Issue uploading files to S3 in Django on Azure App Services
Our application has been hosted on Heroku for several years without any issues uploading to S3. We are working on migrating to Azure App Services. We are now encountering an issue where the the file uploads are failing. They appear to be timing out and cause the gunicorn worker to abort and close. The server log and stack trace hasn't been helpful, but I'm hoping someone else may see something here that can be useful. None of the storage configuration or settings have been modified from Heroku to Azure. packages being used: Django==3.2.25 boto3==1.35.9 botocore==1.35.9 s3transfer==0.10.2 django-storages==1.14.4 Settings: DEFAULT_FILE_STORAGE = 'project.utils.storage.HashedFilenameMediaS3Boto3Storage' Storage class - this storage class setup was implemented about 8 years ago so maybe I need to make some changes?: def HashedFilenameMetaStorage(storage_class): class HashedFilenameStorage(storage_class): def __init__(self, *args, **kwargs): # Try to tell storage_class not to uniquify filenames. # This class will be the one that uniquifies. try: new_kwargs = dict(kwargs) #, uniquify_names=False) super(HashedFilenameStorage, self).__init__(*args, **new_kwargs) except TypeError: super(HashedFilenameStorage, self).__init__(*args, **kwargs) def get_available_name(self, name): raise NoAvailableName() def _get_content_name(self, name, content, chunk_size=None): dir_name, file_name = os.path.split(name) file_ext = os.path.splitext(file_name)[1] file_root = self._compute_hash(content=content, chunk_size=chunk_size) # file_ext includes the dot. out = os.path.join(dir_name, file_root + file_ext) return out def _compute_hash(self, content, chunk_size=None): … -
How to Resolve the Issue: Django with Visual Studio Code Changing Template Without Effect?
I have a Django app, and I am using Visual Studio Code as my editor. I have implemented functionality for recovering passwords via an email template. I edited the template to see what effect it would have on the email, but the changes had no effect. I even deleted the email template, but I still received the old email template in my inbox. The email template is within a folder named templates in my account app. Here is my email template (password_reset_email.html): <!-- templates/password_reset_email.html --> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Password Reset Request</title> <style> /* Add any styles you want for your email */ </style> </head> <body> <p>Je hebt om een wachtwoord reset aanvraag gevraagd voor je account.</p><br><p> Klik de link beneden om je wachtwoord te veranderen:</p> <p>Als je niet om een wachtwoord reset hebt gevraag, neem dan contact op met:</p> <br><p> test@test.nl.

Django formtools' "done" method is not getting called on form submission
I am trying to build a multistep html form using Django formtools. I have 2 forms with 2 fields at most. After filling the last form (i.e. step 2) and clicking the submit button, I am taken back to step 1 instead of the "done" method being called. And the whole thing just becomes a never ending loop.

Django filtering by annotated field
I'm trying to sort only those objects that contain arrays in the JSON field class Rule(models.Model): data = models.JSONField() class JsonbTypeof(Func): function = 'jsonb_typeof' Rule.objects.annotate(type=JsonbTypeof("data")).filter(type="array") But this query always returns an empty queryset However, if you call Rule.objects.annotate(type=JsonbTypeof("data")).values("type") then the expected queryset with a set of objects is returned: <QuerySet [{'type': 'object'}, {'type': 'object'}, {'type': 'array'}, {'type': 'array'}]> And if you do like this: Rule.objects.annotate(type=Value("array")).filter(type="array") Then the filtering is done correctly Are there any experts who can tell me how to filter and leave only arrays? -
Auto-generated DRF route *-detail not found while using ViewSets
I try to use Django Rest Framework (DRF) with HyperlinkedModelSerializers, ViewSets and a Routers. When I check the generated routes, Django shows me vehicle-detail, but DRF complains with an error: ImproperlyConfigured at /api/vehicles/ Could not resolve URL for hyperlinked relationship using view name "vehicle-detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field. The code below works well if a leave out the url from fields. Anyone an idea what is missing? urls.py from rest_framework.routers import DefaultRouter from vehicles import viewsets # Create a router and register our ViewSets with it. router = DefaultRouter() router.register(r'vehicles', viewsets.VehicleViewSet, basename='vehicle') # The API URLs are now determined automatically by the router. urlpatterns = [ path('', include(router.urls)), ] vehicles/viewsets.py class VehicleViewSet(viewsets.ModelViewSet): queryset = Vehicle.objects.all() serializer_class = VehicleSerializer vehicles/serializers.py class VehicleSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Vehicle fields = ['url', 'name', 'description'] # fields = ['name', 'description'] # Removed 'url'.

