AWX + Hashicorp Vault django.request Bad Request
In order to improve my AWX management for my team, i'm currently trying to configure Hashicorp Vault Credentials but i'm having some errors and doubt. Usually in my Ansible project I run from a Debian server, I'm used to set up Vault secrets using lookup like this (works in var file or within vars:) ### Vault Configuration ansible_hashi_vault_token="{{ lookup('env','VAULT_ANSIBLE') }}" my_secret="{{ lookup('community.hashi_vault.vault_kv2_get', 'my_secret', engine_mount_point='kv/', token=ansible_hashi_vault_token) }}" #### Credentials (compte de service ansible) #### ansible_user="{{ my_secret.secret.ansible_user_from_vault}}" Ansible will seek for an environment variable which is called 'VAULT_ANSIBLE' that is the result token of an AppRole call to my vault server. It allows to run playbook without writing any token in the code. Now after adding project in AWX, i'm trying to make the Vault part working => I created Credentials with HashiCorp Vault Secret Lookup as you can see here. Simply add Server URL + Token for testing. When I click on Test, no matter what secrets I want to retrieve I always have this error Here's my questions : which log file can give me more information about the credentials/api call to Vault? Is there any thing I miss for this peculiar configuration ? I tried to add my root.CA … -

Django Production Deployment Issue: Blog Articles Stacking and Unexpected <strong> Tags
I'm facing a rather perplexing issue with deploying a Django site on which I'm working. I'm using Django version 4.2.5, and my development environment is on Windows. The production deployment is on O2Switch using CPanel. To deploy the code, I'm using CPanel's Python Application Manager and fetching the code via push/pull from GitHub. The problem I'm encountering is as follows: after the production deployment, the blog articles are not displaying correctly. Instead of appearing side by side, they are stacking on top of each other. This issue doesn't occur locally, and upon investigation, I noticed that <strong> tags are being generated with each iteration, disrupting the styling I've implemented. Screen of code with inspector Screen of code with inspector Screen render in prod Screen render in prod I tested the site in a pre-production environment on a test URL (on the same server but in a different directory), and everything works correctly. However, once in production, the issue arises. Do you have any ideas about the possible cause of this unexpected behavior during production deployment? Thanks in advance for your assistance and suggestions! Additional context: Development environment: Windows Production environment: O2Switch with CPanel Django version: 4.2.5 I've included screenshots of … -
Django change fuzzy threshold while running makemessages
When Im running python manage.py makemessages I have fuzzy lines in my django.po file, for example : #, fuzzy #| msgid "Last Month" msgid "Last Year" msgstr "Dernier mois" This is due to the gettext.merge command used by django as explained here : https://hexdocs.pm/gettext/Mix.Tasks.Gettext.Merge.html#module-options To solve this issue, I should use the --no-fuzzy tag or reduce the --fuzzy-threshold. But my issue is that there is no way to do that using django makemessages command (at least I can't find it) Is there a workaround I can use to fix my problem please? -
How to overwirte Django Backend?
I would like to give access to the backend of a Django project for all my users who is registered in a specified Azure AD group. I use django_microsoft_auth package to handle SSO Usage — django-microsoft-auth When I log for the 1st time with an account from Azure AD, the account is created in Django. But I would like to : change the loggin (by default is using the email address as loggin), force is_staff = True and add the user to a django group.

Frontend + backend on aws lightsail
So I have a webapp with reactjs as frontend and django as backend and mysql as database. Now I have my django deployed on heroku which i want to put on my lightsail server as well. My frontend is also deployed on lightsail same as my mysql instance (I did not use containers). It for now only has 1 page as the webapp was not yet ready. Now that everything is ready I want to deploy everything on the Lightsail server. It has 2gb of RAM and 1vCPU. I was wondering what the best way is to go about the deployment of this. My main concern is about concurrent users, with the biggest concern being the backend (not sure how many concurrent users it can hold). So my questions is can this server hold many concurrent users (i know you need more information to calculate this so approximation is fine) I look forward to hearing everyones ideas thanks! -
How can localhost and 127.0.0.1 share the same request in Django/Vue?
In my Django application, I'm authenticating a user on the backend, with port 8000. Upon success, the user is redirected to the frontend on port 5173. After configuring CORS and CSRF correctly, I was able to successfully reproduce this when I accessed localhost:8000/login. It redirected to localhost:5173/ and the authenticated content was provided. The issue is however, when the user attempts to access the URL provided by Django (127.0.0.1:8000), it gets redirected to the localhost:5173 origin, meaning they don't share the same resources as they are different URLs. Are there any practices or workaround in this scenario? Or is it assumed that the user should always be accessing localhost? I tried to execute the same_site= None option, however, I believe that is for HTTPS which I have not configured yet -
Can I generate token using DRF after I validate the user using LDAP?
In the beginning I will ask everyone to excuse me if my question is wrong/not properly framed because I am new starting something new which I am totally not aware of, I need to learn this as it is very much needed for my work. Question goes as below, I am planning to develop a framework using Django, to authenticate users to use my framework I need to validate user using my org LDAP. In my framework I have multiple API endpoints (as I am developing API end points using Django), for each end point I need user to have permission/authentication. Here is the catch, when I am trying to authenticate user using LDAP I am not able to generate tokens (access or refresh). If I generate token I am not able to authenticate user using LDAP. I tried integrating both part but I am getting error ( may be I dont know how to integrate as I am new to Django). I need help from you guys like....I need to validate user using LDAP and after validation I need to generate token (access and refresh). Please help me with this... Below is my code snippet.

