Malloc: double free error on M3 Macbook pro
I am working on a Django python project with a postgres db hosted with render.com. The code works fine on server and my imac. I recently got a Macbook Pro M3 (running sonoma). I have replicated the exact same setup and environment however when I try to run the code locally, I get Python(40505,0x1704f7000) malloc: double free for ptr 0x1368be800 Python(40505,0x1704f7000) malloc: *** set a breakpoint in malloc_error_break to debug The setup is the exact same on the other device and it works fine there. Here is the link to repo https://github.com/moreshk/django-postgres Any assistance would be useful. Setup https://github.com/moreshk/django-postgres on my new device. Setup virtual environment, any dependencies and installed requirements and .env file. Would have expected it to run fine locally. Other Django Python projects seem to work fine, except this one which has a postgres db with render.com When I try to run the code locally, I get the below error: python manage.py runserver Watching for file changes with StatReloader Performing system checks...

Is there an easy way to suppress ResourceWarning when running tests -Wd
Is there a way on the Python or Django command line to suppress ResourceWarning when running tests with python -Wd i.e. python -Wd ./manage.py test ... A bunch of my tests don't close files, which is no problem because the test class instance which opened them goes away and that closes the file. I don't want to spend time editing all the tests. But fishing through the ResourceWarnings for the DeprecationWarnings is rather painful. -

How to save recorded video file to my filesystem with Javascript and Django?

Multithreaded Script Does not Increment Order Number Properly for a Django Database Entry
I have an images endpoint like this: /api/properties/image/ and I can post an image to the endpoint, and that saves an image link to the Postgres database. This line of code handles the logic: def create(self, validated_data): property_id = self.context['property_ad_id'] # This line handles the update order = PropertyImage.objects.filter(ad_id=property_id).count() + 1 return PropertyImage.objects.create(ad_id=property_id, order=order, **validated_data) From the above, it counts how many images are currently in the database, stores it in memory then increments it by one, and finally, it creates a new image with that incremented value as its order. The operation works as intended until I use a multithreaded script as the one below to mass-populate the images: def single_property_upload(image_file, property_id): BASE_URL_PROPERTY = base(property_id=property_id) with image_file.open(mode="rb") as f: image_data = f.read() files_data = {"image": ("image.jpg", image_data, "image/jpeg")} response = requests.post(BASE_URL_PROPERTY, files=files_data) def post_images(image_files, id): threads = [] for image_file in image_files: # Create a new thread for each image upload t = threading.Thread(target=single_property_upload, args=(image_file, id)) t.start() threads.append(t) # Wait for all threads to complete for t in threads: t.join() def populate_images(): for i in range(1, 1001): image_files = [ Path.cwd() / "house_images2" / f"{str(randint(1, 160))}.jpg" for i in range(4) ] post_images(image_files, str(i)) print(f"Property {i} populated successfully") print("Done") populate_images() … -
Solving the Django Testing Puzzle: Incorporating JWT Tokens in Authorization for POST
I'm encountering an issue while testing a Django REST Framework endpoint that requires authentication and authorization using the IsAdminUser permission class. The endpoint is designed to handle POST requests, and it checks if the authenticated user has the is_admin attribute set to True. Here's a simplified version of the endpoint code: class MyView(APIView): permission_classes = (IsAdminUser,) def post(self, request): master = request.user if master.is_admin: name = request.data['name'] I have written a test case to simulate a POST request to this endpoint, and I'm encountering the error 'AnonymousUser' object has no attribute 'is_admin' when I run the test case with the following code: class MyViewTestCase(TestCase): def setUp(self): self.client = APIClient() token = '{jwt_token}' client.credentials(HTTP_AUTHORIZATION="token " + token) self.valid_data = {"name": "A", "at": "11", "d": "11"} def test_valid_request(self): client = APIClient() response = client.post('/endpoint', self.valid_data, format='json') I have confirmed that the endpoint works correctly when tested with an authorization token in Postman. How can I properly authenticate the user in my test case to avoid this error and successfully test the authenticated endpoint? Any insights or examples on how to structure the test case for a token-authenticated POST request with the IsAdminUser permission would be greatly appreciated! -
Error Encountered When Pushing Code with Azure AD (MSAL) Integration to Azure Web App Using GitHub
I have a Django project with a built-in authentication system that works fine in both development (dev), system integration testing (SIT), and production (PROD) environments. After implementing Azure AD integration and starting the server with "sslserver," everything works fine because Django runs on HTTPS. However, when I push the code to the production environment, I encounter an error: "Application error." I encountered multiple issues during the implementation: When running the Django server using "runserver," I encountered an error: AADSTS50011: The redirect URI 'http://domain.azurewebsites.net/auth/redirect' specified in the request does not match the redirect URIs configured for the application. I identified this problem when using the sign-in feature, as it failed to authenticate and pick up the correct redirect URI. After changing the redirect URI from HTTP to HTTPS, the sign-in authentication was successful. However, when Azure AD sent a response to the Django app, another error occurred: You are trying to access "http://domain.azurewebsites.net/auth/redirect," but the return URI is "http://domain.azurewebsites.net/auth/redirect."

Django migrations does not apply in production

Pass variable through HttpResponse | Django
I have the following code working properly to download a file @ Django: def download_file(request): response = HttpResponse(Document2.file, content_type='application/force-download') response['Content-Disposition'] = f'attachment; filename="sigma.xlsx"' return response My goal: after the user has downloaded the file, in other words, the def download_file has been runned, I need to show the form in the template page. <h2><i class="fa fa-cog"></i></h2> <h1>Upload base de dados</h1> <p>Antes de realizar o upload da nova base de dados, realize, por medidas de segurança, <span class="detail-color">o download</span> do atual banco de dados.</p> <br> <a href="{% url 'auditoria_app:download_file' %}" class="" style="color: red">Clique aqui para baixar o arquivo atual.</a> **{% if variable = 'yes' %}** <form id="" action="{% url 'auditoria_app:upload' %}" method="POST" class="" enctype="multipart/form-data"> {% csrf_token %} <label for="test"> <section><i class="fas fa-cloud-upload-alt fa-3x"></i> Clique aqui ou arraste a base de dados para essa área!</section> {{ form.as_p }} </label> <p id="filename"></p> <button type="submit" class="button-section-1" onclick="disable()" value="Save"> Iniciar upload </button> </form> **{% endif %}** As a precautionary measure, I would like the user to download the file before uploading a new one. Hence the reason for rendering the page only after the download has been completed. How can I solve this? Tks!
