Django custom permission class is not working
I am using Django REST for my API. Here is my custom permission class: permissions.py: from rest_framework.permissions import BasePermission from rest_framework.response import Response class ItemsPermissions(BasePermission): def has_permission(self, request, view): try: request_data = request.data print(request_data) auth_token = request_data['returnedDataFromAuthAPI'] if("accessToken" in auth_token): auth_token = auth_token['accessToken'] Response({"Permission Granted - AccessToken": auth_token}) return True #else Response({"message": "No Auth Token Provided! You Need To Login!"}) return False except Exception as ex: return Response({"message": ex}) in views.py: class ListItems(generics.ListAPIView): permission_classes = [ShippingPermissions] queryset = myModel.objects.all() serializer_class = mySerializer in urls.py: url_patterns = [ path("/items/list/", ListItems.as_view()), ] I have an authentication microservice that I get the JWT Token from, for the user to have access to the views. In the ItemsPermissions class I am checking the token. My Question: I want to grant the user access to the ListItems class, after the token is provided, but if token is not provided then the user should not have access. However, for some reason, I am able to access the /items/list/ endpoint, and it does not ask me for a token at all. What is the problem ? -
cannot cast type date to time without time zone LINE 1: ...COLUMN "creation_date" TYPE time USING "creation_date"::time (DJANGO - Heroku)
I am trying to upload my Django-project to Heroku.

Gunicorn [CRITICAL] WORKER TIMEOUT, When redirection
I'm newbi in development. I would appreciate it if you could help me solve this problem. I'm making a social login system in Nginx + gunicorn + Dango by DRF. An error occurs when I request GET {api-path}/kakao/login from my server. My server has to serves to give user's token and to redirect user. The new/old user login is completed successfully, But ** user's page doesn't switch and doesn't get the token.** when I run python manage.py runserver 0.0.0.0:8000, No error occurs and a normal token value is returned. But If I use gunicorn or uwsgi, the error occurs. How can I solve this problem? I have summarized my attempts and my code below. 1. I tried https://www.datadoghq.com/blog/nginx-502-bad-gateway-errors-gunicorn/ check "Gunicorn is not running" other requst like {api-path}/admin works normally. check "NGINX can’t communicate with Gunicorn" other requst like {api-path}/admin works normally. check "Gunicorn is timing out" When I runed python manage.py runserver 0.0.0.0:8000 and tried the problematic request, It took only 2 ~ 3 seconds to response. Because gunicorn's default time limit is 30 seconds, I think reason of my error has nothing to do with Nginx's timing out & Gunicorn's timing out. I tried uwsgi, uwsgi's socket too, but … -

fetch is returning html rather than JSON response
I am working on the cs50 web development project Network. Basically building a twitter copycat. It is still in process but so far I have two fetch requests for a JSON response. Once works perfectly but the other, which is a very similar request, returns html instead of JSON, causing an error. Can't figure out why this one doesn't work. Code snippets below: Here is the one that is returning html for my profile.html file for some reason. The commented out parts are the actual fetch JSON request but I temporarily changed it to show me in the console what is was returning. profile.js: function load_posts_profile() { console.log("load_posts_profile running"); document.querySelector('#prof-posts').style.display = 'block'; fetch(`/profile_posts`) //.then(response => response.json()) .then(response => response.text()) .then(text => console.log(text)) //.then(posts => { // Print posts //console.log(posts); //posts.forEach(post => show_posts_profile(post)); //}); } profile.html: {% extends "network/layout.html" %} {% load static %} {% block body %} {% if user.is_authenticated %} <!--insert profle name below in h3--> <h2 id="profile-name"></h2> <br> <h4 id="followers"></h4> <br> <h4 id="following"></h4> <!--add js to load user's posts only--> <div id="prof-posts"> </div> {% else %} <strong> Login To See Profile</strong> {% endif %} {% endblock %} {% block script %} <script src="{% static 'network/profile.js' %}"></script> {% endblock … -

How can I add new URLS to Django 3.2 under /admin?
I am working on upgrading an old Django project to 3.2. Previously, our urls.py for the main project included the following so that the urls from impersonate were below /admin url(r"^admin/", include(admin.site.urls)) url(r"^admin/impersonate/", include("impersonate.urls")), When I update this code to django 3.2, I don't seem to be able to include any urls beneath /admin. The following code: re_path(r"^admin/", admin.site.urls), re_path(r"^admin/impersonate/", include("impersonate.urls")), does not work, but it does work if I modify the impersonate line to: re_path(r"^impersonate/", include("impersonate.urls")), Basically, I want to preserve all of the impersonate urls to be beneath /admin, if this is still possible. I understand that this does not make them require admin permissions, rather this is just to group all the admin views of the project together. I have seen that I can write a custom ModelAdmin also, but this will still move the urls to under /admin/myapp/mymodel/my_view/. I do not want the extra part of the path mymodel here. -
Azure app service SSH connection refused. not using Docker. Django not installing from requirements

How to perform an http post request to a device behind a router using DDNS & Python
For faster prototyping of my code, I would like to provide my laptop address as an endpoint to the http webhook API (Base URL) of the website cloud.thethings.network. For this, I setup a ddns on noip.com and connected my tp-link router with my noip-account. So right now, I have sth. like myneedddns.ddns.com that forwards to my router. I’ve also set port forwarding in my router to access my laptop and reserved a static IP for the laptop: However, I can not provide a format like xxx.ddns.com:801 on thethingsstack. From there I can probably handle how to receive the request with flask or django. How would you approach my goal? -
Unique Class or extend Class or Subclass in Python Django?
Unique Class or extend Class or Subclass in Python Django? In the following situation, I have a feeling I need to ?extend? the Migration class instead of re-stating it in the second module.

How to obtain a user instance using django rest framework
Perhaps the question is wrongly worded. I created user profile using Django through the following blocks of code: models.py class = Profile (models.Models): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) first name = models.CharField(max_length=50) ••• serializer.py class profile_serializer(serializers.ModerlSerializer) class Meta: model = Profile fields = '__all__' views.py class profile_view(generics.ListCreateAPIView) queryset = Profile.objects.all().filter(user=instance) urls.py urlspatterns = [path('profile', profile_view.as_view(), name='user_profile) I definitely do not know how to implement the filter method to ensure that only the logged in user is retrieved. Or is there a better approach to obtain a specific user? If I use Project.objects.all() without the filter I get all the registered user as expected. But I don't know how to retrieve a particular user. -
Problem with progress upload bar using XMLHttpRequest in Django

Django Rest Framework request unauthorized on all but one address
I'm trying to access django hosted at 192.168.x.x:8000 on a React frontend server on port 5002, when attempting to access the frontend with localhost, 127.0.0.1 or ip's outside of the home network, it gives following result in console: Unauthorized: /api/any_endpoint HTTP POST /api/any_endpoint 401 [0.03, 127.0.0.1:12345] However when accessing trough 192.168.x.x:5002, it just works. the /admin/ endpoint seems to work no matter the ip address (ip_address:8000), so it's either django-rest-framework or React that is causing this issue. I have no idea where to start debugging this, so any comment on what I should check would be appreciated -
