Ruby on Rails Console Error

Question

I am try on to insert a value via the Rails console into the database, but it's not working.

the first command is
u=users.create(:name=>"bob",:address=>"Dublin")

this is the output after I running the first command

 u=Users.create(:name=>"Ben",:address=>"Dublin")
   (0.2ms)  BEGIN
  SQL (0.3ms)  INSERT INTO `users` (`address`, `created_at`, `email`, `name`, `password`, `updated_at`) VALUES ('Dublin', '2012-04-16 23:15:48', NULL, 'Ben', NULL, '2012-04-16 23:15:48')
   (9.1ms)  COMMIT
=> #<Users id: 2, name: "Ben", password: nil, email: nil, address: "Dublin", created_at: "2012-04-16 23:15:48", updated_at: "2012-04-16 23:15:48">

this is the second command
t=tweets.create(:status=>"I am a tweet from bob",:user=>u)

NameError: undefined local variable or method `tweets' for main:Object
    from (irb):4
    from /opt/bitnami/ruby/lib/ruby/gems/1.9.1/gems/railties-3.2.1/lib/rails/commands/console.rb:47:in `start'

tweets should be Tweet. Capital because its a class name, in ruby class names starts with Capital letter. If its relation then User.find(id).tweets.create(:status => "bla bla") but in this case you don't need :user => because he will know to who attach it. By Magic — Jakub Oboza

Assuming you have a Tweet model, you want

u = User.first
t = Tweet.create(:status => "I am a tweet from bob", :user => u)
