Alternative to PipelineCachedStorage in Django-3.1?

[ngkabra]

PipelineCachedStorage is not supported for Django-3.1+. The documentation has no mention of this (although the release notes do).

What is the suggested alternative in case someone wants to recreate the same behavior? Does PipelineManifestStorage do pretty much the same thing? What are the differences between the two?

(I'm a little confused because the documentation mentions PipelineManifestStorage in some places and PipelineCachedStorage in other places without any indication of the relation between the two, if any)

Hi @ngkabra,

The documentation could be outdate, the best thing is to directly show the code of the storage.py

As you can see PipelineStorage an inherit of StaticFilesStorage and PipelineManifestStorage is an inherit of ManifestStaticFilesStorage (how is a subclass of StaticFilesStorage).
The only thing that brings ManifestStaticFilesStorage compared to StaticFilesStorage is to replace the paths of your files with their hashed counterparts and update the cache appropriately.

Concerning PipelineCachedStorage, it's a subclass of CachedStaticFilesStorage how isn't any more available in Django 3.1.0

Hope this helps you.

Did you find a solution for that? I updated from Django 3.0 to Django 3.1 and get this error:

AttributeError: module 'pipeline.storage' has no attribute 'PipelineCachedStorage'

Did you read my previous answer?

So you can't use PipelineCachedStorage anymore due to Django backend remove the feature. Try to replace it with ManifestStaticFilesStorage class who is more recent.

Note: file docs/usage.rst should be updated at line 91.

@TheBuky Thank you for the fast response.

I replaced it with ManifestStaticFilesStorage but getting this error now:

ValueError: The file 'admin/css/widgets.2753875e2781.d1e228221a7f.css' could not be found with <pipeline.storage.PipelineManifestStorage object at 0x7f7dfdeb1c88>

Any idea what to do now?
