deletes entries in these tables?
Tagtable.photo_id_list contains a list of images associated with that
tag. For photos they look like this: thumb0000000000000cc1 – i.e.
"thumb" + the hex representation of the photo id. Or in printf-terms:
("thumb%016x", phototable.id).
For videos it is the same (IIRC), though with "video-" instead of
"thumb" and from the videotable.id.
For example, the tag table. Given the photo id, I know the thumbnail
name. The problem is to find that name (eg thumb00000007f) in the tag
table's photo_id_list. Also, I need to find the photoid in the list as
well, to delete the Folders entry.
Any help on deleting entries from the various shotwell tables, given a photo
id, would be appreciated
Thanks
Other things... just noting from looking at the database:
- There is a link phototable.id <=> eventtable.primary_source_id as
well. I guess it either sets the date of the event and/or thumbnail.
- Reference from backingphototable: backingphototable.id <=>
phototable.editable_id.
There is a tombstonetable which I cannot quite figure out does or how it
is referenced....
The saved search table I have not looked at so much... but also seems
simple, though not needed for your application, I guess.
Hope that helps.
