Heroku [WARNING] You provided devise_for :users but there is no model User defined in your application

I have an rails 3 (3.0.9) application working on ruby 1.8.7 with the gem devise (1.4.2) on my computer working perfectly.

I tried to push it on heroku and i got the following error message on application load:

[WARNING] You provided devise_for :users but there is no model User defined in your application
=> Booting WEBrick
=> Rails 3.0.9 application starting in production on http://0.0.0.0:43292

    from /app/vendor/bundle/ruby/1.9.1/gems/devise-1.4.2/lib/devise.rb:409:in `configure_warden!'

The problem comes from devise but i don't know how to fix it. My model User is correctly defined, and it works on my computer... Does anyone know how to fix this ?

Thanks for you help

Check inside your users.rb to make sure that you spelled ':database_authenticable' correctly, this seems to be a common problem with this error.

class User < ActiveRecord::Base
  devise :database_authenticable, :recoverable,
    :rememberable, :trackable, :validatable
  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me
end

Also, I suggest you take a look here, to see how these people fixed the error. http://groups.google.com/group/plataformatec-devise/browse_thread/thread/807f4c6e3475622f

Make sure you have this: 

class User < ActiveRecord::Base

Defined at the top of your user/devise model.

ALso, make sure you run your migrations.

heroku rake db:migrate

In console.
