Clear tables with foreign keys + Propel

Question

I have a mysql database with some tables in it. An example of two tables:

TABLE "dogtoilets"
- type
- location_id (FK)

TABLE "locations"
- id
- latitude
- longitude

My question is how can I clear the table "dogtoilets and also clear the locations in my locations table that are linked to dogtoilets?

Tried this but locations don't delete ...

$dogtoilets = DogToiletQuery::create()
        ->leftJoinWith('Dogtoilet.Location')
        ->find();
    $dogtoilets->delete();

Answer 1

Hope this help: http://en.wikipedia.org/wiki/Foreign_key#CASCADE

Cascade will only work when you delete row in "locations", it automatically delete related rows in "dogtoilets"

In this case you should delete manually using your code.

Answer 2

Add this to the foreign key constraints :

ON DELETE CASCADE;

It will delete all referenced objects linked with a FK.
