I'm developing a module, and there is a table that needs views integration. The table is not so special, but can't find a solution yet.
This is how my table looks: nid_a|nid_b|data
I would like to join this table to the node base table, with nid_a as joining key, and nid_b should come from a contextual filter (aka argument).
How can I achieve this?
System: Drupal 7.x and Views 3.x
