Defined in:
app/models/page.rb

Overview

requires

* path ( unique, > 1 char and starts with a / ) * menu ( unique and > 3 chars ) * title ( > 3 chars ) * body ( > 3 chars )

named_scope(s)

* not_home (returns those pages where path is not just ‘/’) * roots

uses acts_as_list for parent / child relationship. As this is only a parent and child and no deeper, its ok. If it were to get any deeper, the list should probably be changed to something like a nested set.

named_scopes ALWAYS return an “Array” so if ONLY want one, MUST use a method. by_path returns the one(max) page that matches the given path.
