find-by-sql

I'm using find_by_sql with Activerecord which I generate another field there that doesn't in the original table as a combination of different fields like:

select (field1 + field2) as new_field_name

If I try to access the newly generated field like:

@user.new_field_name

I get nothing! How do you suggest I should approach this problem
