Question

I want to be able to take the id from another collection, and use that as the key for a hash. Then I would like to be able to apply various attributes to each. It would be something like:

@books = Hash.new

@books[key].title = "A Title"
@books[key].condition = "Poor"
@books[key].rating = "Excellent"

or something to that effect. Is this even possible with some tweaks?

Thanks for your time!

Edit: I should have added that it is undesirable to create a Class in this case, although I may end up having to do that.

Answer 1

You can use multidimensional Hash?

@books = Book.all
@books_hash = {}
@books.each do |book|
  @books_hash[book.id] = {}
  @books_hash[book.id][:title] = book.title
  @books_hash[book.id][:rating] = book.rating
end
