Rails 3.2.3

My need is populating a database using an easiest way.
So I created a model

rails g model MyModelName title:string, another_title:string, description:text

Now I’m trying to populate a database some data using irb

mm = MyModelName.create :title =>'title1', :another_title=>'fdfds', :description =>'desc1 fdsfds'

But here is an error

NameError: uninitialized constant MyModelName
    from (irb):4
    from /home/alex/.rvm/rubies/ruby-1.9.3-p194/bin/irb:16:in `<main>'

How do I solve it?

Have you run rake db:migrate yet?

Are you using rails console?
