We introduce a new node_type, storage, which can support different file
storage backends and makes them available for browsing via dedicated
entry points in the application. We intend to keep pillar storage
agnostic and support both internal/local storages as well as
remote/hosted solutions.
Introducing the asset of type file creation. This involves making a
node collection entry of type asset, as well as a file collection
entry, plus all the needed variations if such file is an image or a
video. Further, depending on the storage backend (pillar or other) we
synchronise the files there using rsync. Currently this functionality
is available only via pillar-web, since a web interface is needed to
upload the file in a storage folder, which is shared between the two
applications.
We updated the way files are stored in the files collection. Any
derived variation of a file (different encoding or size) is stored as
new record, referencing the original as a parent.
We also added a generate_link method, which is in charge of providing
the client API with the actual link to the backend specified by the
file.
