[Rails] Not getting all data fields from Rails query

Hello,

I am trying to get specific fields returned from my query but I am not
getting some of them.

For example when I use

User.joins(:books).select("users.email, users.fname,
books.name").find(7)

The generated SQL Query from above code is

SELECT users.email, users.fname, books.name
FROM users
INNER JOIN book_users ON users.id = book_users.user_id
INNER JOIN books ON books.id = book_users.book_id
WHERE users.id = 7
LIMIT 1

Output received is -

#<User email: "email1@email.com", fname: "Arlene">

Rails doesn't return the books.name even though the generated sql
query has that an if I run the sql directly I get the three columns.

I am on Rails 3.0.5 and Ruby 1.9.2p180. Is there any configuration
setting to enable this or am I missing something here?

Thanks,
-S
