Hello, Any idea why the following doesn't work ? :
Topic2= orm.aliased(Topic)
q= Occurrence.query.\
join(Occurrence.datasheet).\
options(orm.contains_eager(Occurrence.datasheet)).\
join(Topic2).\
options(orm.contains_eager(DataSheet.topic,alias=Topic2)).\
outerjoin(Occurrence.species).\
options(orm.contains_eager(Occurrence.species))
I get a:
ArgumentError: Can't find property 'topic' on any entity specified in this
Query. Note the full path from root (Mapper|Occurrence|occurrences) to target
entity must be specified.
and I don't understand why ..
Thanks,
Julien