how to automatically kill sessions on postgres db in python django, before django tests recreate the db
django recreates our postgres test database on start, however in some cases there are sessions open. I can kill the sessions with SELECT 'SELECT pg_terminate_backend(' || pg_terminate_backend(pg_stat_activity.pid) || ');' FROM pg_stat_activity WHERE pg_stat_activity.datname = 'MY_DBNAME' AND pg_stat_activity.pid <> pg_backend_pid(); but currently, I do that manually as needed from SquirrelSQL. How can this be done automatically before django recreates the DB (very early in the test setup process). THis is needed because otherwise the delete DB fails due to connected sessions. -
Can't figure out how to make a simple "add to favourite" view with Django and HTMX
In my streaming app (for portfolio), I've been trying desperately to make a very simple function to add a film to a user's list. The simple thing : a heart, when you click it adds or removes the film to your list and change the heart colour. I'm trying to make it with a class based view and with HTMX. All of the similar application I found online were made with function based views and older version of Django. I don't want and copy/paste weird code, I want to understand. But whatever I do (just spent 2 hours with ChatGPT, trying a million thing), I keep on getting one of two errors : a Method Not Allowed or a NoReverseMatch. Whatever I do, I get one of these. I've tried many different things, but right now, this is my code : My view : class AddToFavoriteView(CustomLoginRequiredMixin, UpdateView): model = Film fields = ["favorite"] template_name = "includes/heart.html" http_method_names = ["get", "post"] def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) if self.object.favorite.filter(id=self.request.user.id).exists(): context["is_favorite"] = True else: context["is_favorite"] = False print(f"is_favorite: {context['is_favorite']}") return context def post(self, request, *args, **kwargs): self.object = self.get_object() print("Trying to add to favs.") film = Film.objects.get(pk=self.object.pk) print(f"{film.title}") if film.favorite.filter(id=request.user.id).exists(): film.favorite.remove(request.user) is_favorite … -

Optimising Gunicorn Configuration for High-Concurrency I/O-Intensive Tasks with Low CPU and Memory Usage
I'm currently managing a Django application hosted on a 16-core server. Despite having 25% maximum CPU and memory usage, performance starts to degrade at around 400 active connections according to Nginx statistics. Currently, we have 12 Gunicorn workers, which is lower than the recommended (2 * CPU) + 1. However, as per Gunicorn's documentation, 4-12 workers should handle hundreds to thousands of requests per second. Question about Worker Configuration: Has anyone successfully used a number of workers exceeding the 12 as mentioned, especially in scenarios with low CPU and memory usage? Any insights into optimal configurations for high-concurrency scenarios in such situations? Performance Optimization: Our application primarily involves I/O tasks. Despite optimizing database queries and having low CPU and memory usage, performance remains an issue. Would increasing the number of workers or introducing threads (summing up to (2 * CPU) + 1) be a viable solution for improving performance in I/O-bound scenarios with seemingly underutilized resources? This means setting workers to 33 if I use (2 * CPU) + 1, or maybe 10 workers with 3 threads? Additional Considerations: We are considering tweaking Gunicorn configurations, but want to ensure we're on the right track given the low CPU and memory … -

Django Autocomplete Light: multiple selection from List (not Model)
I know how to use DAL (Django Autocomplete Light) to allow a single selection, like in the tutorial: CHOICE_LIST = [ ['FR', 'France'], ['FJ', 'Fiji'], ['FI', 'Finland'], ['CH', 'Switzerland'] ] class CountryAutocompleteFromList(autocomplete.Select2ListView): def get_list(self): return CHOICE_LIST class CountryForm(forms.ModelForm): country = autocomplete.Select2ListChoiceField( choice_list=CHOICE_LIST, widget=autocomplete.ListSelect2(url='country-list-autocomplete') ) However, I can't find any lead in the documentation or DAL source code to implement multiple selection, e.g. to allow users to pick 2 countries or more. Has anyone a working example I could learn from? -

How to render in real-time the django model's field using django channels?
I already set up the connection between the server side which are the asgi.py, consumers, and routing, that is already listening to client side using javascript.
