django model save operation not creating on default database
I have two databases defined: 'default': { 'ENGINE': 'django.db.backends.postgresql', 'USER': 'app-api-master', 'PASSWORD': 'sdf', 'HOST': 'localhost', 'NAME': 'ev_offshore_bkup' }, 'onshore_db': { 'ENGINE': 'django.db.backends.postgresql', 'USER': 'app-api-master', 'PASSWORD': 'sdf', 'HOST': 'localhost', 'NAME': 'ev_onshore_bkup' } In the model: def save(self, *args, **kwargs): kwargs['using'] = 'default' super().save(*args, **kwargs) NoTice I've commented these #kwargs['using'] = 'onshore_db' #super().save(*args, **kwargs) In the viewset: with transaction.atomic(): self.serializer_class = self.create_serializer_class created_user = viewsets.ModelViewSet.create(self, request, *args, **kwargs) created_user_id = created_user.data['id'] The create() only saves the record in onshore_db immediately and doesn't consider the default db. Even after commenting the onshore_db configuration, when I run the app, I find that the new model objects are created in onshore_db only and no records in default db. What could be the reason? There's also a db-router defined: def get_db_name(): cache_data = {} db = 'default' request = get_current_request() try: user_id = request.session._session_cache['_auth_user_id'] cache_data = cache.get(user_id, {}) except Exception as e: return db if cache_data.get('CLIENT_DB_NAME', None): db = cache_data.get('CLIENT_DB_NAME') return db class MatrixDBRouter: # TODO encrypt db name where data from onshore def db_for_read(self, model, **hints): return get_db_name() def db_for_write(self, model, **hints): return get_db_name() def allow_relation(self, obj1, obj2, **hints): return True def allow_migrate(self, db, app_label, model_name=None, **hints): return True But this only returns the default … -

The same uuid is generated for different objects in Django
When I run server on localhost I am able to add new objects in my postgre database through Django admin panel, but only one for every table. When I try to add second new object, it assigns the same uuid that has already been used. There is an example of model with uuid as primary key: models.py from django.db import models from authuser.models import User from django.utils import timezone import uuid class Thread(models.Model): idthread = models.UUIDField(default=uuid.uuid4(), primary_key=True, unique=True) date_created = models.DateTimeField(default=timezone.now) userid = models.ForeignKey(User, on_delete=models.DO_NOTHING) name = models.CharField() def __str__(self): return self.name Only after restarting the server it will assign new unique uuid to object that I would like to add. -
How to implement dual authentication (email and phone number) in Django Rest Framework?
I'm building a Django Rest Framework (DRF) application and I need to implement dual authentication, allowing users to sign in using either their email or mobile number. What is the best approach to implement this? I've already set up the authentication system using email, but now I need to extend it to support mobile number authentication as well. Should I create a custom authentication backend, or is there a DRF package that can help me achieve this more easily? I'd appreciate any advice or examples on how to implement dual authentication in DRF. Thank you! -
ModuleNotFoundError: No module named 'psycopg2' while makemigrations on postgres DB
I cloned a github project on Django and i was following the instructions to execute the program. I am new so, i went ahead and downloaded postgres and installed it. at the make migrations step, this error was logged along with bunch of paths :- ModuleNotFoundError: No module named 'psycopg2' i was following the steps given in the documentation file for this which are as follows : " Installing the Postgres and enabling it in the background We will go to telusko\settings.py in the project folder Around line 78, there's DATABASES dictionary, we will set the value for keys ('NAME', 'USER' & 'PASSWORD') to 'postgres' Then we'll execute python3 manage.py makemigrations & python3 manage.py migrate Finally, we will run the project by python3 manage.py runserver " i followed the steps, at the 3rd step, instead of 'postgre' as the password, i typed in the password asked at the installation process BUT at the 4th step when i run the python3 manage.py makemigrations this error is shown: ModuleNotFoundError: No module named 'psycopg2' i want this project somehow working till tomorrow so please help -
How to Submit Separate Actions from a Single Form Tag? (Django)
I have written the following code where a submit action with the value {{category.name}} unexpectedly triggers the "create" button in form_category, resulting in a "Please enter a name" message. This approach worked fine in a previous project using the same logic. I've confirmed that the urls.py is properly set up. What could be the issue? <form method="POST"> {% csrf_token %} category name: {{ form_category }} <input type="submit" value="create" formaction="{% url 'mk_category' %}"> <span> | </span> {% for category in categories %} <input type="submit" value="{{category.name}}" formaction="{% url 'index_with_category' category.id %}"> {% endfor %} </form> Thank you very much for your help! Wrapping each submit button in separate form tags resolves the issue. However, I plan to continue using multiple submit buttons within a single form in the future. I have checked urls.py multiple times and found no issues. Please help me with this. -

