I'm trying to get DM to include fields from a related model's relationship join table, but I can't get DM to include the join fields using $a->* methods.
The A to B relationship is 1-m, in that A::has_one('b') and B::has_many('A'). Also, based on other factors A may not have a related B.
For now I've worked around it with a raw query using $this->db->query(), because DM strips off the join field in _process_query():
Code:
SELECT
`A`.*,
`A_B`.`b_id` AS b_id,
`A_B`.`status` AS b_status
FROM
(`A`)
LEFT JOIN
`A_B` A_B ON `A`.`id` = `A_B`.`A_id`
WHERE
`A`.`foo_id` = ?
AND
[ nested clause groups filtering on other fields in A ]
I can get B.id using include_related(), but that's only half the issue. I can't get A_B.status no matter what I do; the where clauses seem to erase include_join_fields() somehow.
I thought maybe include_related() could get the join fields, but no luck so far. Also, no variations of $b->a->* methods that set up the same query seem to work. This is also complicated by the fact that there are status fields in A, B, and A_B, but I can easily rename A_B.status.
