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
I'm working on a Django project where I have two models, Product and Color. These two models are connected via ManyToManyFields.

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 … -
django ORM query filter methods running multiple filter duplicates joins

But running filters on both fields give redundant JOINS and thus inaccurate results: The query … -

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? -
Django + Crispy form - Readonly field for specific usergroup/user without Javascript : possible?
I know how to set a field readonly using the helper, but I'd like to disable values changes for specific users. 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 … -
Django IntegerField doesn't work as primary_key when CharField does for unmanaged model using custom DbManager
Working with Django5.0 updating a legacy oracle database with multiple DBs/Schemas. class OtherDbManager(models.Manager): def get_queryset(self): odb = "default" if hasattr(self.model, 'my_db'): odb = self.model.my_db return super().get_queryset().using(odb) class AAAModel(models.Model): class Meta: managed = False abstract = True objects = OtherDbManager() class BBBModel(AAAModel): class Meta(AAAModel.Meta): managed = False abstract = True my_db = 'bbb_db' class WackyObj(BBBModel): class Meta(BBBModel.Meta): managed = False db_table = '"%s"."%s"' % ("BBB_DB", "WACKY_OBJ") #myinteger = models.IntegerField(primary_key=True, null=False) #queryset operations fail if this is an integer field myinteger = models.CharField(primary_key=True, null=False) available_on = models.DateField() The underlying Oracle table "WACKY_OBJ" has filed MYINTEGER as NUMBER, NOT NULL. now if I do something like: target = WackyObj.objects.get(myinteger=8675309) I'll get my object back, but if I use an IntegerField instead (commented out in WackyObj class definition above): target = WackyObj.objects.get(myinteger=8675309) I'll get: wackymod.models.WackyObj.DoesNotExist: WackyObj matching query does not exist. Is this a bug? Also, in case it's relevant, i'm using a DatabaseRouter like so: from wackymod.models import AAAModel class XXXRouter: def db_for_read(self, model, **hints): if issubclass(model, AAAModel): return model.my_db return None def db_for_write(self, model, **hints): if issubclass(model, AAAModel): return model.my_db return None def allow_relation(self, obj1, obj2, **hints): return None def allow_migrate(self, db, app_label, model_name=None, **hints): return False As shown above, I've tried … -

Django - access data in a model from a model with a foreign key
I have reduced code to display two models for simplicity. I am very new to Django and have been following the tutorial for the 2nd time but creating my own models. class Products(models.Model): product_name = models.CharField(max_length=50,unique=True,null=False) def __str__(self): return self.product_name class Current_tests(models.Model): product = models.ForeignKey(Products, on_delete=models.CASCADE) no_samples = models.IntegerField(default=0) stagecode=models.CharField(max_length=30,default="UPDATE REQUIRED") def __str__(self): return self.stagecode Where I have got a bit stuck is on how I access the data in my Products model using the foreign key in Current tests. For example I might want the product_name associated with a specific Current_test data row id or look product_name based on a stage code value. Equally, how do I get all stagecode for a given product_name. On the tutorial its done like this: q = Question.objects.get(pk=1) # Display any choices from the related object set -- none so far. >>> q.choice_set.all() <QuerySet []> https://docs.djangoproject.com/en/5.1/intro/tutorial02/ When I swap my classes in I get "AttributeError: 'Current_tests' object has no attribute 'product_name_set'. I have looked at many questions on here that suggest using "related name", "filter" but I have not been able to access data. Thanks -
Angular+Django how to access cookie under different domain
This is a follow up to my previous question (Angular+Django CSRF token not being saved as cookie) since I understand the underlying problem now. I have a Angular and Django setup and I am trying to get it to work with CSRF tokens. The way I have it set up is, Django includes a token in the response and it's saved as a cookie. Then my Angular interceptor gets the token from the cookie storage and includes it in the header of every subsequent request. This seems to be the only way that works and it works fine locally. The problem when I deploy the backend is that the returned cookie has a different domain (used to be localhost, now it's the name of the backend host). This means that the Angular cookie service isn't able to find it, so the requests have no CSRF token. I tried using HttpXsrfTokenExtractor instead, as proposed in https://www.stackhawk.com/blog/angular-csrf-protection-guide-examples-and-how-to-enable-it/. But that doesn't find the cookie either. I tried using the built-in Angular support for CSRF tokens (https://angular.dev/best-practices/security#httpclient-xsrf-csrf-security) but it doesn't include a token in any request regardless of the setup. Someone recommended reading the cookie manually from the backend response and then setting it … -
Starting a Django Web App as a Service using nginx and uWSGI fails

