destroy! fails (has :n, :through => resource)
Reported by Leon Bogaert | September 8th, 2008 @ 03:47 PM
I've created two models with an many-to-many association between them. Using destroy! on a collection fails with a sql-query.
The ruby code can be found here: http://pastie.org/268371
The error is: table images has no column named car_id (Sqlite3Error) The @text attribute from command contains: DELETE FROM "images" WHERE "cars_images"."car_id" IS ? AND "images"."id" IN ?

I've also tried it with mysql and that gave the same error.

- Tag set to “dataobjects, dm-core, has_and_belongs_to_many”
Also a test bases on the example from this page: http://datamapper.org/docs/assoc...

OK. I checked the specs and noticed that a lot of the manyToMany stuff isn't implemented yet. Is anyone busy developing this?

Leon, we are hard at work fixing the current associations code in dkubb/dm-core. There's still alot more work to do since we're basically rewriting alot of DataMapper while writing better specs and docs for it, but we should have it totally resolved in the next month or two.
I will assign this to myself since I'll need to verify the behavior before merging dkubb/dm-core back into the mainline.

I can confirm this is resolved with dm-core/next. Attached is a script to demonstrate the fix.
