Scripts¶

We have a bunch of python scripts to execute common tasks.

Note

During development, you can use ./develop.sh manage ... to execute the commands. In production, the command should be run inside the appropriate container using python manage.py ....

metadata for canonical recordings
canonical recording redirect
canonical release redirect

These tables are created by the mapping canonical-data management command. If canonical-data is called with –use-lb-conn then the canonical metadata and recording redirect tables will

be in the listenbrainz timescale database connection

If called with –use-mb-conn then all tables will be in the musicbrainz database connection. The canonical release redirect table will always be in the musicbrainz database connection.

./develop.sh manage dump create_mbcanonical [OPTIONS]
