I only seem to get this error when I I try to eager load a child
collection -- eager loading one child item works fine.
I've tried:
lazy=False on the relation
as well as eagerload on the query:
query.options(eagerload('foo'))
but each time I get:
(OperationalError) (1054, "Unknown column 'None' in 'field list'")
Any ideas off the top your head?
PS. I can traverse lazily to the child collection, no problem.
Cheers,
--diana
