named_scope :status, lambda { |key|
{ :joins => :student_state, :conditions => ["student_state.key = ?",
key], :limit => 20 }
}
The above ended up working. However, I thought that the inner join I
specified would make the attributes of student_state available in the
xml output of the students controller (when going to the url
http://localhost:3000/students.xml). But it wasn't. Is this a limitation
of rail's xml capabilities?
