger an hx-get call to a particular url which will be sent by the sse event. That hx-get's response will then be placed in the placeholder where modal view logic exists. I have very little knowledge of JavaScript and not all that much more on htmx. I've looked at out of band swaps but I'm not sure if that's what I need. I'd appreciate any opinion or suggestions for proceeding including a non-htmx solution if it's better performing or easier. Thank you. -

Django Admin Custom Queryset. prevent e=1
I have a need to enter product ids in the url of my admin page but Django does not allow me to. This is my function that does work. def get_queryset(self, request): qs = super(LaptopStockAdmin, self).get_queryset(request) pid = request.GET.get('pid') if pid is not None: ids = [int(id) for id in pid.split(',')] return qs.filter(id__in=ids) else: return qs It gets the objects related to the ids but then Django refreshes the page and ads ?e=1 after the URL. This is a security related problem and I cannot find a suitable solution. I have tried these methods but they don't work for my specific case. Is there a way to not create a list filter and where the results are shown in the admin page? -

Nginx responds 404 not found on Django media URL in preprod, dev ok
I have a quite standard Django application with a Vuejs frontend. I have different environments (preprod/dev) in which I have file upload/download features. For files, everything works fine because they are returned through standard API views in attachment (Content-Disposition: attachment). When it comes to images though, like profile pictures, there is a problem. In development (DEBUG=True), I have this : from django.conf import settings from django.conf.urls.static import static from django.urls import include, path from backend.applications.base.views.authentication_views import LoginAPIView, LogoutAPIView urlpatterns = [ path("api/login", LoginAPIView.as_view()), path("api/logout", LogoutAPIView.as_view()), path("api/base/", include("backend.applications.base.urls")), path("api/contact/", include("backend.applications.contact.urls")), path("api/helpdesk/", include("backend.applications.helpdesk.urls")), path("api/inventory/", include("backend.applications.inventory.urls")), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) # For serving media files when DEBUG=True and images are correctly served (no nginx in dev mode, just frontend and backend dev servers). My preprod however, is made of a nginx container which serves my built vuejs frontend, and a backend container which contains my Django (DEBUG=False) application. Before trying to serve images, I had this nginx configuration : http { client_max_body_size 5M; upstream backend_api { server backend:8000; # 'backend' is the name of the backend service in my docker-compose config } server { listen 80; include /etc/nginx/mime.types; root /usr/share/nginx/html; index index.html; location = /favicon.ico { access_log off; log_not_found off; } location /api … -
Can't access Heroku /tmp/build_{sha} build files in Github Action once build has completed
I run a Github Action that deploys my app to Heroku with two relevant steps. Build Step: push to Heroku, build (including heroku/nodejs buildpack), create JS sourcemaps (among other things). Sentry Release Step: create a Sentry release, and ideally upload the sourcemaps created in Build Step. I've noticed in build logs that my build directory is /tmp/build_{sha}/. The project is built here, and sourcemaps therefore would be found in /tmp/build_{sha}/static/dist. The problem is, I can't find the build directory or the sourcemaps in Sentry Release Step, or any step that runs after Build Step has completed. Following Build Step completion, I've examined /tmp but there's no build_{sha} folder inside. Yet when I run heroku run bash on the deployed dyno, I see sourcemaps in /static/dist and /staticfiles/dist, where I'd expect them. So where did build files go after Build Step and before deployment? Shouldn't build files be accessible throughout the Github Action? I've had success accessing sourcemaps within Build Step, by using a Sentry Sourcemap buildpack. Obviously this runs during the build. But I would prefer to have this happen in the Github Action. I've also tried the SentryWebpackPlugin but I've determined sourcemaps must be uploaded once webpack has completed … -

Multi-User & parallel & Dynamic workflow in Django
I'm looking for the best solution for the development of workflow engine in Django (Django-Rest-Framework) by this requirement : permission checking/task assignment options Parallel workflows allow to have several active tasks at once and probably have some sort of parallel sync/join functionality dynamic workflows typically could be configuring by changing the contents of workflow database tables The approach I found: one approach is BPMN engines, and use the SpiffWorkflow package(which is python pure not Django) one other approach is to use camunda API (can create limitations) or use Django-based workflows packages that I did not find a package that supports Multi-user(permission) & Parallel & Dynamic workflows What is the best solution for this problem? -

datetimepicker format is not working properly
I used datetimepicker to select month and year. On the first click of the page load ,datetimepicker shows months and year.But when I click on the same date field again to change the month, datetimepicker displays dates instead of months. Here I also used select2 in my code.I implemented it in Django web framework. <script> $(function(){ $('#id_from_date').datetimepicker({ format: 'MM-YYYY', }); $('#id_to_date').datetimepicker({ format: 'MM-YYYY', }); }); $(document).ready(function() { $('select').select2(); }); Can anyone suggest a solution to solve this issue? -

Django Enum not reflecting @override_settings()
from django.conf import settings from django.test import TestCase class Enum1(Enum): X = f'{settings.X}' @override_settings(X='abc') class Test1(TestCase): def test1(self): self.assertEqual(settings.X, Enum1.X.value) # Doesnt work I have variable X in settings.py I modify it in this test case to X='abc' But the Enum is still using its old value. Is there a way to make Enum use new value ? One workaround is if I create a func in Enum1 then it works. eg: class Enum1(Enum): @classmethod def get_x(cls): return f'{settings.X}' The overall takeaway is that any class variable doesnt reflect override_settings() changes. Only a function which is not instantiated initially when py file gets imported, reflects those changes. -

Can't reset index in view function
I am calling a view function and that view function calls another function on a 1 min timer. The issue I am having is resetting the 'i' value. Can someone help me figure out how to fix this or or come up with a new way for me to do this. I want to call the getABC function on a one minute timer and have it loop through the 'listOfStrings' and then have it start the list back over once it reaches the end. I have a feeling I am looking over something and making it much more complicated than it needs to be. def viewfunction(request): listOfStrings = [...list Of Strings ] i = 0 def func(): for each in range(i-60, i-1): getABC(listOfStrings[each], each) if listOfStrings[each] == 'ZYXI': i = 0 return schedule.every(1).minutes.do(lambda: func()) while True: i += 1 schedule.run_pending() time.sleep(1) The issue with the code above is the 'i' in "for each in range(i-60, i-1):" gets the UnboundLocalError: local variable 'i' referenced before assignment.

Why is django losing session after save any python file?
I'm really stuck in my project, I explain: Every time I save a file, (no matter what it is) with a .py extension, I know that Django uses StatReloader to check for changed files. My problem is that it removes the logged in user (I don't know if it's a problem with the session) This has consequences for me, such as not being able to save and test things quickly, since I have to log in every time I save a file. It would be very helpful if someone can give me a hand! -
