How do I delete a user from db in Ruby on Rails?

While following along with the Ruby simple application, I inadvertently created a couple of users without names and/or email addresses, so now I get 'nil' errors on most pages. How do I delete a user from the database?

rake db:reset is your best friend. In simple terms it will delete your database then rebuild it without users (or attributes) all in one command.

In the rails console you can use

User.delete_all

The

rake db:reset

Is a bit overkill. It drops the entire database and recreates it via the schema.rb. Which is not the same as running the migrations.
