Heroku can't find styles.css
Trying to deploy a Django app to Heroku for the first time. When I view the app using Django, everything shows up correctly, but when I run it on Heroku, pieces of the UI are missing. I'm not too familiar with the frontend - this was a group project and I was working on backend - and my team isn't willing to help with deployment, so I'm unable to diagnose any frontend issues. Looking at the Heroku logs, I get this error "Not Found: /static/styles.css" - but there is a styles.css file under static. Does anyone know where the root problem might lie? Under settings.py I have specified this STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATICFILES_DIRS = [os.path.join(BASE_DIR, 'staticfiles')] All functionalities work as expected, I think it has something to do with the base.html file - but this is just a stab in the dark. An example of what it's meant to look like, compared to what it looks like on Heroku. -
Django path not matching with urlpatterns in urls.py
Guys I am not a web developer, I have been learning django for a couple of hours now for my father's small business website and I am hitting a silly error for hours now. the name of the project is mysite and mysite urls.py looks like this from django.contrib import admin from django.urls import include, path urlpatterns = [ path("", include("index.urls")), path("about/", include("about_page.urls")), path("polls/", include("polls.urls")), path("admin/", admin.site.urls), ] mysite's settings.py also includes the correct AppConfig for the app. about_page included. INSTALLED_APPS = [ 'polls.apps.PollsConfig', 'index.apps.IndexConfig', 'about_page.apps.AboutPageConfig', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ] about_page's views.py is attached_below from django.shortcuts import render from django.http import HttpResponse from django.template import loader from django.http import Http404 # Create your views here. # return HttpResponse("website under construction !!!") def about_func(request): template = loader.get_template("about/about_page.html") context = { "about":"about_us", } return HttpResponse(template.render(context, request)) about_page's urls.py: from django.urls import path from . import views urlpatterns = [ path("about/", views.about_func, name="about_page"), ] polls and index apps have exact same pattern, i simply don't know why i cannot display about page. -
deploy project on my local machine with Apache
I built a website with Django, installed Apache and made all the adjustments. In addition, I bought a domain from GoDaddy for the site. I want to deploy the site on my computer.

What would be a better solution for storing data in a Django model?
Could you please give me a piece of advice? Context: I have a Django project in which each user stores many different variables linked to his profile. I created a model called Snapshot, that has a foreign key of user. Single user can have multiple Snapshots linked to his User instance, but only the latest one (by its ID, pk) is editable. Any other ones might be used to revert to past setup only. Typical use case: User modifies his setup stored in his latest Snapshot using API endpoints. Each function that an endpoint call has to query the latest Snapshot owned by user that called the function. Then it modifies some of the variables in the Snapshot and saves it. Once everything's done user approves the setup and the Snapshot is being duplicated. Now the new instance becomes the latest. Question: Is it a good idea to query the latest Snapshot this many times in each function? Wouldn't it be a good idea to link the latest Snapshot one-to-one with User, so that it's always available as User.latest_snapshot? This latest_snapshot would be automatically re-linked to User once user approves setup, thus creating a new Snapshot. -

Django: Make variable of child model depend on number of siblings associated with the same parent model
Assume I have two models, one modelling a Patient and another one modelling a tissue sample. To avoid confusing among lab members, instead of refering to the samples and the patients by a PK we transform the PK into a hashed string named displyed_id below. In the ideal case we would have a patient referred to as 'H6F4A' and the samples to be 'H6F4A-1', 'H6F4A-2', etc. (be labelled by a suffix of the sample number belonging to that patient). As a requirement we would need that if a sample is deleted that the sample numbering doesn't change for the suceeding samples (as the samples have physical barcodes printed onto them). As this is kind of hard to do (probably one would need a counter for every patient counting how many samples there are) we have opted to use the tissuesample pk as the suffix which is not really what we want as this is global and not per patient. Even if this new counter would not be a pk, combined with the hashed id of its parent e.g. sample 1 of patient 1 being 'H6F4A-1' it would need to be an injective mapping as staff will always refer to this … -

Using field in Trunc's kind property

Possible security risks for the following form submission in Django
I am trying to create the page for a livetime chat app using Django and some Ajax. I have always used django forms, since it is more secure and clean if you are not very familiar with javascript. The below html and views.py don't use django forms, but instead go with the traditional method of using javascript. However, I am concerned that there might be security leaks with this following form, which I copied from another website.

How to get full history executed function inside parrent function in Python / Django
I have function like this def test_func_1(angka): angka = angka + 3 result = test_func_2(angka) return result def test_func_2(angka): angka = angka + 5 return test_func_3(angka) def test_func_3(angka): angka = angka * 2 return angka def wrapper_func(): return test_func_1(3) When I call wrapper_func() I want to have history function that executed like this : wrapper_func() test_func_1(3) test_func_2(angka) test_func_3(angka) is that possible ? I know it's possible if we put trace_back.print_stack() like this Getting a python traceback without an exception But what if I don't have access to change that code ? It's very useful when I run django shell in the production server, and debug intermittent issue. So I can just call that function and I input specific parameter, then I can know what actually that function did -
Django session id cookie not as expected when requesting from swift
When I use Postman to log a user in I get my csrftoken and sessionid cookies in the response as expected. When I make the same exact request but on my iOS app on the simulator, I get the csrftoken cookie from my response just fine as expected. But I do not get the same sessionid cookie. The cookie I'm getting is named "__cf_bm" with a much longer than expected value. The domain of the sessionid cookie on iOS is also now "cloudflare-ipfs.com", whereas on both Postman and iOS the csrftoken domain is just 127.0.0.1. On Postman the sessionid cookie's domain is also just local host. I never did anything with cloudflare. What could be causing this? -
asgi config in Django
I implemented a chat environment with Django chat channel and it works with asgi, messages are exchanged on my computer without any problem, but when I upload my project on host, it does not exchange messages, I am wondering should I config my passenger_wsgi or some configuration from my host? My asgi config: import os import chat.routing from channels.auth import AuthMiddlewareStack from channels.routing import ProtocolTypeRouter, URLRouter from channels.security.websocket import AllowedHostsOriginValidator from django.core.asgi import get_asgi_application from chat.routing import websocket_urlpatterns os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings") django_asgi_app = get_asgi_application() application = ProtocolTypeRouter( { "http": django_asgi_app, "websocket": AllowedHostsOriginValidator( AuthMiddlewareStack(URLRouter(websocket_urlpatterns)) ), } ) My wsgi import os from django.core.wsgi import get_wsgi_application from django.core.asgi import get_asgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'zgalaxy.settings') aplication = get_wsgi_application() ` My passenger_wsgi from zgalaxy.asgi import application ` My settings.py ASGI_APPLICATION = 'zgalaxy.asgi.application' `
