Ok, that's what I thought.. thanks!
I have a typical joined table inheritance, with Content being the "base"
class, and childs as Document, Folder, Event, etc.
I have added a transparent translation package with the "one translation
table per entity" approach (also using joined table inheritance),
and hybrid properties.
So I have ContentTranslation being the "base" class, and childs like
DocumentTranslation, FolderTranslation, EventTranslation, etc. which
contain translation fields specific to each class.
You helped me some weeks ago on this and I ended with (1), in which two
relationships were added to every children of Content
("current_translation" and "translations"), and hybrid properties
pointing to their dedicated translation class.
It works well, the only minor issue is that I don't have any
relationship on the base Content class (as you told me in the past that
overriding relationships could be problematic).
I made some modifications (2) in which the relationships are now
prefixed with the class name, and added two properties which point to
the class relationship, so that in the end:
- Content has a "content_current_translation" and
"content_translations" relationships, and two property
"current_translation" and "translations" pointing to them
- Document has a "document_current_translation" and
"document_translations" with also two property current_translation and
translations pointing to them, but the minor issue is that the
content_current_translation is also joined loaded, which I'd like to
avoid.. and I'm wondering what would be the best approach.
I don't know if it's clear, but if it is not I could make a test case
