Git pull fails with "RPC failed; curl 92 HTTP/2 stream 7 was not closed cleanly: CANCEL (err 8)"
I'm having trouble running git pull from my repository.

How to implement one-way data transfer at specific intervals using SSE or WebSockets?
I'm working on a web application where I need to send data from the server to the client at specific times rather than continuously. I want to achieve this using either Server-Sent Events (SSE) or WebSockets. Requirements: One-way communication: Data only flows from the server to the client. Timing control: Data should be sent only at predefined intervals or specific triggers, not continuously. Questions: Can I use SSE for this purpose, and if so, how would I structure the server to send messages only at specified times? Would using WebSockets be a better approach for sending timed messages? If yes, how would that be implemented? Are there alternative methods (like HTTP polling or long polling) that could suit my needs better? I initially tried using Server-Sent Events (SSE), but I found that it sends data continuously, which isn't what I need. -
Hi, I'm new to the Django. I wanted to know how to bind selected objects to another model object at once on web page (like a checkbox)
I wanted to know how to create a model object by binding multiple other selected objects at once on a web page (like a checkbox or something). For example If I want to create a model named group for university but I need to include students from another model to this group excluding some of them (not all of the given students will be included). So, I was not able to create a form to choose all of them or exclude some of them at once, please help. Thanks in advance. -
Timeout error when uploading PDF and CSV files in Django app on o2switch server
I deployed a Django application on an o2switch server and I am trying to upload files to my media folder. My code works perfectly for .txt and .xlsx files, but it does not work for .pdf or .csv files. I get a timeout error, and it seems that the request does not even reach the server, because nothing appears in the logs. I tried to do a test with a PHP script on the same domain, and it works for all file types. So the problem seems to come either from the Django Rest Framework application, or from a specific configuration on o2switch. As a reminder, uploads work fine with .txt files, but I get a timeout for .pdf and .csv files. Do you have any ideas on what could cause this behavior? Is it a problem related to Django Rest Framework or to the o2switch configuration? and python 3.8.18 Thanks in advance for your help import os import sys sys.path.append(os.getcwd()) os.environ['DJANGO_SETTINGS_MODULE'] = 'Back_end_Gaz_elec.settings' import django.core.handlers.wsgi from django.core.wsgi import get_wsgi_application SCRIPT_NAME = os.getcwd() class PassengerPathInfoFix(object): def __init__(self, app): self.app = app def __call__(self, environ, start_response): from urllib.parse import unquote environ['SCRIPT_NAME'] = SCRIPT_NAME request_uri = unquote(environ['REQUEST_URI']) script_name = unquote(environ.get('SCRIPT_NAME', '')) offset … -

Creating an SPA - use AJAX or django urls?
I am building a website as a school project, which should use django for the backend and vanilla js for the frontend. My question is, for loading different html files, is it better to use AJAX or django urls? I am not sure if using different django urls would make the content load dynamically, as it is required by a SPA. If there is a better way to load my content, please let know. I will really appreciate any help with this. -
Django Wagtail, React Native and 3rd Party Signup and Signin
I'm working on a marketplace platform. My sellers have a web portal to manage their stores. My buyers have a react native mobile application to access the platform. My server is running on django wagtail. I am using django allauth and I'm able to login to my django server from my mobile application. Using username and password and it creates a jwt which my app uses to consume my django api's. However I would like for my mobile users and web portal users to signup using Google and Facebook providers. Using the following two links documentation and doc. I have sort of an idea of the flow. However I'm not clear how to use it with firebase as the examples is directly to the 3rd party provider of github. Based on my research I keep coming across Firebase, how will it play nice with django allauth social? And will my web portal and mobile app need different integration methods? I came across this post but the answer doesn't seem complete because if Django doesn't have anything to do with this flow how will it know a user is authorised to consume my API's? -
Access Denied while sending email from AWS SES in ElasticBeanstalk (Django application)
I have recently (noticed) that I'm getting the following error in my Django application running on AWS An error occurred (AccessDenied) when calling the GetSendQuota operation: User: arn:aws:iam::123412341234:user/USER-IAM-NAME is not authorized to perform: ses:GetSendQuota with an explicit deny in an identity-based policy My user has full SES access via the direct policy AmazonSESFullAccess.

What is the best option for Django+Celery in Google Cloud run?
We currently have an application which runs in Django and background tasks are in Celery. Now, we need to move to Google Cloud Run, and how to Celery in that case, since celery can not be run in Google cloud run (because it is serverless). I have background tasks like generate video (which may take around 10 minutes) and like generate image, and also sending requests to other services asynchronously. For sending asynchronous request to other services, I used Google Tasks, but the functions for generating video is in my service actually, but Google Task requires to send in this format: "http_request": { 'http_method': tasks_v2:HttpMethod.POST, 'url': url } Is there something that I need to put my function just in background task as celery does simply? What will be the best option for my case to use for background tasks? -

Django returns "Authentication credentials were not provided" when I attempt token authentication
(I tried the solutions in similar questions, but they didn't work for me). I am creating a simple Django REST based web-app, where a user will register, create some events, log in later and view events. Here's the event's view: class EventGetCreate(APIView): authentication_classes = (TokenAuthentication,) permission_classes = (IsAuthenticated,) def get(self, request): created_user = request.user events = Event.objects.filter(creator=created_user) serializer = EventSummary(events, many=True) return Response(serializer.data) Its urls.py is as below: from django.urls import path, include from . import views app_name = 'event' urlpatterns = [ ... path('eventviewall/', views.EventGetCreate.as_view()), ] In core/urls.py, I have this to obtain the token: from .views import UserViewSet from rest_framework.authtoken.views import ObtainAuthToken, obtain_auth_token app_name = 'core' router = routers.DefaultRouter() router.register('users', UserViewSet) urlpatterns = [ path('auth/', obtain_auth_token), path('register/', include(router.urls)), ] Using postman, I can login successfully and get the token: Send request to http://127.0.0.1:8000/api/auth/ and get the following (example token): { "token": "xxyyzz" } Now what I want to do is to send this token in a get request, and view the events the user created.

