Which Django model relationship is appropriate?
Let's say I create a Profile extending the Django User Model, each time a new user is created. And I want to store multiple items in a field, for example, 10 track names in the track name field for a particular user, in the Profile(will differ from user to user). Which model relationship can help achieve this? Or do I create a new model for songs, named preferably "songs", and use a model relationship to Profile? What is the best way to do this? models.py class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) track_name = models.CharField(on_delete= models.CASCADE , related_name="track") artiste_name= models.CharField(on_delete=models.CASCADE , related_name="artiste") album_name = models.CharField(on_delete= models.CASCADE, related_name= "album") class Meta: db_table = "Profile" def __str__(self): return self.track_name -

Data transfer from one HTML page to another
When creating a technical site, I faced the need to transfer data and save it in a file. I am making a website in Django. In models I create input data. I receive these data in HTML and, if necessary, the user changes them and JS performs the necessary calculations, the results of which are sent to the same page. It is possible to do a lot of analytical work on outgoing data (build graphs, calculate a loan, calculate various project risks). I prefer to create several pages so as not to fill one. All pages have already been built. There was a problem of this nature: On the main page, JS did his job but I do not know how to access this data on other pages. Is there a solution to write a JSON string to a file or send them to Django model (update static data). I read a lot and looked for solutions, but I could not figure it out until the end. Maybe someone knows the solution. Thank you in advance. If need more information, please let me know. This is my first request for help, so please don’t be strict if I cannot ask … -
Django dynamic filtered ListView returning error: get() got multiple values for argument 'self'

Django returning form error but the input seems to be valid
One of my models is a Product model which has 3 different price fields, so that one of its prices can be chosen when creating an order. I created a select input in one of my forms to allow the user to choose one of the prices, but when the form is submitted, Django returns an error telling me to introduce a valid number, even though I checked the request.POST and the value it's sending is a valid number. models.py: class Product(models.Model): ... price_1 = models.DecimalField(max_digits=10, decimal_places=2, null=True, blank=True, default=0) # Separador de miles price_2 = models.DecimalField(max_digits=10, decimal_places=2, null=True, blank=True, default=0) # Separador de miles price_3 = models.DecimalField(max_digits=10, decimal_places=2, null=True, blank=True, default=0) # Separador de miles forms.py: class CartAddProductForm(forms.Form): price = forms.DecimalField() quantity = forms.IntegerField( label ='Amount' ) override = forms.BooleanField(required=False, initial=False, widget=forms.HiddenInput) views.py: @require_POST def cart_add(request, product_id): cart = Cart(request) product = get_object_or_404(Product, id=product_id) form = CartAddProductForm(request.POST) if form.is_valid(): cd = form.cleaned_data cart.add(product=product, quantity=cd['quantity'], price=cd['price'], override_quantity=cd['override']) return redirect('cart:cart_detail') Template: <form action="{% url 'cart:cart_add' product.id %}" method="post"> {% csrf_token %} <div class="form-group"> <label for="id_price">Precio</label> <select name="price" id="id_price" class="select2 form-control" data-toggle="select2" required> <option value="{{ product.price_1 }}" selected>Precio retail: ${{ product.price_1|intcomma }}</option> {% if product.price_2 %} <option value="{{ product.price_2 }}">Precio mayorista: ${{ … -

Python / Django connection timeout for database or memcached or other connections
I`m setting up a django Server in AWS. Securitygroups are used to configure the connections between the services. When such a securitygroup is closed, there is just a never ending timeout. Example: Django should connect to a database server https://myvp.aws.com/whatever:5432, and the securitygroup denies that, then django just does nothing until the request is canceled by nginx (60s) per default. I would like to tell django/python to stop after 5 seconds, and show me a explicit connection error, so that I can debug that. Where could I set this? In Python? In Django? On my Alpine? Any ideas? -

Issue reworking the djangocms language chooser as a location chooser
I have a djangocms website with a location chooser built on top of the language switcher (each location only has one language available). The site has 4 countries that are covered by location-specific content. An IP check redirects visitors from those countries to their country-prefixed URL. A visitor not in one of those countries lands on a the global version, with no country prefix. Example: visitor goes to example.com visitor is in US: example.com/us visitor is in CA: example.com If the site visitor wants to override their IP-assigned country choice, they select one of the other locations from a drop-down in the navigation. Example: visitor goes to example.com visitor is in US: example.com/us visitor chooses to view site as if they are in Belgium: example.com/bl The problem I have is that anyone in one of the covered locations can't choose the default, global choice. Example: visitor is in US: example.com/us visitor chooses global view: should be example.com, but they're redirected to example.com/us This is happening because the context processor I have (see below) checks if the user's request.LANGUAGE_CODE is 'en', which it is when they first come to the site (default in settings.py) and when they choose "global" (the language … -
