HABTM

I'm looking for help with associations, specifically HABTM. What if
you have more than one HABTM for a model? The parser won't allow it.
So what to do? The manual doesn't seem to answer this question or
perhaps it does but I didn't see it.

This is my setup: If anybody can point our where I am mistaken I would
be so grateful....

I'm setting up a bookshelf application. My models are: Book, Author,
Publisher, Tag

In my scenario here is the logic:

- Book can have one or more Author
- Author can have one or more Book
- Book can have one Publisher
- Publisher can have one or more Book
- Book can have one or more Tag
- Tag can have one or more Book

In my model classes I have set the associations up as follows

class Book extends AppModel{
var $hasAndBelongsToMany = 'Author';
var $belongsTo = 'Publisher';
}

class Author extends AppModel{
var $hasAndBelongsToMany = 'Book';
}

class Publisher extends AppModel{
var $hasMany = 'Book';
}

class Tag extends AppModel{
var $hasAndBelongsToMany = 'Book';
}
