Rails - Jun 2006 - has_and_belongs_to_many

My web server has a list of users, and each of them has a collection of 
books. I want to save some certain number of books for each user, 
including the book''s name, author, and display the information for the 
user.

Which method should I use to store the subject information into each 
user subject?
Do I have to create arrays to store it?

Thanks for help!

if every different user has his own distinct books use " belongs_to " 
and "has_many " in the completing model. on the other hand, if every 
user has a certain amount of books, and some of the books are used for a 
different user, you should use "has_and_belongs_to_many" method.

(example would be like the following, if b are for books and user1/2/3 
for different users...)

=====this would be has and belongs to many===user 1 - - b1, b2, b3, b4
user 2 -- b1, b6, b8
user 3 -- b4, b5
etc

=====this would be belongs to ===
user 1 -- b1 , b2
user 2 -- b3, b4
user 3 -- b5, b6, b7
etc


...hope this helps.
good luck,

s