Embedded react component disable select text on other html elements
I am trying to include a react component in a django template which contains non-react content. My template contains the following code: {% load static %} <!DOCTYPE html> <html> <body> <h1>This text CAN NOT be selected</h1> <h2>React app</h2> <div id="react1"></div> <!-- this is the component that the react component will live in. --> <script src="{% static js %}" defer></script> <!-- js is a variable pointing to the main.XXXXX.js file. --> </body> </html> The variable js refers to the build/static/js/main.XXXXX.js-file build using npm run build and served using django. The index.js file (in react) simply add a component to the div: import React from 'react'; import { createRoot } from 'react-dom/client'; import App2 from './App2'; if(document.getElementById("react1") != null){ const root = createRoot(document.getElementById('react1')); root.render( <App2 /> ); } The component (App2.js) is a very simple hello-world example. The page renders correctly (the app is a simple counter app) as shown in the screenshot so all files are up-to-date. As can be seen I can select/interact with the application, but I cannot select the text defined in the tag (and more importantly, events such as button clicks outside of react are not triggered etc.). The React counter-app works as expected. I have googled … -
Cannot index models from Django to Elasticsearch
I have a Django project where we're going to use Elasticsearch for a full-text search. I have a task to connect it with the existing Django project. The first thing I found django-elasticsearch-dsl package. I did everything like in tutorial and all worked fine, but the idea was in using elasticsearch-dsl. I don't understand how to create indexes right now. If in django-elasticsearch-dsl the only thing I need is to run python3 manage.py search_index --rebuild inside Django container, but here I have no idea. I store all code in documents.py. documents.py from elasticsearch_dsl.connections import connections from elasticsearch_dsl import Document, Text connections.create_connection(hosts=['http://elasticsearch:9200']) class FilmWorkDocument(Document): title = Text() description = Text() class Index: name = 'film' FilmWorkDocument.init() first = FilmWorkDocument(title='Example1', description='Example description') first.meta.id = 47 first.save() docker-compose.yml elasticsearch: image: elasticsearch:8.13.0 container_name: elasticsearch environment: - "ES_JAVA_OPTS=-Xms200m -Xmx200m" - discovery.type=single-node - xpack.security.enabled=false ports: - 9200:9200 Sending a request http://localhost:9200 shows that everything is ok. { "name" : "eeb958274241", "cluster_name" : "docker-cluster", "cluster_uuid" : "wUQjIKoLTNGKtFH7A1tzSw", "version" : { "number" : "8.13.0", "build_flavor" : "default", "build_type" : "docker", "build_hash" : "09df99393193b2c53d92899662a8b8b3c55b45cd", "build_date" : "2024-03-22T03:35:46.757803203Z", "build_snapshot" : false, "lucene_version" : "9.10.0", "minimum_wire_compatibility_version" : "7.17.0", "minimum_index_compatibility_version" : "7.0.0" }, "tagline" : "You Know, for Search" } But after … -

I'm getting a 503 error when I upload an image to a pre-trained model and try to get output using python + Django on a shared web host
Background: *Beginner here. * I made a simple app with some basic models and trained it to distinguish happy and sad faces. I made this and ran it in a local development server with Django which worked perfectly and I was even able to display the image after getting a non-logged-in user to upload. Then, I tried uploading the app to a non-local server. This server is part of a shared web hosting package and has cPanel. The app works fine till I upload the image and then it shows a 503 error. The server resource logs show that usage spikes when I upload the image and it is fed into the pre-trained neural network but nothing that would overpower the limits, only 75% of server physical memory being used.

