Hi, I am a newbie.

I am wondering if anyone can show me how to define a primary_key at migrate

create table (:zis, :primary_key => 'quwie') do |t| t.column :quwie, :integer, :limit => 4

end

Is it the right way to do it?

Almost. Don't specify the column... just the :primary_key part...

Check the docs for more info.
