Question

I have a Book < LibraryItem

and a Book::Page, which is defined as

class Book
  class Page

in models/book/page.rb

LibraryItem has a method called can_edit?

But my Book::Page.new.can_edit? returns no method error…

how do I include the instance methods from LibraryItem in my namespace?

Answer 1

This returns an error because Page does not have a can_edit? method. A Book has a Page class, but Page is not a subclass of Library item (only Book is). So can_edit? is valid for Book but not for Page.

Try

p Book::Page.superclass

And you will get Object
