Django project hosting with Vercel
I am trying to host my Django project on Vercel, but it shows some errors related to the 'requirements.txt' file in my project, something related to dependencies. This is the error message: Error: Command failed: pip3.12 install --disable-pip-version-check --target . --upgrade -r /vercel/path0/requirements.txt ERROR: Cannot install -r /vercel/path0/requirements.txt (line 19) and idna==3.3 because these package versions have conflicting dependencies.

In Django, combining and ordering counts across two model fields
I have these two simplified models, representing people and letters that have been sent and received by those people: class Person(models.Model): name = models.CharField(max_length=200, blank=False) class Letter(models.Model): sender = models.ForeignKey(Person, blank=False) recipient = models.ForeignKey(Person, blank=False) I want to display a list of Persons ordered by how many times they've sent or received any letters. I started doing this very laboriously, but figure there must be a simpler way. e.g., this gets the Person IDs and counts of how many times they've sent a Letter: senders = ( Letter.objects.order_by() .values(person_id=F("sender")) .annotate(count=Count("pk")) .distinct() ) I can do the same for recipients. Then combine the two into a single list/dict, adding the counts together. Sort that. Then inflate that data with the actual Person objects, and pass that to the template. But I feel there must be a less laborious way, starting, I think, with a single query to get the combined sent + received counts. -

why my django app not including content-type on request headers?
I have simple Django app with some request send via ajax and django will return different responses depends on content-type I declare on ajax request. This code work fine on my local computer, however in my hosting server I always get 500 server error , it return keyerror: content-type. After checking headers list I notice that content-type not exist in the headers list on hosting, but in my local computer it exists. Django lines: if request.headers['content-type'] == 'application/json': response = render_to_string(self.templates, {'form': form}, request) data = {'success': True, 'rendered': response, 'title': self.title} return JsonResponse(data) else: return render(request, 'base.html', {'form': form, 'title': self.title, 'template': self.templates}) AJAX Lines: $.ajax({ url: link, contentType: 'application/json', dataType: 'json', success: function(data){ $('title').html(data.title); $('#content').html(data.rendered); window.history.pushState({'data': data, 'path': link}, "", link) $('#nav-menu').attr('data-path', link); I confuse what the cause, I already collected staticfiles. -
Deployed Django app returning 301s and NS_ERROR_REDIRECT_LOOP
I've just setup my Django app in my VPS using gunicorn and nginx, and I cannot access it in my browser through the custom domain that I assigned it to (ipantun.com) because it keeps returning 301s and finally stopped with NS_ERROR_REDIRECT_LOOP. I followed this tutorial, and everything works fine with running it locally and also using gunicorn. So I suspect it may have something to do with how I configure my nginx and maybe even Cloudflare which is my domain registrar. A thing that I noticed is if I go to the URL ipantun.com, then it will redirect to www.ipantun.com and it will also query the full URL as its URI as in the final URL will be https://www.ipantun.com/www.ipantun.com. I expected the redirect of non-www to www as I have setup a Redirect Rule on Cloudflare to do so, but the querying is something I've never encountered before so I'm lost. Every log files of gunicorn and nginx showed nothing wrong. Everything in /etc/nginx/sites-available is also in /etc/nginx/sites-enabled. Not sure if it's relevant, but I'm also serving another React app from the same server on the same port ie. port 80. But as you'll see in the nginx config files … -

Choreo: Connecting Repo without Creating a Component?
Choreo newbie here... I am going through Tech With Tim's YouTube tutorial named "Django & React Web App Tutorial - Authentication, Databases, Deployment & More..." and I ran into a difference between his video (made March 2024) and how Choreo works now (19 Oct 2024). In Tim's video, he made a new project, linked it with a GitHub repo but without creating an initial component (see screenshot below). Is there a way to still do that? Image from video from Tech With Tim I started by creating a project by entering a name and clicking "Create". New Project dialog Then clicked "Start" in the "Create Multiple Components" section to connect a Git repository. Connect Repo But there is no way to then create the project with the connected repo without creating a component. Must create a component Is the way Tim did it in his video not available anymore? Did I make a mistake somewhere that took me in a different path? -

gRPC - postgres connection issue in django: connection already closed
I am using django-grpc-framework in my django rest project. I setup a grpc service to get some user information from this project using grpc server. This grpc service is running using kubernetes, and after a while of running, I get the following error: django.db.utils.InterfaceError: connection already closed I restart the deployment and the issue goes away. I recently added the following line after every grpc service method: django.db.close_old_connections() but now I see that some rpc calls take 20 ms to connect to the database, and this is slowing the response time. Is there any other way to fix my problem without causing long response times. -

Force host part in BASE url when using Vite's development server
I have a somewhat non-conventional setup where I use a Vite/Vue SSR server for template rendering behind a Django server. I.e. Django calls node, gets html back, and sends it back to the browser. I encountered a problem with Vite's dev server in that it doesn't respect a full BASE url like https://bar.com/foo/ (it strips out the origin part, which is documented behavior). Without the origin part, however, the generated html and other assets contain urls that the browser treats as relative to the origin of the Django server, which obviously doesn't work. Is there a way to force Vite to include the origin in the BASE url, or is my only option to proxy back to the Vite server from Django? -

Restricting color options in Django admin form based on previously selected colors
I have two models, Product and Color, connected via ManyToManyFields. I want to restrict the color options available when editing a product in the Django admin interface. Models: class Color(models.Model): coid = ShortUUIDField(length=10, max_length=100, prefix="col", alphabet="abcdefgh") name = models.CharField(max_length=20) code = ColorField(default='#FF0000') product_varients = models.ManyToManyField('Product', related_name='color_variants', blank=True) image = models.ImageField(upload_to=color_directory_path, default="product.jpg") class Product(models.Model): pid = ShortUUIDField(length=10, max_length=100, prefix="prd", alphabet="abcdef") title = models.CharField(max_length=100, default="Apple") color = models.ManyToManyField(Color, blank=True) price = models.DecimalField(max_digits=10, decimal_places=2, default=1.99) Goal: When creating or editing a product, I want to restrict the colors in the color field to those that have been previously selected in the color field of the same product. In other words, I want the color field to show only colors associated with the product’s color, not all colors available in the database. What I Need: I want the color field in the Product admin form to display only the colors that are linked to the color of that product. If no color is set, I want the color field to be empty or show no options. Current Behavior: When I click on the color field in the Product admin form, it redirects me to the Color model, and then if I click on the … -

Django Admin: Limit ManyToManyField options based on previously selected ManyToManyField

Why model instance is not being supplied to `ModelForm` inside a `DeleteView`
With Django 5.0.2, let's start with a simple model: from django.db import models class Book(models.Model): title = models.CharField(max_length=100) I want to do some form validation within ModelForm to determine whether or not the deletion should happen inside DeleteView. Simply put, I think the form is already capable of showing non-field errors and I want to avoid using messages.error() to sending back an error message. So I started with ModelForm: from django.forms import ModelForm class DeleteBookForm(ModelForm): class Meta: model = Book fields = [] def clean(self): super().clean() if not self.deletable(): self.add_error(None, 'This object can not be deleted') def deletable(self) -> bool: # do some evaluation on Book here book = self.instance if book.title == 'delete me please': return True else: return False and then the DeleteView: from django.views.generic import DeleteView from django.http import HttpResponseRedirect class DeleteBookView(DeleteView): model = Book form_class = DeleteBookForm def form_valid(self, form): self.object.delete() messages.success(self.request, 'The object has been deleted successfully.') return HttpResponseRedirect(self.get_success_url()) But self.instance appears to be None inside DeleteBookForm.deletable(). Indicating that the Book model instance is not being supplied/inserted to the ModelForm when it is being created. I believe this is not the case with UpdateView. Spent some time reading, I found this code on BaseDeleteView.post() (DeleteView's … -

Issues with Running Django Management Command as an Always On Task on PythonAnywhere
I built and deployed my Django website on PythonAnywhere. I have a script in my app/management/commands/my_command.py that I intend to keep always running. I tried using the PythonAnywhere Always On Task feature for this, but the status never changes from "starting" to "running". There is no problem with the script itself because when I run: bash (venv) $ source /home/myusername/.virtualenvs/myenv/bin/activate && cd /home/myusername/myproject && python manage.py my_command the script runs successfully, and then when I go to my Always On Task console, I see that it ran successfully and was recorded in that console. But the problem is that I don't want to always manually run it in my Bash console. I have followed the instructions on the PythonAnywhere help page, and I have changed my task command to all the options I can use. I tried: bash source virtualenvwrapper.sh && workon myenv && python /home/myusername/myproject/manage.py my_command But it never changes to "running." I also tried: bash /home/myusername/.virtualenvs/myenv/bin/python /home/myusername/myproject/manage.py my_command Again, it never changes to "running." However, if I run the script in the Bash console, the Always On task prints out my success message! What am I doing wrong? -

The only way I found consists in adding a condition in the the form taking in account the user.is_staf or user.is_superuser. Form call in views.py s_form = stock_inline_formset( instance=product, form_kwargs={'empty_sst': empty_sst, 'user_is_staff': user.is_staff}) Condition in forms.py class SstStockForm(forms.ModelForm): class Meta: model = SstStock fields = ('qty', 'warehouse', 'maxsst', 'adresse', 'pua', 'cau') def __init__(self, *args, **kwargs): self.empty_sst = kwargs.pop('empty_sst', None) self.user_is_staff = kwargs.pop('user_is_staff', None) super().__init__(*args, **kwargs) if not self.user_is_staff: self.fields['qty'].widget.attrs = {'readonly': 'readonly'} self.fields['pua'].widget.attrs = {'readonly': 'readonly'} self.fields['cau'].widget.attrs = {'readonly': 'readonly'} [...] Is it the better way ? Otherwise I could do it with JS using the same condition based on the user for setting the input field readonly. I didn't find any ressource talking about this. -
Filtering Related Colors in Django Admin Based on Product Selection
Problem Statement: I am working on a Django project where I have two models: Product and Color. The Product model has a many-to-many relationship with the Color model through a field called product_varients. My goal is to filter the available colors in the Django admin interface based on the selected product. Specifically, I want to ensure that when creating or editing a Color, the product_varients field only shows colors that are not already associated with that product Models: Here are the relevant parts of my models: from django.db import models from shortuuid.django.fields import ShortUUIDField class Color(models.Model): coid = ShortUUIDField(length=10, max_length=100, prefix="col", alphabet="abcdefgh") name = models.CharField(max_length=20) product_varients = models.ManyToManyField('Product', related_name='color_variants', blank=True) def __str__(self): return self.name class Product(models.Model): pid = ShortUUIDField(length=10, max_length=100, prefix="prd", alphabet="abcdef") title = models.CharField(max_length=100, default="Apple") color = models.ManyToManyField(Color, blank=True) def __str__(self): return self.title Current Implementation: In my admin.py, I have implemented a custom form for the Color model to filter the product_varients field. Here’s the relevant code: class ColorAdminForm(forms.ModelForm): class Meta: model = Color fields = '__all__' def __init__(self, *args, **kwargs): super(ColorAdminForm, self).__init__(*args, **kwargs) if self.instance.pk: # Editing an existing color self.fields['product_varients'].queryset = Product.objects.exclude( color=self.instance # Exclude products that already have this color ) else: # Creating a new …
