Unable to list by various valid tags

[kingosticks]

Running the command:

list title

should list all track names but it errors with:

LocalBackend-3 ERROR 2020-04-17 23:06:06,116 Error getting distinct track: Invalid search field: track

And that's because we are incorrectly mapping MPD's 'title' tag to 'track' instead of 'track_name' but Mopidy-Local is rightly expecting 'track_name'.

Also the tags 'track' and 'file' (and 'filename') are not supported. For example, running the command:

list track

should list all the track numbers but it errors with:

ACK [2@0] {list} Unknown tag type: track

Those are just missing from the mapping structure.

Seems like you had already fixed the title tag?

I think for file and track (regarding the track number) we need changes in mopidy as well? Regarding this dictionary: https://github.com/mopidy/mopidy/blob/develop/mopidy/internal/validation.py#L34-L43.

One of those tagged issues is about the Mopidy changes. It's currently blocked on something I started and didn't finish. I'll try and take a look later.
