Proteins_seed has a "putative" relation that joins to Proteins_putative via relation(Protein_putative, secondary=homologues), Proteins_putative has a relation() to Interaction, which then has a further relation() to Proteins_putative again, etc. Every table in your picture gets a mapped class except for homologues, every line gets a relation() except for the lines in and out of homologues which is encompassed by a single relation(). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
