Django 4.2.2 not respecting STORAGES['default']['BACKEND']
Using settings.py: STORAGES = { "staticfiles": { "BACKEND": "storages.backends.s3boto3.S3Boto3Storage", }, "mediafiles": { "BACKEND": "storages.backends.s3boto3.S3Boto3Storage", }, "default": { "BACKEND": "storages.backends.s3boto3.S3Boto3Storage", }, } and running: from django.conf import settings print('settings.DEFAULT_FILE_STORAGE', settings.DEFAULT_FILE_STORAGE) prints: settings.DEFAULT_FILE_STORAGE django.core.files.storage.FileSystemStorage Media is writing to local and not S3 and this must be why. Static, for some reason, writes to S3 no problem. Any help or ideas would be appreciated. The full codebase can be seen here: https://github.com/rkuykendall/Simplici7y -
Is Using Psycopg2 with Django Ok?
I prefer using Psycopg2 over Django's built-in database handling system. Are there any major disadvantages to this? Would this not work well with larger-scale projects? Are there any important features that I would be missing out on this way? -
Validate a model instance for unique drf
I am working on a "Recipes" model and I want to prevent the creation of duplicate models with the same fields. Specifically, I want to throw a validation error if a model instance already exists with the same field values. This is my current code: def validate_recipe(self, value): recipes = Recipe.objects.all().filter(author=self.context['request'].user) for rec in recipes: if rec._meta.fields == value._meta.fields: raise serializers.ValidationError( {'errors': 'Do you have this recipe!'} ) return value Here are the images of the output I am currently getting: enter image description here enter image description here -
Dynamically scheduled tasks
I successfully configured Celery on my Django app and tested it. The test run was successful, as shown by the following output: celery -A concentrApp call mytask 0016f381-ed04-4a44-8c7a-c091a66dce0a [2023-06-17 13:46:28,465: INFO/MainProcess] Task mytask[0016f381-ed04-4a44-8c7a-c091a66dce0a] received [2023-06-17 13:46:28,477: INFO/ForkPoolWorker-8] Task mytask[0016f381-ed04-4a44-8c7a-c091a66dce0a] succeeded in 0.009182458000005056s: None ` Now, I would like to take this a step further and make the task dynamic. My goal is to create an endpoint that accepts parameters such as time, and param, and then run the task every sunday-thursday in the given hour using the provided parameter. This will allow me to customize the task execution based on user input, and make it several times that the user want. Thank you -

DJANGO: I have genres in my database, and django doesnt display them in my page('shop.html') even though i used loop
I am trying to modify a Django website. One of the webpages lists video games. Each game has a genre property, and I want to allow the user to filter the games based on their genres. However, each game can have multiple genres. Therefore, I created a Genre model that has a "title" property, and each Game has a many-to-many relationship with genres. I have already created the Genre model and created a page that lists all the existing genres. Now I want to create a page that lists all the games that have a certain genre. Here is my code below: in models.py class Genre(models.Model): title = models.CharField(max_length=255, verbose_name='Название жанра') def __str__(self): return self.title in views.py def shop_page(request): return render(request, 'store/shop.html') def genre_page(request, pk): genre = Genre.objects.get(pk=pk) genres = Genre.objects.all() games = Game.objects.filter(genres=genre) context = { # 'genre': genre, 'genres': genres, 'games': games } return render(request, 'store/shop.html', context) in urls.py path('shop/', shop_page, name='shop_page'), path('genre/', genre_page, name='genre'), in shop.html <ul class="trending-filter"> <li> {% for genre in genres %} <a class="is_active" href="{% url 'genre' genre.pk %}" data-filter="*">{{ genre.title }}</a> {% endfor %} </li> </ul> -
How can I use skfuzzy in Django?
I have created a Django project and I want to implement a simple fuzzy logic with three inputs and one output. However, when I import "skfuzzy" in Django views and reload the page, I get a Gateway Timeout error after 2 minutes (even without any implementation, just importing "skfuzzy"). I have run "pip3 install scikit-fuzzy" in the project virtual environment, and everything seems to be working fine. The code runs without a problem in the terminal, but it doesn't work in the Django project. Why is this happening? -
Django filter a model in the template
I want to be able to filter a model in the template (or find a different solution to fix my problem). The relevant models look like this: class CommissionElection(models.Model): title = models.CharField(max_length=64) commission = models.ManyToManyField(Commissie, related_name="elections") class ElectablePerson(models.Model): commission = models.CharField(max_length=128) election = models.ManyToManyField(CommissionElection, related_name="electables") class Commissie(models.Model): commissie = models.CharField(max_length=64) Here Commissie is a model from a different app. I have created a page for a specific election, now I want on that page a list per commission which states all the ElectablePersons that stated themselves electable for that commission (and for that election). I tried the following in my template: {% for commission in election.commission.all %} {{ commission }} {% for electable in election.electables.filter(commission=commission) %} {{ electable}} {% endfor %} {% endfor %} This gives the error Could not parse the remainder: '(commission=commission)' from 'election.electables.filter(commission=commission)' Is there anyway I could filter the model in the template or is there a different way I could do this? -

