Is there a way to redirect a non-www subdirectory to that subdirectory with the www domain?
I'm new to web hosting and I'm currently having trouble redirecting subdirectories that don't have the www subdomain. Typing example.com/subdirectory/ just goes to https://www.example.com/ I want it to go to from example.com/subdirectory/ to https://www.example.com/subdirectory/ I'm using django, pythonanywhere, and namecheap. I've already looked a lot online but there just doesn't seem to be any examples with someone using django, pythonanywhere and namecheap. There were some cases where using htaccess solved the problem, but I don't think it's compatible with django? -

Papertrail logs not displaying for Django app in production
I have a Django app that is deployed to production using Heroku. I am currently trying to integrate papertrail logging but no logs are being sent to production. At this point I am at a total loss as to why my logs are not going through. I am not using papertrail as a Heroku addon, but am using the web interface. This is what my LOGGING setting is in settings.py LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'verbose': { 'format': '{levelname} {asctime} {module} {message}', 'style': '{', }, }, 'handlers': { 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', 'formatter': 'verbose', }, 'papertrail': { 'level': 'INFO', 'class': 'logging.handlers.SysLogHandler', 'address': ('logsX.papertrailapp.com', XXXXX), 'formatter': 'verbose', }, }, 'loggers': { '': { # This is the root logger, capturing logs from any logger. 'handlers': ['console', 'papertrail'], # Start with 'console' for development. Add 'papertrail' for production. 'level': 'DEBUG', 'propagate': True, }, }, } NOTE: In my code the address is correct, I am of course redacting it in this post. In my views.py I have the following code: import logging logger = logging.getLogger(__name__) def index(request): logger.warning('test') I have deployed this to production but I see no logs coming in.

How to display data from api json for django
I'm trying to create a weather website in django but I don't know exactly how to get apis data and display it in my templates. following a tutorial I arrived at this view: from django.http import HttpResponse import requests def weatherdata(request): response = requests.get('https://api.open-meteo.com/v1/forecast?latitude=52.52&longitude=13.41&hourly=temperature_2m,relative_humidity_2m,precipitation').json() context = {'response':response} return render(request,'home.html',context) and this html: <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <strong>LATITUDE AND LONGITUDE</strong> {{latitude}} {{longitude}} </body> </html> considering the following lines in the api: {"latitude":52.52,"longitude":13.419998, and the result was, basically nothing.

How to save logs, to S3Boto3Storage, with Django Logging

How do i use external file storage for user uploaded files in Django

Encountering Server Error (500) During Website Deployment Without Clear Error Messages On Render.com

Troubleshooting Plesk: Resolving Python Django App Issues
I recently encountered a frustrating issue while attempting to deploy my Python Django 3 application on a hosting server running Plesk on CentOS. Every time I tried to access the application URL, I was greeted with a discouraging 403 error. Despite my efforts to tweak various Apache, nginx, and HTTPS directives within Plesk, as well as experimenting with Passenger, none of my attempts seemed to resolve the issue. Has anyone else faced a similar challenge, and if so, how did you manage to overcome it? I'm eager to hear any suggestions or insights that could help me get my Django app up and running smoothly. Thanks in advance for any assistance! -

Dump Web Client Sending the same post request MANY times to Django server
I am developing an acquisition server for an IoT application, I am using Django web framework for this task. (Acquisition server is a server that recieves messages from a client "a hardware Microcontroller in my case" and saves the data it recieves to the database) The client I am working with is a closed source controller, so I cannot modify how it behaves. I only have control over my acquisition server. The problem: The controller is sending the same request with the same data multiple times in a row and django is opening a new thread for every request. I want Django to handle the request of the controller and not open a new thread for the controller (the controller is dump), after Django handles the request it sends a confirmation messages to the controller and the controller would send next request. How can I achieve that in Django? I do not know where to start or how to look for an answer for my question. -

