问题 I am learning rails using the teamtreehouse tutorial.

I have two models, a users model and a statuses model. I have used devise to create authentication for users, and have included new parameters. They are :first_name, :last_name, and :profile_name. I have created a relationship between users and statuses. Currently the user sign
