Hello. I have my rb file:

class CreateDepartamentos < ActiveRecord::Migration
def self.up
create_table :departamentos, :id=>null do |t|
t.string :cvedept, :limit=>10, :null=>false
t.string :desdept, :limit=>20, :null=>false

  t.timestamps
end

end

def self.down
drop_table :departamentos
end
end

but when i try with a new record i get the next error:

Unown columno “departamento.id” in table “departamentos”.

but i dont have the field “id” in my table.

you need to tell rails what to use as your primary key (via the
set_primary_key function)
