So I am following along with Ruby on Rails 4 Essential Training at lynda.com. I've made it to Ch.6 "Generating Migrations".
My problem is when I run rake db:migrate, I get:
== 20160918162646 CreateUsers: migrating ======================================
-- create_table(:users)
rake aborted!
StandardError: An error has occurred, all later migrations canceled:

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
Why are my databases not migrating?
Migration File:
class CreateUsers < ActiveRecord::Migration
def up
create_table :users do |t|
t.column "first_name", :string, :limit => 25
t.string "last_name", :limit => 50
t.string "email", :default => "", :null => false
t.string "password", :limit => 40
# t.datetime "created_at"
# t.datetime "updated_at"
t.timestamps
end
end
def down
drop_table :users
end
end
