Hi all,
I am relatively new to ruby and RoR. I created a simple rails proj named foo by giving command -> rails foo --database=sqlite3 It created a new rails proj.. So in that I created a simple db class named user by using the below command -> ruby script/generate model user so in db/migrate I got a file named 20090421211825_create_users.rb created. and in app/models : user.rb got created. in user.rb.. i have written like this
class User < ActiveRecord::Base validate_uniqueness :userid validate_presence_of :username end
in 20090421211825_create_users.rb, its like this
class CreateUsers < ActiveRecord::Migration def self.up create_table :users do |t| t.integer :userid t.string :username, :limit => 32 t.timestamps end end
def self.down drop_table :users end end
after I am done... I did rake db:migrate version=20090421211825
== CreateUsers: migrating
