Django JWT - Allow request with no credential if key in body is valid
I have an endpoint that needs an Access Token for authentication. Also in this endpoint, there's a serializer UUID field that is not required. What I would like to do is: In case the UUID field is passed in the body, check if this UUID is valid and registered in the Database. If it's not valid it'll raise a DRF ValidationError. If no UUID field is passed then the request needs to be authenticated with an Access Token. Is there a way to have this kind of seletive auth verification? -
Highlight Repeated Names
I have a webpage that shows a list of students being requested by teachers for tutoring. A student can only be listed requested once in reality but multiple teachers may accidentally request the same student unknowingly. Is there a way to highlight a student's name each time they are requested except for the first request? The highlighting will be used to signify to teachers that these requests are to be ignored. See attached picture for clarity. Screenshot of Webpage -
Long running request causes connection refused with daphne and nginx
I have a Django 3.2.4 application which I am running on Kubernetes, fronted by NGINX, served via ASGI / daphne. I have a long running API call (no longer than 30 seconds) that when running, seems to cause other requests to be refused. In the NGINX logs I see connect() failed (111: Connection refused) while connecting to upstream and in the pods I see the liveness probe fails (because connection refused), and get Killed 8 pending application instances. Can someone tell me what might be happening? -
How to get currently logged-in user in signals.py file?

Why does my React Dom render method not work?
I'm building a React-Django application, and on my App component, I'm getting an issue on the final line with my render(<App />, appDiv). Please can someone tell me what I'm doing wrong? I have the necessary modules imported, and this worked on my previous project. I am aware that Function-based components are better, but I'm more experienced with Class-based. Error: Code: import React, { Component } from "react"; import { render } from "react-dom"; import HomePage from "./HomePage"; export default class App extends Component { constructor(props) { super(props); } render() { return ( <div className="center"> <HomePage /> </div> ); } } const appDiv = document.getElementById("app"); render(<App />, appDiv); Thanks, DillonB07 -

Can't run makemigrations after moving modules
I've got a module named: validators.py located at ./project/app1/validators.py. I have imported it inside one of my Models: # app1/models.py from .validators import validate_something After a while, I decide to move this validators.py to a separated directory utils/ ("package", __init__.py), so I can use its functions in all my apps without referencing the app1: ./project/utils/validators.py. After moving the module, I changed my import at the beginning of the Model: # app1/models.py from utils.validators import validate_something Now that I want to create new migrations using manage.py makemigrations I'm getting this error: File "project/app1/migrations/0001_initial.py", line 5, in <module> import app1.validators ModuleNotFoundError: No module named 'app1.validators' I can remove all migrations and regenerate them but I guess there should be another way to resolve this dependency issue. -

Is POST only way to send data in django?
So i am creating an application in which am showing university information to students. When the click on apply - i will be showing a modal and asking them to select "Month".

How to iterate over a queryset in django template?
I am aware that this is very likely a duplicate but solutions provided in alike questions did not help. This is at first glance very straightforward issue, it should work by all means but for some reason, it does not. In a Django template, I am filtering a queryset of records based on the current user. Then I loop through it and want to display each result separately. Nothing complicated. The code goes: {% if user.is_authenticated %} {% if user.quick_links.all %} {{ user.quick_links.all }} <h2>Moje rychlé přístupy:</h2> {% for link in user.quick_liks.all %} <div class="col-md-2"> <a href="{{ link.link }}"><button class="btn btn-info">{{ link.link_name }</button></a> </div> {% endfor %} {% endif %} {% endif %} the {{ user.quick_links.all }} displays <QuerySet [<UserQuickAccessLink: Link uživatele david@email.eu: Google>, <UserQuickAccessLink: Link uživatele david@email.eu: Coding Music>]> but then the program never enters the for loop even though the iterable is clearly there. {% for link in user.quick_liks.all %} <div class="col-md-2"> <a href="{{ link.link }}"><button class="btn btn-info">{{ link.link_name }} </button></a> </div> {% endfor %} The above is never executed.

Best way to manage file upload in a django-angular API Rest
I have a Django API Rest as backend and a Angular frontend interface for an app and I'm currently implementing a tool to upload specific files and save them in my server directory or in drive via its own API. My question is what is the best/most formal/correct way to handle this. Maybe angular can take the file and save it? Or should I pass the uploaded file via post request so Django do the necessary logic? I'll thank some example code for the post request if it is the second case.
