Hello all,
Probably a typical beginner's question...:
Is there an elegant way to filter a query on the size of a collection
property?
Something like this:
...
mapper(User, user_t, properties = { 'tickets' : relation(Ticket) })
mapper(Ticket, ticket_t)
...
session.query(User).filter(User.tickets.size > 1)
...
I would find it ideal if the argument of filter() did not contain a
direct reference to the metadata.
Best regards
