</div>

class ApplicationController \< ActionController::Base  
helper :all # include all helpers, all the time

model :cart  
model :line\_item

end

I want to use model class only(cart and line\_item), so created without  
scaffold.

I am using cart and line\_item model classes separately and i want to  
initiate this model classes in the application.rb, getting error stating

undefined method model.

I want to use model class only, so created without scaffold.

thanks

That method was removed ages ago and is no longer needed.
