Hello, I'd like to build something like a family tree where "descendants", "mother" and "father" are properties (of each "person-object") defined by a mapper. When these properties are accessed, one (in case of "mother" or "father") new "person-object" schould be loaded, or a list of "person-objects" (in case of "descendants"). Each row in the table presents one persons, who "knows" its "mother_id" and its "father_id".
That is not really a normal tree structure because a "person-object" may not only have many "descendants" but also has more than one ancester ("mother" and "father"). Is there a way to build a mapper that can map these relationships? thanks for help, jawa --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
