#156 Pubs with multiple artists get multiple, separate COVERARTs

[MartyD]

Creating a new publication with multiple artists, or editing an existing publication to add another artist, creates separate COVERART title records for each artist. This is in contrast to adding multiple authors on the pub or on a content entry, where authors are then all assigned to the same title record. It is also in contrast to the Edit Title interface, where adding authors to a COVERART title assigns those authors to that title instead of creating new records.

I was mistaken about the behavior of pub deletion. It is aware of shared COVERART titles and behaves correctly.

Editing the pub's artist has been fixed in mod/pa_update 1.6, checked in 31-Jan-2010 to behave as follows:

- A single-artist, unshared COVERART is deleted (unchanged)
- A single-artist, shared COVERART is only dissociated from the pub (NEW)
- A multi-artist, unshared COVERART has the artist removed (unchanged)
- A multi-artist, shared COVERART is dissociated from the pub, and a new copy of the COVERART is added back, minus the artist being removed (NEW)

Sorry, ignore the previous comment. I updated the wrong bug.

In general, a pub should not contain multiple coverart titles unless it actually has multiple covers. This case is extremely rare but might apply to tête-bêche and dos-à-dos bound pubs that actually have two covers (and thus separate cover art possibly by different artists).

Having a cover art that should be credited to multiple contributors seems to also be somewhat rare but should be supported separately.

Currently, there seems to be code that handles the display of multiple cover art title records in a fashion similar to cover art records with multiple "authors".
