I have this model called "User." In the user model I have many
relations
hips such as:
has_many :creditcards
has_many :airlinememberships
and in my airlinemembership model I have
belongs_to :user
Now, what I would like to do is to delete not only the user but also the
airlinmembership info asssocciated with that user when a delete action
occurs. Now, I suppose I could do a find_by_id( user.id ) to go through
all the tables and destroy all assocciated info, but I''m thinkin that
there has to be an easier way in RoR. Plus, there are many many tables
that a user may have info in which make the code not ugly but certaintly
long.
Also, I know about the rails framework API: http://api.rubyonrails.org/,
but it seems like this site fails to really explain all the attributes
that can be used in a helper method, for example. I was wondering if
anyone knows of a better site that explains maybe a little better or
might provide some better examples? Thanks all,
~S

has_many :airlinememberships, :dependent => :destroy That should do the trick. Look it up for more info. --Tyler Prete On 7/16/07, Shandy Nantz <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> > > I have this model called "User."

I did the cascade on delete but the :dependent => :destroy is what I was looking for. Thanks you guys, either way it works perfectly. ~S -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
