this is my code
Post.select(:id, :user_id, :title).limit(30).includes(:user)

resuls in this sql

Post Load (9.0ms)  SELECT "posts".id, "posts".user_id, "posts".title FROM "posts" LIMIT 30
User Load (720.6ms)  SELECT "users".* FROM "users" WHERE ("users"."id" IN (5,6,4,1,8,56,83,24,68,2,45,21))

but querying for "users".* is taking too long
is there a way I can select less fields in the includes too?
