can't retrieve images from filesystem with Next.js and Django
English is not my native language. I'm trying to deploy three Next.js apps and one Django API app(using Django ninja). the problem is I get "400 bad request" in my browser's console. https://MY_SERVER_DOMAIN/users/_next/image?url=https://MY_SERVER_DOMAIN/media/magazine/thumbnail/Methods-of-using-radish-in-diet.webp&w=1920&q=75 in local I can see the image but on production I get 400. my Nginx config: location /media/ { alias /home/USER/backend/media/; } location /api/v1 { include proxy_params; proxy_pass http://localhost:8000; } location /admin { include proxy_params; proxy_pass http://127.0.0.1:8000; } location / { include proxy_params; proxy_pass http://localhost:3000; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } location /doctors { include proxy_params; proxy_pass http://localhost:3001; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } location /users { include proxy_params; proxy_pass http://localhost:3002; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } } I saw many errors like this this in /var/log/nginx/error.log: 2025/04/06 13:44:21 [error] 41446#41446: *1 directory index of "/home/USER/users-front/.next/static/media//" is forbidden, client: 5.125.0.145, server: 176.97.218.11, request: "GET /users/_next/image/?url=%2Fusers%2F_next%2Fstatic%2Fmedia%2Fdoctor.07a8ef12.jpg&w=96&q=75 HTTP/1.1", host: "MY_SERVER_DOMAIN", referrer: "https://MY_SERVER_DOMAIN/users" but it should retrieve the image from Django media directory("backend/media") not Next.js! -
CORS headers not being added in django
Preface, I am aware of django-cors-headers not work I am getting the following error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at ... (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 301. Here are the important parts of my settings.py. INSTALLED_APPS = [ ... corsheaders ... ] corsheaders is the last entry in INSTALLED_APPS MIDDLEWARE is: MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.middleware.common.CommonMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', "allauth.account.middleware.AccountMiddleware", ] So CorsMiddleware is at the top. And for CORS settings: CORS_ALLOW_CREDENTIALS = False CORS_ALLOW_ALL_ORIGINS = True And ALLOWED_HOSTS is: ALLOWED_HOSTS = ['*'] Online, this seems to be all that's needed to get CORS headers, but I am not getting them in the response. How do I fix this? -

Safe keyword usage with Django-summernote inhibits word wrapping even with explicit word wrapping
I am trying to use summernote with django and am encountering this issue where if I paste 200 words of inline lorem ipsum text as a test in the texfield, it correctly shows the text, but in a single line that is too big and goes off screen to the right.

How can I test my Django & React app with massive users efficiently?
I'm working on a Django backend and a React frontend, and I need to test my app with a large number of users. I have used Cypress for UI testing, but it takes too much time to complete the tests I need. My goal is to test two different scenarios: First scenario (8,840 users) Register a user Modify user details Create a contribution Second scenario (~300,000 users) Perform the same process as the first scenario but on a much larger scale I'm looking for a faster and more efficient way to execute these tests. -

Django app with Azure storage account - images are not saved to blob storage container
I have a Django app, and I am trying to store images in an Azure Storage account. I have a database with table category and property name images, where the URL of the uploaded image is saved when a user uploads an image. For example: media/photos/categories/Koesimanse.png However, the image is not being saved in the Azure storage container. When I try to access the URL: https://dier.blob.core.windows.net/media/media/photos/categories/Liza_GUAzhRg.jpeg Then I get this error: BlobNotFound The specified blob does not exist.

However, if I manually upload an image to the Azure blob container and store its URL in the database, the image is successfully retrieved from Azure Storage blob container.

Django Select2 Autocomplete: How to Pass Extra Parameter (argId) to the View?
I'm using Django with django-autocomplete-light and Select2 to create an autocomplete field. The Select2 field is dynamically added to the page when another field is selected. It fetches data from a Django autocomplete view, and everything works fine. Now, I need to filter the queryset in my autocomplete view based on an extra parameter (argId). However, I'm not sure how to pass this parameter correctly. JavaScript (Select2 Initialization) function getElement(argId) { let elementSelect = $("<select></select>"); let elementDiv = $(`<div id='element_id' style='text-align: center'></div>`); elementDiv.append(elementSelect); $(elementSelect).select2({ ajax: { url: "/myautocomplete/class", data: function (params) { return { q: params.term, // Search term arg_id: argId // Pass extra parameter }; }, processResults: function (data) { return { results: data.results // Ensure correct format }; } }, placeholder: "Element...", minimumInputLength: 3 }); return elementDiv; } Django Autocomplete View class ElementAutocomplete(LoginRequiredMixin, autocomplete.Select2QuerySetView): def get_queryset(self): qs = MyModel.objects.filter(...) I want to pass argId from JavaScript to the Django view so that the queryset is filtered accordingly. However, I am not sure if my approach is correct or how to achieve this. Appreciate any suggestions or improvements. Thanks! -

Security on Webapp against hacking attempts
I hava a under-construction django webapp on Heroku. While checking the latest features on the logs, I read a great deal (several hundreds) of rapid succesion GET request, asking for passwords, keys, and other sensible credentials. This is new, we are only 2 people working daily on the website, and it makes no sense as the WebApp doesnt ask and doesnt have these credential, so they are hacking attempts. I know nothing about web security. Sorry if I am asking or saying obvious or wrong things My questions are: what to do now ?
