I'll continue my investigations and come back when I'll found the cause(s).

Hi,
There's nothing that could cause the problem you describe in the example
you provide maybe the guilty lines where not included.
The easier way to go should be to step by step reproduce your model
structure until you face the problem you describe and then post an
example code :
Hi,
When SQALchemy can't guess the join condition to use for a relationship,
you have to use the primaryjoin parameter :
ursmst = relationship('Usrmst',
primaryjoin="Workgrp.workgrp_owner==Usrmst.id")
Hope this helps.

what result do you get with :
