Hi,
I've a problem to do a many to many relationship mapper declaration.
I will try to explain this with an example:
person_table(per_id, name, ...)
per_per_table(id, per_orig_id, per_dest_id)
per_orig_id = foreign key, reference to person_table.per_id
per_dest_id = foreign key, reference to person_table.per_id
How map this? I do...
mapper(Person, person_table, properties={'dest': relation(Person,
secondary=per_per_table)}
I want to do:
per = Person()
per_dest = Person()
per.dest.append(per_dest)
But, sqlalchmey can't determinate how do the relationship: "Error
determining primary and/or secondary join for relationship"
How can I solve this?
Thanks in advance.
M.
