Title: Condition relative to album, not to track, how ?
Post by: Cmely on December 24, 2016, 10:17:53 am

Hello,

I've been looking for a solution but found nothing to help me, so I ask the forum.

I would like to make some filters / conditions that test some field values and apply the result to the whole album  :o
With some example it will be easier to understand, I guess (I have to admit that I have myself some difficulties to understand my previous sentence  :D :D).

For instance, I would like to be able to set a view / filter with this kind of condition :

- If at least one track of the album have been played don't show the whole album (in order to create a real 'never played' view)
OR
- If at least one track of the album is rated 5 stars then show the whole album.

For the first test I was thinking to calculate the sum of the "Played Number' field, but couldn't find how.
If you have any clue, I'll be very grateful  :D

The "album" isn't a thing in MC.  But...I think it could be at least somewhat done with variables.  Variables aren't super simple, I'll think about it though

Yeah, variables are the answer.

Although the second is as simple as:

[Rating]=5 ~a

My smartlist for how many times an album has been played: (create your own smartlist with these rules: it will be used below)

[Media Type]=[Audio] [=save(100000,v_albumplayed[album artist (auto)][album])1]=1 [=if(compare([number plays],<,load(v_albumplayed[album artist (auto)][album])),save([number plays],v_albumplayed[album artist (auto)][album]),1)1]=1

Once run, the number of plays for a given album will be stored in the variable: v_albumplayed[album artist (auto)][album] and you can create the filter, eg

[=compare(load(v_albumplayed[album artist (auto)][album]),=,0)]=1

This will result in only showing albums that have never been played.

Then you can OR the two rules above in the finale smartlist:

playlistid==* ([=compare(load(v_albumplayed[album artist (auto)][album]),=,0)]=1 or [Rating]=5) ~a

*your smartlist containing the rules above that calculate the number of plays.

[edit: fixed some errors transcribing from my setup to this example!]

Although, now I've reread your original request, I see you might be asking for something slightly different, eg

If an album has a track rated 5, show the whole album
Otherwise
Show all unplayed album tracks

All you need for that is two smartlists; one for each condition.  And then a smartlist that calls both to combine the results.

eg,

smartlist 1: [Rating]=5 ~a
smartlist 2: [Number Plays]=0

smartlist 3: playlists IS ANY smartlist1, smartlist 2

Ferday, Mark_h, thank you for helping.

Mark_h thank you for giving me more than a hint  :)

Your first answer was the best (for me). The two conditions didn't need to be tied together. However, both of your answers were very helping. Thanks !  :D

Mark_h, I've been trying to adapt your answer in order to create a View showing albums based on the number of times albums has been played...but I did certainly miss something and haven't been able to achieve this.

Would you be kind enough to point me in the right direction ? (I mean, I know this is already what you've done  :D but I'm afraid I'm not savvy enough ...).

I made some transcription errors copying the rules from my library to the example.  I've fixed those now...  Perhaps it now works better for you?

 ?

When I create a smartlist with your expression :

[Media Type]=[Audio] [=save(100000,v_albumplayed[album artist (auto)][album])1]=1 [=if(compare([number plays],<,load(v_albumplayed[album artist (auto)][album])),save([number plays],v_albumplayed[album artist (auto)][album]),1)1]=1

I get an empty smartlist. Is this normal ? (I've created it by using 'Import/export' in smartlist rules)

I copy and pasted that and get my entire collection presented.  This is what I'd expect, as the smartlist is looking at every entry to generate the 'album played' variable.

If I add an expression column to the result view with

load(v_albumplayed[album artist (auto)][album])

I see the album played count displayed...