Connect flutter app to django using websockets
I'm completely new to WebSockets, so basically I'm trying my best to create in my Django project and integrate it in my Flutter project. The idea is to have a rooms and the participants of those rooms to be able to chat. So, in my Django settings, I have added 'daphne' in the installed apps, I have created my chat consumers like so: class ChatConsumer(AsyncWebsocketConsumer): async def connect(self): # scope is the request parameters passed from the url route self.room_id = self.scope['url_route']['kwargs']['room_id'] self.room_group_name = 'chat_%s' % self.room_id # Join room group await self.channel_layer.group_add(self.room_group_name, self.channel_name) await self.accept() async def disconnect(self, close_code): # Leave room await self.channel_layer.group_discard(self.room_group_name, self.channel_name) That is how my room and Message models look: class Message(models.Model): """Chat message model""" body = models.TextField() sent_by = models.CharField(max_length=255) created_at = models.DateTimeField(auto_now_add=True) created_by = models.ForeignKey(User, blank=True, null=True, on_delete=models.SET_NULL) class Meta: ordering = ('created_at',) def __str__(self): return f'{self.sent_by}' class Room(models.Model): class Meta: verbose_name_plural = "Rooms" unique_id = models.CharField( max_length=8, primary_key=True, editable=False, unique=True) owner = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=101, null=True, blank=True) password = models.CharField(max_length=50, blank=True, null=True) users = models.ManyToManyField(User, through='UserRoom', related_name='users_room') messages = models.ManyToManyField(Message, blank=True) def __str__(self) -> str: return str(self.name) I have added the consumers to my urls: path('ws/<str:room_id>', chat_consumers.ChatConsumer.as_asgi()), And configured my … -

List of all values in Django model attribute
I am creating an e-commerce website and I want to allow the user to filter the search results by various products specs. I want to return in my API a meta dictionary containing all the values each product attribute has. For example, if the user searches for 'iPhone', the response should look like this: { 'data': { ... }, 'meta':{ 'options':{ 'model': ['iPhone 12', 'iPhone 13', 'iPhone 14'], 'manufacturer': ['Apple'], ... } } } Here is my model for reference: class Product(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=255, null=False, blank=False) description = models.TextField(max_length=2048, null=False, blank=True) price = models.FloatField(null=False, blank=False, default=0) model = models.CharField(max_length=255, null=False) manufacturer = models.CharField(max_length=255, null=False) seller = models.CharField(max_length=255, null=False) So far i have tried using this, where products is my QuerySet of Product entities after applying the 'iPhone' search: products.values_list('model') The problem with this is that it returns a QuerySet, but I want a list. I was hoping there is a one-liner that I don't know about. -
In Django Admin, how do I reference reverse foreign key relations for `list_display`?
In my app, we may have new languages or dialects of languages appear at any time, and text written in one language or dialect may need to be translated into another. That's why we handle text by relating text in different languages into "families" (i.e. the translation set into different languages). class StringFamily(models.Model): id = models.AutoField(primary_key=True) # plus some other fields class String(models.Model): id = models.AutoField(primary_key=True) # the reference to StringFamily family = models.ForeignKey(StringFamily, null=False, on_delete=models.CASCADE) # other important stuff language = models.ForeignKey(Language, on_delete=models.DO_NOTHING) dialect = models.ForeignKey(Dialect, null=True, on_delete=models.SET_NULL) text = models.TextField(null=False) Unfortunately this complicates using the Django ORM. When we hit a problem with the app, we're generally saved by using raw SQL to deal with this setup. But I also want to use the Django admin, and I don't see any SQL workaround there. In particular, there are all sorts of models that have some text that may appear in multiple languages, like so: class Element(models.Model): id = models.AutoField(primary_key=True) element_role = models.ForeignKey(ElementRole, null=False, on_delete=models.RESTRICT) string_family = models.ForeignKey(StringFamily, null=True, on_delete=models.SET_NULL) # plus more fields What I want is to be able to something like this (everything here works except "display_english_string"): class ElementAdmin(admin.ModelAdmin): list_display = ("element_role", "display_element_type", "display_english_string") This works … -
Goal: How to dynamically create field named status to be display end user side using django?
I am working on a personal web page that ideally would tell me the status of my groceries for example: expired and unexpired based on some input such as date bought and expiration date printed on the products. I am new to the django framework but I been learning a lot online and using chatgpt, youtube and reading articles to explain some of the concepts and how to use it. I am currently stuck on why the code that dynamically generates the status field in the function get_context_data(), at the moment it works but I am confused why it works since it was a suggestion by chatgpt. I am unsure why do I have to write context['allproducts'] = productStatus instead of simply create a context['status'] = productStatus then call status in the variable for all elements in the Products model. The datatype for the productStatus is Queryset but it appears to be behaving as a dictionary when I use the assignment operation for product.status. I you could explain why it is actually working would be amazing since it is not obvious to me how the productStatus is receving this product.status column. Is this the best practice on how to dynamically … -

