How can I get this many-to-many self-join to show related records?

Featured Replies

I know I've done this before, but can't find an example of the functionality in my archives and can't seem to work out how to do it again.

I've got two tables: PERSONS and CONNECTIONS. PERSONS has an `id` field and CONNECTIONS has `person_1_id` and `person_2_id`. There's a relationship from PERSONS to CONNECTIONS with `id` = `person_1_id` and from CONNECTIONS to another TO  into PERSONS, connections_PERSONS, with `person_2_id` = `id`, but these relationships may need to change to make this work.

On a layout with a context of PERSONS, I need a portal into CONNECTIONS that shows the names of the person on the other side of the relationship. So if Bill and Ted are connected, when viewing Bill's record I see Ted in the portal and when viewing Ted's record I see Bil's record.
