Rails - May 2008 - Select dropdown based off join table's include?

I have a "New Photo" view where I''d like to provide a select
dropdown
of the user''s favorite locations.  Getting the data for a
user''s
favorites is no problem, but I''m not sure how to put the location name
into the select form.

def new
  @photo = Photo.new
  @favorites = current_user.favorites.find(:all, :include
=> :location)
end

<%= f.collection_select :location_id,
@favorites, :location_id, :location_id, { :include_blank => true }, {}
%>

(the 4th parameter in the f.collection_select above is my problem)

On a related note, is there a more efficient way to query for the
locations'' id & name w/o returning all fields?  Or is it not really
that much of a performance issue?

Any tips would be greatly appreciated.  Thanks in advance.

Add location_name as a method on User:

  def location_name
    self.location.name
  end

Then you can pass :location_name to collection_select.

Ciao,
