[Subsonic] getArtistInfo doesn't work with song id

[wiz78]

Subsonic API docs specify that getArtistInfo can be called with "The artist, album or song ID.", but the Music app only handles the first two cases.

Please let me now!
Thanks

Actually, we don't currently handle the case of album IDs, either. I hadn't noticed that the API spec defines the argument like that, as the other similar method getArtistInfo2 is defined to support only artists IDs. Anyway, this shall be fixed for the next release.

Do you know any Subsonic client which would try to use getArtistInfo by supplying the ID of an album or a track?

My own Soundwaves (https://apps.apple.com/app/soundwaves/id736139596) uses getArtistInfo with track ID, to show some details about the currently playing track, if the user requests them. It can't pass the artist ID since Subsonic doesn't provide it for tracks.

If you need a promo code to test it, just let me know and I'll email it to you.

For example:

Would your promo code solve this issue?

Okay, thanks for the info. I don't have any Apple devices to test with so that explains why I haven't seen any problem.

It can't pass the artist ID since Subsonic doesn't provide it for tracks.

Are you sure about that? At least the Subsonic demo server seems to include the property artistId on the child entries as can be seen e.g. in http://demo.subsonic.org/rest/getMusicDirectory.view?u=guest4&c=test&v=1.16&s=123&t=fcf41657f02f88137a1bcf068a32c0a3&f=xml&id=260

It should be noted, though, that this artistId cannot be passed to getArtistInfo, it works only with getArtistInfo2. According to http://www.subsonic.org/pages/inc/api/schema/subsonic-rest-api-1.16.1.xsd, this property has been added by the API v1.8.0 while getArtistInfo and getArtistInfo2 are not available before API v1.11.0.

It should be noted, though, that this artistId cannot be passed to getArtistInfo, it works only with getArtistInfo2.

that bit was not quite clear to me from the docs. However getArtistInfo2 would require a different way to browse similar artists too, since the ids it returns cannot be passed back to getMusicDirectory, like those returned by getArtistInfo. I don't browse by ID3 tags anywhere else in the app (there are pros and cons in both kind of navigation, but using getMusicDirectory seems to be the most useful way so far)

[paulijar]

Okay, I see. The Subsonic API can be a bit awkward to use with its ID3/filetree duality. And the Music app's implementation of the API is yet another story because of the different starting point and somewhat different design philosophy.

But anyways, I have now made a fix for this. So when the next Music app release rolls out probably withing a couple of weeks, the getArtistInfo should work fine also with track and album IDs.

Thanks for reporting the issue!

Music v1.4.1 is now out, including also this fix/enhancement.

[erwinlagu]

is this already fixed?

@erwinlagu Yes, as stated above: #906 (comment)
