Django model to relate with "container" of another model multiple objects
Sorry for weird topic naming but trying to find out the best way to create model relation with some kind of objects set. Lets say I have some models: class Furniture(models.Model): title = models.CharField() category = models.ForeignKey(Category) price = models.PositiveIntegerField() class Plumbing(models.Model): title = models.CharField() .... class Part(models.Model): title = models.CharField() code = models.CharField() I want to build relations of every Furniture / Plumbing instances with some set of Part instances (like fittings, screws, etc.). The first most obvious approach is to create ManyToMany field in Furniture and Plumbing models. But wondering if there is another approach to create some kind of "container" to have all the objects related together. As we know - there is no one-to-many field in Django and I don't want to keep planty null fields in Part if I decide to make relations for many other models (not only Furniture and Plumbing). I know that models archutecture is weid since it's a legacy code but any suggestions are welcome. -

CustomUser model setup in django rest framework
i tried creating a CustomUser model which inherits from AbstractBaseUser in drf, but when i try creating a new super user to log into the admin site, it doesn't work. it shows superuser created successfully but when running manage.py shell and trying to get that exact user i just created, it apparently doesn't exist. my custom user model: from django.db import models from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, Group, Permission from .managers import UserManager from django.utils.translation import gettext_lazy as lz import uuid import base64 ITEM = ( ("pastries", 'pastries'), ("rentals",'rentals'), ("music", 'music'), ("help", 'help') ) class CustomUser(AbstractBaseUser, PermissionsMixin): objects = UserManager() id = models.CharField(max_length=12, unique=True, primary_key=True, editable=False) username = models.CharField(max_length=55, unique=True) email = models.EmailField(verbose_name=lz('email address'), unique=True, max_length=255) first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) is_staff = models.BooleanField(default=False) is_active = models.BooleanField(default=True) is_superuser = models.BooleanField(default=False) last_login = models.DateTimeField(null=True, blank=True) is_verified = models.BooleanField(default=False) date_joined = models.DateTimeField(auto_now_add=True) groups = models.ManyToManyField( Group, related_name='accounts_user_groups', blank=True, help_text="the groups this user belongs to", verbose_name=lz('groups') ) user_permissions = models.ManyToManyField( Permission, related_name='accounts_user_permissions', blank=True, help_text="permissions for this user", verbose_name=lz('user permissions') ) USERNAME_FIELD = "email" REQUIRED_FIELDS = ["username"] def __str__(self) -> str: return self.email @property def get_full_name(self): return f'{self.first_name} {self.last_name}' def save(self, *args, **kwargs): if not self.id: # Generate a shorter base64-encoded UUID hex_string … -
pyodbc Transactions in Django View are Committing Changes Despite Rollback Attempts
I'm working on a Django application where I'm using pyodbc to connect to an AWS RDS SQL Server database. I need to run a series of raw SQL queries (including INSERT, UPDATE, DELETE, DISABLE or ENABLE a trigger etc.) as a transaction, ensuring that no changes are committed if any error occurs during execution. However, I’m running into an issue where changes are getting committed to the database even when an error occurs, and I call rollback(). Here’s what I’ve tried so far: Set autocommit = False on the pyodbc connection to prevent automatic commits. Used multiple cursors for different SQL statements, all under the same connection with autocommit = False. Wrapped the Django view with @transaction.non_atomic_requests to disable Django’s default transaction handling. Also tried wrapping the code with transaction.atomic() to see if Django’s transaction management could help. Despite all of these efforts, changes are still being committed to the database after the error occurs in the Django view, but when I run the exact same code in a standalone Python script (outside of Django), the rollback works perfectly, and no changes are committed. Here’s a simplified version of the code I’m using: import pyodbc from django.conf import settings from … -
Issue with django-crispy-forms and django-filter: CSS class not applying to custom ChoiceFilter field
I'm using django-filter and django-crispy-forms to create a filter form in Django, but I'm having trouble applying a CSS class to a custom ChoiceFilter field. The CSS class is successfully applied to the date field but does not work for the transaction_type field, which is defined as a ChoiceFilter. Here’s my current code: import django_filters from crispy_forms.helper import FormHelper from crispy_forms.layout import Layout, Field from .models import Transaction class TransactionFilter(django_filters.FilterSet): type = django_filters.ChoiceFilter( choices=Transaction.TRANSACTION_TYPE_CHOICES, field_name="type", lookup_expr="iexact", empty_label="Any", ) class Meta: model = Transaction fields = ['transaction_type', 'date'] def __init__(self, *args, **kwargs): super(TransactionFilter, self).__init__(*args, **kwargs) self.form.helper = FormHelper() self.form.helper.form_method = 'GET' self.form.helper.layout = Layout( Field('transaction_type', css_class='MY-CLASS'), Field('date', css_class='MY-CLASS'), ) In this setup, I expected both fields to have the MY-CLASS CSS class, but only the date field reflects it, not transaction_type. I suspect this might be due to transaction_type being a custom ChoiceFilter field, but I'm not sure how to resolve it. I've tried a few different approaches, such as updating widget attributes and applying CSS directly through attrs, but nothing has worked so far. Has anyone encountered this issue before or have suggestions on how to force the CSS class to apply to the ChoiceFilter field? -

How to ManifestStaticFilesStorage with django-storages, boto3 on DigitalOcean Spaces Object Storage?
Context: I am running Django==5.1.2. I need to have cache busting for my static files on prod. On dev, my settings are like so STORAGES = { "default": { "BACKEND": "django.core.files.storage.FileSystemStorage", }, "staticfiles": { "BACKEND": "django.contrib.staticfiles.storage.ManifestStaticFilesStorage", }, } STATIC_URL = "static/" STATIC_ROOT = os.path.join(BASE_DIR, "staticfiles") This works as you would expect. When debug=False, django uses the hashed static files for the urls. But on prod my settings are like so # DigitalOcean Spaces Settings # Ref: https://www.digitalocean.com/community/tutorials/how-to-set-up-object-storage-with-django AWS_ACCESS_KEY_ID = os.getenv("DO_SOS_ACCESS_KEY_ID") AWS_SECRET_ACCESS_KEY = os.getenv("DO_SOS_SECRET_ACCESS_KEY") AWS_STORAGE_BUCKET_NAME = os.getenv("DO_SOS_STORAGE_BUCKET_NAME") AWS_S3_ENDPOINT_URL = os.getenv("DO_SOS_ENDPOINT_URL") AWS_S3_OBJECT_PARAMETERS = { "CacheControl": "max-age=86400", } AWS_DEFAULT_ACL = "public-read" STORAGES["default"]["BACKEND"] = "storages.backends.s3boto3.S3Boto3Storage" STORAGES["staticfiles"]["BACKEND"] = "storages.backends.s3boto3.S3Boto3Storage" AWS_S3_SIGNATURE_VERSION = ( "s3v4" ) AWS_S3_CUSTOM_DOMAIN = os.getenv("DO_SOS_CUSTOM_DOMAIN") # Static & Media URL STATIC_URL = f"{AWS_S3_ENDPOINT_URL}/static/" MEDIA_URL = f"{AWS_S3_ENDPOINT_URL}/media/" As you can see, the backend is using "storages.backends.s3boto3.S3Boto3Storage" on prod instead of "django.contrib.staticfiles.storage.ManifestStaticFilesStorage". Which is kindof my problem. Whatever static content is saved to my Digital Ocean Spaces Object Storage is not hashed. How can I configure my django project to save the hashed static files to my Spaces Object Storage? -
Document is empty after performing fitz.open() on an io.BytesIO stream of a pdf
I am trying to get a PDF file from Mongodb and convert it to an io.BytesIO stream to keep it in the memory. Here is the snippet. fs = gridfs.GridFS(db) outputData = fs.get(file_id).read() pdf_stream = io.BytesIO(outputData) # Open the PDF from the stream doc = fitz.open(stream=pdf_stream, filetype="pdf") Running the Debugger I can see that the outputData is correct and has b'%PDF-' indicating a valid PDF. The pdf_stream is also generated correctly, but when I try to open this using fitz.open(), the document created is empty and returns Document('', <memory, doc# 2>) I am not able to figure out what the problem is and would like to have to help. -
Follow-up: How to override the Map Widget in Django Admin in which Geom Data Loaded via LayerMapping?
This question follows up on my initial query about dynamically changing the color of shapefile layers on a Django Admin Leaflet map. In my GeoDjango project, I'm loading geometry data via the LayerMapping method. Below is the load.py file I'm using for this: from django.contrib.gis.utils import LayerMapping from .models import Municipality municipality_mapping = { 'reg_code': 'Reg_Code', 'reg_name': 'Reg_Name', 'pro_name': 'Pro_Name', 'mun_code': 'Mun_Code', 'mun_name': 'Mun_Name', 'mean_ctrl': 'mean_ctrl', 'geom': 'MULTIPOLYGON', } zonalmeanctrl_shp = "path/to/shapefile.shp" def run(verbose=True): lm = LayerMapping(Municipality, zonalmeanctrl_shp, municipality_mapping, transform=False) lm.save(strict=True, verbose=verbose) In admin.py, I configured the admin panel with LeafletGeoAdmin: from django.contrib import admin from .models import Municipality from leaflet.admin import LeafletGeoAdmin class MunicipalityAdmin(LeafletGeoAdmin): list_display = ('pro_name', 'reg_code', 'reg_name', 'mun_code', 'mun_name', 'mean_ctrl') admin.site.register(Municipality, MunicipalityAdmin) Now, I would like to go further by customizing the map widget to dynamically style the geometries based on certain attributes (e.g., changing the color based on the mean_ctrl value). How can I override the map widget in Django Admin to apply dynamic colors to these shapefiles loaded via LayerMapping? -
django rest framework with simplejwt getting a 200 ok response even for invalid tokens
I am using django-rest-framework, djoser and simplejwt to build out token auth for user accounts. I can create an account, activate and login with Postman. But for some reason I having an issue with the /refresh and /verify endpoints. I'm also having an issue with /logout and /auth/me but I'm guessing if I can fix the /refresh and /verify endpoints the other ones will also fix themselves.

