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 … -
How to customize UI of Swagger (drf-yasg) to use dark mode?

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) … -
Django - large file upload - moving file from temp folder to final destination fails
Stumbled upon this error when upgrading Python, Django and Alpine to latest versions... and it's a weird one. The error occurs when I upload a file that is larger than FILE_UPLOAD_MAX_MEMORY_SIZE (set to 5MB). I have two development environments set up. One is local dev server (just normal py manage.py runserver), the other one is running under Docker(Windows) + Alpine linux + Apache2 + mod_wsgi which is also still a 'development' environment. This error occurs only under Docker environment and only when file exceeds max memory size. Under all other circumstances the upload works - even when file exceeds memory limit on local dev server.

Should I render dynamic charts in Django or serve them from another webapp?
Here is this Django webapp hosted in a Apache2 server with mod_wsgi My question is: How do I add dynamic graphs to my webapp? In producion, in order to serve files, Nginx reverse proxy server catches the urls with the /static/ subdomain and serves the content (otherwise the request is redirected to apache) Google returns planty of ways to address the matter. Do you have any recomandation or relatable experience that I should know before choosing any? My concerns are: How clients update graph data without refreshing the whole page ? (I currentlly use htmx for rendering html) Should I use a second webapp to serve the content to nginx redirect? Is django-plotly-dash the most straight way? Will it work with htmx or else? I tried to periodically render an html with a plotly graph using htmx; resulted awful -

Django: prevent Form to crash when akward date format is used
I have a form: class EditProfileForm(forms.ModelForm): template_name = 'users/edit_profile.html' def __init__(self, *args, **kwargs): super(EditProfileForm, self).__init__(*args, **kwargs) self.fields['email'].help_text = _( 'Providing your email would enable you to recover your lost password') class Meta: model = get_user_model() fields = ( 'first_name', 'last_name', 'email', 'birthday', 'language', 'headshot', ) with user model: class CustomUser(AbstractUser): birth_year = models.PositiveIntegerField( verbose_name=_('Birth year'), default=0) birthday = models.DateField(verbose_name=_( "birthday"), null=True, blank=True) headshot = models.ImageField(verbose_name=_('Avatar'), null=True, blank=True, default='user_headshots/user.png', upload_to="user_headshots/") language = models.CharField(verbose_name=_('Language'), max_length=10, choices=settings.LANGUAGES, default=settings.LANGUAGE_CODE) I had a user use a strange format for birthday "25,2,96", which led the django application to crash: The view users.views.edit_user_profile didn't return an HttpResponse object. It returned None instead. not much more information in the Traceback !?! Looking into the django code and internet, I was amazed that the DateField formfields did not come with embedded validators There are plenty of information on internet about setting specific dateformats for a specific DateField, but I wasn't able to find one kind of best practice that would work with all sort of localized date formats. Everything I found is very complicated for such a trivial issue, and I'm pretty sure there is a neat and easy to implement solution. Any suggestion? -

Best Explanation on the implementation of Dependency Injection in Python.?
I am a Software Engineer with significant amount of years of experience. I always desire using core development principles in my projects and these include using DI. which I have used alot in .NET projects and in Nodejs Projects. however I can't wrap my head around how DI actully works in python projects especially using FLask or Django.

Django Access Formset Instances from within Forms
I'm building a website where students can answer multiple questions on an assignment. I have models to store these objects. I'm trying to create a formset of questions for an assignment.
