Hello, I wondered if it is possible to use a class mapped against multiple tables as a relationship() in another class?
something like:
### Content
content_translation_join = sql.join(
t_content, t_content_translation
)
orm.mapper(
ContentTranslation, content_translation_join,
polymorphic_on=t_content.c.content_type_id
)
orm.mapper(
Content, t_content,
polymorphic_on=t_content.c.content_type_id,
properties={
'translations': orm.relationship(
ContentTranslation,
# more stuff here
)
}
)
### Document
orm.mapper(
DocumentTranslation, t_document_translation,
inherits=ContentTranslation,
polymorphic_identity=some_id
)
orm.mapper(
Document, t_document,
inherits=Content,
polymorphic_identity=some_id
)
I tried (1) but it doesn't seems to work so I want to be sure that it's
not possible :)
Thanks!
Julien
