I have a user model that owns messages :
class User < ActiveRecord::Base
has_many :messages , :dependent => :nullify
end
I''m using nullify so that when the user is deleted, the messages
continue to exist - they''re just marked as being ownerless.
However, calling user.messages.clear actually deletes all his
messages, which I was a little surprised at. I would have expected
it to just set the user_id on all his messages to null, given I''m not
using :dependent => :destroy/:delete.
Is this intentional? Is there an equivalent call which will just
disassociate the messages? (Obviously I could use something like
user.messages.each {|m| m.update_attribute(user_id, nil)} - is there
anything actually built in?)
