Rspec fails to run because of initialized constant in ActiveAdmin

Question

So I'm trying to run rspec tests with

$ rspec spec/models

but I get this error

/home/kenny/WorkSpace/FeedingForward/app/admin/admin_user.rb:1:in <top (required)>': uninitialized constant AdminUser (NameError) from

Here is the code in admin_user in the admin directory

ActiveAdmin.register AdminUser do     
  index do                            
    column :email
    column :primary_phone

I also have a admin_user class in the models directory

class AdminUser < ActiveRecord::Base
  after_initialize :init

  devise :database_authenticatable, 
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :primary_phone, :password, :password_confirmation,    :remember_me, :notify_by_sms, :notify_by_email
  # attr_accessible :title, :body

  protected

  def init
    self.notify_by_sms ||= false
    self.notify_by_email ||= true
  end
end

It looks like the schema is missing from your test database. Make sure you run the migrations for your test environment too.

RAILS_ENV=test be rake db:migrate