Is it possible to use update_state and progress_observer within a function executed by a Celery task instead of directly inside the task itself?
I am developing a Django app that browses a website, selects a comic, and downloads it in the background with Celery. In the task.py file, I have a download_comic() function decorated with @shared_task(). The function checks the URL's hostname and uses different child classes of the base class FileHost to download the file. The actual download is done inside the class method, not on the task function. I came across this article (https://buildwithdjango.com/blog/post/celery-progress-bars/) that suggested using task.update_state and progress_observer.set_progress for progress monitoring. However, I am not sure if I can use these functions inside a class method or not. Here's a snippet of the FileHost class and download() method for reference: class FileHost: def __init__(self, url): self.url = url r = requests.get(self.url) self.soup = BeautifulSoup(r.content, "html.parser") def download_file(self): # Implement the file download logic here raise NotImplementedError() def download(self, filename, direct_link): response = requests.get(direct_link, stream=True) temp_path = Path('/tmp') / filename if 'Content-Disposition' in response.headers: content_disposition = response.headers['Content-Disposition'] temp_path = Path('/tmp') / content_disposition.split("=", -1)[-1] if response.status_code == 200: total_size = int(response.headers.get('content-length', 0)) downloaded_size = 0 with open(temp_path, "wb") as file: for chunk in response.iter_content(chunk_size=4096): if chunk: file.write(chunk) downloaded_size += len(chunk) # Calculate the progress percentage progress = int((downloaded_size / total_size) * … -

Customizing Django viewflow url
I am using the django-viewflow application with a custom view representing a stock item record where there are a number of workflows that can be attached to the record (registering/ issuing/ disposing etc.). In the detail view of the record I want to have a list of all workflows attached to the item and to be able to list all the tasks related to that workflow. I am aiming for a url that looks like .../asset/3/ - for the detail view .../asset/3/register/93/ - for the register process (and subsequent tasks) .../asset/3/movement/1/ - for movement process (and subsequent tasks) etc My application url.py looks like: asset_urls = FlowViewSet(AssetFlow).urls movement_urls = FlowViewSet(MovementFlow).urls app_name = 'asset' workflowurlpatterns = [ # path('ajax/load-budget_lines/', views.load_budget_lines, name='ajax_load_budget_lines'), path('viewflow/', include((asset_urls, 'asset'))), path('movement/', include((movement_urls, 'movement'))), # path('', views.Detail.as_view(), name='detail'), ] urlpatterns = [ path('', views.List.as_view(), name='assets'), path('<int:asset_pk>/', views.Detail.as_view(), name='detail'), path('<int:asset_pk>/', include((workflowurlpatterns))) ] The issue is that all the urls generated by the template tag {% flowurl task user=request.user as task_url %} fail with a NoReverseMatch error. Is there a clever way to pass the asset_id so that the urls work (or another solution)? -

Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?" What should I do to get this working? -
Why do multiple test files cause Django issues when running in parallel?
I am using django 4.1 on windows. running my tests sequentially (python manage.py test) works fine. but when I run my tests in parallel (python manage.py test --parallel) I get the following error File "C:\Users\SomeGuy\miniconda3\envs\SomeProject\lib\multiprocessing\process.py", line 315, in _bootstrap self.run() File "C:\Users\SomeGuy\miniconda3\envs\SomeProject\lib\multiprocessing\process.py", line 108, in run self._target(*self._args, **self._kwargs) File "C:\Users\SomeGuy\miniconda3\envs\SomeProject\lib\multiprocessing\pool.py", line 109, in worker initializer(*initargs) File "C:\Users\SomeGuy\miniconda3\envs\SomeProject\lib\site-packages\django\test\runner.py", line 420, in _init_worker process_setup(*process_setup_args) TypeError: process_setup() missing 1 required positional argument: 'self' I created a project and made a folder underneath the main app folder for my tests called "tests" next to manage.py I have two test files test_losing_hair.py: from django.test import TestCase class WhyTest(TestCase): def test_counting_scheme(self): self.assertTrue(True) and test_rapidly.py: from django.test import TestCase class WontThisWorkTest(TestCase): def test_counting_scheme(self): self.assertTrue(True) What Am I doing wrong here? I've noticed running it in parallel works if I choose one file or the other, but both at the same time creates the error above.
