Saving second order association with ActiveRecord

Rails
1

I was wondering if it was possible to save a given object that has
associations embedded within it.

For example if you have book = {:id=>4,:title=>“hi
there”,:pages=>[{:id=>4},{:id=>6}]}, then you could do some thing like

new=Book.new(book)
new.save

and then it would also do a join and save those books as well.

OR

can you do something like

book=Book.find(:first,:include=>“pages”)
book.pages[1].creator = “Joe Schmo”
book.save

Could you do something like that as well?

Yes =D

And if a book has_one :author, you can go @book = Book.find(1) and then
@book.author.new.
