Re: Notice (8): Undefined index: abc [APP\views\......\index.ctp

If it's a one to many relationship (author has many books, each book
has one author):

In Book Model you stick this:
var $belongsTo = array ('Author');

In Author Model:
var $hasMany = array ('Book');

I'd recommend going through these tutorials:
