Hi all, I have a query that gets conditionally extending depending on
what's going with a given request. I've got a section where it should
join something and search on that join, but if the same join has already
happened, I get an error. I've figured out i can do the following, which
looks like I'm stepping out of the public api:
if UserOrgRoleAssoc not in [ent.class_ for ent in query._join_entities]:
query.join(UserOrgRoleAssoc)
Is there a better (proper?) way to do this?
A real API for this kind of thing is proposed long term:
https://bitbucket.org/zzzeek/sqlalchemy/issues/3225/query-heuristic-inspection-system
for now, not really, either look at the private attributes or track
these things on the outside (safer).
thanks!
Iain
