added to it without necessarily having
the relational objects for the entity table around. Its
relationship with the Entity object is simply to ask what the
upstream and downstream dependencies are. Maybe the association
object pattern is the way to go with it.

Hi all,
I'm having some trouble with using a schema with a many-to-many
declarative mapping. The error i'm getting is as follows:
sqlalchemy.exc.InvalidRequestError: One or more mappers failed to
compile. Exception was probably suppressed within a hasattr() call.
Message was: One or more
the declarative
method? Would it be normal to create the mapping for that table after
it has been created in order to get a relational object?
Thanks again,
nigel
