You should rely on SQL, which is much more faster, I think.
@benches = Bench.find_by_sql(
"SELECT name FROM benches WHERE project_id = #{(a)project.id}
GROUP BY name ORDER BY name")
or:
@benches = Bench.find :all, :conditions => ["project_id = ?", @project.id]
:order => "name"
However, I didn't found how to put DISTINCT with find. Hurray for Rails !
