Mongoid / Mongodb and querying embedded documents

Question

I have Author and Book models.

An Author has many embedded Books.

Can I query the embedded Books

Answer 1

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.
