Got attribute error when trying creating model
I got this error message Got AttributeError when attempting to get a value for field id on serializer IngredientSerializer. The serializer field might be named incorrectly and not match any attribute or key on the Ingredient instance.

Send an http request from django server inside docker container to another server that is located on localhost not inside docker
I have a django project inside docker container. I have several containers for backend, frontend, redis, celery and db thar are served by docker compose. I need to send an http request made by python lib requests to a server that is outside of docker but is started on the same computer (on localhost). This code worked perfectly when django server wasn't inside docker container. There is 500 status code from this function at the moment. How can i do this?

Django Tastypie API Slow Response Time with Annotate Count and Pagination
I'm working with a Django Tastypie API that processes a large QuerySet. I need to perform an annotate with a Count on a related table, which is also very large. Afterward, I return the response using paginator to handle the pagination. However, the API is taking a significant amount of time to return the results. Here is a simplified version of the annotate that seems to be causing the most delay: .annotate( dynm_calc=Count('devices', filter=Q(devices__groups__id__in=ids_list), distinct=True) ) My main concerns are: QuerySet Evaluation: Is the entire QuerySet being evaluated despite using pagination? If so, could this be the reason for the slow response times? Performance Optimization: How can I optimize this query or improve the performance of the API response? Splitting the QuerySet: Would splitting the QuerySet into smaller parts before applying the annotate be beneficial? If yes, how can this be effectively implemented? Any insights or suggestions on how to tackle this issue would be greatly appreciated. Thank you! -
How to recover Django users password after migrating project to a different server
I migrated my Django project to a different server, so I figured that the database is the most important thing on the server since my code is on GitHub and my media files on S3 bucket. So I made a backup of the database as an SQL dump. I setup my project, restored the database, configure my domain etc. and everything seems like nothing changed (works well). Then I tried to login but it says incorrect password. I'm thinking the way Django hash the password has changed which makes it not match the hash on the database. Every data on the database is up to date. How can I recover the password of the users and what are best practice methods to midrate successfully? I don't have access to the old server anymore. -

Django custom lookup, rhs receives %s only
I want to create a custom icontainsall lookup such that when a user searches for a phrase with a space in it, I want to convert it into a like on all words with AND (so that order of word does not matter). i.e. If user searches for 'egg milk', the predicate becomes name LIKE %egg% AND name LIKE %milk%. This is how my lookup looks: from django.db.models import CharField, Lookup, TextField class CaseInsensitiveContainsAllLookup(Lookup): lookup_name = 'icontainsall' def as_sql(self, compiler, connection): lhs, lhs_params = self.process_lhs(compiler, connection) rhs, rhs_params = self.process_rhs(compiler, connection) print(rhs) # shows %s and not 'egg milk' predicate, params = [], [] # escape \ and % rhs_list = rhs.replace('\\', '\\\\').replace('%', '\\%').split(' ') for rhs in rhs_list: params += lhs_params + rhs_params predicate.append(f"LOWER({lhs}) LIKE LOWER({rhs})") return ' AND '.join(predicate), params CharField.register_lookup(CaseInsensitiveContainsAllLookup) TextField.register_lookup(CaseInsensitiveContainsAllLookup) However, rhs receives only %s and not egg milk. How can I go about achieving what I want using a lookup? -
How do I check if a user is not in any group in Django?

