Getting a use a thread or sync_to_async error
So Im working on a Django web chat. I just switched my db structure to be able to support groupchats. I changed the code so far and Im struggling to figure out how to fix the following error. django.core.exceptions.SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async. And here's my websocket_connect from consumers.py async def websocket_connect(self, event): print('connected', event) user = self.scope['user'] print(user.online) threads = Thread.objects.filter(participant__user=user).prefetch_related() for thread in threads: chat_room = f'user_chatroom_{thread.id}' self.chat_room = chat_room await self.channel_layer.group_add( chat_room, self.channel_name ) await self.send({ 'type': 'websocket.accept' }) I am happy for every answer! I tried to change the threads variable but I cannot change this since I need it. -

Django: Confusion with accessing database model's foreign key data
This is my first time working with Django and while working I have encountered with a confusion to create a particular statement in views that leads to my desired output. I have created a model 'Parents' which has data of a specific student (Foreign Key), and I am confused to access that student id for further process like working with Attendance, or Results of that specific student.

nginx giving 502 Bad Gateway
I'm following this tutorial (with this repository) to deploy my Django project. I added nginx configuration as described, with all the files and directories seeming to match. The project I'm trying to deploy also has other dependencies like celery or selenium, but those work okay with docker-compose. When I run docker-compose up the app seems to start without errors (celery tasks are executed, etc.), and the proxy gives this log: suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: using the "epoll" event method suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: nginx/1.23.3 suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: built by gcc 12.2.1 20220924 (Alpine 12.2.1_git20220924-r4) suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: OS: Linux 5.15.49-linuxkit suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: getrlimit(RLIMIT_NOFILE): 1048576:1048576 suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: start worker processes suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: start worker process 9 suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: start worker process 10 suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: start worker process 11 suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: start worker process 12 suii-proxy-1 | 2023/01/26 08:43:00 [notice] 8#8: start worker process 13 But when trying to access to http://127.0.0.1 I get a 502 Bad Gateway like this: With this log error: suii-proxy-1 | 2023/01/27 07:10:28 … -

Getting photo url in Django backend and displaying the photo in React frontend
I'm trying to get the url of my photos in the Django backend and send it to the react frontend using axios. I got the url printed in the console in the frontend but when I put the url as a src in an img tag, the image shows up as a blue question mark. What am I missing? Initially it was a cors error, I changed my backend configurations and even disabled cors on safari but nothing worked. I made the photo shareable and tried hard coding the link and that also didn't work. I think I'm supposed to pass the oauth to the frontend as well but I'm not exactly sure how -
Django: converting view function to class-based view. Error during login to Admin panel: matching query does not exist
I'm learning how to convert old view.py functions to class-based views. I started with a simple function that displayed a page with my essays, plus, I had a newsletter form and a draft of a comment form (but not attached to DB). I decided to not develop this comment form further in a simple function, but to rebuild all of it to class-based view to learn a better and cleaner approach. I've encountered a problem that I have no idea how to solve. Error: matching query does not exist. And Exception Value: EssayCls matching query does not exist. Most likely I break the logic that connects my model to my DB. I'm looking for suggestions on how to solve issues in my code and suggestions about topics I should learn more about to make this kind of development less cumbersome. Before I rebuild my view, things were working fine and looked like this: views.py: from django_user_agents.utils import get_user_agent from .models import EssayCls, SendMeMessage from .forms import CommentForm def my_essays(request, home_view_author_slug): user_agent = get_user_agent(request) try: selected_essay = EssayCls.objects.get(slug=home_view_author_slug) if request.method == 'GET': user_feeDBack = UserFeeDBack() else: """ The incoming request from Django will have a POST property which contains any submitted … -

Django query __startswith is not case sensitive

How to aggregate over Django Jsonfield values?

