django-pipeline 不适用于 S3Boto3Storage

Question

How can I use S3Boto3Storage with django-pipeline?

According to the docs it looks like it would work: https://django-pipeline.readthedocs.io/en/latest/storages.html#using-with-other-storages

The documentation looks a little bit outdated, because the package name and class name changed over the past years.

This is how my storage class looks like with the correct package and class name.

from django.contrib.staticfiles.storage import ManifestFilesMixin
from pipeline.storage import PipelineMixin
from storages.backends.s3boto3 import S3Boto3Storage

class S3PipelineManifestStorage(PipelineMixin, ManifestFilesMixin, S3Boto3Storage):
    pass

In my settings.py I set the Storage class to the above created one.

STATICFILES_STORAGE = 'myproject.storages.S3PipelineManifestStorage'

running collectstatic is returning this two errors

python3 manage.py collectstatic
This will overwrite existing files!
Are you sure you want to do this?

Type 'yes' to continue, or 'no' to cancel: yes

1. Any idea what is wrong?
2. Was someone able to use this combination succefully or is this feature broken in 2022?

Answer 1

With the current master branch it works perfectly.

pip3 install git+https://github.com/jazzband/django-pipeline.git@c85a2572e53218716359126d9465cc63447817e5

There is a bug in the current 2.0.8 version. So wait for the next release.
