error of collectstatic for AttributeError: 'Path' object has no attribute 'startswith' #86

Question: Why I have to use root property of Path instance?

1. First try

# settings.py
STATIC_ROOT = root.path('collected_static/')
STATICFILES_DIRS = [
    root.path("web/static"),
    ("components", root.path("bower_components/")),
]

then, run collectstatic command print out:

Traceback (most recent call last):
  File "./manage.py", line 12, in <module>
    execute_from_command_line(sys.argv)
  File "/Users/raccoony/.pyenv/versions/3.5.0/envs/box/lib/python3.5/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line

    return module.Command()

    self._wrapped = get_storage_class(settings.STATICFILES_STORAGE)()
  File "/Users/raccoony/.pyenv/versions/3.5.0/envs/box/lib/python3.5/site-packages/django/contrib/staticfiles/storage.py", line 39, in __init__

    if not isabs(path):
  File "/Users/raccoony/.pyenv/versions/3.5.0/lib/python3.5/posixpath.py", line 64, in isabs
    return s.startswith(sep)
AttributeError: 'Path' object has no attribute 'startswith'

when I print out STATICFILES_DIRS

[<Path:/Users/raccoony/smartstudy/box/web/static>, ('components', <Path:/Users/raccoony/smartstudy/box/bower_components>)]

not path strings but Path instaces.

2. so I tried `root` property

# settings.py (modeified)
STATIC_ROOT = root.path('collected_static/').root
STATICFILES_DIRS = [
    root.path("web/static").root,
    ("components", root.path("bower_components/").root),
]

then, run collectstatic will be:

Traceback (most recent call last):
  File "./manage.py", line 12, in <module>
    execute_from_command_line(sys.argv)
  File "/Users/raccoony/.pyenv/versions/3.5.0/envs/box/lib/python3.5/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line

    self._wrapped = get_storage_class(settings.STATICFILES_STORAGE)()
  File "/Users/raccoony/.pyenv/versions/3.5.0/envs/box/lib/python3.5/site-packages/django/contrib/staticfiles/storage.py", line 37, in __init__
    check_settings(base_url)

    (settings.MEDIA_ROOT == settings.STATIC_ROOT)):
  File "/Users/raccoony/.pyenv/versions/3.5.0/envs/box/lib/python3.5/site-packages/environ/environ.py", line 670, in __eq__
    return self.__root__ == other.__root__
AttributeError: 'str' object has no attribute '__root__'

3. I used `root` property to `MEDIA_ROOT` too.

# settings.py (2nd modified)
STATIC_ROOT = root.path('collected_static/').root
STATICFILES_DIRS = [
    root.path("web/static").root,
    ("components", root.path("bower_components/").root),
]

MEDIA_ROOT = root.path("media").root

then, collectstatic runs without error.

The text was updated successfully, but these errors were encountered:

I solved this problem by str(root.path('path')) instead of root.path('path').root

daimon99 · 2016-09-07T15:09:09Z

I think you still use path the wrong way.
You should use like this:

STATIC_ROOT = root('collected_static')

but not

STATIC_ROOT = root.path('collected_static')

When you need a str object, you should use root('sub path'), when you wanta a Path object to chain it, you should use root.path('sub path')

raccoonyy · 2016-09-09T11:10:20Z

wow!

Thanks for your reply.

You are correct.

It turns out that environ, though a very good package, does a bit of a funny thing. Instead of relying on pathlib to do path stuff, it ships its own pathlib-alike. I'm guessing this is because it pre-dates pathlib, but regardless, and unfortunately, their built-in path library is a bit buggy. One type of bug is that it can't always compare strings with it's Path objects properly, throwing errors like those seen in: joke2k/django-environ#86 So, to fix this: Simply don't use the built-in pathlib-alike, and use the real pathlib library instead.

mlissner · 2022-04-14T22:26:20Z

I ran into this bug too. I haven't read all of environ's source code, but for us this happened because we had a setting configured using env.Path, and then we had it overridden in a django test via a decorator, like so:

@override_settings(
    MEDIA_ROOT=os.path.join(settings.INSTALL_ROOT, "cl/assets/media/test/")
)

Something about that combination made the built in env.path thing try to compare one of its Path objects with a str, which failed, as in the first comment.

The solution, which you can see here was to not use environ's path objects, and instead rely on pathlib.

I'm not super familiar with this package and why it has its own pathlib-alike (guessing it pre-dates py3?), but I think I'd suggest removing it since it appears to have bugs and (probably?) isn't necessary anymore. Instead, we could pretty easily, I think, migrate people to pathlib in their settings, though that'd be a backwards incompatible change.

This is on my plans, but right now I don't have enough time for that. I'll try to return to this topic a bit later

1. First try

2. so I tried root property

3. I used root property to MEDIA_ROOT too.