Django/Whitenoise collectstatic causing Permission Denied Error
I have been struggling with this for weeks and have hit a brick wall. Im trying to deploy a Django App and Im using Whitenoise to handle Static Data.

How do I keep persistent web socket connections with another API in my Django app?
I'm developing a Django application that requires a persistent WebSocket connection to continuously fetch live data from a crypto market API. I need to keep this WebSocket connection active throughout the application's lifecycle to update my local data as new information arrives. This updated data will later be displayed on the front end, so I anticipate needing a separate WebSocket connection between the front end and back end (one connection for backend-to-crypto market API, and another for backend-to-frontend). I'm new to this type of setup and would appreciate guidance on the best practices for implementing it. I've explored Django Channels, Uvicorn, and Daphne. Although Django Channels might be suitable for the frontend-backend WebSocket connection, I'm more focused on maintaining a robust event-loop structure for the backend-to-crypto API connection to ensure it remains alive and responsive. I'm considering building a custom event-loop manager to handle this, but I'm unsure if it's the best approach. Could you suggest any established methods, libraries, or patterns for maintaining a continuous WebSocket connection for real-time data updates in a Django application? Thank you in advance! -
How to handle pre-selection of related fields and ensure proper update of many-to-many relationships in Django REST Framework?

Multi tenant structure where frontend is custom domain : Cookies set as thirdparty

having generic fields based on model objects in forms.py in django
We have a model called Permission and we have listed it in a form in django template like this: {% for item in permissions %} <tr> <td class="text-nowrap">{{ item.app }}</td> <td> <div class="d-flex"> <div class="form-check me-3 me-lg-5 mb-0 mt-0"> <input class="form-check-input" type="checkbox" name="{{ item.app }}_add" id="{{ item.app }}ManagementWrite"> <label class="form-check-label" for="{{ item.app }}ManagementWrite">add</label> </div> <div class="form-check me-3 me-lg-5 mb-0 mt-0"> <input class="form-check-input" type="checkbox" name="{{ item.app }}_read" id="{{ item.app }}ManagementRead"> <label class="form-check-label" for="{{ item.app }}ManagementRead">read</label> </div> <div class="form-check me-3 me-lg-5 mb-0 mt-0"> <input class="form-check-input" type="checkbox" name="{{ item.app }}_update" id="{{ item.app }}ManagementUpdate"> <label class="form-check-label" for="{{ item.app }}ManagementUpdate">update</label> </div> <div class="form-check mb-0 mt-0"> <input class="form-check-input" type="checkbox" name="{{ item.app }}_delete" id="{{ item.app }}ManagementDelete"> <label class="form-check-label" for="{{ item.app }}ManagementDelete">delete</label> </div> </div> </td> </tr> {% endfor %} So here We have four options for read , write , update and delete for each object in the Permission table . But How can i make a form in forms.py for this that i have BoleanFields for each access level? for example four field for ticket app (read , write , update , delete) and four field for users app as the same . -
How to pre-populate a form field with model's foreignkey field's value at form load in Django
