contain STATICFILES_STORAGE.

There is no STATICFILES_STORAGE constant in my settings module. I took a
look at the bytecode in pycache. There was no reference to
STATICFILES_STORAGE there, either, but I did see a reference to
STATICFILES_DIRS. I deleted all __pycache__ files and their folders, but
the same identical error persisted.
I looked at the source code that was generating the error:
python3.11/site-packages/django/conf/__init__.py
specifically, line 278, which happens to be inside the definition of a
class Settings.
if self.is_overridden("STATICFILES_STORAGE"):
if self.is_overridden("STORAGES"):
raise ImproperlyConfigured(
"STATICFILES_STORAGE/STORAGES are mutually exclusive."
)
The assumption seems to be that if both are overridden the dev is using
both of them, and hence the error. Because I use white noise, it makes
sense that STORAGES has been overridden. But since I have no reference to
STATICFILES_STORAGE anywhere, it follows that the default value of
global_settings is being inherited in my local settings, thus generating
the error.
django/django/conf/global_settings.py, line 630:
STATICFILES_STORAGE =
"django.contrib.staticfiles.storage.StaticFilesStorage"
The problem here is that on line 274 of the same file, we have:
STORAGES = {
"default": {
"BACKEND": "django.core.files.storage.FileSystemStorage",
},
"staticfiles": {
"BACKEND":
"django.contrib.staticfiles.storage.StaticFilesStorage",
},
}
Are these constants mutually exclusive for everything ''but''
global_settings? I commented the entire block:
# if self.is_overridden("STATICFILES_STORAGE"):
# if self.is_overridden("STORAGES"):
# raise ImproperlyConfigured(
# "STATICFILES_STORAGE/STORAGES are mutually
exclusive."
# )
# warnings.warn(STATICFILES_STORAGE_DEPRECATED_MSG,
RemovedInDjango51Warning)
And that worked:
