:dependent => :destroy vs ON DELETE CASCADE

rubyonrails-talk
#1

Sorry if I missed this in the docs somewhere.

My guess is that if I use :dependent => :destroy, then the application sends commands to the db to destroy the dependent records.

If I am using a database that supports FKs and ON DELETE CASCADE, then is there any point in using :dependent => :destroy ?

I think the point is in being able to keep that logic in the application itself, rather than having to go to two seperate code bases to find out what the result of an Object.destroy will be.

Just my $.02
