delete statuses of destroyed user on treebook application

Cancel account on Rails App(treebook) is crashing the app, because I think when canceling the account, his statuses are still posted and they have no user_id. The first error is

ActionView::Template::Error (undefined method `gravatar_url' for nil:NilClass):

I am guessing that when a user cancels his account, his statuses should be removed from the statuses index page and that's what is causing the error.

Can anyone help with that?

Thanks! :)

You need to add :dependent => :destroy to the has_many :statuses

has_many :statuses, :dependent => :destroy

Then, when the user is deleted, so are their statuses. There are some other options, like nullifying and such. See: http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html#label-Deleting+from+associations

Thanks a lot :) I worked nice!

I also added :dependent => :destroy to :friends and :user_friendships so they can get deleted too.
