Hi all, I have a user has many numbers relationship. When I query User.find(:all, :include => :numbers) I get all the users with their numbers. I''m looking for a method that removes the number from a user eg users[0].numbers[1].delete . I basically want ot remove the association but I''m unable to find such a method.

collection.delete(object, ) - removes one or more objects from the collection by setting their foreign keys to NULL. This will also destroy the objects if theyre declared as belongs_to and dependent on this model. so in your case: users[0].numbers.delete(users[0].numbers[0]) users[0].numbers.delete_all # would kill everything use has_mane :numbers, :dependent => destroy if you want it to destroy the records in the db, too -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

So you just want to unassociate that number from a user?
number = Number.find(params[:id])
number.update_attribute("user_id",nil)
