I think a better question is, "Why isn't there a :dependent => :deny option?"
It's very common to have a relational dependency where you want to deny the deletion of an object that has related objects. It would be really nice if this referential integrity rule was part of Rails core rather than having to write it yourself or use a plugin. It doesn't seem to me that it would be too difficult to add, if the count of the related objects is greater than zero deny the deletion. Example: Employee belongs_to :department Department has_many :employees, :dependent => :deny Deny deletion of a department if the department contains one or more employees. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
