I'm working on creating a model that allows redirect to another
instance of the same type (Page). For obvious reasons, I don't want
it to be able to redirect to itself. How can I get the model to
properly filter this relationship? I'm currently getting the error:
Mysql2::Error: You have an error in your SQL syntax; check the manual

has_ancestry
belongs_to :footer,

:foreign_key => 'redirect_to_page_id',
:class_name => 'Page',
:conditions => 'id != #{self.id}'