Handling user images in a web app - format, rotate?
everyone, in my web app (Python - Django) users should be able to upload pictures in the future, which will then be displayed in their own profile (like a Facebook picture post). Accordingly, there will be a file input in which the user can select his image. The image must then be displayed directly, as the user may want to upload several images. Since I'm not familiar with image editing, I'm asking myself a few questions. Currently I send the image to my server via Ajax, compress it and scale it to 400x400 px. if the picture doesn't fit the format, i crop it accordingly, certainly not the prettiest option, because if it doesn't fit, i crop from the middle. Then I save the image, and return the URL and render it. Everything works as desired, I'm just not sure if it's really good. For example, how do I deal with images in landscape format? How do I let the user rotate the picture? For this I would have to save it unchanged, render it and then ask the user? How can I open the "Open camera" function for smartphones? Is this possible in a "normal" mobile website version (or … -

How can I implement polling the table and keep the filter applied to it? [Django-filter] [HTMX]
I need to filter my database while live updating it too. However, the current rendering doubles the form and resets the filter to show all the data. How can I filter my data and update it at the same time filter my data and update it at the same time filters.py import django_filters from django_filters import DateFilter from .models import CheckingStatus, Participant from django.db.models import Q class ParticipantFilter(django_filters.FilterSet): class Meta: model = Participant fields = '__all__' views.py def display_view(request): myFilter = ParticipantFilter(request.GET, queryset=Participant.objects.all()) data = myFilter.qs return render(request, 'display.html', {'data': data, 'myFilter': myFilter}) HTML <body> <form method ="get"> {{myFilter.form}} <button class "btn btn-primary" type = "Submit"></button> </form> <br><br> <div id="table-results" hx-get="/display" hx-trigger="every 2s"> <table border="1" class="table table-dark table-hover"> <thead> <th>First_name</th> <th>Last_name</th> <th>Age</th> <th>Checking Status</th> <th>Time</th> <th>Date</th> </thead> {% for k in data %} <tr> <td>{{k.first_name}}</td> <td>{{k.last_name}}</td> <td>{{k.age}}</td> <td>{{k.checking.checking_status}}</td> <td>{{k.checking.time}}</td> <td>{{k.checking.date}}</td> </tr> {% endfor %} </table> </div> </body> Thanks for your time -
How to create model's tables in MySQL?
I'm trying to replicate a PHP/Symfony project in Python/Django as a python learning exercise. Platform = Windows 10. The expected result is that a migrate command will add tables related to all of the entries in settings.py INSTALLED_APPS{...}. Instead, the migrate command adds all Django tables but none of the tables of models.py. What, then, must be done to allow migrate to add the 5 MySQL tables? Result: mysql> use diet_py; Database changed mysql> show tables; +----------------------------+ | Tables_in_diet_py | +----------------------------+ | auth_group | | auth_group_permissions | | auth_permission | | auth_user | | auth_user_groups | | auth_user_user_permissions | | django_admin_log | | django_content_type | | django_migrations | | django_session | +----------------------------+ Following Django tutorial documentation, with slight modifications, I have these directories & files: Tree: ...DB1-PROJECT │ db.sqlite3 │ manage.py │ ├───diet │ │ admin.py │ │ apps.py │ │ models.py │ │ tests.py │ │ views.py │ │ __init__.py │ │ │ ├───migrations │ │ │ __init__.py │ │ │ │ │ └───__pycache__ │ │ __init__.cpython-311.pyc │ │ │ └───__pycache__ │ admin.cpython-311.pyc │ apps.cpython-311.pyc │ models.cpython-311.pyc │ __init__.cpython-311.pyc │ └───mysite │ asgi.py │ settings.py │ urls.py │ wsgi.py │ __init__.py │ └───__pycache__ settings.cpython-311.pyc urls.cpython-311.pyc wsgi.cpython-311.pyc __init__.cpython-311.pyc ..\diet\models.py from … -
How to represent SVG polygon in HTML using deffinition coming from POSTGIS ST_AsSVG function
In my django app I have postgis database. I tried to get a polygon as a SVG, so I could represent that polygon in HTML using the SVG standard. I use the following query: SELECT ST_AsSVG(geom) from country_limit cl where cl.id=3; And It returned the following result: M -85.941653 -12.285635 L -85.941653 -12.291673 -85.927577 -12.291673 -85.927577 -12.285635 Z But when I try to represent that result inside an SVG, in HTML, It does not display the polygon. Here is my code. <svg height="210" width="400"> <path d="M -85.941653 -12.285635 L -85.941653 -12.291673 -85.927577 -12.291673 -85.927577 -12.285635 Z" /> </svg> How can I use the result from postgis ST_AsSVG to represent a geometry as SVG in HTML -
