http://127.0.0.1:8000/ This site can’t be reached127.0.0.1 refused to connect
I created my program in pycharm. It is a series of questions for the user that adds their inputs and get a result from it, pretty basic stuff. I want to share the program with my colleagues, but they are not interested in the coding part, they want to see how it works. So I thought did a little research and decided to test Django. I installed django 4.2.10 and followed chatgtp's steps. Now I have the following folders and files: HYSPI_project/ |-- HYSPI_app/ # Your Django app |-- HYSPI_project/ # Your Django project folder | |-- __init__.py | |-- asgi.py | |-- settings.py | |-- urls.py | |-- wsgi.py |-- db.sqlite3 |-- manage.py |-- python Everything looks good, but when I run python manage.py runserver, the only thing that happens is that my program starts, in bash (mamba). If I try to open http://127.0.0.1:8000 in the browser it says the site cannot be reached. I have verified everything, connection, firewall, and all suggestions from chatgpt. Maybe the problem is in one of my files, manage.py, urls.py, settings.py, but when I ask chatgpt it always says that everything looks ok, and asks me for more information on the error when … -

django migrate with clickhouse
I have a project with two databases: PostgreSQL and Clickhouse. To interact with Clickhouse, I use the django-clickhouse-backend lib. For a long time, I did not use the created migrations for this database, but created tables using raw SQL. Now it's time to apply all the previous migrations, but I ran into a problem. To avoid all conflicts, I had to significantly edit the existing migration files, after that I locally modeled and checked the application of these migrations in the existing database and everything was OK. But when I tried to apply these migrations on the production server, I got the following error: # python manage.py migrate --database clickhouse --fake-initial Operations to perform: Apply all migrations: admin, auth, authtoken, celery_app, contenttypes, django_dramatiq, edl, sessions, users Running migrations: Applying contenttypes.0001_initial...Traceback (most recent call last): File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/dbapi/cursor.py", line 111, in execute response = execute( ^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/clickhouse_backend/driver/client.py", line 53, in execute rv = self.process_ordinary_query( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/client.py", line 571, in process_ordinary_query return self.receive_result(with_column_types=with_column_types, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/client.py", line 204, in receive_result return result.get_result() ^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/result.py", line 50, in get_result for packet in self.packet_generator: File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/client.py", line 220, in packet_generator packet = self.receive_packet() ^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/client.py", line 237, in receive_packet raise packet.exception … -
Upload issue in Django
Please can someone help with an issue i'm having in Django? I've created a recipe app for a course project and want the user to upload images. I've set the model up and when I upload an image from the django admin page it works perfectly, however when I try and upload an image from the user interface, it doesn't work and it should be using the same model. The other CharField, TextField and IntergerField all work but not the ImageField and I don't know why. There is also a default no_picture.jpg however it doesn't use that either. when the Img works the url shows as and when it doesn't the /recipes/ is missing from the URL However I don't think there is an issue with my urlpatterns as the other data works its just the image. Here is the models.py class Recipe(models.Model): name = models.CharField(max_length = 120) cooking_time = models.IntegerField(help_text = 'in mintues', default = 0 ) ingredients = models.CharField(max_length = 300) description = models.TextField() pictures = models.ImageField(upload_to = 'recipes', default = 'no_picture.jpg') forms.py class CreateRecipeForm(forms.Form): name = forms.CharField(max_length=50, required=False) cooking_time = forms.IntegerField(help_text='in minutes', required=False) ingredients = forms.CharField(max_length=300, required=False) description = forms.CharField(max_length=500, required=False) pictures = forms.ImageField(required=False) views.py @login_required def … -

Django Fulltext search is very slow how to make it fast?
I possess an extensive database of products and aim to implement full-text search functionality to enable users to easily search for products.

Django: Handling Expired API Keys Without Signals
Title: Django: Handling Expired API Keys Without Signals Question: How can I implement a logic in Django to automatically delete expired API keys from the OutstandingKey model and update the corresponding BlacklistedKey entry when the expiry date has passed, without using signals? I have two Django models: OutstandingKey and BlacklistedKey. The OutstandingKey model represents API keys generated by users, including an expiry date field. The BlacklistedKey model stores blacklisted API keys, referencing the OutstandingKey through a one-to-one relationship. I want to create a system where expired API keys are automatically removed from the OutstandingKey model and added to the BlacklistedKey model when their expiry date has passed. However, I prefer not to use signals for this implementation due to this Django Anti-Pattern. Could someone provide a blueprint or example of how to achieve this logic within Django?. Below is my Models from django.db import models from django.conf import settings from django.utils import timezone class OutstandingKey(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, null=True, blank=True, default=None, verbose_name="User", ) name = models.CharField(max_length=1000, default="", blank=True, null=True) api_key = models.CharField( max_length=1000, unique=True, verbose_name="API Key", default="", blank=True, null=True, editable=False, ) expiry_date = models.DateTimeField( default=None, verbose_name="Expiry Date", blank=True, null=True ) timestamp = models.DateTimeField(auto_now_add=True) def __str__(self): return self.name class … -

Heroku logging for django management commands
I would like to log statements when running a Django management command on Heroku. So, for example, when I login to Heroku and run the command: heroku run bash python manage.py my_management_command I should see all of the logging.info statements included. But instead they don't appear in the Heroku logs. All logging.info statements from the normal django appear fine, just not when I run a management command. My logger setup in settings.py is as follows: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', 'formatter': 'verbose', }, }, 'loggers': { 'mylogger': { 'handlers': ['console'], 'level': 'DEBUG', 'propagate': True, }, }, 'formatters': { 'verbose': { 'format': '%(asctime)s - %(name)s - %(levelname)s - %(message)s' }, }, } Can anyone tell me how to get log statements from inside my django management command to appear in the heroku logs? -

However, I am unable to resolve this error when I start the development server: Traceback (most recent call last): File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/threading.py", line 932, in _bootstrap_inner self.run() File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/threading.py", line 870, in run self._target(*self._args, **self._kwargs) File "/Users/chanakgautam/PycharmProjects/djangoProject/venv/lib/python3.8/site-packages/django/utils/autoreload.py", line 64, in wrapper fn(*args, **kwargs) File "/Users/chanakgautam/PycharmProjects/djangoProject/venv/lib/python3.8/site-packages/django/core/management/commands/runserver.py", line 125, in inner_run autoreload.raise_last_exception() File "/Users/chanakgautam/PycharmProjects/djangoProject/venv/lib/python3.8/site-packages/django/utils/autoreload.py", line 87, in raise_last_exception raise _exception[1] File "/Users/chanakgautam/PycharmProjects/djangoProject/venv/lib/python3.8/site-packages/django/core/management/__init__.py", line 394, in execute autoreload.check_errors(django.setup)() File "/Users/chanakgautam/PycharmProjects/djangoProject/venv/lib/python3.8/site-packages/django/utils/autoreload.py", line 64, in wrapper fn(*args, **kwargs) File "/Users/chanakgautam/PycharmProjects/djangoProject/venv/lib/python3.8/site-packages/django/__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "/Users/chanakgautam/PycharmProjects/djangoProject/venv/lib/python3.8/site-packages/django/apps/registry.py", line 91, in populate app_config = AppConfig.create(entry) File "/Users/chanakgautam/PycharmProjects/djangoProject/venv/lib/python3.8/site-packages/django/apps/config.py", line 193, in create import_module(entry) File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1014, in _gcd_import File "<frozen importlib._bootstrap>", line 991, in _find_and_load File "<frozen importlib._bootstrap>", line 973, in _find_and_load_unlocked ModuleNotFoundError: No module named 'scraper_app' Based off previous posts I've read, I suspected the issue could lie in my file structuring.

How to Embed google review in Django website?
I was going through the Google Cloud Platform Console to find out how I could embed a Google review on my Django website. I found the Google Places API to be the most relevant (not quite sure), but then I got lost with all the details, pricing, and different tiers. My case is actually quite simple. I just want to display the total number of stars a specific place has. Is there a free way to get that, which I didn't understand? -
Portable windows app built with electron-builder takes too long to start up
I have used electron-builder to package my React + Django application into a single executable file. When I build the app, the resulting dist folder contains: -- dist (folder generated after building the app with electron) | |- MyApp0.0.1.exe (portable exe file) | |- win-unpacked | | | |-MyApp.exe | |-multiple_folders (dependencies of the MyApp.exe) | |-multiple_files (dependencies of the MyApp.exe) The problem is the following: When runnning the MyApp.exe inside the win-unpacked folder, and as long as the dependency files/folders are at the same level, the app works perfectly fine and takes less than a second to startup and display. It even asks for admin password, as in the package.json config it is specified to build it with "requestedExecutionLevel": "highestAvailable". When running the MyApp0.0.1.exe which is supposed to be the portable, standalone .exe file for the application, although it does run perfectly fine, it takes up to 6 minutes to start-up and display the app. I have tried skimming down the project as much as possible in terms of the node_modules that I need, removing large data files not needed, ... I am clueless as to why this is happening. I am not a web-dev expert in any way … -
Custom Admin Site in Django
I have problem to change title_header, site_header, index_title in custom admin site. My admin.py: from reviews.models import Movie, MovieCasts, Review, Actor class CritiflixAdminSite(AdminSite): title_header = 'Aplikacja administracyjna Critiflix' site_header = 'Aplikacja administracyjna Critiflix' index_title = 'Administracja witryną Critiflix' movie_admin_site = CritiflixAdminSite(name='critiflix') movie_admin_site.register(Movie) movie_admin_site.register(MovieCasts) movie_admin_site.register(Review) movie_admin_site.register(Actor) My urls.py: from django.urls import include, path from . import views urlpatterns = [ path('admin/', movie_admin_site.urls), path('movies/', views.movie_list, name = 'movie_list'), path('movies/<int:pk>', views.movie_detail, name = 'movie_detail'), path('', views.base, name = 'base') ] When i run manage.py nothing is change and models aren't on panel. -
Sending and receiving custom signals in Django and ensuring it is atomic
I want to create a custom signal and send the signal after some database operations. The receiver also performs database operations. I want to make sure all the database operations before sending the signal and in the signal, receiver is atomic meaning either all fail, or all succeed. Consider the following code: def send_my_signal(): # Database operation 1 # Database Operation 2 my_signal.send(sender=MyModel) The receiver: @receiver(my_signal) def my_receiver(sender, **kwargs): # Database operation 3 # Database operation 4 I want either all database operations 1 to 4 succeed or fail together. By asking from generative AI models, one proposed solution is to wrap the body of the function that performs database operations and sends the signal inside the transaction.atomic() context manager. So, the code would look like this: def send_my_signal(): with transaction.atomic(): # Database operation 1 # Database Operation 2 my_signal.send(sender=MyModel) But I could not find any resource or anything in Django documentation confirming this. It's not like I am calling the receiver of the signal inside the transaction.atomic() context manager, I am just sending the signal there.
