When I try to access a specific mapped attribute the error below is thrown
but only if I use a custom __eq__().
def __eq__(self, other):
'''
'''
return self.aromatic_ring_id == other.aromatic_ring_id
When I print the type of both, the 'other' class is 'symbol': <class
'credoscript.models.aromaticring.AromaticRing'> <class
'sqlalchemy.util.langhelpers.symbol'>
Any ideas what went wrong?
