A method called within the below method triggers mypy to lint with test_get_all_boards: test_get_all_boards invalid syntax mypy(error). The method in question returns a boolean.

Django: sorting querysets to have a specific order of objects
I've a model with two fields, say deprecated and new. When I'm listing the objects, I'd like the ones with new=True at the beginning, followed by the objects where deprecated=True and then the rest. I've seen a bunch of answers about ordering by multiple fields but that doesn't seem to work for me. This is how I'm doing the ordering now: class Meta: ordering = ['new', 'deprecated'] I've tried using multiple order_by on the queryset as well but that doesn't do the trick either. Right now I get a list with the new ones at the beginning butthe deprecated ones at the bottom. Is there a direct way to do what I want? This doesn't work for me as the order should be based on fields rather than specific ids. -

How to list the titles of html pages with links on the home page in Django
Picture of my window I am sorry if this is a stupid question but I am new to Django. I am building a website and I have articles saved as template files. I want to display all of their titles with links directed to those templates but I want to automatically list them so if I add a new template to the folder, the home page will have the new link to that template.

javascript onclick function not working in django template (problem most certainly is with the js code, i have verified the correctness of django)

Django static files uploaded to folder in Amazon S3 that can't be found
I'm trying to set up Django so that all static files are uploaded to s3, but for whatever reason, it's not working. Here is the relevant section in settings.py: AWS_STORAGE_BUCKET_NAME = "bucket_name" AWS_ACCESS_KEY_ID = os.environ.get("AWS_ACCESS_KEY_ID") AWS_SECRET_ACCESS_KEY = os.environ.get("AWS_SECRET_ACCESS_KEY") AWS_S3_FILE_OVERWRITE = False AWS_S3_REGION_NAME = "us-east-2" AWS_S3_CUSTOM_DOMAIN = ( f"{AWS_STORAGE_BUCKET_NAME}.s3.{AWS_S3_REGION_NAME}.amazonaws.com" ) AWS_S3_ENDPOINT_URL = f"https://{AWS_S3_CUSTOM_DOMAIN}" AWS_LOCATION = "static" STATIC_URL = f"{AWS_S3_ENDPOINT_URL}/{AWS_LOCATION}/" STATICFILES_STORAGE = "storages.backends.s3boto3.S3Boto3Storage" Supposing that my bucket is called bucket_name, this is what will happen: In my bucket_name bucket, there will be a folder called "bucket_name" with a static folder inside which contains all of my files. On the server, none of the assets will load. This is because they are looking for the url https://bucket_name.s3.us-east-2.amazonaws.com/static whereas it's written in https://bucket_name.s3.us-east-2.amazonaws.com/bucket_name/static. How do I either get the django assets to use this new address, or change the address on aws so that it aligns with django? I've done some things to debug this. It seems that if I redefine AWS_STORAGE_BUCKET_NAME after all of these lines, all that will change is the folder name will change from bucket_name to whatever else. Except I don't want to rename this folder, I want to either remove it entirely or get django to understand this folder. … -

Handle static and media files on django develop and production environment
I'm trying to understand how static and media files have to be handled on Django in Development and production environment.
