I have a model called MyContainer, which :has_many MyObjects. I want to delete all the MyObjects in the container without having to delete the MyContainer. My model does have :dependent => :destroy, however I don't want to have to delete and re-create the object because it is slower. Something like this does not work: @obj = MyContai...