How to make a Custom Response class in Django REST framework
I am using django rest framework api as the backend for my project. I treid making a custom Response class for the project and put together the code shown below: class CustomResponse(Response): def __init__(self, error=None, message=None, data=None, status_code=None, *args, **kwargs): self.error = '' if error is None else error self.message = {} if message is None else message self.data = {} if data is None else data self.status_code = status.HTTP_200_OK if status_code is 1 else status.HTTP_400_BAD_REQUEST return super().__init__(data = {'error': self.error, 'message': self.message, 'data': self.data, 'status_code': self.status_code}, status=self.status_code, *args, **kwargs) Is there a better way to do this? Like should I expand some more on this CustomResponse class or should I create a completely new one in some other way? The CustomResponse is to be used for returning serialized data from Views that are made by inheriting the APIView. I was using Response directly for this and I wanted to make something that allows me to add extra details easily according to whether the Response was for something that succeeded or if it had some sort of errors. I searched a lot and everything that I found was similar to the code I made above. But I feel like something … -
How can I handle user authentication in my Remix app if I'm running a DRF backend?
I have Remix app which which relies on a django rest framework api as the backend for data(including users'). In the API, I use JWT to handle user authentication but now that i want to connect it to my remix app, I'm not sure of the best approach on implementing this jwt authentication from the frontend(remix app) or if I should be using a different authentication backend entirely in my API. I've created a sign up page that sends user credentials to the sign up endpoint which creates the user and to sign in, I also send user credentials to the login endpoint which returns the access and refresh tokens. For now, I save this tokens in localStorage(i know this is insecure) and include them in the headers of any requests to endpoints with auth or permissions. Also, in the root module of my remix app, i get the access token(if avaliable) from LS and make a request to the endpoint to get the current user context and pass this into the root component as context. This is stressfull, inefficient and insecure. What is a better, more secure approach to achieve this? -
Django FileResponse crashes with large files
...I have a Django application with a lot of data and a MariaDB database running on a Raspberry Pi (OS = Debian 12). The application uses Daphne as Webserver because there are also Django Channels components in there (Websocket). Now I want to implement a backup feature, that automatically dumps the database, zips together the dump with the other data files and has the browser automatically download the ZIP-file. So I made a view for the download: def downbackup(request): if request.user.is_superuser: filename = '../temp/backup/backup.zip' sourcefile = open(filename, 'rb') return FileResponse(sourcefile) else: return(HttpResponse('No Access.')) That view is called from the relevant template via url and verything is fine. Until we meet large files in real live. In this case (filesize around 6 GB) Daphne immediatly stops operation, and the Raspi crashes so deep that I have to switch power on and of. Also, in Monitorix I see huge memory consumption spikes after these crashes. But there is no error message in the Daphne logs, in the Django logs (incl. debug-setting) nor in the journalctl. Nginx (the reverse proxy) reports an uplink timeout (504). I think I learned from the Django documentation the FileResponse buffers the file to avoid memory consumption, but …
