Im currently new in rails and using v 2.3.11
I would like to ask if how can I query entries without including their
duplicates?
class CreatesStudent < ActiveRecord::Migration
def self.up
create_table :students do |t|
t.string :first_name
t.string :middle_name
t.string :last_name
t.timestamps
end
end
def self.down
drop_table :profiles
end
end
