users = User.all
user_hash_array = users.collect{|user| {:value => user.id, :label => user.firstname}}

This will work like following

id   firstname   lastname
1    Salil       Gaikwad
2    Nidhin      Bose

This will gives you following

user_hash_array = [{:value=>1, :label=>"Salil"}, {:value=>2, :label=>"Nidhin"}]
