inconsistent django session key
I am implementing a cart function which gets session key since it doesnt have user login. But every time I add something to the cart, it gets different session key. When I check the django admin panel, it adds data to the cart but I get an empty array whenever I call my Get Cart api. @api_view(['POST']) def add_to_cart(request): try: session_key = request.session.session_key if not session_key: request.session.create() session_key = request.session.session_key product_id = request.data.get('product') quantity = request.data.get('quantity') size_id = request.data.get('size') if not all([product_id, quantity, size_id]): return Response({'error': 'Missing required fields'}, status=status.HTTP_400_BAD_REQUEST) cart_item = Cart.objects.create( product_id=product_id, quantity=quantity, size_id=size_id, session_key=session_key ) serializer = CartSerializer(cart_item) return Response(serializer.data, status=status.HTTP_201_CREATED) except Exception as e: return Response({'error': str(e)}, status=status.HTTP_500_INTERNAL_SERVER_ERROR) @api_view(['GET']) def get_cart_items(request): session_key = request.session.session_key cart_items = Cart.objects.filter(session_key=session_key) serializer = CartSerializer(cart_items, many=True) return Response(serializer.data) -

Will a dynamic list of choices in a Django model evaluate when the model is migrated or when a user tries to select a choice for a model?
Code Let's say I have the following model: class Course(models.Model): title = models.CharField(max_length=48) YEAR_CHOICES = [(r, r) for r in range( datetime.date.today().year-1, datetime.date.today().year+2 ) ] year = models.IntegerField(_('year'), choices=YEAR_CHOICES) Question Will the datetime.date.today() statements be evaluated right when the model is migrated, or will they be evaluated whenever the user accesses a form to set the year value for the Course model? In other words, is my YEAR_CHOICES code above frozen to when I migrated my model or will it dynamically update as the years go by? -
django generic UpdateView with some custom fields
My question is quite close to this one UpdateView with additionnals fields, so I used the info, but I still lack some details to complete the process So, I have a simple toy model : class TxtPlus(models.Model): txt = models.CharField(max_length=140) def __str__(self): return f'TxtPlus<{self.id},{self.txt}>' def get_absolute_url(self): return reverse("tplus_detail", kwargs={"pk": self.pk}) When editing an instance, I want to add a field, and thus according to the answer above, I define a custom Model class TxtPlusForm(ModelForm): info = CharField(widget=Textarea(attrs={"rows":"2"})) class Meta: model = TxtPlus fields = ["txt", ] the using the UpdateView is easy class TxtPlusUpdateView(UpdateView): model = TxtPlus template_name = "adding_to_model_forms/tplus_update.html" form_class = TxtPlusForm But, what I wish to do is roughly: def infos_associated_to_object(object): return f'there is more about object:{object.pk}' def test_edit(request,pk): object = TxtPlus.objects.get(id=pk) info = infos_associated_to_object(object) if request.method == 'GET': form = TxtPlusForm(instance=object,initial={'info': info}) up_log = None if request.method == 'POST': form = TxtPlusForm(request.POST,instance=object) up_log = f"change '{info}' to '{form.data['info']}'" form.save() #... add here form.data['info'] saving return render( request, "adding_to_model_forms/tplus_edit.html", { "object" : object, "form" : form, "info" : info, "up_log" : up_log } ) (of course, infos_associated_to_object, is here a toy version..)

Images not showing, using Django admin, cloudinary and deploying to Heroku
I'm trying to add images to my project (in the albums) using django admin, cloudinary and then it is being deployed to Heroku. I can't seem to make it work, sat with a tutor for 2 hours yesterday and we made it work and now it's just gone again. Header image is just black and the image for the album is coming back as a 404 even if I checked that the image is where it should be. When I upload on Django admin the image file does not go to the workspace and stays in cloudinary so I think it is because of that. Anyone who has any other ideas? enter image description here Where it's black shoul be a static image and further down where the image icon is should be an image loaded from Django admin panel. -

