How recording-mbid-lookup endpoint works

I’m still experimenting with troi

I’m testing the playlist_from_mbids patch. I understood the associated enpoint return one mbid for each mbid send ? How is this relation made ?

I supposed the response is in :

github.com

metabrainz/listenbrainz-server/blob/e7c40c42ad664baed62e7b0ca37f57e00892da1f/listenbrainz/labs_api/labs/api/recording_from_recording_mbid.py

import psycopg2
import psycopg2.extras
from datasethoster import Query
from flask import current_app

from listenbrainz import config

psycopg2.extras.register_uuid()


class RecordingFromRecordingMBIDQuery(Query):
    '''
        Look up a musicbrainz data for a list of recordings, based on MBID.
    '''

    def names(self):
        return ("recording-mbid-lookup", "MusicBrainz Recording by MBID Lookup")

    def inputs(self):
        return ['[recording_mbid]']

This file has been truncated. show original

but I dont speak sql :s

It looks like this is intented to create a playlist based on a list of mbids but not from only one mbid. Is that correct ?

The endpoint will 1 mbid for each mbid sent and some metadata like artist name, recording name etc.

The mbid returned will be different from the one sent in case of redirects. Say there were 2 recordings in MB but at some point it was discovered that one is a duplicate of the second so both were merged into one. So the mbid which was merged will then have a redirect to the other. In all other cases, the same mbid will returned back.

You can create a list of just 1 mbid and it will create a playlist of 1 mbid in that case :).

I didn’t understood this patch wasn’t making any recommendation. It only create a playlist from a list of mbid. Okey thanks sorry ^^’
