Management commands

===================

|
Pruning library
|
|
---------------
|
|
|
|
Because Funkwhale is a multi-user and federated audio server, we don't delete any artist, album
|
|
and track objects in the database when you delete the corresponding files.
|
|
|
|
This is on purpose, because those objects may be referenced in user playlists, favorites,
|
|
listening history or on other instances, or other users could have upload files matching
|
|
linked to those entities in their own private libraries.
|
|
|
|
Therefore, Funkwhale has a really conservative approach and doesn't delete metadata when
|
|
audio files are deleted.
|
|
|
|
This behaviour can be problematic in some situations though, e.g. if you imported
|
|
a lot of wrongly tagged files, then deleted the files to reimport them later.
|
|
|
|
To help with that, we provide a management you can run on the server and that will effectively
|
|
prune you library from track, album and artist metadata that is not tied to any file:
|
|
|
|
.. code-block:: sh
|
|
|
|
# print help
|
|
python manage.py prune_library --help
|
|
|
|
# prune tracks with no uploads
|
|
python manage.py prune_library --tracks
|
|
|
|
# prune albums with no tracks
|
|
python manage.py prune_library --albums
|
|
|
|
# prune artists with no tracks/albums
|
|
python manage.py prune_library --artists
|
|
|
|
# prune everything (tracks, albums and artists)
|
|
python manage.py prune_library --tracks --albums --artists
|
|
|
|
The ``prune_library`` command will not delete anything by default, and only gives
|
|
you an estimate of how many database objects would be affected by the pruning.
|
|
|
|
Once you have reviewed the output and are comfortable with the changes, you should rerun
|
|
the command with the ``--no-dry-run`` flag to disable dry run mode and actually apply
|
|
the changes on the database.
|
|
|
|
.. warning::
|
|
|
|
Running this command with ``--no-dry-run`` is irreversible. Unless you have a backup,
|
|
there will be no way to retrieve the deleted data.
|
|
|
|
.. note::
|
|
|
|
The command will exclude tracks that are favorited, included in playlists or listening
|
|
history by default. If you want to include those in the pruning process as well,
|
|
add the corresponding ``--ignore-favorites``, ``--ignore-playlists`` and ``--ignore-listenings``
|
|
flags.
|
|
|
|
Remove obsolete files from database
|
|
-----------------------------------
|
|
|
|
When importing using the :ref:`in-place method <in-place-import>`, if you move or remove
|
|
in-place imported files on disk, Funkwhale will still have a reference to those files and won't
|
|
be able to serve them properly.
|
|
|
|
To help with that, whenever you remove or move files that were previously imported
|
|
with the ``--in-place`` flag, you can run the following command::
|
|
|
|
python manage.py check_inplace_files
|
|
|
|
This command will loop through all the database objects that reference
|
|
an in-place imported file, check that the file is accessible on disk,
|
|
or delete the database object if it's not.
|
|
|
|
Once you have reviewed the output and are comfortable with the changes, you should rerun
|
|
the command with the ``--no-dry-run`` flag to disable dry run mode and actually delete the
|
|
database objects.
|
|
|
|
.. warning::
|
|
|
|
Running this command with ``--no-dry-run`` is irreversible. Unless you have a backup,
|
|
there will be no way to retrieve the deleted data.