Django migration keeps generating old model attributes (is it cached somewhere?)
I am new to Django but have some experience with MVC web development. I am encountered with a weird problem, hopefully, it is only weird to me, not all folks. After doing some changes (changing attribute's names) in models project_name/models.py. I ran: python manage.py makemigrations to migrate the DB with new changes. But it showed that "No changes." So I decided to do a fresh re-migrate DB :( Delete DB and recreate empty DB Delete migrations/ folder and recreate folder with __init__.py Re-run makemigrations OK. Now the weird thing happens. No matter how I change in models.py, the migrations/0001_initial.py file always keep generate old attribute. # models.py class Task(models.Model): STATUS_CHOICES = [ ('PENDING', 'Pending'), ('PROCESSING', 'Processing'), ('COMPLETED', 'Completed'), ('FAILED', 'Failed'), ] pdf_file = models.FileField(upload_to='pdfs/') status = models.CharField(max_length=10, choices=STATUS_CHOICES, default='PENDING') #Previously `preview_url` preview_img = models.ImageField(blank=True, null=True, upload_to='previews/') #Previously `thumbnail_url` thumbnail_img = models.ImageField(blank=True, null=True, upload_to='thumbnails/') error_message = models.TextField(blank=True, null=True) uploaded_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return f"Task: {self.id} - {self.status}: {self.pdf_file.name}" # migrations/0001_initial.py ... operations = [ migrations.CreateModel( name='Task', fields=[ ('id', models.BigAutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('pdf_file', models.FileField(upload_to='uploads/')), ('status', models.CharField(choices=[('PENDING', 'Pending'), ('PROCESSING', 'Processing'), ('COMPLETED', 'Completed'), ('FAILED', 'Failed')], default='PENDING', max_length=10)), ('preview_url', models.URLField(blank=True, null=True)), # WEIRD ('thumbnail_url', models.URLField(blank=True, null=True)), # WEIRD ('error_message', models.TextField(blank=True, … -

Adding Custom Description Input Field Next to File Names in FilePond
I'm using FilePond for file uploads in my Django project. I want to add a custom description input field next to each file name in the list of files to be uploaded.

Converting Django PWA to iOS and Android Apps Using Capacitor: Handling Django Templates and Offline Support
I have a web application developed using Django and Django PWA. The application uses Django templates to render HTML with context passed from the views. I am considering converting this web application into a mobile application for both iOS and Android using Capacitor. I have a few questions and concerns about this process: Django Templates and Context: Will the context passed to Django templates work correctly when the application is converted to a mobile app using Capacitor? Are there any specific considerations or adjustments needed to ensure smooth operation? Offline Support: Given that Django templates are rendered server-side, will the application encounter issues when accessed offline in the mobile app? How can I implement offline support effectively in this scenario? Best Practices for Conversion: What are the best practices for converting a Django web application to mobile apps for both Android and iOS? Are there any recommended tools or frameworks that could facilitate this process more efficiently? I would appreciate any insights, experiences, or suggestions from those who have undertaken similar conversions. Thank you in advance for your help! -

Website shows Server error 500. Suspect it's SSL releated
My site was working just fine, and then it stopped for reasons I don’t know. I get a Server Error 500. I believe it’s related to SSL, because in most browsers I get that error, but in Brave it goes to http and works fine (as http). My site log lists no errors, and I don’t see any in the apache logs either. The relevant settings.py: secure proxy SSL header and secure cookies SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') SESSION_COOKIE_SECURE = True CSRF_COOKIE_SECURE = True session expire at browser close SESSION_EXPIRE_AT_BROWSER_CLOSE = True wsgi scheme os.environ['wsgi.url_scheme'] = 'https' and wsgi.py: os.environ['HTTPS'] = "on" and in my apache 000-default_ssl.conf: SSL section SSLEngine on SSLCertificateFile /etc/ssl/certs/mysite.crt SSLCertificateKeyFile /etc/ssl/private/mysite.key and lastly, in the 000-default.conf I have: RewriteEngine On RewriteCond %{SERVER_PORT} !^443$ RewriteRule ^(.*)$ https://%{HTTP_HOST}$1 [R=301,L] I could really use some help. Thanks. I checked the site log, and the apache logs. There's no evidence of errors. I only suspect it's an SSL problem because it oddly works in a Brave browser and not others. -
Separate database for each user in web app
I’m creating a web app. I need to give each user a separate database. I know this isn’t seen as a great practice and a single database is usually used in these scenarios, but for this project this is the way it needs to be. I have a current working solution in Django. However, my current solution means that if the customer was ever to delete one of their users and add a new one I would have to rebuild and deploy the project to them. Also to clarify, the web app will be deployed on a per customer basis on their own server so this isn’t really a multitenant solution I’m looking for. Would this be easier in flask? This is my first time using django or web apps in general so I'm still learning a lot. My current solution in Django involves routing requests to a specific database based on the user’s credentials. The database names are still defined in settings.py before deployment and named after the some form of user credentials like an id or email. But like I mentioned, there are lots of cases where I would have to reconfigure the databases in settings.py and redeploy …
