Django's static file (.js) is not displayed on frontend
This is my folder structure in my react.js app. I have set NO router to display worker.js file on frontend. The file is just there with no further settings. And yet, since its in "public" folder, I can display it on my frontend like this My question is, how can I achieve same thing with Django? ***I tried different urls, different paths to see my file on my frontend but nothing worked ***... I also tried to set path/router for worker.js both in django and react side but then its rendered as html... I need it to be seen as js file. I need to achieve this because I'm using that react app's production folder in my Django app as template and need that worker.js file to be reachable in that same link you see in the image. My settings.py file: ... STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, "settledhead/build/static"), ] STATIC_ROOT = os.path.join(BASE_DIR, "settledhead/static_root") ... And this is how react's production folder looks like in my django app -

Django Test | How to pass a a dictionary containing a dictionary value through clients.post
I have a dictionary A that contains a single value that is also a dictionary B B = {"k1": "v1", "k2": "v2", "k3": "v3"} A = {"User": B} This type of dictionary is used in one of my views function def views_function(request): # request.data is a dictionary containing a single value that is also a dictionary. Just like A I'm trying to write a unit test for views_function from django.test.TestCase. from django.test import TestCase class test_cases(TestCase): def setUp(self): self.B = {"k1": "v1", "k2": "v2", "k3": "v3"} self.A = {"User": self.B} self.url = reverse("views_function_url") def test_views_function(self): response = self.client.post(url, self.A, format="json") But clients.post seems unable to take A as an input. When I print A inside test_views_function it shows the proper dictionary. def test_views_function(self): B = {"k1": "v1", "k2": "v2", "k3": "v3"} A = {"User": B} print(A) # {"User": {"k1": "v1", "k2": "v2", "k3": "v3"}} response = self.client.post(url, A, format="json") But when I add a print statement to views_function for some reason only the last key of B is there def views_function(request):{"User": "k3"} print(request.data.dict()) # {'User': 'k3'} -
How do i stop dark mode from flickering when page is refreshed

502 Bad Gateway (13 permission denied) Nginx + Gunicorn
I am trying to deploy a simple hello-world Django site to EC2 (Ubuntu 22.04) using Gunicorn and Nginx. Nginx and Gunicorn services are both reporting as running successfully, and the .sock file has been created seemingly without issue. Gunicorn configuration file: [Unit] Description=gunicorn daemon After=nextwork.target [Service] User=ubuntu Group=www-data WorkingDirectory=/home/ubuntu/sites/mysite-main ExecStart=/home/ubuntu/.local/share/virtualenvs/mysite-main-_EzVOJAm/bin/gunicorn --access-logfile - --workers 3 --bind unix:/home/ubuntu/sites/mysite-main/mysite-main.sock myapp.wsgi:application [Install] WantedBy=multi-user.target Nginx configuration: server { listen 80; server_name <domainname>.com <ipaddress>; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/ubuntu/sites/mysite-main; } location / { include proxy_params; proxy_pass http://unix:/home/ubuntu/sites/mysite-main/mysite-main.sock; } } Permissions on the .sock file, as well as both the "sites" and "mysite-main" directories are ubuntu:www-data. I attempted to try moving it out of the ubuntu user's home directory into a more "common" location in case it was permissions on the home directory stopping it, but was unable to even get the .sock file to generate in that case, probably due to my unfamliarity with how this works. It looks like this is one of the most queried problems of all time, but I've tried every solution I could find to no avail. Any help would be greatly appreciated. Thanks in advance! -

How can I use addEventListener to multiple buttons which are displayed with a for loop?
I have a page that displays social media posts from users and all posts have an Edit button. When the Edit button is clicked on, a form with a textarea pre-filled with the current content and a submit input is displayed. The problem is that regardless of which post's Edit button I click, always the first post is changing. I guess I should add an "id" somewhere to track which post is being edited but I couldn't figure out how to do that. Or is there another solution? views.py: def index(request): post_list = AllPost.objects.all().order_by("date").reverse() paginator = Paginator(post_list, 10) # Show 10 posts per page. page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) return render(request, "network/index.html", { "posts": post_list, "page_obj": page_obj }) def edit(request, id): if request.method == "POST": new_content = request.POST["new_content"] updated_post = AllPost.objects.filter(id = id) updated_post.update(content = new_content) return JsonResponse({}, status = 201) return JsonResponse({"error": "Bad Request"}, status = 400) index.html: {% for post in page_obj %} {{ post.full_name|upper }}<br> <div class="frame"> <h4><a href="{% url 'profile' post.user.username %}" style="color: black;">{{post.user.username}}</a></h4> {% if post.user == user %} <button class="btn btn-sm btn-outline-primary" id="edit">Edit</button> {% endif %} <div id="content">{{post.content}}</div> <form action="{% url 'edit' post.id %}" method="post" id="edit_post" style="display: none;"> {% csrf_token %} <div class="form-group"><textarea … -
When does using sqlite become a bottleneck?
I am currently working my way through the Udemy course Python Django - The Practical Guide by Academind, and during the deployment section the author mentions that one deployment consideration is the choice of database. He states that for larger sites with a larger volume of requests, using a sqlite database (the default when using Django) can become problematic and can slow down the site. However, he does not go on to explain this in a quantitative way. Is there some value, or perhaps a rule of thumb, by which you could draw a line between those sites for which a sqlite database is adequate, and those for which it is not? Thanks -

Sending html button status to django view
I am trying to create a button the picks orders from a list of paid products to a list of unpaid or Vice versa upon clicking the pick me button. But I don’t know how to go about this problem as Iam not well vested in using JavaScript. What I want is when a user clicks the pick me button on the list of unpaid orders, the order stops showing on the unpaid orders and starts to show on the paid orders and Vice versa or rather when the click the pick me button the order goes to the myorders list in there account. I tried just filtering with jinja templates and sending the value of the button as True on a condition model field that by default I made false then sending it as post form data to the view. But this just kept blowing up in my face as it did not work when the order will be made by someone else and picked by someone else -

How to block user authorization for Django Rest Framework in custom Middleware?
Hi I am creating a custom middleware in Django for the DRF. So that when an user try to access any of the api the middleware will perform some operation and determine if the user is authorized to access the endpoint or not. My code is like below: class PermissionMiddleware(MiddlewareMixin): def process_view(self, request, view_func, view_args, view_kwargs): if request.path.startswith('/admin/'): return None if request.path.startswith('/api/'): is_allowed = True if not is_allowed: return # < -- What needs to return to block the access return None My problem is what should I return from the method for disallowing access to api? I can return None, if I want to give access. But I want to disallow access and return some message from the api view so that user knows that he is not allwed. So in summery: What should I return from the middleware to block access? How can I return message to user from the view that he is not authorized? Thanks
