Library section id for all

[worried-networking]

It's a quite controversial change, but for now I have no idea how to do this thing better. Basically librarySectionID field should be added automatically for any item if the field exists in metadata, and that's what I'm trying to achieve here.

Why Is this needed?

@Hellowlol there are photos in a library which not belong to any albums (and probably albums are not a thing anymore), and for those photos you can't get a librarySectionID in a nice&easy way. Without the field you can't create playlist with those photos, or send them to sync.

At least Photo.section() fails when the photo received from PhotoSection.all().

Problem occurs at least on with PMS v1.13.5.5332. Of course there is a huge chance that I'm doing anything wrong, but I really hope that it's not the case this time :)

Here is a short piece of code (from py.test) which fails with exception about unknown library:

deftest_playlist_photos(plex, photos):
items=photos.all()
assertplex.createPlaylist('Photos', items)

Im gonna put this on hold for a while, i want to see if we can do this another way. This touches parts of code that needs to be fast as its used pretty much everywhere. Who creates a playlist for images anyway? :P

Yep, I really hope we find a better way :) But anyway — when we receiving a MediaContainer IMO we should parse all of its attributes, not just processing internal items and abandoning all the meta. E.g. for library.section('Photos').all() I'm receiving following meta:

<MediaContainerallowSync="1"art="/:/resources/photo-fanart.jpg"identifier="com.plexapp.plugins.library"librarySectionID="4"librarySectionTitle="Photos"librarySectionUUID="2a550866-7060-4612-9f64-2b7b4e0a82b7"mediaTagPrefix="/system/bundle/media/flags/"mediaTagVersion="1534566129"nocache="1"size="10"thumb="/:/resources/photo.png"title1="Photos"title2="All Photos"viewGroup="photo"viewMode="131633">

And at least 3 attributes are pretty much useful for me: allowSync, librarySectionID and librarySectionUUID. Also librarySectionUUID would be helpful when creating new playlists. Looks like fetchItems should return a some kind of MediaContainer object, exactly as it is in the API.

Who creates a playlist for images anyway? :P

In latest version of Plex "playlist for images" used as albums :( And also you can't sent selection of photos without library ID to sync.

@Hellowlol I've made another try on this, this time it doesn't have this huge side-effect, please take a look on 5d9df1a.

[Hellowlol]

is this still needed?

[worried-networking]

Yep. Without this one you can't properly work (create playlists, set up mobile sync) with photos which stored outside of any albums.

Still dont like it but lets go for it.
