Django link table row to detail view with buttons to other views
Hey thanks in advance for any help its always much appropriated. So I found this post on here that help do this and it worked great. So i have my table and when you click a row it goes to the right detail view for that row. What i would also like to do is have a column in the table with a button for delete and one for edit for each row. I was able to add the buttons but it looks like the JS code that makes the rows clickable is overriding the buttons. without the JS code the buttons work. Any guidance on what to look up or helpful terms to make the rows clickable and and buttons not be lumped into it. Sorry I've very new to this in general and especially inexperienced in javascript I tested with the rows not clickable (no javascript) and the buttons that are in work and go to the intended view. I also tried moving data-href="{% url 'detail' part.pk %}"the tag in the html the Table tag. this made a single cell clicked as expected (not what i want) but the buttons become clickable again but don't route properly.

Error: The invalid form control is not focusable
I'm encountering an issue with my Django form where I'm getting the following error messages in my browser console: The invalid form control with name=‘content’ is not focusable. An invalid form control is not focusable. I'm not sure what's causing this error or how to resolve it. I've checked my HTML form and Django view, but I can't seem to find any obvious issues. Btw, I'm kind of new to both CKEditor and Django, excuse me for any "dumb" requests - I just couldn't find a fix to this.

How can I deploy a Django project with a pickled model in Railway app?
I would like to deploy my Django project on a Railway app, but the server does not find the pickled model. Although I made sure that the file exists in the github repository that I am deploying, Railway app continuously displays this error: from core import views File "/app/core/views.py", line 37, in binary_clf = joblib.load(os.path.abspath('binary_classifier.pkl')) File "/opt/venv/lib/python3.8/site-packages/joblib/numpy_pickle.py", line 650, in load with open(filename, 'rb') as f: FileNotFoundError: [Errno 2] No such file or directory: '/app/binary_classifier.pkl' The thing is, I don't have any static files except for this pickled ML model. But, I tried including the pickled model in a 'static' folder like it was described here, in which case I got this error: from core import views File "/app/core/views.py", line 37, in binary_clf = joblib.load("static/binary_classifier.pkl") File "/opt/venv/lib/python3.8/site-packages/joblib/numpy_pickle.py", line 650, in load with open(filename, 'rb') as f: FileNotFoundError: [Errno 2] No such file or directory: 'static/binary_classifier.pkl' How are we supposed to deploy Django apps when we have pickled files in it? -
Operational Error in Django: Migrating a Python Web Application to a mariadb database

I created a Babylon with meshes loaded in a X Django app template, now I need to rotate it by clicking buttons located a dash-board on a y Django app
I'm using a Babylon in a Django project, created a app template that I have few meshes loaded and I did set buttons to rotate the meshes using addEventListener, it are working well when the UI buttons is located in the same HTML template where the canvas is loaded, APP X.

Javascript request to Python Django not found

Slow response from Django Rest Framework with annotated queryset
I am using Django Rest Framework and simply trying to filter out objects which have more than 0 related items but as soon as I add in a filter to my annotation that includes a datetime, the response time goes from milliseconds to 90 seconds or so. Here is the code that takes ages:- class EventVenueViewSet(viewsets.ReadOnlyModelViewSet): queryset = EventVenue.objects.annotate( num_slots=models.Count( "eventblock__eventslot", filter=Q(eventblock__status='active') & Q( eventblock__eventslot__start_time__gt=timezone.now() + timedelta(days=2) ) ) ).filter(num_slots__gt=0) If I remove the filter that includes the DateTimeField (start_time)... class EventVenueViewSet(viewsets.ReadOnlyModelViewSet): queryset = EventVenue.objects.annotate( num_slots=models.Count( "eventblock__eventslot", filter=Q(eventblock__status='active') ) ).filter(num_slots__gt=0) it is very fast. But the presence of that datetime filter slows it down to the point of being useless. It's nothing to do with db lookups - it's doing 8 of those so that's fine. The SQL query looks fine and the results are correct - it's just taking soooooo long! Any ideas? -

In Django Rest Framework how to make a function base view roll back every change made if somethings fails
I have a api endpoint that the user will send a key pair of file_field: File in the multipart content type. The function need to update every document and create a history about the change.

Difficulty Using gettext_lazy in Django 4 Settings with django-stubs, Resulting in Import Cycle and mypy Type Inference Error
Problem: Mypy Error: The mypy error encountered is as follows: error:Import cycle from Django settings module prevents type inference for 'LANGUAGES' [misc] I'm encountering challenges with the usage of gettext_lazy in Django 4 settings while utilizing django-stubs. The recent update in Django 4 brought changes to the typing of gettext_lazy, where the old return type was str, and the new type is _StrPromise. The issue arises from the fact that _StrPromise is defined in "django-stubs/utils/functional.pyi," and within this file, there is also an import of django.db.model which imports settings. This creates a circular import. current module-version: typing mypy = "1.7" django-stubs = "4.2.7" Django dependencies Django = "4.2.10" Seeking advice on a cleaner and more sustainable solution to the circular import issue and mypy error in the context of Django 4 settings with the updated gettext_lazy typing. Any insights or alternative approaches would be greatly appreciated. possible Solutions: Several solutions have been considered, but none of them are ideal: Disable Mypy Typing for Settings: Disabling Mypy typing for settings is a workaround, but it might compromise the benefits of static typing. Remove gettext_lazy from Settings: Another option is to remove gettext_lazy from settings. However, this contradicts the current recommendations in … -

Why does Django order by column number instead of column name?
I have this Django ORM code: queryset.filter(filters).annotate(rank=SearchRank(vectors, search_query)).order_by('-rank').distinct() and Django transforms this code into that sql: SELECT DISTINCT "model_1"."id", ... ... ... ts_rank( "model_2"."search_vector", phraseto_tsquery(query) ) AS "rank" FROM "model_1" INNER JOIN "model_2" ON ( "model_1"."id" = "model_2"."case_id" ) WHERE ( "model_2"."search_vector" @@ ( phraseto_tsquery(query) ) ) ORDER BY 41 ASC I cant understand why Django use 41(its a number of annotated rank column) instead of column name and i cant find any Django docs that describe this logic.

Celery Task Fails with "Object Does Not Exist" Error Despite Using Auto-Commit in Django
In my Django application, I've encountered a rare issue where a Celery task, invoked via apply_async immediately after creating an object in a model's save method, failed because it could not find the newly created object. This issue has occurred only once, making it particularly puzzling given Django's auto-commit mode, which should commit the new object to the database immediately. Below is a simplified version of the code where the issue appeared: from django.db import models from myapp.tasks import process_new_object class MyModel(models.Model): .... class AnotherModel(models.Model): .... def save(self, *args, **kwargs): new_obj = MyModel.objects.create(name="Newly Created Object") process_new_object.apply_async(args=[new_obj.pk], countdown=5) return super().save(*args, **kwargs) @shared_task def process_new_object(obj_id): try: obj = MyModel.objects.get(pk=obj_id) ... except MyModel.DoesNotExist: pass what might be potential causes for the Celery task to sometimes fail to find the newly created object, despite the delay and Django's auto-commit? -
