Hi, I have 2 mappers:
mapper(Assembly, tables['assembly'], properties=dict( clusters=relation(classes['cluster'], cascade='all,delete,delete', passive_deletes=True, backref=backref('assembly')), contigs=relation(classes['contig'], viewonly=True, secondary=tables['cluster']))) mapper(Library, tables['library'], properties=dict( clones=relation(classes['clone'], cascade='all,delete,delete', passive_deletes=True, backref=backref('library')), reads=relation(classes['read'], viewonly=True, secondary=tables['clone']))) When I try to access assembly.contigs I get: (similar for library.reads) UnmappedColumnError: Column 'cluster.project' is not available, due to conflicting property 'project' 'project' is part of the (sharded) primary key. I got this error when upgrading to 0.5. Any hints to what is wrong here?
