What I am missing in the setup of nginx with gunicorn which leads to 502 error?
I am setting up django + gunicorn + nginx on my local (mac os) to test some nginx reverse proxy configuration. I have gone through few tutorials about the setup of these. I have a doubt: Everywhere in tutorials they run gunicorn as daemon or service. Why is it necessary? cant we just run gunicorn in a shell binding it to a port (which will be listened by nginx) My gunicorn.conf.py file: import os bind = '0.0.0.0:8080' errorlog = '-' worker_class = 'gthread' workers = 2 threads = 3 timeout = 60 max_requests = 25 max_requests_jitter = 3 preload_app = True worker_connections = 5 keepalive = 65 running gunicorn using : gunicorn --conf gunicorn.conf.py my-project.wsgi:application nginx nginx.conf: upstream test { server localhost:8080; keepalive 32; keepalive_timeout 65s; } server { listen 80; proxy_http_version 1.1; proxy_connect_timeout 5s; proxy_send_timeout 10s; proxy_read_timeout 20s; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; location / { proxy_pass http://test; } } then I run this nginx conf using nginx docker creating image from DockerFile: FROM nginx:alpine COPY nginx.conf /etc/nginx/conf.d/default.conf Then running the image by: docker run --rm -p 3030:80 --name test-server <image-name> after these localhost:8080 serves my django project through unicorn but localhost:3030 (nginx … -

How do I capture the state of an object in Django?
I have developed a web app in Django to record sales in a retail store. I have the following two models in my project: class Product(models.Model): code = models.CharField(max_length=256) name = models.CharField(max_length=256) description = models.CharField(max_length=2048) cost_price = models.DecimalField(max_digits=8, decimal_places=2) retail_price = models.DecimalField(max_digits=8, decimal_places=2) class Sale(models.Model): date = models.DateTimeField(default=timezone.now) product = models.ForeignKey(Product, on_delete=models.CASCADE) The problem I'm having is that when I edit the price on the product, it will also affect past sales of that product. This is because the product is a foreign key on the sale model. What is the best method to ensure that all sales are not affected by any edits on the product? I thought about adding a price field on the sale model to ensure that the price remains static, like so: class Sale(models.Model): date = models.DateTimeField(default=timezone.now) product = models.ForeignKey(Product, on_delete=models.CASCADE) price = models.DecimalField(max_digits=8, decimal_places=2) However, I'm not sure if this is the best solution, it seems hard coded in a way. I would appreciate any advice. -

I have my Django-app and I am using fileSystemStorage to store my media files and now I want to deploy my app on heroku. But the problem is that my code for media file storage is as follows: urls.py if settings.DEBUG: urlpatterns + static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT) settings.py . . # Upload Media Files MEDIA_URL = '/uploads/' MEDIA_ROOT = os.path.join(BASE_DIR, 'uploads') . . And in production mode we have to set "DEBUG to FALSE" which will produce a problem for storing the files. Can you suggest some ways to deal with this issue? Ps: I know that FileSystemStorage shouldn't be used in production environment but it's fine for my case since I'm using it to store files temporarily. -
how to not redirect to other page after JsonResponse in django?
I have 2 views which are post_detail_view and login_function. I use post_detail_view to render login form and login_function to handle POST request. # views.py def tutorial_detail_view(request, pk): context = {} context['object'] = TutorialPost.objects.get(id = pk) context['login_form'] = LoginForm() return render(request, "tutorial/tutorial_detail.html", context) def login_function(request): if request.method == "POST": login_form = LoginForm(request.POST) if login_form.is_valid(): email = request.POST['email'] password = request.POST['password'] user = authenticate(email = email, password = password) if user is not None: login(request, user) return JsonResponse({'success': True}, status=200) else: return JsonResponse({'form_errors': login_form.errors}, status=400) return JsonResponse({}, status=400) # urls.py path('post/<slug:pk>/', tutorial_detail_view, name="tutorial_detial"), path('login/', login_function, name="login") # tutorial_detail.html <form action="{% url 'login' %}" method="POST"> {% csrf_token %} {{ login_form.email }} {{ login_form.password }} <button type="submit">log in</button> </form> What I want is to get response or error response from JsonReponse and stay in tutorail_detail.html and post/<slug:pk> url and I have some javascript code to get that response but it keeps redirecting me to login url and display response there. How can i fix it? -
