Mongoid / Mongodb and querying embedded documents

I have Author and Book models.

An Author has many embedded Books.

Can I query the embedded Books, or do I have to fetch Authors first to get Books?

You can query embedded documents, just qualify the name. Now, this will return all Authors that have books that match your query.

If Author is defined as having many :books (and book is an embedded::document)

@authors_with_sewid = Author.where("books.name" => "sewid").all

You'd then need to iterate over the authors and extract the books.
