class CreateUsuarios < ActiveRecord::Migration
def self.up
create_table :usuarios do |t|
t.string :nome
*t.string :login, :limit => 20*
e.g *t.integer :age , :limit => 2 //Here you set the age to be a
short.ie.it now occupies only 2 byte rather than actual 4 bytes of integer*
t.timestamps
end
end
This way you can set limits on the size of your columns. Regarding your
second question, I am still unable to get what you want to do.
