Examples of the new LOAD and SAVE functions?

<< < (4/7) > >>

mark_h:
Another example.  In a view with one album showing, this expression:

if(isequal([track #],load(vartracks[artist][album]),5),save([track #],vartracks[artist][album],),-1)

will count the number of tracks on the album and deposit the result in the variable: vartracks[artist][album]

I'm guessing this could be written to a field for all albums, but would generate a lot of variables...?

Update:

OK, so add a user field 'Album Tracks #' as a calculated field:

if(isequal([track #],load(vartracks[artist][album]),5),save([track #],vartracks[artist][album],1),load(vartracks[artist][album]))

And now you have the count of track numbers for all your albums available...

The (terrifying?!) power of variables... :D

mark_h:
Next challenge - calculate an album average rating...

vagskal:
Clever mark_h!

This gave me the idea to create a field relational to another field (other than the already available artist, album and series stock fields). But this did not work:

Field A (for internal use)
Save([Original Artist],varOriginalArtist[Name],1)

Field B (for display making in effect [Original Artist] relational to [Name]
Load(varOriginalArtist[Name])

I might have misunderstood something...

EDIT because I got wiser: This seems to actually work:

Field A (for internal use)
if(IsEmpty([Original Artist]),,Save([Original Artist],varOriginalArtist[Name],1))

Field B (for display making in effect [Original Artist] relational to [Name]
Load(varOriginalArtist[Name])

I meant determine the random week mathematically and Save() the result.

Well it seems to work only when both [Field A] and [Field B] are set as columns in a view. It does not work if only [Field B] is set as a column. Is that the intended behaviour?