How to do Markdown-like custom text to HTML formatting in Django?
My aim is to get text input, pass it through regex to turn it into HTML tags, and then safely display that HTML. Something like this: It's <script> *Bold*...! @sysop! which becomes, rendered faithfully, It's &lt;script&gt; <span class="f-b">Bold</span>...! @<a class="f-at" href="/user/123">sysop</a>! (It doesn't have to be exactly this, this is just an example.) Note that my output is able to grab values like the user sysop and get the user instance's URL /user/123 from the database - a good solution should be free enough to allow things like this. What I'm looking for is not specifically Markdown. What I'm looking for is the ability to do custom regex filters as shown above. If there is a way to do this, or even a package that allows me to do that (and remove/disable the existing Markdown/BBCode/etc. filters), that would be really great. -
How to integerate Saleor in my Django project
I have an existing Django project that I've been working on, and I'm interested in integrating the Saleor dashboard as an app within this project. Ideally, I would like to access the Saleor dashboard through a route like backend/. Additionally, I want to connect the Saleor dashboard with my existing product database. I already have a fully responsive frontend built with HTML and CSS that displays products and other related information. My goal is to integrate all the features of Saleor, such as checkout, payment processing, and other e-commerce functionalities, into my current project without needing to start a new project. How can I achieve this integration while maintaining my existing frontend and backend structure? Any guidance or suggestions on how to approach this would be greatly appreciated! -

how to copy/paste blocks in wagtail(wagtail into existing django project)
i try to understand requirements and know the possible methods and the wagtail project is using wagtail-modeltranslation, here is the requirements: "Main purpose of this is to speed up making new pages, and the translation from EN to NL. Now, when we make a nice series of blocks in EN, we need to rebuild them all for the NL version, which is annoying.

How check if user is logged in on server side React, Django, JWT
I have set up authorization using the JWT token. Now I want to give the user access to the protected view, which requires authorization. class GetUser(APIView): authentication_classes = [JWTAuthentication] permission_classes = [IsAuthenticated] def post(self, request): return Response({'username': request.user.username}) How do I check if the user is logged in on the server side? I wrote an asynchronous function that accesses the django rest framework api. But this function always returns a promise no matter what I do. function saveToken(data) { localStorage.setItem('access_token', data.access) localStorage.setItem('refresh_token', data.refresh) return true } async function isLoggedIn() { return await axios.post('api/getuser/', {}, {headers: {Authorization: 'Bearer ' + localStorage.getItem('access_token')}}) .then(async function (response) { return true }) .catch(async function (error) { return await axios.post('api/token/refresh/', {refresh: localStorage.getItem('refresh_token')}) .then(async function (response) { return saveToken(response.data) }) .catch(async function (error) { return false }) }) } As I understand it, I can't get the value from promise in any way. That's why I decided to write the component this way, but React throws an error. const ComponentMainArea = () => { const location = useLocation() const element = useOutlet() return isLoggedIn().then((value) => { if (!value) { return (<Navigate to="/proxy/8000/login"/>) } else { return ( <div className='mainarea'> <AnimatePresence mode='wait' initial={true}> {element && React.cloneElement(element, { key: … -
https to http nginx works partially
I can use http and https connection to my router(to which connected server) through KeenDNS.

Btw I'm having Django in docker with gunicorn behind proxy_pass's web url. Over http everything works fine. What could be the problem? -
Supporting Apple sign-in for mobile and web using dj_rest_auth, allauth
We are looking to implement Apple sign-in from both the web and mobile using this stack. React SPA using Django 4.2 / DRF 3.15.2 / dj_rest_auth 6.0.0 / allauth 0.61.1 backend Due to the different Client ID for web and mobile, we had to configure two separate apps in SOCIALACCOUNT_PROVIDERS[”apple”] as recommended by allauth. To make this work for the version we are using, we had to manually apply the following patch to 0.61.1 and set the “hidden” property on the mobile app. My impression was that this property is needed to make it work with some admin interface, but maybe not. The explanation is not clear - “For the app specifying the bundle ID, add the following to the settings so that this app does not show up on the web”. We use the same settings for both APPS - secret, key, settings, except for client_id. When we set this property, the “hidden” app (mobile) never gets used and we get a client_id mismatch error when logging in from mobile. So I guess I am not sure I understand the purpose of having that property. Or maybe we are missing some other patch(es) that make this work. In short, … -
Memory Leak When Using Django Bulk Create

Theres a consistent, and unending memory leak. #1: postgresql\operations.py:322: 156.9 KiB return cursor.query.decode() #1: postgresql\operations.py:322: 235.3 KiB return cursor.query.decode() #1: postgresql\operations.py:322: 313.7 KiB return cursor.query.decode() #1: postgresql\operations.py:322: 392.0 KiB return cursor.query.decode() #1: postgresql\operations.py:322: 470.4 KiB return cursor.query.decode() I found this for someone using MySql https://stackoverflow.com/a/65098227/8521346 But im not sure how to even test/ fix this if it was the issue with the postgres client. -

ModuleNotFoundError: No module named, how come no model was named since it is written in the main code and in the model?
I created this model code but the django makemigrations command doesn't work and show an error. The first code is where the database should be and where I put the name of the model I want, the second code is how the model is made so far and the last is the error that appears when I try to use makemigrations. I have no idea what to do to make it work. ``INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'livros'` `from django.db import models class Livros(models.Model): nome = models.CharField(max_length = 100) autor = models.CharField(max_length = 30) co_autor = models.CharField(max_length = 30) data_cadastro = models.DateField() emprestado = models.BooleanField(default=False) nome_emprestado = models.CharField(max_length = 30) data_emprestimo = models.DateTimeField() data_devolução = models.DateTimeField() tempo_duração = models.DateField()` File "<frozen importlib._bootstrap>", line 1204, in _gcd_import File "<frozen importlib._bootstrap>", line 1176, in _find_and_load File "<frozen importlib._bootstrap>", line 1140, in _find_and_load_unlocked ModuleNotFoundError: No module named 'livros'