How do I display an image slideshow using Bootstrap Carousel in Django?
I am trying to display a slideshow using Bootstrap Carousel in Django. The idea is to show multiple images in the slideshow for each event detail (attached with a foreign key).

This is an image of where I would like the slideshow to show, but it is not working. admin.py from django.contrib import admin from .models import Person, PersonDetail, Event, EventDetail, EventImage admin.site.register(Person) admin.site.register(PersonDetail) admin.site.register(Event) admin.site.register(EventDetail) admin.site.register(EventImage) models.py from django.db import models class Person(models.Model): person_text = models.CharField(max_length=200) def __str__(self): return self.person_text class PersonDetail(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) person_subtext = models.TextField() def __str__(self): return f"{self.person_subtext[:50]}..." class Event(models.Model): event_text = models.CharField(max_length=200) def __str__(self): return self.event_text class EventDetail(models.Model): event = models.ForeignKey(Event, on_delete=models.CASCADE) event_subtext = models.TextField() def __str__(self): return self.event_subtext class EventImage(models.Model): event = models.ForeignKey(Event, on_delete=models.CASCADE) image = models.ImageField(upload_to='pics/%y/%m/%d/') title = models.CharField(max_length=150) sub_title = models.CharField(max_length=100) def __str__(self): return self.title views.py from django.shortcuts import render from .models import Person, Event, EventImage def index(request): """The home page for History Gallery.""" return render(request, 'galleries/index.html') def persons(request): """Show all persons.""" persons = Person.objects.all() context = {'persons': persons} return render(request, 'galleries/persons.html', context) def person_detail(request, person_id): … -
How can I run tasks in background of djagno project? [duplicate]
I need to run a few tasks in background of my Django project and also I didn't know what is __init__.py file in the Main and App directory in my Django project. I thought myself this file could help me to run my tasks when I run the server with runserver command, But when I'm trying to put some simple codes in this file, I'm facing with this error django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.. My idea is to change my Django database in a scheduled way in background with async functions in django event loop. How can I do that? -

Why uwsgi doesn't disable threads inside django application
Uwsgi docs says, that threads inside an application are turned off until you haven't explicitly turned them on. For me, it works not like that. I have checked it through a simple view in django. uwsgi run params: - uwsgi - --socket=0.0.0.0:8081 - --module=conf.shop.wsgi - --buffer-size=65535 - --py-autoreload=1 - --lazy - --lazy-apps - --vacuum When uwsgi starts, it writes: *** Python threads support is disabled. You can enable it with --enable-threads *** View code: from threading import Thread def view(): def foo(time_sleep, number: int): time.sleep(time_sleep) return number results = {} threads = [] for i in range(8): thread = Thread( target=foo, kwargs={'time_sleep': 1, 'number': i}, name=f'task {i}', ) threads.append(thread) [thread.start() for thread in threads] [thread.join() for thread in threads] performed_threads = [thread for thread in threads if thread.result is not None] for thread in performed_threads: results[thread.name] = thread.result return results But this code works for 1s, not 8s. I tried --strict and many other options, but didn't find why it works in that way. How to turn them off, if it is possible? -

Changes to Django-Parler aren't applied
I'm working on my django project and currently I'm incorporating translations and localization and I have an issue. I used to had defoult language English but now I want it to be Spanish, but for some reason it's still English. Also, with Django-parler, I can see on English side of website with Spanish content even I already selected 'hide_untranslated': True, . Why changes aren't applied? # languages LANGUAGE_CODE = 'es' LANGUAGES = [ ('es', _('Spanish')), ('en', _('English')), ('ar', _('Arabic')), ('tr', _('Turkish')), ] LOCALE_PATHS = [ BASE_DIR / 'locale', ] PARLER_LANGUAGES = { 1: ( {'code': 'es',}, # Spanish {'code': 'en',}, # English {'code': 'ar',}, # Arabic {'code': 'tr',}, # Turkish ), 'default': { 'fallbacks': ['es'], 'hide_untranslated': True, } } Thanks in advance!
