Getting a 403 Forbidden message in a Django 4.2 POST request even after including the CSRF token
I am trying to perform a language toggle feature in a website and I am using Django 4.2 and using Django's i18n library in the root level urls.py file. urlpatterns = [ path('i18n/', include('django.conf.urls.i18n')), ]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) urlpatterns += i18n_patterns( path('',apiView.WebsiteHomepageTemplate.as_view(),name="url_homepage_template"), ) In the template file , I am performing the language switch like this : <ul class="dropdown-menu" role="menu" id="language-list"> <li class="" id="language-switcher"> <form action="{% url 'set_language' %}" method="post" name="lang_form"> {% csrf_token %} <input name="next" type="hidden" value="/" /> <select class="selectpicker" id="select_pickr" name="language"> {% get_available_languages as LANGUAGES %} {% get_language_info_list for LANGUAGES as languages %} {% for language in languages %} <option value="{{ language.code }}" {% if language.code == LANGUAGE_CODE %} selected="selected" {%endif %} data-content='{{ language.code }}}'> {% if language.code == 'en' %} English {% else %} हिंदी {% endif %} </option> {% endfor %} </select> </form> </li> </ul> When I perform the toggle, I get a 403 forbidden message.

Override Django Admin 'add' form template and form processing
Summary: I want to change the 'add' template in Django admin. I want to display an HTML form, which I want to processes and save some data into the database. This form and the data I'll save aren't directly rows in a model. I can override the template with add_form_template, but can't figure out how to use a Django Form object within that. I have a self-referential model, where several rows may link to a single row. This linkage is to be performed by a human. For example, we might say "Select all the fruits", and list apples, oranges, bananas and cashew nuts. The next "row" of the form would say "Select all the cars", with a list of "Mini", "Jazz", "Fiesta" and "F150". We'd maybe show 10 such rows on the form, the human would select all the fruits, and cars, and do the same thing on the other 8 rows, and press submit. We'd then read the form data, and set the 'link' for all the fruits to the "All Fruit" row's ID (and same for the cars and other things). This workflow doesn't follow the usual 'add a row' (or 'many to many') style that Django admin … -
MIME type error with npm libraries in ReactJS
I am currently creating a Django + React application. I am currently using React 18.2.0 and Django 4.2. I have my application completed when Debug=True in Django. However, once I perform the operation: DEBUG = False ALLOWED_HOSTS = ["*"] The website breaks once I change these lines of code. When I look into the console in the website it displays the error: Refused to execute script from 'http://localhost:8000/static/js/main.94957794.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled. I got three of these errors each depending on if it was a stylesheet or javascript. After a few hours of tinkering around I manage to figure out that the problem was with some libraries that I am using from npm (react-animation, Animate.css and countries-list). React Animation is an out-of-date library and had to downgrade to React 16.8.0. (Idk if that is a possible reason). How would I solve these errors? I am just very confused as the website works when DEBUG = True but not when DEBUG = False. My main problem is that the website just doesn't work altogether when I set DEBUG = False. Does anyone have a solution to this? I have tried … -

My django views/login form are not working properly
I am doing a final project for a programming certificate (Python programming). I have stumbled upon a problem when it came to my views.

Django rest api and axios post request doesn't work
I am trying to make a simple api where a user writes something in an input, presses a button and a new instance is added in a database. To do this I am using react and django rest framework.

