Django/Python - How to assign a file path variable in a platform-independent way?
I have a Django project where one of the .env file variables is going to represent an absolute file path. E.g., DEBUG=True SECRET_KEY='blah_blah_blah' MY_STORAGE_PATH = 'D:\\files\\for\\my\\project' Obviously the above would work fine on a Windows machine with a D: drive, but it's no good if there's no D: drive or if the machine is using some other OS. Now I can think of any number of functioning ways to supply this .env string in a platform-independent way, and then use string manipulation and the os.path methods to assemble the actual path. I could break out the drive & path separately, using a 'neutral' path separator of my own choosing: MY_STORAGE_DRIVE_FOR_WIN = 'D:' MY_STORAGE_PATH = '|files|for|my|project' ...I could supply the configuration formatted as a list, convert it to a real list, then feed into os.path.join(): MY_STORAGE_PATH_ELEMENTS = '["files","for","my","project"]' ...and so on, and so on. But before I go roll my own that way, I wanted to know: is there some accepted convention for this kind of use case? (Surely this isn't the first time someone needed to provide an .env value to represent a platform-independent path?) -
Why is my schema execution timing out in python graphene?
I'm using graphene. I was using version 2.1.9. I'm now using version 3.3.

Websocket Connection failing on Deployed Azure web app
I am running a nodeJs server, and serving a ReactApp from it. This is deployed and hosted in an Azure WebApp. I have container running a Django server, hosted on a separate Azure WebApp. I am trying to open a WebSocket connection from my React app directly to my Django server. I have tested this locally by deploying my Django app to azure, and then building my NodeJs & ReactApp LOCALLY and opening the wss:// connection and it works on my machine. But the after deploying the Node/React application to Azure the websocket connection fails with errorcode: 1006 I'm not sure what information settings would give more assistance in solving the issue. I'm completely new to WebSockets as a whole. I'm hoping it's something to do with headers or protocols being stripped/changed as mentioned at the end of this article. But I cannot see anything in my Azure app configuration. I can provide any further information (code or Azure configuration), I just don't know exactly what would help troubleshoot. (My WS connection code, just for transparency) export const awaitWsPing = () => { const socket = new WebSocket('wss://myDjangoApp.azurewebsites.net/my/ws/url'); socket.onmessage = (e) => { const data = JSON.parse(e.data); console.log({data}); notificationContext.setMessage('Received ping … -
How to get authorized in Microsoft AD using curl?
I have a django project which uses Azure Active directory for the authentication and I have set up its API using rest_framework. At the moment, I am trying to access this API using curl. I am able to generate an access token, but when I send a request using it, I get the Microsoft Login Page, as if I do not have any access token. I generated an access token using the following code: curl -X POST https://login.microsoftonline.com/{tenant_id}/oauth2/v2.0/token -H "Content-Type: application/x-www-form-urlencoded" -d "client_id={client_id}" -d "client_secret={client_secret}" -d "grant_type=client_credentials" -d "redirect_uri=https://{my_domain}/oauth2/callback" -d "scope=api://{tenant_id}/.default openid profile email" Then, using the jwt token that I recieved, I did: curl -X GET -L https://<my_domain>/api/benches/1/status/ -H "Authorization: Bearer <token>" And what I get, is the Microsoft login page, which its first few lines look like this: <!-- Copyright (C) Microsoft Corporation. All rights reserved. --> <!DOCTYPE html> <html dir="ltr" class="" lang="en"> <head> <title>Sign in to your account</title> . . .

AWS: How to let a S3 frontend (React, Axios) communicate with an EC2 backend (python3/Django, DjangoREST, corsheaders)
I followed a tutorial for creating a basic To-Do app (so CRUD) with a React+Axios frontend (ServiceWorker, bootstrap) and Django backend (DjangoREST, corsheaders), and would like to put it on AWS's free tier for job-finding purposes. I got the app running fine locally using localhost, and even able to get the server running on EC2 and the frontend hosted on S3 using various other tutorials. Now i'm stuck on how to get them to communicate without them being on the same machine. I had hoped I could just change some lines relating to localhost to their IP's and Ports, but that hasn't worked. Since this is a fairly simple example program I tried to keep security to a minimum throughout setup to help communications, and have allowed HTTP and HTTPS and anything I could * in my security settings. In settings.py I have: ALLOWED_HOSTS = ['*'] CORS_ORIGIN_WHITELIST = ['http://frontend-IP:3000'] and in my frontend package.json I have: "proxy": "http://backend-IP:80", to tunnel the API to the backend so my axios commands look like: axios .get("/api/todos/") Rather than the whole address. I also am not sure how to make React use something other than localhost:3000 or if i need to change that if … -
How to render Markdownx content as HTML in a Django blog project?
I did all the installation of markdownx steps as stated. I've installed the django-markdownx package using pip install django-markdownx. I've added 'markdownx' to my INSTALLED_APPS in settings.py.

