Django forms.py and Join.html not rendering form errors

I tried many options including AI yet I was still running into the same problems.

How Can I Setup Celery in my Flask Project (Beginner)
So I've been working on a project for a couple months now and I've been trying to implement Celery into my flask project and it has not gone well. I thought maybe it's my computer or windows or something like, and all the responses I've seen are from a couple years ago and I don't think that they would still work because those were the ones I tried using. So thank you for any responses in advance. I tried using the celery config from the documentation and some chat gpt tutorials but they haven't been of help. And I'm running redis as the broker and result backend on the localhost -

Using React in existing Django Project
I have an existing Django project. Its a website that displays a map with leaflet. Markers and everything is loaded dynamically from django. Now I want to enhance that with React. In a sense that when you click a marker on the map, react will render based on marker_id the specific marker-details in a sidebar or something. I am not sure how to do that. In the django template I have a onclick event to get the marker-details: marker.uri = `/map/api/marker_details/?marker_id=${marker.marker_id}&marker_type=${marker.marker_type}` marker.on('click', function (e) { jQuery.get(this.uri); }); Since this is all in django template and not in React, the result is probably not accessible via react to render the details. Do I have to implement the map with the marker and everything in React to then be able to render the details via API? What am I missing? -

Mixing gzip & brotli in Django
I have django-brotli installed and use it's middleware. I would like Django to also serve gzipped content in case the client doesn't support brotli. Is it as easy as just adding GZipMiddleware to the middlewares list? I don't want them to potentially mix with eachother. -

Django serializer to convert list of dictionary keys to model fields
I am using pandas openpyxl to read excel file in my project. After reading the excel file I end up with list of dictionaries. These dictionaries have keys such as "Year 2024", "Range", "Main Point", and etc. I have a field in my Django app that has these fields such as "year", "range", "main_point". My question is how can I write a serializer to convert dictionary keys to fields in my model? I want to do this in serializer because I also want to validate dictionary data. So I have this list: my_data = [ {"Year 2024": "5", "Range":"2", "Main Point": "OK"}, {"Year 2024": "6", "Range":"3", "Main Point": "OK"}, {"Year 2024": "7", "Range":"4", "Main Point": "OK"}, ... ] and my model class MyModel(models.Model): year = models.IntegerField(...) range = models.IntegerField(...) main_pont = models.CharField(...)

Why I can't install Django channels?
My OS is ubuntu 24.04. I am trying to create a chat application in Django. For that I need django channels and try to install them with pip install channels command. After executing this command I get this error: pip install channels error: externally-managed-environment × This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install. If you wish to install a non-Debian-packaged Python package, create a virtual environment using python3 -m venv path/to/venv. Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make sure you have python3-full installed. If you wish to install a non-Debian packaged Python application, it may be easiest to use pipx install xyz, which will manage a virtual environment for you. Make sure you have pipx installed. See /usr/share/doc/python3.12/README.venv for more information. note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. hint: See PEP 668 for the detailed specification. I just want to install with pip the django channels to use it in chat application. -

Gateway Timeout - The gateway did not receive a timely response from the upstream server or application when running under apache
My django server implements rest apies for excel operations so that user can upload/download data from/to django server's database.

Django tinymce makes all text fields a rich text editor
I am using a DRF as my backend. I configured django parler to manage my translations. I would like to use TinyMCE and normal text fields on the same admin page. This is my model: from django.db import models from parler.models import TranslatedFields, TranslatableModel, TranslatedField from django.utils.translation import gettext as _ from tinymce.models import HTMLField from core.utils import validate_image_size class SportCard(TranslatableModel): sport = models.ForeignKey('Sport', on_delete=models.CASCADE, verbose_name='Sport út') name = TranslatedField(any_language=True) image = models.ImageField(upload_to='media', validators=[validate_image_size]) description = TranslatedField(any_language=True) summary = TranslatedField(any_language=True) translations = TranslatedFields( name=models.CharField(_("name"), max_length=255), description=HTMLField(_("description")), summary=models.TextField(_("summary")), ) def __str__(self): return self.name However on the admin page the models.TextField shows as a TinyMCE: This is the config in my settings.py: TINYMCE_DEFAULT_CONFIG = { 'height': 360, 'width': 800, 'cleanup_on_startup': True, 'custom_undo_redo_levels': 20, 'selector': 'textarea', 'theme': 'silver', 'plugins': ''' textcolor save link image media preview codesample contextmenu table code lists fullscreen insertdatetime nonbreaking contextmenu directionality searchreplace wordcount visualblocks visualchars code fullscreen autolink lists charmap print hr anchor pagebreak ''', 'toolbar1': ''' fullscreen preview bold italic underline | fontselect, fontsizeselect | forecolor backcolor | alignleft alignright | aligncenter alignjustify | indent outdent | bullist numlist table | | link image media | codesample | ''', 'toolbar2': ''' visualblocks visualchars | charmap hr pagebreak …