Video encoding task not working with Django Celery Redis FFMPEG and GraphQL
I'm having a hard time trying to understand how is this FFMPEG encoding works while using Django, Celery, Redis, GraphQL and Docker too. I have this video / courses platform project and want I'm trying to do using FFMPEG, Celery and Redis is to create different video resolutions so I can display them the way Youtube does inside the videoplayer ( the videoplayer is handled in frontend by Nextjs and Apollo Client ), now on the backend I've just learned that in order to use properly the FFMPEG to resize the oridinal video size, I need to use Celery and Redis to perform asyncronus tasks. I've found a few older posts here on stackoverflow and google, but is not quite enough info for someone who is using the ffmpeg and clery and redis for the first time ( I've started already step by step and created that example that adds two numbers together with celery, that works well ). Now I'm not sure what is wrong with my code, because first of all I'm not really sure where should I trigger the task from, I mean from which file, because at the end of the task I want to send … -
Prometheus cannot find Django /metrics
Im using the prometheus client library for Django. I am not running prometheus in a Docker container. The Djanog application is bound to Unix domain sockets, so I think that is part of my issue but idk how to resolve. NGINX is listening on port 80 and re-routes traffic with the proxy_pass header. I dont understand how my node_exporter (server metrics) works fine with the local host target, but my application will not. Even from a browser I can access "/metrics" endpoint. I've tried localhost, 127.0.0.1, and even the server IP and nothing works. Also, IPtables has nothing related to port 80, yet I've created a "denied" log record and Im getting "... src=127.0.0.1 dst=127.0.0.1 dpt=80 [...]" NGINX erver { server_name hotname www.hostname ip; [...] location /metrics{ proxy_pass http://<unix_domain>; } location / { proxy_pass http://unix:<location_of_domain_socket>; } prometheus <default prom config> [...] static_configs: - targets: ["localhost:9090"] - job_name: "django-app" scrape_interval: 10s static_configs: - targets: ["localhost] # nothing works and prometheus attempts to use port 80 with a predefined scheme of http:// - job_name: "node" scrape_interval: 10s static_configs: - targets: ["localhost:9100"] -
Best Approach for Developing a Cross-Platform Mobile App alongside a Django Web App?
I’m currently working on building a Django app, and I anticipate that it will eventually require a cross-platform mobile app as well. While the Django web app can be designed to be mobile responsive, I’m considering the option of developing a native app. I’ve done some research, and it seems like React Native could be a good choice. However, I’m open to suggestions since React Native involves a completely different world and language compared to Django and Python. I’d appreciate any recommendations or insights you may have regarding the best route to take for building a native mobile app alongside my Django app. -

Django template render speed issue for large queryset
I have completed a web application for work and was doing some various tests. One of the tests was for a "exaggerated" number of items on a given page and how long it would take to load (the page is basically a dashboard for a helpdesk system) . My results are quite bad with the test page taking some 20 to 25 seconds for 1200 items on a standard spec system and 3 - 10s on a very high spec system. I dont ever expect the active calls to reach that number on the dashboard but am looking at a worst case scenario. I have also tried with pagination, but I am probably implementing it wrong as going to the next page seems to rerun the queries and takes the same time as displaying all 1200 items irrespective of whether I am displaying 1 item or 10. As the project is quite large and contains sensitive information, I cant really provide the code here for reproducible results but I created another basic project that basically highlights what I am experiencing. It can be downloaded here: https://drive.google.com/drive/folders/19yvzHugC7hjcVJpiHeYiEjyX-SA2_wu3?usp=sharing This code is not that bad as not many attributes are referenced in the … -

Django - Celery - How to handle complex tasks
Following problem needs to get solved: In my Django project I have to collect, manipulate and save specific data on regular basis. Example: Every minute I have to retrieve data from a heating-system via REST-API and process them Every minute I have to retieve data from a PV-inverter via REST-API and process them Every six hours I have to retrieve data from an external data provider and do some processing on it. After midnight I have to do some calculation on data from previous day ... and more to come in future From my perspective the Django/Celery/Beat approach would fit for above scenarios. I'm aware it's not a real message-based use case - more a batch processing use case to not setup cronjobs. In my Django project I have created apps (for the specific subsystems) and some general packages on project level. Described scenarios can be called (from Python shell and via Bash script outside development via cronjob. Now I tried to use Celery Beat to orchestrate above scenarios. But I'm not able to call the scripts from inside the celery tasks. Simply nothing happens - I guess importing all packages and scripts fail. I worked with several tutorials to … -
