Django Logging: ValueError: Unable to configure handler 'gunicorn'
I configured logging for a new Django project, and here is the code for my settings.py: LOGGING = { "version": 1, "disable_existing_loggers": False, "handlers": { "warnfile": { "level": "WARNING", "class": "logging.FileHandler", "filename": BASE_DIR / "warning.log", "maxBytes": 1024 * 1024 * 25, # 100 mb }, "errorfile": { "level": "ERROR", "class": "logging.FileHandler", "filename": BASE_DIR / "error.log", "maxBytes": 1024 * 1024 * 25, # 100 mb }, "gunicorn": { "level": "DEBUG", "class": "logging.handlers.RotatingFileHandler", "formatter": "verbose", "filename": BASE_DIR / "gunicorn.log", "maxBytes": 1024 * 1024 * 25, # 100 mb }, }, "loggers": { "": { # keeping it empty for all kinds of loggers "handlers": [ "warnfile", "errorfile", ], "level": "WARNING", "propagate": True, }, "gunicorn.errors": { "level": "DEBUG", "handlers": ["gunicorn"], "propagate": True, }, }, } Let me explain: I want to put 2 kinds of logs: warnings, and errors, in 2 differents files.

Django: How to create an tabular inline like the one in admin panel with "+ Add another"?
I currently rely on the admin panel to create or edit a new/existing order (i.e. Order with its children model OrderItem in the tabular inline). But this time I need to create a view with the same function for non-admin users. More specifically, I need the + Add another button in the tabular inline for users to add more Order Items themselves when necessary. I have looked into a few stackoverflows (one of them) and books. So far they at most only mentioned about inlineformset_factory, but not how to create the + Add another. Any ideas please? Thank you! -
How can I create an book index with Python?
I have a section, and in this section, I have topics, for example, book chapters. But, on this section page, I only have the last three chapters, so, when I click, I can move forward to the single page where I am. This is my HTML template. <ul> {% for chapter in book %} <li> <a href="#{{ chapter }}">{{ chapter }}</a> </li> {% endfor %} </ul> But, how can I access a section in example/book?page=2#chapter_five? I tried to create a function to find the chapter in a for loop with all the pages, but I got that the object was not iterable. I tried it in my views. chapter = chapters.object_list chapters_pages = paginator.num_pages for page in chapters_pages: if page.contains(chapter): context["chapter_page"] = page So I could do it, but it not worked. <ul> {% for chapter in book %} <li> <a href="?page=chapter_page#{{ chapter }}">{{ chapter }}</a> </li> {% endfor %} </ul> -

Is django's SCRIPT_NAME applied to STATIC_URL?
I'm serving django with gunicorn and nginx. And I've observed a strange behavior, which looks like django is prefixing MEDIA_URL with SCRIPT_NAME but it is not prefixing the STATIC_URL. Am I handling it properly? My static's configuration: STATIC_URL = "backend/static/" # this looks odd but works STATIC_ROOT = "/var/www/static" STATICFILES_DIRS = [BASE_DIR / "static"] MEDIA_URL = "media/" # this looks fine MEDIA_ROOT = "/var/www/media" gunicorn configuration: [Service] User=www-data Group=www-data Environment="DJANGO_SETTINGS_MODULE=backend.settings.production" WorkingDirectory=/var/www/backend ExecStart=/var/www/backend/venv/bin/gunicorn \ --access-logfile - \ --workers 3 \ --bind unix:/run/gunicorn.sock \ backend.wsgi:application nginx configuration: location ^~ /backend { proxy_set_header SCRIPT_NAME /backend; include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; location ^~ /backend/static { alias /var/www/static/; } location ^~ /backend/media { alias /var/www/media/; } } -
Django 'DetailView' object has no attribute '_meta'
This has floored me. I'm building a model with Django & REST API, and I'm having trouble rendering the DetailView for individual cars to the browser. The ListView works fine, but I'll include the code too since they are interlinked. In particular, I can't get the get_object() function to work properly. The first approach I tried used this approach: views.py class CarDetailView(generics.RetrieveUpdateDestroyAPIView): renderer_classes = [TemplateHTMLRenderer] template_name = 'car-detail.html' queryset = Car.objects.all() lookup_field = Car.id @action(detail=True, renderer_classes=[TemplateHTMLRenderer]) def get(self, request, *args, **kwargs): car = self.get_object() return Response({ 'car': car, }) While the page rendered properly with no errors, none of the template tags worked. Only {{ car.model }}, which returned None. So I changed the code to use a self.get_object() class CarDetailView(generics.GenericAPIView): renderer_classes = [TemplateHTMLRenderer] template_name = 'car-detail.html' queryset = Car.objects.all() lookup_field = Car.id def get(self, request, id): serializer_class = CarSerializer car = self.get_object() id = Car.id return Response({ 'car': car, }) but that raises the Error: "AttributeError at /rentals/car/43c9b98d-9f2d-473f-9c34-7b2e25630278 'CarDetailView' object has no attribute '_meta'" Can you help with this?