'uv' is not recognized as an internal or external command in Windows when trying to create a virtual environment
I'm trying to create a virtual environment in Windows using the uv command, but I keep encountering the following error: 'uv' is not recognized as an internal or external command, operable program or batch file. 1] Installation: I installed uv using pip install uv within my Python environment. I verified the installation by running pip list, and uv appears in the list of installed packages. 2] Path Configuration: I checked my PATH environment variable and confirmed that the Python Scripts directory (where uv.exe should reside) is included. I tried using the full path to the uv executable, but the error persists. 3] Environment Setup: I ensured that my virtual environment was properly created and activated using: python -m venv myenv myenv\Scripts\activate 4] Other Commands: Other Python-related commands like pip, python, etc., work fine without issues. I also tried uninstalling and reinstalling uv but still face the same problem. Why is the uv command not being recognized despite being installed and listed by pip? How can I resolve this issue and successfully create a virtual environment using uv? -
Runtime.ImportModuleError: Unable to import module 'vc__handler__python' if the root folder is set one level above the server folder on vercel
I recently watched video “Deploy Django Project on Vercel with Supabase PostgreSQL: Step by Step Guide”. I followed this video step by step, and my project was really deployed. But it deployed if i picked my folder python_server/ as root directory. But I need to select the folder one level up as root directory. I have project structure like this: Project/ ├── python_server/ │ ├── __init__.py │ ├── mysite/ │ │ ├── __init__.py │ │ ├── settings.py │ │ ├── urls.py │ │ ├── wsgi.py │ ├── manage.py │ ├── gif_service/ │ │ ├── templates │ │ ├── views.py │ │ ├── urls.py │ ├── static │ ├── staticfiles ├── public ├── views ├── js_server I copied my static files from /public and views from /views to /python_server. And I picked /python_server as folder root. It’s works well for vercel. But it’s not good for me. Because I use views from /views and static files from /public for both server: Express server and Django. And so It’s not good practice to have copy of that static and html files. So I need to deploy vercel not with python_server/ as root folder, but with Project/ as root folder. I really tried … -
Not able to select database for database queries in django
I'm trying to direct my read queries to my read replica in a production setup. Django allows defining multiple databases, so I added two databases like: DATABASES = { "default": { "NAME": "ironbank", "ENGINE": "django_postgrespool2", "USER": "postgres", "PASSWORD": os.getenv("DATABASE_PASSWORD", "postgres"), "HOST": os.getenv("DATABASE_HOST", "localhost"), "PORT": os.getenv("DATABASE_PORT", "5432"), "CONN_MAX_AGE": 0, }, "replica": { "NAME": "ironbank_replica", "ENGINE": "django_postgrespool2", "USER": "postgres", "PASSWORD": os.getenv("DATABASE_PASSWORD", "postgres"), "HOST": os.getenv("REPLICA_DATABASE_HOST", "localhost"), "PORT": os.getenv("REPLICA_DATABASE_PORT", "5432"), "TEST": { "MIRROR": "default", }, "CONN_MAX_AGE": 0, }, } Here I'm using two different databases to test it setup locally.

A logger can have multiple handler 'loggers': { # notice the blank '', Usually you would put built in loggers like django or root here based on your needs '': { 'handlers': ['console'], 'level': 'DEBUG', 'propagate': True, }, }, } -
is it possible to use django-push-notifications for both android/ios without apns? (if I have both apps in firebase)
I want to use django-push-notifications library for push notifications. My mobile app part configured firebase for both android and ios. In library's documentations they separated logic and configuration of gcm and apns devices. Can I use just GCMDevice for both android and ios devices (to save them, send message) as it is already configured in firebase? Or should I configure apns in django also as it is mentioned in documentation from firebase_admin import auth # Initialize the default app (either use `GOOGLE_APPLICATION_CREDENTIALS` environment variable, or pass a firebase_admin.credentials.Certificate instance) default_app = firebase_admin.initialize_app() PUSH_NOTIFICATIONS_SETTINGS = { "APNS_CERTIFICATE": "/path/to/your/certificate.pem", "APNS_TOPIC": "com.example.push_test", "WNS_PACKAGE_SECURITY_ID": "[your package security id, e.g: 'ms-app://e-3-4-6234...']", "WNS_SECRET_KEY": "[your app secret key, e.g.: 'KDiejnLKDUWodsjmewuSZkk']", "WP_PRIVATE_KEY": "/path/to/your/private.pem", "WP_CLAIMS": {'sub': "mailto:development@example.com"} } -
Static not loaded when django project deployed
I'm trying to deply my django site, and I did to my ip address, but when I load page online it doesn't load static files. I tried changing different settings on a server and on django files, but I'm out of ideas. I would appreciate a pair of fresh eyes. for sites-available I did this: sudo nano /etc/nginx/sites-available/django-site Output: server { listen 80; server_name xx.xx.xxx.xx; #my ip address location = /favicon.ico { access_log off; log_not_found off; } location /static/ { alias /home/muser/django-site/staticfiles/; } location / { include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } } this is settings.py STATIC_URL = 'static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static'), ] #media MEDIA_URL = 'media/' MEDIA_ROOT = BASE_DIR / 'media' It might be that this is all correct, but it might be that urls aren't set up properly. So please see urls.py urlpatterns = i18n_patterns( path(_('admin/'), admin.site.urls), path('rosetta/', include('rosetta.urls')), path('', include('my_app.urls', namespace='my_app')), ) if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT) urlpatterns += static(settings.STATIC_URL,document_root=settings.STATIC_ROOT) Any ideas what I did wrong? Thanks in advance!
