Each year there is a competition… Fake Thanksgiving!

The House provides a turkey, and you enter a side or a dessert. (the entry). Then, people vote. the winner gets fame and glory!

The first year, we voted on paper. The next, I built a Rails 1.2 website that tabulated votes. (updated over time).

Let's build a voting machine with Rails as the API but use Ember to keep state and give a better user experience.

The microposts spec starts out with

    @micropost = Micropost.new(content: "Lorem ipsum", user_id: user.id)
 end
