How can I create a user login/registration model using Django Rest Framework without getting a response code 403 when trying to create user?
So I am working on a project using Django and Django rest framework. I'm trying to create an api for my website which allows users to register/log in/log out. I'm following [this tutorial] (https://iheanyi.com/journal/user-registration-authentication-with-django-django-rest-framework-react-and-redux) for the initial set up. My issue is that when I try to run my test code to create a user, I get a response code 403 which I guess means I'm trying to do something I don't have permission to do? How can I get rid of this issue so I can create users? Here is my tests.py: from django.test import TestCase from django.urls import reverse from rest_framework.test import APITestCase from django.contrib.auth.models import User from rest_framework import status class TestUserApi(APITestCase): def setUp(self): self.test_user = User.objects.create_user('testuser', 'test@example.com', 'testpassword') self.create_url = reverse('user-create') def test_create_user(self): data = { 'username': 'foobar', 'email': 'foobar@example.com', 'password': 'somepassword' } response = self.client.post(self.create_url , data, format='json') # We want to make sure we have two users in the database.. self.assertEqual(User.objects.count(), 2) # And that we're returning a 201 created code. self.assertEqual(response.status_code, status.HTTP_201_CREATED) # Additionally, we want to return the username and email upon successful creation. self.assertEqual(response.data['username'], data['username']) self.assertEqual(response.data['email'], data['email']) self.assertFalse('password' in response.data) def test_create_user_with_short_password(self): data = { 'username': 'foobar', 'email': 'foobarbaz@example.com', 'password': 'foo' … -

How to create and change ownership of a directory from within a Docker container
I have a Django app with an api endpoint for creating a directory for a user. When receiving the request, the app runs subprocess.check_output to create a directory for the user in an NFS mount and then run chown so that only that user has the proper permissions to add files to the directory. Now, I'm trying to migrate the app to run inside a Docker container but need to retain this functionality. What is the best way to do this? I've thought of having a volume to the NFS mount in the host machine but I'm not sure if that works, specially since the user wouldn't exist inside the Docker container and hence chown would fail. Something else I thought was having a shell script which can be called from the Docker container and run in the host machine but I don't know if that's possible -

Tinymce doesn't generate pre-signed urls for uploaded images
I am developing a Django blog application where I utilize Tinymce as the text editor for the content of the posts. To store the uploaded images, I use AWS S3. The problem is that Tinymce does not generate pre-signed URLs for the uploaded images, leading to access denied errors when the expiration time is reached. This is the error I get: AccessDenied Request has expired 3600 2023-06-07T03:26:09Z 2023-06-07T15:46:49Z xxxxxxxxx xxxxxxxxx When an image is uploaded through Tinymce, it is stored as a link in the text area. However, Tinymce does not generate new pre-signed URLs for the images when a post is opened, resulting in the images retaining the same URL that was initially generated during the post's save operation. Since the pre-signed URLs for the Tinymce images do not change, when the expiration time set for the URLs is reached, the images become inaccessible, and I encounter an "access denied" error. I have other images in the blog that are served fine. The problem is just happening with those uploaded in Tinymce These are some relevant code snippets: uploadfile.js const image_upload_handler_callback = (blobInfo, success, failure, progress) => { const xhr = new XMLHttpRequest(); xhr.withCredentials = false; xhr.open('POST', '/' + … -
Design pattern for Yelp-like app using microservices
I'm a newbie in microservices so forgive me if my question sounds a little naive. I'm designing a Yelp-like app for gyms. in this application, users can create a gym and its related data, and others can review or rate it. My question is how to design its services in microservice architecture? Is it a good design pattern to create these three services? Auth service that has a user table and manage user related data for login and registeration. Gym service for gym CRUD operation such as posting a gym, updating it, and so on. User service for relating gyms to their owners through event-driven architecture and message broker like Kafka. it also manage user profile data, such as resetting the password or changing the username, email, first name and last name. If this approach is reasonable, I want to know how does the relationship between user and auth service works. do I need to keep all the user data in the auth service and fetch or update it through published events, or should I duplicate the user data in a new user table in the user service database? -
Filter nested Django objects in serializer
In an application I am working on I would like to filter the objects returned by a serializer based on the user's is_staff status. If a user has is_staff = True I would like for all of the nested Book objects to be returned. If the user's is_staff status is False I would like for only Books with active = True. How can I achieve this using this viewset: class BookCategoryViewSet(viewsets.ReadOnlyModelViewSet): """ View available books by category """ queryset = BookCategory.objects.all() serializer_class = BookCategorySerializer and these serializers: class BookSerializer(serializers.ModelSerializer): """ Serialize Book for list endpoint """ class Meta: model = Book fields = ( 'id', 'name', 'description', 'category', 'category_name', 'thumbnail', 'active', ) class BookCategorySerializer(serializers.ModelSerializer): """ Serialize books by category """ books = BookSerializer(many=True, read_only=True, source='book_set') class Meta: model = BookCategory fields = ( 'name', 'active', 'books', ) NOTE: I am trying to filter the Books not the BookCategories based on the user status. -

Is it possible to return a Django.model instance with htmx?

Authentication for grafana behind a reverse niginx proxy
I am running a react app with a django backend. Users can log in to my app via django and are redirected to my react app. Now I want to show a grafana panel. I already set up a self-hosted grafana instance with a reverse proxy (for https). I can embedd the panel without a problem (iframe) when I use grafanas anonymous_authentication.
