I''am newbie in RoR, so my question might look stupid, but I stuck in
one
thing.
I''ve created 3 tables:
users{
id,
user
}
books
{
id,
book
}
books_users{
book_id,
user_id}
Model
class Book< ActiveRecord::Base
has_and_belongs_to_many:users
I can''t figure out how to insert data to the books_users table.
For example users post info about new book and information should be
stored in the tables books and books_users.
>>@book = Book.new(params[:book])
>>@book.user_ids = @session[''user''].id
>>if @book.save
But I get the error message undefined method `each'' for
#<User:0x4cef104>
I know that it is because of the line "@book.user_ids
@session[''user''].id", but I can''t userstand how
to writte it corectly.
I''ve red a couple of tutorials but haven''t found a solution.

Thank you, Peter I got it working by changing the line @book.user_ids = @session[''user''].id to @book.users << User.find(session[''user''].id) Your code should also work. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