Celery task completion check isn't checking the correct task

1 min delay in Vue.js rendering
So i have an application which has django as backend and vue.js on the frontend. This app intereacts with a source with websocket connection and this source continuosuly sends values to the application. whenever these values exceed any nominal state, those exceeded values are added in the symtomslist and the main page displays the updated values instantly, as the watch function of the page is set to watch on symptomslist. So the problem i have is, when we logged in and started the simulation, the app has been rendering the new values instantly when the values were changed, but after somrtime, even if the values were changed, the page has been rendering them after 1 min(even though different people logged in at different times, the lag in rendering started to all of us at the same time). we timed it multiple times and it measured 1 min each time. but when we logout and log back in, the state is again being rendered instantly. can you tell what might be causing this issue The console is logged every second. Maybe this is the issue? -
Pagination within Django - combining two projects
I am working off of two different projects. I have the Example By 5 and a YT series that I previously used to get started with Django. I liked the Pagination from the yt series so I decided to use that method, however in the Example By process, we moved from the Class base view to a function and now the pagination does not show up. I have added what I thought was needed in the view and html page but still getting nothing.

Best Approach for Text Chunking in AI Chat Agent using React and Django (Langchain) without Sockets?
I’m currently building an AI chat agent that needs to handle text chunking and display responses word by word in real-time. My setup involves a React (frontend) and Django Langchain (backend) integration. I want to achieve this without relying on sockets to stream data and instead use an approach that can fetch and display responses as they are generated, ensuring the user sees a continuous flow of words. Here's a breakdown of my current setup: Frontend: React (with or without Redux) Backend: Django integrated with Langchain for handling the AI logic What I’m Looking For: Text chunking: Best practices for chunking AI responses (word by word or partial sentences) and updating the UI in React. Real-time updates: How to fetch and display this data incrementally (e.g., fetching a stream or chunks) without using sockets. Efficient handling: Strategies for making the experience smooth for users, especially on the frontend with React. I prefer not to use WebSockets and want to stick with traditional HTTP requests if possible. Looking for an approach that handles data/response chunking seamlessly so users get real-time updates without long waits. If anyone has experience with Langchain in this context or can share ideas on how to achieve … -

The list of urlpatterns should not have a prefix string
In Django 5.0 I get the error: The list of urlpatterns should not have a prefix string. My code is: from django.conf.urls import url from django.urls import path, include from django.contrib import admin app_name = 'AppServer_test' # specified as string literal rather than a variable urlpatterns = [ path('admin/', admin.site.urls), path('api/v1.0/user/', include('user_accounts.urls')), path('api/v1.0/notifications/', include('notifications.urls')), path('api/v1.0/feedback/', include('feedback.urls')), # path('', include('AppServer_test.urls')), # check that AppServer_test.urls is a valid and accessible module ] I've got the same code working in Django 3.2, the error only occurs in a system using 5.0 I've tried using round brackets instead of square as in this post: Django 1.11 url pattern error, how to solve? -

Django Summernote plugin upload image by userid
I am using the Summernote plugin for Django and my target is to allow users to upload media inside the server. At the moment files are organized (by default) in a folder named with the upload date. Something like: "ProjectName/media/django-summernote/2024-10-11/989d2f98-ad3c-47d6-9c07-e5f6d0c731e6.png" "ProjectName/media/django-summernote/2024-10-17/13d646b8-d7cd-4e04-a76a-804a1ee0d090.jpg". Is it possible to change the path and include the user_id in the path? Something like "ProjectName/media/django-summernote/User100/989d2f98-ad3c-47d6-9c07-e5f6d0c731e6.png" "ProjectName/media/django-summernote/User200/13d646b8-d7cd-4e04-a76a-804a1ee0d090.jpg".
