I have a Django web app that relies heavily on third-party data. How to make the two sides independent but still usable?
I am building a web app using Django, but I have some doubts about the best architecture. The real-life scenario is more complex, but - for the sake of keeping it simple - let's use the example of a Fantasy Football app. There are two sides: the Football data (Matches, Clubs, Players, etc.) that comes from a third party API the Game data (Users, Fantasy leagues, Fantasy teams, etc.) that is generated inside the web app My first thought is that the Football data should be handled outside Django, for example having my ETL/ELT pipeline in phython scripts (e.g. using Polars) orchestrated using Airflow. In the real-life scenario there may be multiple sources, and the data could also be used for other purposes (e.g. analytics), so I think it would be best to keep it in a separate db that acts as my data warehouse. Also, this would make it so that the ETL process won't take away resources from the web app (although I guess I could achieve the same with e.g. Celery), and that I can keep my codebase separate. Question 1: Does this make sense? Second, I have the web app. I suppose that to use Football … -
Override Easy Thumbnails Dango File Type Setting
While using easy thumbnails in Dango I have set the default file type to webp. It works well. But on occasion I need it to ignore this setting. For example when I render an og image I would like it to stay as a PNG. Would it be possible to add an option to the template tag to use the default uploaded format and ignore the setting in the settings file? How would I code it, I'm guessing it would be some sort of override to the standard template tag or a new template tag that adds to the old template tag and calls it maybe. -
Django error "TemplateDoesNotExist" despite template existing

Database Connection Issue with Django createsuperuser Command
Getting a strange error when configuring Django. I have configured the database with host 0.0.0.0 in settings.py: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'xx', 'USER': 'xx', 'PASSWORD': 'xx', 'HOST': '0.0.0.0', 'PORT': '3306', } } When I do the migration python manage.py migrate it uses this host and account and sets the tables up. When I try to set up the superuser python manage.py createsuperuser I get a connectivity error: django.db.utils.OperationalError: (1045, "Access denied for user 'websiteuser'@'localhost' (using password: YES)") I'm not sure why this is trying to connect to localhost rather than the host in the settings file. Is there another settings file I've missed or do I need to provide a flag? -
Why do elements literally jump outside of their parents?
On this specific screen of an app I'm building, elements seem to and actually do escape their parent. I'm using Django, TailwindCSS and AlpineJS. But after some testing it's clear the problem doesn't belong to any of these frameworks. On the back-end, I'm looping over an array to render the courses inside a <section> inside <main>. The first one obeys fine. The second jumps to the div above main and the third goes all the way under <body> After removing both links to CSS and JS, the problem remains: So the problem isn't in either Tailwind or Alpine. So I checked the page sources, which are fine! The way they should be: I tested on Firefox Nightly, Edge and Brave, and they all behave the same. The loop in specif that is being run is this: {% for course in courses %} <div class="rounded-2xl bg-gray-100 shadow"> <header class="flex justify-between px-6 py-4" x-data="{ optOpen: false }" > <div> <h2>{{ course.name }}</h2> <span>Turno: {{ course.get_time_display }}</span> </div> <div> <button> <svg ...>...</svg> </button> <button @click="optOpen = !optOpen" class="relative"> <svg ...>...</svg> <div x-show="optOpen" class="absolute flex flex-col"> <button>Editar</button> <button>Excluir</button> </div> </button> </div> </header> <div>whats happening??</div> </div> {% endfor %} I don't know what else to … -

Is it bad to run a fake initial migration during deployment? (Django)
When deploying my Django project, I kept getting this error: W: psycopg2.errors.DuplicateTable: relation "materials_location" already exists W: The above exception was the direct cause of the following exception: --snip-- W: django.db.utils.ProgrammingError: relation "materials_location" already exists While the problem seems self-explanatory, this error first started appearing after I manually altered the database when I had to rename apps and move models around apps. ("materials_location" was one of the things I'd added.) I eventually found this solution: running python manage.py migrate --fake-initial during the deploy hook (instead of just python manage.py migrate). This allowed Django... ...to skip an app’s initial migration if all database tables with the names of all models created by all CreateModel operations in that migration already exist. Problem solved. The rest of the migration was applied correctly (which included the addition of fields to the existing models) and the project was deployed without any errors. Is there a scenario where this solution could backfire down the line? Like, what if I deploy to a new server and make a brand new database? Or if I reset or squash migrations? I feel like this is safe, but straying from python manage.py migrate makes me uneasy. -

How to filter a Django model by properties of a reverse foreign key
I need to filter a Django model based on properties of a reverse foreign key and I'm not sure of the best way to do this. I have two models in which Products belong to a ProductRange class ProductRange(models.Model): pass class Product(models.Model): product_range = models.ForeignKey(ProductRange, related_name="products") is_archived = models.BooleanField() Product Ranges in which all products are set is_archived=True are to be considered archived, if any products are not marked as archived they are not considered archived. I need a way to filter Product Ranges based on this, i.e a filter that returns product ranges for which all products are archived. I'm aware I can filter by the related name: ProductRange.objects.filter(products__is_archived=False) However this returns product ranges where Any product is archived no all products. I'm also aware I can do the filtering in Python but I need this filter work on a large dataset and I'm sure there is a more efficient way to do this in the database. I've also considered using models.Subquery or models.Exists, however I feel like there is probably a simpler and more performant way of doing this that I am missing, also this would require a lot of refactoring to avoid a circular import. I feel … -

AttributeError: 'WSGIRequest' object has no attribute 'tenant'
I'm using django-tenants, following the Installation Guide, and I've created a simple project. Here's the scenario: I have a model named UnVerifiedTenants that stores company data, including their email and tenant ID. class UnVerifiedTenants(models.Model): """ model that Saves user email, depending upon below points 1. all emails from tenants for proper tenant utilization 2. all emails who just enquired and did not proceed further """ tenant = models.ForeignKey(Tenant, on_delete=models.CASCADE, null=True, blank=True) email = models.EmailField(verbose_name="Email Address", unique=True) admin = models.BooleanField("Is user admin", default=False) created_on = models.DateField(auto_now_add=True) updated_on = models.DateField(auto_now=True) When users create their accounts on the registration page, the data is stored in this model. After users verify their phone number (which is stored in a different table), I migrate their schema. After completing the migration, they enter their email on the login page. I check their email, retrieve their schema, and create a URL to redirect them to their tenant domain for further authentication: class Login(generic.TemplateView): form_class = InitialAuthenticationForm template_name = "login.html" def post(self, request, **kwargs): email = request.POST["email"] scheme = "https" if self.request.is_secure() else "http" domain = settings.DOMAIN shared_user = AllUsersEmails.objects.filter(email=email).first() if shared_user: tenant_obj = shared_user.tenant try: tenant = tenant_obj.schema_name sub_url = f"accounts/enter-password/{encrypt(email.encode()).decode()}" url = f"{scheme}://{tenant}.{domain}/{sub_url}" shared_user.update_last_login() return redirect(url) …