Django - Cannot make a celery worker and test transactions on test file without "You can't execute queries until the end of the 'atomic' block." error
Soo, here's the deal, Im creating a test in order to check if an improvement a made for performance is working or not, the improvements consists in making some signals logic an async task instead of an async process, I wanted to test this out but when I manually create a celery worker I get the django.db.transaction.TransactionManagementError: An error occurred in the current transaction. You can't execute queries until the end of the 'atomic' block. To have more context.. I'm avoiding creating a worker from the start because the pipeline does not use redis by default, or at least it avoids the celery creation, so I need to make one manually, but when I create the service I get the error def test_delete_optimal_deletion_time(self): """ Verifies that the `deletion logic` is under an acceptable running time. :return: """ # ... non-relevant code # Start Celery worker in a separate context to avoid nested atomic transactions with start_worker(celery_app, perform_ping_check=False): data_delete_start = time.time() og_org.delete() data_delete_end = time.time() data_total_test_end = time.time() data_total_test_time = data_total_test_end - data_total_test_start data_delete_time = data_delete_end - data_delete_start print("time to create test data: ", data_creation_time) print("time to delete test data: ", data_delete_time) print("time to run all test data: ", data_total_test_time) print("settings.CELERY_TASK_ALWAYS_EAGER: … -
How to test Django models against a DB without manage.py in a standalone package using pytest and GitHub Actions?
Context: I am developing a standalone Django package that is intended to be added to existing Django projects. This package includes Django models with methods that interact directly with a database. I want to write tests for these methods using pytest and pytest-django. I need to run these tests in a CI/CD environment, specifically using GitHub Actions. Problems Encountered: Database Setup: Since this is a standalone package, it does not include a manage.py file. This makes it challenging to run typical Django management commands like migrate to set up the database schema for testing. Table Creation: I encounter errors indicating that the table for my model does not exist because the necessary migrations are not applied. This is problematic because my tests need to interact with the database tables directly. Fixtures and Setup: I need to ensure the database tables are created and populated with initial data before the tests run. My attempts to use pytest fixtures and manually create database tables within the tests have not been successful. What I've Tried: Using pytest fixtures to set up the initial database state. Manually creating database tables within the test setup using direct SQL execution. Using the mixer library to populate … -

For my website- I implemented a profile pic you can add to your profile which works: models.py class Profileuser(models.Model): owner = models.OneToOneField(User, on_delete=models.CASCADE) name = models.CharField(max_length=50) tagline = models.CharField(max_length=100) bio = models.TextField(blank=True) website = models.URLField(blank=True) profile_pic = models.ImageField(upload_to="profiles/", blank=True) def __str__(self): return f"{self.id} | {self.name}" views.py class ProfileuserCreateView(LoginRequiredMixin, CreateView): model = Profileuser fields = ['name', 'profile_pic', 'tagline', 'bio', 'website'] success_url = reverse_lazy('recipes-home') def form_valid(self, form): form.instance.owner = self.request.user return super(ProfileuserCreateView, self).form_valid(form) Urls.py if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) However- when I tried to implement adding photos to my recipe posts- the images just don't upload, I can see the folder sitting empty models.py class Recipe(models.Model): title = models.CharField(max_length=100) recipe_image = models.ImageField(upload_to="imagerecipes/", blank=True) ingredients = models.TextField() description = models.TextField() author = models.ForeignKey(User, on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def get_absolute_url(self): return reverse('recipes-detail', kwargs={"pk": self.pk}) def __str__(self): return self.title views.py class RecipeCreateView(LoginRequiredMixin, CreateView): model = models.Recipe fields = ['title', 'recipe_image', 'ingredients', 'description'] def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) I don't understand why one works but the other doesn't as the code is virtually the same- if I upload via admin- it does work, I have also tested profile pictures and it still allows me to upload them.

How to Avoid Duplicate Validation When Creating Django Model Instances Manually and via Forms?
I’m new to Django and I need some help with model validation. Here’s what I’m trying to figure out: When I create new instances using forms, I know that calling is_valid on the form automatically runs the full_clean method for validation. After that, I just call save on the form. But when I create new instances manually, I need to call full_clean manually before calling save. I saw online that some people suggest overriding the save method in the model to ensure custom validation always runs, like this: def save(self, *args, **kwargs): self.full_clean() super().save(*args, **kwargs) This works fine when I’m creating instances manually, but it seems to call full_clean twice when I use forms (once during is_valid and once during save). This feels redundant and probably not efficient. My Question: What’s the best way to make sure my custom validation runs in Django models both when creating instances manually and via forms, without calling full_clean twice? Any advice or best practices would be really appreciated! Thanks a lot! -

Why is my AWS EC2 instance Supervisor failing?
I'm deploying a Django API I've named "ScientistBirthYear" to AWS EC2 following these instructions, including using the gunicorn.conf code, but modifying it to account for my virtual environment's name, project name, and X.wsgi:application from my project. At 24:50, the presenter's instance shows gunicorn running, where mine has failed multiple times. I've come across several solutions online, and none of them have worked. Here's the last several entries of my /var/log/supervisor/supervisord.log: 2024-07-16 22:56:07,174 INFO spawned: 'gunicorn' with pid 1861 2024-07-16 22:56:07,281 WARN exited: gunicorn (exit status 0; not expected) 2024-07-16 22:56:09,284 INFO spawned: 'gunicorn' with pid 1866 2024-07-16 22:56:09,391 WARN exited: gunicorn (exit status 0; not expected) 2024-07-16 22:56:12,396 INFO spawned: 'gunicorn' with pid 1871 2024-07-16 22:56:12,502 WARN exited: gunicorn (exit status 0; not expected) 2024-07-16 22:56:12,503 INFO gave up: gunicorn entered FATAL state, too many start retries too quickly 2024-07-16 22:56:25,588 CRIT Supervisor is running as root.
