Apparently there is an issue hen you are using linux (Ubuntu) and copy and paste your project to Windows. The Paths don't work. I had to change the settings in my STATICFILES_DIRS from os.path.join(BASE_DIR, 'myapp/static') to os.path.join(BASE_DIR, 'myapp', 'static')

I was helping this user on IRC, and they were getting confusing errors when running "collectstatic" or "findstatic" about the path not matching.

It turned out to be a conflict with joining Windows-style paths with Unix-style paths, as mentioned above.

I'm going to look at replacing uses of os.path.join and its ilk with pathlib, which does not suffer this problem.

I'm surprised this hasn't come up before. What does the error look like?

The documentation for STATICFILES_DIRS days, "these paths should use Unix-style forward slashes, even on Windows". I guess the problem is that the way BASE_DIR is generated on Windows using backslashes. It's not clear to me what Django can do about this but we'll see what Curtis comes up with.

Type: BugCleanup/optimization

The patch doesn't work because os.path.join(BASE_DIR, 'db.sqlite3') returns a string while BASE_DIR / 'db.sqlite3' returns a PosixPath. The documentation would have to use str(BASE_DIR / 'db.sqlite3') everywhere or Django would have to convert PosixPath to string.

Patch needs improvement: unset

I have resurrected the original patch with a fix for SQLite.

I'm not sure if various Django settings requiring a path (template DIRS, STATIC/MEDIA_ROOT, etc.) all support path inputs. Shouldn't we check and add tests for those before changing the project settings template?

Assigning Jon, since he's picked this up; marking as needs tests, since I think Claude is right, we have had regressions from moving to Path.