Django: Favicon Not Displaying for Extracted Link Previews
I'm developing a Django application where users can create blog posts that include links. I want to display a preview of these links, including the website's favicon. However, despite implementing the logic to extract the favicon from the linked websites, it doesn't show up in the frontend. Here’s what I’ve implemented: Model Definition: I have a BlogPost model that includes a title, content, and a timestamp. from django.db import models class BlogPost(models.Model): title = models.CharField(max_length=200) content = models.TextField() created_at = models.DateTimeField(auto_now_add=True, null=True) def get_link_previews(self): links = extract_links(self.content) previews = [] for url in links: previews.append(fetch_link_preview(url)) return previews Link Extraction Logic: I use regex to extract links from the blog post content. import re def extract_links(text): url_pattern = r'https?://[^\s]+' return re.findall(url_pattern, text) Preview Extraction Logic: I use requests and BeautifulSoup to extract the title, description, image, and favicon from the linked page. import requests from bs4 import BeautifulSoup def fetch_link_preview(url): try: response = requests.get(url) soup = BeautifulSoup(response.content, 'html.parser') title = soup.title.string if soup.title else 'No Title' description = soup.find('meta', attrs={'name': 'description'}) description_content = description['content'] if description else 'No Description' image = soup.find('meta', attrs={'property': 'og:image'}) image_content = image['content'] if image else None # Find the favicon favicon_url = None for link in … -

PyCharm autocomplete not working for context variables in Django templates
Normally, PyCharm autocomplete (code completion) works for context variables in Django templates. For example, if the context is {"question": question}, where question is an instance of the Question model, PyCharm will offer autocomplete suggestions when I start typing {{ question. }}, like this: However, in my current Django project, PyCharm autocomplete fails to work for context variables in Django templates. Even pressing Ctrl + Space will not bring up code completion suggestions: I think that I have everything configured in PyCharm for Django as usual for this project, although I could be mistaken. It's a larger project, so I suspect that something about the project structure itself might be causing the problem. Other convenience features are still working in Django templates, e.g., Emmet abbreviations, auto-closing of {{ and {%, etc. At first, I suspected the problem was that I have the models, views, etc., split out into multiple files. For example, instead of all models being contained in a single models.py file, the models are organized like this: models/ __init__.py model_a.py model_b.py model_c.py However, I don't think this is causing the autocomplete failure, because when I created a small Django project and organized it this way, autocomplete still worked for … -

Django Postgres Json Filtering
there is a django model Model. It has a JSONField type field. There are approximately 1000 json files in postgresql in the table of this model. Json has a strict structure. 'food' -> foodid -> 'field' -> fieldname -> {....}. There can be arbitrary values instead of foodid and fieldname. How do I get unique possible pairs (foodid, fieldname) from postgres? Model.objects.annotate( foodid=Func( F('food'), function='jsonb_object_keys', output_field=models.CharField() ) ).annotate( field_name=Func( Value('food__') + F('foodid') + Value('__field'), function='jsonb_object_keys', output_field=models.CharField() ) ).values_list('food_id', 'field_names') The first annotate works. In the second annotate, I want to take the food_id field from the first annotate, but simply specifying F('foodidid__field'), the postgres will look for the foodid field in the table itself which does not exist. -
Django Error: DisallowedHost - Invalid HTTP_HOST header when using custom domain from Namecheap

Authentication Cookie Not Sent with Axios Request in Browser
I'm having trouble with cookie-based authentication in my Django + React app. I've set the cookie on the backend, but it's not being sent with subsequent requests from the frontend React (Using Vite) app running on Google Chrome. I'm trying to implement authentication using cookies in a Django backend using Simple JWT. After a successful login, I set an authentication cookie ("CAT") in Django. Here’s the code I use to set the cookie: final_response.set_cookie( "CAT", combined_token, httponly=True, secure=False, samesite="None", max_age=86400, path="/", ) return final_response Setting.py at the Django server: CORS_ALLOW_ALL_ORIGINS = False CORS_ALLOWED_ORIGINS = ["http://localhost:5173/"] CORS_ALLOW_CREDENTIALS = True SECURE_CROSS_ORIGIN_OPENER_POLICY = "same-origin" I can see the cookie stored in Chrome after logging in: However, when my React app makes subsequent requests, the browser doesn’t seem to include the cookie, and I get an authentication failure ("Cookie not found").

Products Not Filtering Correctly with AJAX in Django
I'm working on an e-commerce website using Django and jQuery to filter products based on selected criteria (price range, categories, and vendors).

Add primary key for existing table
I have database table core_config and basic model core.Config model connected to it. Initial migration has definition of id AutoField as default, but there is no PRIMARY KEY in database table (I have no idea why), so I can't create relations to it from another tables. Is there any ways to generate migration like 'add_constraint_pk_if_not_exists'? I want to make it with "if_not_exists" because there is a probability of existing PRIMARY KEY in other database mirrors.
